Tongkat ali is a long-known herbal remedy that has aided many of the health issues that we face today. However, it seems that lately there has been a lot of talk on the topic of tongkat ali.
There are many uses of tongkat ali. As people hear about tongkat ali for the first time and all of its possible uses, they decide to dig deeper to try to find out exactly what tongkat ali root is. One of the most well known uses of tongkat ali is perhaps its use to treat sexual disorders among men. This focuses on erectile dysfunction and low testosterone problems, especially the causes that lead to these occurrences. That is why we decided to create a comprehensive guide to tongkat ali. We hope this will give you the answers that you have been looking for.
What is Tongkat Ali Root?
Tongkat ali is a plant native to few countries in South-East Asia including Malaysia, Indonesia, and Thailand. It is grown in smaller quantities in Laos, Vietnam, and India. The plant also referred to as Eurycoma longifolia, Pasak Bumi, or Long Jack is a tall medicinal plant traditionally used in these regions for its aphrodisiac, anti-estrogen and pro-erectile properties.
This herb is a small flowering tree in the family of Simaroubaceae and genus Eurycoma. It is a slender, unbranched plant and can grow up to 10 meters tall. For centuries, the herb was used in folk medicine as an energy enhancer and tonic in order to increase libido, build muscle, increase sperm count, and to enhance the size of male sex organs.
Decades ago, tongkat ali root was ground into a smooth paste that was then boiled over a low heat for a short period of time. The liquid from the boiled root of the plant was then offered as an herbal remedy for the above-mentioned conditions. In more recent times, tongkat ali has grown to be widely accepted and used across the globe for treating conditions like low testosterone, infertility, and low libido, just to name a few.
Due to advancements in technology, the herb is now extracted in large quantities using facilities that meet the required standards and through a process that is completely controlled. This has made it possible to manufacture a refined and medically safe water-soluble powder that can be added into a diet, encapsulated to serve as a supplement or even used as additives in food and beverages. This, of course, creates an opportunity for you to experience the many beneficial effects of tongkat ali to aid whatever problems you might be facing.
The best processes through which the extract of tongkat ali root is manufactured ensures that the natural composition and efficacy of the herb is retained. Different parts of the plant serve numerous purposes for people, but the root of the plant is believed to be the most beneficial for medicinal purposes.
This is because the leaves and the stems, even if they contain medicinal properties, may be toxic as opposed to the root which is non-toxic and safe for the purposes for which it is used. Although several animal and a few human studies have proven that this herb is safe, natural and potent in treating and preventing the conditions mentioned above, the continued need for additional studies related to the efficacy, safety, and benefits of the herb are ongoing.
Due to the potential efficacy of the herb in treating conditions relating to sexual health, tongkat ali has been referred to as “Herbal Viagra” by those who have used it. You probably have heard about Viagra – the popular drug that enables you to achieve and maintain a healthy erection during sex. Knowing that, you can guess why tongkat ali is referred to as “Herbal Viagra” then, right?
However, it is also important to state that tongkat ali contains other properties that may make it a suitable treatment for malaria, slow metabolism, stress, and even anxiety. Yes, that is true – despite having the role of an “Herbal Viagra”, tongkat ali is found to be beneficial when used for other common health issues as well. In fact, you might be surprised to hear how beneficial this herb can actually be. To tell you the truth – even true believers and followers of today’s modern medicine cannot deny the true power that tongkat ali has. In this post, we will discuss the many benefits that tongkat ali has to improve your health.
Common Names of Eurycoma Longifolia (Tongkat ali)
Eurycoma longifolia is known by many names in different regions around the world. For instance, the plant is known as “Long Jack” in the United States. In Malaysia, tongkat ali has many names including Payong ali, Bedara Merah, Tongkat Baginda, Bedara Putih, Muntah Bumi, Penawar Bias, Petala Bumi, Penawar Pahit, and Lempedu Pahit.
In Thailand, Eurycoma longifolia is called plaa lai phuenk, hae phan chan, lan-don, phiak, and tung saw. In Indonesia it is called Malaysian ginseng, bidara lau, in Laos – tho nan, in Vietnam – cây bá bệnh, in Japan – babi kurus and in Bahrain – langir siam. Other common names of the herb are wonod mondou, payung ali, and umpudumaidu.
Most of these common names for tongkat ali reflect the bitter but beneficial nature of the herb. In Malay, Penawar Pahit is translated as “bitter medicine” or “bitter charm.” The name of the plant in some regions also reflects its physiology.
For example, the common name of this superfood in the South-East Asian region “Pasak Bumi” and “Tongkat ali” has been modified to reflect the color of the root and the bark of the plant which is white/yellow-ish hence “Tongkat ali/Pasak Bumi Putih” or “Tongkat ali/Pasak Bumi Kuning” a red-ish variety of the herb is referred to as “Tongkat ali/Pasak Bumi Merah.” Another similar species of the plant known as Polyalthia Bullata is referred to as “Tongkat Ali/Pasak Bumi Hitam” because of its darker appearance.
What are the Components of Tongkat Ali? (Composition)
Tongkat ali is famous for its amazing benefits, but it is important to note that the reason for this is because of the chemical components of the roots, leaves, and stems of the plant. The herb contains several rich bioactive compounds including eurycolactone, eurycomaoside, pasakbumin-B, eurycomanone, eurycomalactone, and many more.
However, the major chemical components of tongkat ali are alkaloids and quassinoids. Alkaloids are found to offer both antibacterial and anticancer benefits for people who consume food and supplements that contain it and quassinoids offer antiulcer, anticancer, and antiparasitic benefits to its users. [1]
A study conducted on the components of this herb found that tongkat ali contains 65 chemical compounds. The researchers added that some of the quassinoid diterpenoid compounds including eurycomalide B, 13β, 21-dihydroxyeurycomanol, eurycomalide A and 5α, 14β, 15β-trihydroxyklaineanone, were reported for the first time from natural sources. [2]
These compounds were also found via in-vitro trials, to have antimalarial and antiviral benefits. In addition, the authors found that compounds 57 and 58 were shown to have effective antimalarial benefits against the resistant parasite Plasmodium falciparum. Compounds 12, 13, 17, 38, 57, 58, and 59 showed strong cytotoxicity to breast cancer (MCF-7) cell lines, while 12, 13, 17, 18, 36, 38, 59, and 62 exhibited strong cytotoxicity to lung cancer (A-549) cell lines.
How Tongkat Ali Works
Tongkat ali has been used for centuries to manage the symptoms of many health conditions in both young and old individuals. The herb may be beneficial in enhancing sexual performance, regulating the levels of testosterone in the body, and even increasing muscle mass. How tongkat ali works is amazing and it is able to offer these benefits because of its aphrodisiac, antiviral, antibacterial, antimalarial, and antipyretic properties.
Tongkat ali has numerous active chemical components. The chief ones include alkaloids, quassinoids, and eurycomalactone. These phytochemicals are believed to be active agents in stimulating the increase of testosterone levels in the body. It is believed that these chemicals are what has made this herb a famous option for treating low testosterone and other sexual dysfunction in both males and females. [3]
Tongkat ali may aid in improving gut health by decreasing excess acid in the stomach and preventing the development of ulcers. [4] In addition, the herb also helps to prevent the development and spread of cancer by inhibiting the activities of NF-κB and stimulating the death of cancer cells in those individuals diagnosed with this condition. [5]
This herb, if consumed on a regular basis, may be beneficial in preventing and treating male osteoporosis by promoting the growth of bone cells as well as the production of collagen. [6] It also stimulates the activities of the enzyme known as ALP (alkaline phosphatase), which helps in the development of teeth and bones. [7]
How tongkat ali works to provide the numerous health benefits is explained further below.
Health Benefits of Tongkat Ali Root Extract
Tongkat ali is an herb that has an array of benefits to offer to its users. For centuries, the plant has been used in South-East Asian countries for medicinal conditions such as low libido, erectile dysfunction, diabetes, cancer, stress, and anxiety. Although the herb has been primarily used to treat conditions related to sexual health in men, it has been found that extract from the root may also be beneficial for similar conditions in women.
Today, this herb has grown in both usage and acceptability. Studies are being published on a daily basis and many are ongoing with regard to the safety and efficacy of the herb in humans. Emerging information has revealed that tongkat ali root extract may have a lot to offer when it comes to treating several modern-day maladies. Here are a few general health benefits of tongkat ali.
Does Tongkat Ali Boost Testosterone?
Many people ask, does tongkat ali boost testosterone? It is believed that tongkat ali is a testosterone booster for men, but this herb is commonly used to maintain healthy levels of the hormone in both men and surprisingly in women as well. [8] This herb contains chemical compounds like eurycoma lactone and eurycomanone, which are active agents in stimulating testosterone production. [9]
Testosterone is the main sex hormone in men and an unhealthy level of it may lead to different conditions relating to both sexual and overall life activities. [10] The normal level of testosterone naturally starts to decline when a man attains the age of 30, and it is reported that at about 45-60 years old, most men will have only half of the testosterone level they had during their youthful days.
This invariably means that by the age of 60 (or earlier) you will have about half of the general performance you were able to attain in your 20s. However, there may be a way to ensure that your testosterone levels remain at a peak even when you grow older. Tongkat ali may be prescribed for sexual health, as it can help to regulate and boost the level of testosterone in both healthy men and those who are suffering from low levels of testosterone due to one reason or another. [11]
It is when the testosterone declines to quite low levels that certain changes and symptoms start to develop. Because we are talking about the main male reproductive hormone, it is easy to understand the changes that follow testosterone decline. Loss of hair, muscle mass, muscle strength, decreased libido, erectile dysfunction, sleep problems, and depression are just a few of the most common changes that a man experiences due to a drop in testosterone levels. [12]
You see, there is a really good reason or should we say reasons as to why tongkat ali is considered to be a great aphrodisiac and it is referred to as the “Natural Viagra”. Remember this – tongkat ali is probably the most effective testosterone booster that is at the same time, natural and beneficial for the whole body.
How Does Tongkat Ali Increase Testosterone?
To further examine how this herb works to boost testosterone, it is important to state how the body regulates the level of this hormone. The total amount of the testosterone produced by the body is regulated by a process known as the HPG axis (Hypothalamic Pituitary Gonadal axis).
GnRH (Gonadotropin-releasing hormone) is produced by the body’s hypothalamus (located in the brain) and acts as a messenger to tell other hormones what to do. When testosterone levels are below the normal range, GnRH is released, it travels to the pituitary gland and stimulates the release of gonadotropins.
The pituitary gland then releases LH (Luteinizing hormone) that travels to the testes and binds with the Leydig cells within the testes. Through a series of chemical reactions, cholesterol (LDL) is converted to testosterone. Testosterone is then released into the bloodstream.
This testosterone then travels to other places in the body like the liver, muscles, fat, bone, testicles, brain and skin. Here it binds with special cells to carry out the desired effect. [13]
When tongkat ali root extract is ingested, it stimulates the hypothalamus gland to release GnRH. The herb causes the body to do this regardless of the existing level of testosterone in the body. The newly released GnRH then automatically triggers the natural production of testosterone as already described. The level of the testosterone may gradually increase if you continue to take tongkat ali root extract for an extended period of time.
This is unlike other testosterone boosting pharmaceutical drugs that function only to stimulate your Leydig cells to produce more testosterone. which usually causes these cells to stop producing the hormone after a short period of time.
This means that this herb can provide a non-pharmaceutical way for the body to naturally produce more testosterone. Tongkat ali root extract has also been shown to inhibit the production of a protein known as sex hormone-binding globulin (SHBG). This protein is produced by the liver and functions to bind with testosterone, and renders it inactive. By reducing the amount of SHBG in the blood, this increases the amount of free testosterone in your body. This is the testosterone that is active. [14]
The herb allows important hormones to perform their complete functions freely and makes the body become more accustomed to this fact after some time. This is the reason why it is more effective if taken for a longer period of time. For instance, test results used to check the relationship between tongkat ali and testosterone after 1 week showed an impressive result but after 6 weeks the test results are even better. [15]
The main reason why it is advised to take this root extract in regular intervals is that the level of testosterone will gradually and steadily increase until the desired level is attained if the release of GnRH is repeated over and over again.
Testosterone Booster for Men with Late-Onset Hypogonadism
Tongkat ali may be effective in treating, preventing and alleviating the symptoms of late-onset hypogonadism. This is a condition that is prevalent in older men, men that are obese and in men that have other serious medical conditions or are in poor health. Late-onset hypogonadism (LOH) is characterized by a significant reduction in the level of testosterone as well as sexual dysfunction like decreased libido, erectile dysfunction, and spontaneous erections. [16]
The condition often occurs because of a gradual reduction in the level of testosterone in the body. After the age of 30, the level of testosterone gradually begins to decline and may continue to do so as a person grows older. At about 60-70 years, a man may have lost more than half of the testosterone he had during his youthful age. Late-onset hypogonadism naturally results from the steady decline in the levels of testosterone in older men.
A study published in Andrologia found that tongkat ali for late-onset hypogonadism may be beneficial as it improves the symptoms of the condition in individuals suffering from it. The research was conducted on 76 participants diagnosed with the condition. The study authors administered 200 mg of standardized tongkat ali root extract to the participants for a month. The findings of the study revealed that the herb led to a significant improvement in the levels of testosterone and other symptoms associated with male aging.
Another study published in 2016 and conducted on the efficacy of tongkat ali for hypogonadism, found that the herb led to a significant increase in the level of testosterone n the participants. [17] The researchers concluded by stating that the herb may be beneficial in alleviating the symptoms of LOH and the proper management of the condition.
Tongkat Ali for Muscle Building
Tongkat ali may also serve as an active agent when it comes to increasing muscle mass, strength, and stamina. This may be due to the efficacy of the root extract for increasing the level of testosterone in the body. The tongkat ali benefits for muscle building and fitness are the reason why the herb is famous among individuals who live an active lifestyle, and for fitness professions, weightlifters, and bodybuilders. [18]
This means that tongkat ali extract may also be used to enhance fat loss in the body as well as improve athletic performance in both men and women. Several studies have found that the herb may offer this benefit but human trials on the topic are limited. A preliminary study conducted on the efficacy of tongkat ali, found that the extract may be beneficial for increasing muscle mass, stamina, and strength in women who were participating in intensive strength training programs. [19]
The study participants consumed only 100 mg of tongkat ali daily for about twelve weeks. The study was published in the Proceedings of the 2nd International Colloquium on Sports Science, Exercise, Engineering and Technology 2015. Other studies on this topic have shown similar results, plus the fact that the herb may be effective in reducing recovery time after stressful workouts.
Furthermore, a preliminary study conducted on tongkat ali for muscle building was published in 2014 in Phytotherapy Research, found that this herb may be active in boosting muscular strength in older individuals whose strength has naturally declined due to their age. The study was conducted on men and women who were between the ages of 57 and 72 years. [20]
The researchers administered 400 mg of tongkat ali daily to the participants. In addition, they found that there was a significant increase in the level of free testosterone as well as enhanced muscular force.
Tongkat Ali for Metabolism
Tongkat ali may be active in enhancing metabolism. Slow metabolism may occur where there is a lack of a metabolic agent called T3 (triiodothyronine) which helps the metabolic systems and other related glands and organs in the body to perform their normal functions.
If left untreated, slow metabolism may lead to a number of conditions such as fatigue, weight gain, increase in cholesterol, diabetes, high blood pressure, fibrosis, excessive sweat, and poor circulation. [21]
These conditions might not sound as life-threatening ones, but one thing is sure – slowly but surely they all lead to the most common life-threatening conditions including heart attack, and stroke. Several studies conducted on the benefits of tongkat ali for metabolism have found that tongkat ali may be effective in improving gut health and protecting the lining of the stomach. [22]
A study conducted on the efficacy of this herb in preventing carbohydrates intolerance, obesity and insulin resistance found that tongkat ali may be beneficial in enhancing glucose absorption by cells, increasing insulin sensitivity, and lowering the accumulation of lipid in adipose tissue. The study is published in the Journal of Ethnopharmacology. [23]
Tongkat Ali for Stress
Nowadays, it is almost impossible to avoid stress, living the way that we do. Getting little rest, eating unhealthy fast-food, working way too many hours at the office and getting little to no regular exercise has a negative effect on our lives. It all results in way too much stress being put on us. As you may know, stress is one of the many factors that continually endangers our lives increasing the risk of heart attack, diabetes, stroke, high blood pressure, anxiety, and so many other common health issues. But we are in luck because once again, tongkat ali is at our side to help us.
Tongkat ali has been found to have potential efficacy in reducing the level of cortisol in the body. Cortisol is the hormone responsible for regulating the level of stress in the body and a high level of it may lead to stress-related conditions. Tongkat ali for stress is especially important because it boosts the level of testosterone which, in turn, leads to enhanced mood, strength, stamina, and overall body health and fitness.
A study published in the Journal of the International Society of Sports Nutrition found that this herb may be used as a safe and effective stress reliever. The researchers who conducted the study found that taking tongkat ali for four weeks may be beneficial in reducing salivary cortisol levels, increasing testosterone levels, improving mood, as well as reducing confusion, anger, and tension. [24]
Another study entitled “The Effect of tongkat ali on Stress Hormones and Psychological Mood State in Moderately Stressed Subjects” found that the herb may be effective in improving the level of stress as well as other mood parameters. The study analyzed mood state and stress hormones in 63 participants who were administered a standardized hot water-soluble extract of tongkat ali root for four weeks. [25]
The researchers found an improved stress and mood profile, thus suggesting that tongkat ali root extract may be an effective approach to protecting the body from the unpleasant symptoms that accompany stress as well as conditions that may develop if chronic stress is left untreated. Specifically, there was a significant improvement in testosterone level (+37 percent), cortisol level (−16 percent), Anger (−12 percent), Tension (−11 percent), and Confusion (−15 percent).
Tongkat Ali as an Anxiety Remedy
This herb has been used as a remedy for anxiety disorders. In contemporary times, anxiety disorders are prevalent and they are believed to be one of the most common types of psychiatric disorders. However, these conditions are usually diagnosed based on the symptoms reported by the patient and can be caused by the use of drugs such as amphetamines, cocaine, and corticosteroids.
Anxiety may also be worsened by the use of caffeinated drinks, stimulants, excessive dietary supplements such as SAM-e or even by certain medical conditions. Individuals diagnosed with a generalized anxiety disorder (GAD), often experience fear and the worry of imminent harm. Taking tongkat ali as an anxiety treatment is beneficial because the herb can provide its users with better moods, calm feelings, and a sense of control over their affairs.
A recent study conducted on moderately stressed individuals revealed that this herb may be beneficial in reducing the level of cortisol in the body as well as confusion, tension, and anger. [26] It is important to state that all of these are major contributing factors to anxiety. Another study conducted on the efficacy of this herb in enhancing mood state in mice found that it led to a significant increase in exploratory behavior and a reduction in the frequency of aggressive/fighting episodes. [27]
Tongkat Ali for Diabetes
Diabetes is listed among the most common health issues today. According to the latest statistical data from the Centers for Disease Control and Prevention (CDC), there are 30.3 million cases of diabetes in the United States and another 84.1 million individuals over the age of 18 have prediabetes. [28] With this disease quickly approaching epidemic levels, it is not surprising that people are looking for alternative treatments. Once again, we are witnesses of the numerous beneficial effects that tongkat ali presents!
Tongkat ali may be prescribed to treat type II diabetes. It is believed that the herb plays a key role in helping the body maintain a healthy level of blood sugar. A study conducted on the benefits of tongkat ali for diabetes found that the herb may be effective in regulating blood sugar levels in the body. [29]
The researchers added that the study participants reported no adverse side effect. However, the herb works better with people who make some lifestyle changes like regular exercise, adequate sleep, frequent exposure to sunlight, and a reduction in the consumption of carbohydrate.
Using Tongkat Ali for Treating Malaria
Tongkat ali was traditionally used in ancient folk medicine as a treatment for malaria. Today, the herb has also been used as an alternative treatment for this condition. So you see, this is not a new herbal remedy and it could aid in the fight against this awful disease in the countries where, unfortunately, malaria continues to take young lives. Several human and animal studies have found that this herb may offer quick relief from malaria. However, the need for additional research on the benefits of using tongkat ali for treating malaria is imperative before trying this as a remedy.
A study conducted on the chemical composition of tongkat ali found that the herb contains 65 medicinal compounds. [30] Compounds 57 and 58 were found to be effective in treating malaria. The researchers also revealed that the compounds showed effective antimalarial activity against the resistant Plasmodium falciparum which is believed to be the deadliest species of malaria-causing Plasmodium in humans.
Tongkat Ali for Mood Enhancement
Tongkat ali may be beneficial for enhancing mood by giving its users a calm and relaxing feeling. This herb may also be effective in helping to treat and prevent conditions that may dampen the mood such as depression, anxiety, tension, anger, and confusion. In addition, tongkat ali provides its users with a feeling of happiness and overall well being of the body.
A study conducted on the benefits of tongkat ali for mood enhancement and stress hormones in moderately stressed subjects found that this herb may be effective in improving mood state. [31] The researchers added that the herb led to a decrease in the level of cortisol, tension, confusion, and anger as well as a significant increase in the level of testosterone.
Tongkat Ali for Sexual Health
The majority of individuals who use tongkat ali do so because of the sexual health benefits the herb has to offer. The root extract contains aphrodisiac properties thus making it a great choice for helping conditions such as low libido, erectile dysfunction, and other sexual health-related conditions. Tongkat ali was traditionally prescribed as a remedy for these types of conditions and today it is widely accepted and used in the modern day.
Although this herb is commonly adopted to help conditions associated with the sexual health of men, it is important to state that tongkat ali root extract is also beneficial as an aid for certain conditions in females such as hyperandrogenism, osteoporosis, breast cancer, hormonal imbalance, and several others. [32] Here are a few benefits of tongkat ali for sexual health.
Tongkat Ali for Erectile Dysfunction
A common sought after benefit of tongkat ali is its potential efficacy and possible remedy in treating erectile dysfunction in men. This condition is characterized by the inability to get as well as maintain an erection. Erectile dysfunction brings on numerous difficulties in one’s life – depression, anxiety, sleep problems, intimacy problems, and relationship problems. The potential issues are numerous. It is also one of the most common sexual disorders among men nowadays. Luckily, tongkat ali is a natural aphrodisiac and that is for a very good reason.
The treatment and effective management of erectile dysfunction are important to the sexual, reproductive, and the overall health of the male body. This is because the sexual performance, sexual satisfaction, and fertility of a male depend on attaining and maintaining erections within a reasonable period of time. A quality intimate relationship and family balance are also heavily dependent on being healthy in this aspect of life.
Tongkat ali root extract is believed to be effective in treating erectile dysfunction as well as improving erections for men who are not suffering from the condition. The herb performs this function by increasing the levels of testosterone which in turn leads to improved sexual health, increased energy, endurance, and stronger erections.
The researchers of a study published in Evidence-Based Complementary and Alternative Medicine found that tongkat ali led to an enhanced overall sexual performance in the study participants who took tongkat ali for about twelve weeks. [33] Another study published in Translational Andrology and Urology found that tongkat ali root extract resulted in increased libido, improved erectile function, increased sperm quality and quantity as well as loss of fat mass in overweight participants. [34]
Tongkat Ali and Libido
Low libido can most commonly be caused by low testosterone levels, depression, anxiety and stress. Tongkat ali has been prescribed as an herbal remedy for a low sexual drive. Due to its aphrodisiac properties, the herb is believed to be beneficial in increasing libido. There are several animal studies that have investigated the efficacy of this herb for improving sexual drive in individuals suffering from low libido. Most of these studies found that there was an enhanced sexual drive in the animals. There are also numerous user reviews that speak of their excellent experiences with tongkat ali in their fight against low libido.
A study conducted on the efficacy of tongkat ali, for treating low libido in middle-aged retired male breeder mice, found that the mice who were administered tongkat ali root extract recorded a significant increase in mounting frequency with female mice. [35] The researchers also found that this category of mice showed an improvement in genital licking and sniffing due to higher sex drives. Although other male mice who were not given the herb went about their normal daily activities while those that took tongkat ali, showed more interest in their female counterparts.
There are several other animal studies that have been conducted on the relationship between tongkat ali and libido but it is not clear if the findings of the studies can be extended to humans. Only a few human studies have been conducted on the benefits of tongkat ali for libido. [36]
Men who have used this herb have reported that it was effective in boosting sexual drive as they noticed stronger and longer erections, increased stamina, and fullness in the testicles. This is believed to be as a result of an increase in the levels of testosterone in the body.
Tongkat Ali for Fertility
Tongkat ali is prescribed as a treatment for infertility. Several studies conducted on the efficacy of this herb for infertility found that the herb may be promising in reversing and preventing this condition. A study conducted in 2010 found that taking 200 mg of tongkat ali for fertility for three to nine-month resulted in increased sperm volume, enhanced semen concentrations, as well as a regulated semen morphology, and semen motility.
In addition, the researchers found that the therapy resulted in spontaneous pregnancy in about 11 of the study participants partners. [37] Another study conducted on tongkat ali and Infertility found that the herb leads to about 15 percent pregnancy in the study participant’s partners. Most people who purchase the herb do not do it for fertility reason, but this is a plus for people who are struggling with infertility.
The effectiveness of tongkat ali in treating infertility is not surprising considering the plant’s potency in reversing conditions relating to the reproductive organ. It is no news that better sex drive, increased sperm count and sperm quality, better erections, and enhanced performance will significantly increase the chance of conception. [38] However, it is advised to take precautions if you are taking tongkat ali and you are not ready for children.
Benefits of Tongkat Ali for Men
When tongkat ali is mentioned, the first thing that crosses the minds of individuals who are familiar with the herb is that it is a remedy used to boost sex drive and regulate vital hormones in males such as testosterone, as well as its role as the “Natural Viagra”.This is because, for the longest time, this herb was used primarily for regulating hormones and increasing libido in men. In recent times, the herb is mostly used by men because of its effectiveness in improving their overall health and therefore their life. [39] Here are few benefits of tongkat ali for men:
Tongkat Ali for Testosterone
As mentioned above, as men age, their testosterone levels begin to decline. Several other hormones in the body may also decline and even come to a stage where the man may lose the majority of the vitality he had during his youthful years. This condition is referred to as andropause and is characterized by symptoms such as mental lethargy, increased body fat, low libido, fatigue, and many others.
This phase may be a very frustrating one for men and many may feel confused as to a way out. Tongkat ali contains properties that make the herb a great natural choice for conditions relating to the sexual health of men as well as their overall well-being. [40]
A study conducted in 2014 on the effectiveness of tongkat ali root extract on testosterone levels in men found that it may be a safe alternative to testosterone replacement therapy (TRT). [41] TRT is a process utilized to treat a condition known as TDS (testosterone deficiency syndrome).
The condition is characterized by several unpleasant symptoms including increased body fat mass, low libido, fatigue, male osteoporosis, and erectile dysfunction, just to name a few.
Taking tongkat ali for testosterone to prevent or treat the condition is especially important as it is reported that nearly 70 percent of men will experience at least one aging males’ symptom in their lifetime. [42]
TDS is a condition that naturally results from the age‐dependent decline in the level and concentration of serum testosterone in the body. The concentration of the hormone may decrease by up to 50 percent in men who are older than 60 years compared to those who are younger. However, this rapid decline in the levels of serum testosterone may also be caused by certain medical conditions such as diabetes, high blood pressure, metabolic syndrome, or obesity.
Researchers have found that tongkat ali may serve as a safe alternative to TRT as it restored the level of serum testosterone to a normal range, improved bone, and sexual health, as well as the overall physical condition of participants diagnosed with TDS. The researchers added that the herb had no significant side effect on the study subjects. [43]
Tongkat Ali for Male Libido
As already mentioned above, this herb is primarily used to treat low libido in men. Many men are struggling with decreased sex drive and poor sexual performance and satisfaction. This can be frustrating and may have a negative effect on other areas of their life. Tongkat ali has been found to be a safe and potent natural remedy for a low libido in men.
A study conducted on the effectiveness of the herb in treating low sex drive found that it is beneficial in increasing the level of free testosterone in the body, which invariably means increased libido, sexual performance, and sexual satisfaction. [44]
Even though many users of tongkat ali root extract reported a significant increase in sex drive after taking the herb for two weeks, it is recommended to take it for 1-3 month for a long-lasting effect.
Tongkat Ali for Sperm Quantity and Quality
The tongkat ali health benefits for men may also include increasing sperm quantity and quality. In recent times, several technological factors including GMO’s, cell phones, medications, manufactured food, and many others may lead to a significant decrease in sperm count. Cases of infertility in men is becoming more prevalent by the day. [45]
Tongkat ali for low sperm count may be helpful in preventing and treating infertility in men according to the findings of numerous animal and human studies conducted on the topic. A study conducted on 75 male partners of couples diagnosed with idiopathic infertility found that the herb led to a significant increase in sperm concentrations, semen volumes, and an improved rate of sperm motility and sperm morphology. [46]

The condition is common during the menopause and in older women. It is characterized by fragile, brittle and weak bones. Tongkat ali has been found to be beneficial in increasing the level of testosterone in the body which invariably leads to a significant improvement in the health of bones.

How to Take Tongkat Ali
Deciding how to take tongkat ali usually differs from culture to culture. The root is the part of the plant commonly consumed for medicinal purposes even if other parts are also believed to contain medicinal properties. An extract from the root is believed to be beneficial in treating many conditions and can be consumed in different forms including tea, coffee, tincture, powder, and even capsule.
Today, tongkat ali supplements are added to food, beverages and energy drinks. Although taking the herb in this form is not a bad idea, it is believed that it is not as potent as supplements that are encapsulated. You may also find it difficult to calculate your dosage of tongkat ali when taken in these forms compared to when you consume the capsule. Here are a few common ways to take tongkat ali root extract:
Tongkat Ali Extract
As already mentioned above the root is the part of the plant commonly used for medicinal purposes. Centuries ago, the root is grounded, boiled, and sieved by herbal physicians. The water from the boiled root is then offered to patients to treat the condition they desire to remedy. However, with the recent advancement of technology things are different but you can still boil the root and ingest the water if you so choose.
It is important to know that this is not recommendable as the root may be contaminated by heavy metals and other pollutants in the soil where the herb has grown. Today, a good tongkat ali extract from the root is obtained through a controlled process with world-class facilities that ensure that the natural component and potency of the herb is not altered.
These companies also take active steps to ensure that the herb does not contain heavy metals or other contaminants. Furthermore, the best products available on the market today are standardized so they have consistent potency and efficacy. For this reasons, it is believed that tongkat ali root extract that is carefully manufactured through the appropriate extraction processes is safer and more effective, compared to products directly harvested from the field.
Tongkat Ali Supplements
Tongkat ali is widely used across the globe as a dietary supplement. This is because of the amazing health benefits this herb has to offer. It has been found to offer an array of benefits to both the young and the old, men and women. The herb is prescribed to correct hormonal imbalance, increase strength, reduce stress, and assist with a long list of medical conditions. What is the best Tongkat ali supplement? A standardized tongkat ali root extract with the highest concentration is the most potent and may be best depending on your condition.
There are a few different ways that tongkat ali supplements are taken:
- Powder
- Tea
- Tincture
- Capsules
Let’s learn a little more about each.
Tongkat Ali Powder
The herb is mostly manufactured in a powdered form. How to use tongkat ali powder differs from person to person. Many companies supply it to consumers in this form who in turn choose to either add it to milk, drinks or solid food depending on individual taste.
Additionally, tongkat ali root extract is famous for its bitter nature and it takes a lot of courage to consume it in a powdered form. Other food and beverages company have adopted this form of the herb, which is then used as an additive in the product they manufacture.
Tongkat Ali Tea
Another form in which tongkat ali root extract can be consumed is as tea. The companies who produce the extract in the form of tea usually manufacture or purchase it in a powdered form that is then packaged into tea bags. The tea can be consumed hot or cold for its soothing and healing benefits.
Tongkat ali tea may be a great idea for individuals who do not like to take capsules or who are not comfortable with the bitter nature of the powder. Refined sugar, honey or other artificial sweeteners may be added depending on your taste.
Tongkat Ali Tincture
Tongkat ali is also available in a tinctured form. This form is also preferred by some individuals who do not like swallowing pills. A few drops of tongkat ali tincture on the tongue, under the tongue, in drinks, or any other way based on the preference of the user will suffice. The tincture is manufactured in two different ways namely: alcohol base and non-alcohol base.
Both products are believed to be as equally effective but the latter may be preferable to individuals who do not take alcohol. This is based on lifestyle choices or religious grounds. This is because the non-alcohol based tincture is manufactured using plant-based vinegar.
Tongkat Ali Coffee
Another form of consuming tongkat ali is with coffee. The herb is specially mixed with coffee during the manufacturing process to offer dual benefits to individuals who consume it. Tongkat ali coffee may also be purchased for a cheaper cost.
However, it is important to state that benefits of tongkat ali coffee may not manifest, as the herb may not be as effective in this form, compared to the powder or capsule form. It may not offer the benefits you were looking to achieve by consuming the coffee. Coffee with tongkat ali is prepared the same way as the traditional coffee.
Tongkat Ali Capsules
Capsules are the most common and most popular way to consume tongkat ali. The powdered herb is encapsulated and provides an easier way to know the precise dosage you are consuming. This is believed to be the safest and the most potent way of consuming tongkat ali. The capsule form also rules out the need to consume the bitter powdered extract directly. Tongkat ali capsules are easier to consumed and proper storage is usually provided by the seller.
Tongkat Ali Dosage
For a maximum result, it is advised to follow a tongkat ali dosage guide. It is reported that a 600 mg dose of a standardized 200:1 tongkat ali root extract twice daily has been shown to be both safe and effective. This dose can assist with conditions like low libido, erectile dysfunction, late-onset hypogonadism, stress, anxiety, osteoporosis, and many others.
This dose is generally recommended notwithstanding the condition you intend to manage with tongkat ali supplement. A dose below 600 mg twice daily may not be as effective and taking more than the recommended dosage of tongkat ali may lead to some unpleasant side effects, like diarrhea, vomiting, insomnia, and several others. For better results, it is advised to take tongkat ali supplement on a regular basis.
Tongkat Ali Dosage Cycling
For the best result and to prevent your body from becoming dependent on the herb, it is advised to cycle your dosage of tongkat ali root extract.

You may also choose to take the herb for 6 weeks and then take a two-week break before resuming your dosage.
However, 5 days on and 2 days off is believed to be the best way of cycling this herb. Many tongkat ali users reported that they fear cycling may mean starting all over again but this is not completely true. Tongkat ali dosage cycling helps the body to build up the levels of testosterone naturally without becoming dependent on the herb, plus you will not have to start over again every week.
How to Buy Tongkat Ali?
When buying tongkat ali there are a few factors to put into consideration so as to ensure that the product you are buying is safe and effective for your use. Tongkat ali has been used to aid many health conditions but it is important to note that you may not experience the benefits of the herb if you don’t buy a good product.
Some people complain that they tried tongkat ali from different brands with no effects. This may be because they are not buying a genuine and potent product. This section will furnish you with a few key things to check for when looking to buy a genuine, safe and highly concentrated tongkat ali extract.
What to Look For When You Buy Tongkat Ali
First, when buying tongkat ali, it is best to go for the root extract of the plant. There are extracts from the other parts of the plant (stem and leaf) on the market but the root is mostly used. This is due to the non-toxicity of the root extract which is unlike those of other parts of the plant.
Also, out of all the forms of taking tongkat ali extract, capsules are the easiest to ingest compared to other forms like tongkat ali powder that has a bitter taste making it difficult to swallow. With tongkat ali capsules, it is also easier to track your dosage and storage and bringing it with you during the day is more convenient.
But, even with the capsules, there are different concentrations like 50:1, 100:1, and 200:1 available on the market. Consider going for tongkat ali supplement with a high concentration for a better chance of enjoying the full benefits the herb has to offer.
However, high concentration doesn’t always translate to high potency since there is no way for you to confirm the claims of the manufacturer. For this reason, it is advised to go for a highly concentrated product while also ensuring that it is standardized for the maximum effects.
Read on for more information on the things you should look out for when buying tongkat ali.
Tongkat Ali Color
You may have been told that when buying a genuine tongkat ali, you should ensure that the supplement is of a certain color but this is not completely true. The color of the herb varies depending on several factors, chief among them being the extraction process used to manufacture the final product
Tongkat ali color may range from a creamy beige to dark brown or even black. Manufacturers that supply the beige tongkat ali powder argue that the product of those that supply the brown/black tongkat ali is not genuine and vice versa.
It is also argued that tongkat ali with a beige appearance cannot be authentic since the color signifies that it has passed through an extraction process that involves the use of high temperature. In contrast, history has it that traditional Indonesian tongkat ali manufacturers produce dark-colored supplements due to longer extraction time. This probably led to oxidative damage thus resulting in a darker color of the final product.
Modern extraction methods usually complete the process within a short period of time thereby leading to the production of a clear tongkat ali powder. Furthermore, some manufacturers employ a method that involves grinding the root of the tongkat ali plant instead of boiling the root in water and subsequently extracting its active components. This method will also lead to the production of light-colored extract.
Chinese suppliers of tongkat ali are capable of controlling the color of the final product during the extraction process. This simply means you can’t determine the authenticity of tongkat ali powder based on color since this suppliers can tweak the color of the final product to appear the way they want.
Malaysian Tongkat Ali Extract Vs Indonesian Tongkat Ali Extract
This is one of the most popular tongkat ali topics that consumers scrutinize quite often. Tongkat ali grows in the wild in Malaysia and Indonesia. It’s from these two countries where most of the raw materials come from. Sellers that source their products from Indonesia will tell you that you should only buy tongkat ali from Indonesia. Is this true? And if so, why?
First, it is important to state that both Malaysia and Indonesia Tongkat ali are effective and the best one for you will be dependant on your preference.
Sometimes those who sell tongkat ali from Indonesia point to the fact that it has been proven that some products sold as tongkat ali from Malaysia do not contain tongkat ali at all. A 2015 study conducted in Malaysia analyzed major tongkat ali brands and discovered that a shocking 41% of products did not contain any tongkat ali. [66]
Tongkat Ali Extract 100:1 or Tongkat Ali Extract 200:1
As already mentioned, there are different concentration ratios of tongkat ali root extract on the market including 50:1, 100:1 and 200:1. Out of these, the 100:1 and 200:1 ratio are the most popular among tongkat ali users.
The concentration ratio of a product informs buyers on how much tongkat ali extract is used to make the final product. For instance, if the label state that the concentration ratio of the product is 50:1, it simply means 50 gram of tongkat ali root is used to produced 1 gram of the supplement.
For this reason, one may conclude that products with higher concentration ratios should be more potent compared to those with low ratios. Unfortunately, there is no way for buyers to confirm that the concentration ratio claimed by the manufacturer is really correct.
While some tongkat ali users report that products with 100:1 concentration ratio was effective for their intended use, others report that they noticed faster results when taking products with a concentration ratio of 200:1.
Tongkat ali 200:1 (200 grams of root used to produced 1 gram of extract) is considered to be the best since it has the highest concentration you can find on the market. It is advised to avoid products that fail to specify a concentration ratio. The recommended dose of tongkat ali 200:1 is about 600 mg twice daily.
The Best Tongkat Ali is Standardized Tongkat Ali Root Extract 200:1
Since there is no practical way to confirm the concentration ratio claimed by a tongkat ali root manufacturer, standardization may be your only way to determine the potency of the product. A study conducted on the chemical compounds contained in tongkat ali root extract found that eurycomanone is the major active components of the herb. [67] It has also been confirmed by many studies to be the key component behind the many health benefits of tongkat ali. [68], [69], [70], [71], [72]
A meager number of manufacturers standardized their product for higher potency. Standardization is a process where eurycomanone is quantified and identified by a laboratory process known as HPLC. Tongkat ali root extracts that are standardized are expected to contain more than 1 percent of eurycomanone for higher potency.
Some tongkat ali users have complained that they took the highest concentration (200:1) of tongkat ali with no effect at all. This is probably due to the fact that the supplement is not standardized. Also, a high concentration ratio claimed by a manufacturer doesn’t always translate to a high potency as mentioned before.
Where to Buy Tongkat Ali Extract?
This brings us to the question, where can I buy tongkat ali extract? You are probably looking for information on the best place to buy a pure and genuine tongkat ali root extract. There are many places where you can buy tongkat ali supplement. However, it is important to state that there are a few important things to consider when choosing where to buy the supplement.
Many pharmaceutical stores like GNC and Watson’s list tongkat ali supplements for sale but the tongkat ali extract they sell may not be as potent and concentrated as you would want them to be. Use the above suggestions to vet them before you buy them.
Also, the tongkat ali supplement may not be offered at a budget-friendly price considering the fact that these types of dealers usually have to cover high overhead costs associated with running physical retail stores. You can also find tongkat ali root extract in traditional herbal supplement stores but you may experience similar issues associated with pharmaceutical stores as these types of stores do not buy large amounts and therefore can’t get the product as cheap as the larger pharmacies and stores.
Buying Tongkat Ali Online
At this juncture, you may want to consider buying tongkat ali root extract from an online store dedicated to providing customers with a genuine, and potent supplement for a competitive price. However, there are a few key things to look out for when deciding which online retailer to buy from.
First, you should carefully look at the reviews and ratings of the retailer by previous buyers. This would help you to determine whether the claims of the manufacturer are correct. You will usually find reviews by past customers on the website of most retailers. If the retailers sell on large online marketplaces like Amazon or Lazada, those are also good places to find reviews.
An advantage of buying supplements from online stores is that you can simply scroll through the products listed in a particular store from the comfort of your home and select the one that works best for you. This gives you a chance to carefully check the pros and cons of the products, check their reviews and also to easily compare the price with that of other products on the market. Also, if you are looking to have your packages delivered discreetly, you can choose a website that delivers your order discreetly to your doorstep.
