Tongkat Ali does not appear to have adverse effects on the liver, kidney and other health-related complications based on doses up to 600mg per day. Most studies and clinical trials on Tongkat Ali range from 2 weeks to 36 weeks with no reported negative effects on health.

Several studies have shown that daily consumption of Tongkat Ali helps to regulate and restore your testosterone levels by freeing up more “usable” or also known as free testosterone.

Placebo-controlled group studies by Food & Nutrition (2021) and Phytotherapy Research (2014) showed improvement in free testosterone of up to 122% depending on the daily dosage.

Here is what we found:

• 100mg – 5.1% increase after 12 weeks
• 200mg – 16.9% increase after 12 weeks
• 400mg – 61.2% increase after 5 weeks (male)
• 400 mg – 122% increase after 5 weeks (female)

Another study published in the Journal of International Society of Sports Nutrition by Dr. Shawn Talbott and Julie Talbott showed a testosterone increase of 37% (in both men and women) after four weeks of consuming Tongkat Ali.

Daily consumption of Tongkat Ali may deliver a stronger immune system. A clinical trial by a group of Japanese scientists showed a significant increase in T-Cell and CD4+ T-Cell count after daily consumption of 200mg Tongkat Ali for 4 weeks by 82 males. 

Results of taking Tongkat Ali supplements showed 69.6% increase in T-Cell count and 80% increase in CD4+ T-Cell count after four weeks. A Tongkat Ali patent was filed in the US in 2016 soon after the breakthrough discovery in 2014.

Yes, Tongkat Ali is one of the best endocrine supplements to support a healthy endocrine system. Multiple studies showed Tongkat Ali’s effect on key hormones such as testosterone, norepinephrine, progresterone, estrogen, Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), Growth Hormone (GH), renin and angiotensin, cortisol and dopamine which exists in your endocrine system.

The endocrine system comprises our reproductive system, central nervous system, immune system, sympathetic nervous system, urinary system and many others.

Tongkat Al affects Pituitary Glands, Adrenal Glands, Thymus Glands in the endocrine system. These glands secrete hormones such as testosterone, DHEA, estrogen, etc to regulate bodily functions, including growth, reproduction systems, and metabolism.

Tongkat Ali may be used to prevent the risk of gout (caused by high uric acid in your body). Tongkat Ali showed a reduction of uric acid in a clinical study on 105 men using 100mg – 200mg Physta® Tongkat Ali extract over a period of 12 weeks.

Tongkat Ali may be used as a herbal remedy to manage hangovers as it regulates your cortisol levels from alcohol consumption. Studies have shown that Tongkat Ali lowers your cortisol and improves your mood.

Studies have shown that Tongkat Ali plants found in Malaysia contain crude proteins between 15.5% to 39.9%. The amount of crude protein varies on the soil quality and Tongkat Ali in the state of Pahang usually has higher crude protein content.

Physta® Tongkat Ali contains high crude protein content, averaging more than 22% due to the standardized water extraction technology.

Tongkat Ali (Eurycoma Longifolia) does not contain gluten, or wheat proteins.

Gluten or wheat proteins is found in grains – such as wheat, barley, rye, and a cross between wheat and rye called triticale. These include any species of wheat (i.e durum, spelt, khorasan, emmer and einkorn), barley, rye and some oat cultivars. 

Studies showed that Tongkat Ali contains crude proteins and amino acids, and not wheat protein.

As Tongkat Ali is gluten-free, this makes it ideal if you have celiac disease and other medical conditions associated with gluten.

Tongkat Ali benefits women’s health in many ways; increasing muscle mass, fat loss, improved mood, improved sexual libido and potentially looking younger too. The effects of Tongkat Ali on women were largely due to its ability to restore testosterone, DHEA and estrogen (estrodial) and balance cortisol levels. Tongkat Ali is commonly used by female athletes, women in their 40s or those who experience pre or post-menopausal symptoms.

Tongkat Ali has natural anti-aging properties that may affect skin elasticity and tightening from increased DHEA and testosterone. A 2021 clinical study on 105 men between 50-70 years showed an increase of dehydroepiandrosterone (DHEA) by 11% after consuming 200mg of Tongkat Ali for 12 weeks. Another study showed free testosterone increase of 600% in women and 582% in men after consuming 50mg of Physta® Tongkat Ali with multivitamins for 24 weeks.

Similarly, the principle of DHEA and testosterone treatment have contributed to youthful appearance and better skin for many years. Over the counter DHEA cream has been shown to thicken and tighten skin by dermatologists whilst testosterone cream and HRT improves skin tightening and skin elasticity.

Many consumers are beginning to consume Tongkat Ali as a natural DHEA supplement with positive results from better appearance, reduced facial lines, stronger facial definition and youthful looks. DHEA is dubbed as the “fountain of youth hormone” by Dr. Susan Richards from Stanford University in her book on natural wellness.

Yes, Tongkat Ali is proven to benefit health in many areas of the endocrine system with more than 300 clinical evidence, tests and studies on humans. More than 1,000 humans have been tested with Tongkat Ali from various demographics and medical history, with new research studies being published each year.

Most lab-tested and clinically tested Tongkat Ali contain mercury less than 0.05 ppm, which is far below USFDA’s maximum permissible limit of 1.0 ppm of mercury.  Based on FDA’s findings on mercury levels, Tongkat Ali has much lower mercury levels than Tuna (1.478 ppm), Mackerel (1.67 ppm), and Cod Fish (0.98 ppm), or even Oyster (0.25 ppm). Mercury is also found in most vegetables and fruits grown in some countries.

FDA has not issued any warnings on mercury levels found in Tongkat Ali in the last 30 years.

Yes, Tongkat Ali may benefit sports and athletic performance in various key areas. Multiple clinical trials and research showed improved anaerobic peak power, muscle strength (limb and back), lean muscle mass, faster muscle recovery time from sports injuries and ergogenic effects from efficient production and usage of energy.

Tongkat Ali has effects on dopamine. A recent study on the consumption of 50, 100, 200, 400, or 800 mg of Tongkat Ali showed an increase in brain cortical and hippocampal dopamine by almost 100%.The boost of dopamine and reduction in cortisol from Tongkat Ali helps improve the overall mood. At the time, the reduction in stress was also reported in studies and from real-world experiences.

There is a long list of scientific studies related to Tongkat Ali’s efficacy in regulating and promoting free testosterone levels across various age groups of people in their 20s, 40s and 70s.

Some of these studies include randomized with placebo-controlled groups to further validate Tongkat Ali’s efficacy in boosting testosterone.

Several testosterone-related studies on young men, middle-aged men and senior men including women from 2010 – to 2021 showed significant improvement depending on the daily dosage.

Tongkat Ali may improve women’s libido from higher DHEA levels.

A clinical study on Tongkat Ali showed reported an increase of dehydroepiandrosterone (DHEA) by 11% in 12 weeks based on 200mg of Tongkat Ali daily.  Other studies showed that DHEA treatment can increase sexual desire in women diagnosed with Hypoactive Sexual Desire Disorder (HSDD).

DHEA is reported to deliver a dramatic sexual awakening effect with increased frequency of sexual thoughts, sexual interest, and satisfaction in women.

This makes Tongkat Ali a popular choice amongst women seeking a DHEA-inducing natural supplement to boost libido. 

Tongkat Ali improves sleep quality by lowering your core body temperature during sleep. A 2022 study by the National Institute of Advance Industrial Science and Technology Japan reported that Tongkat Ali supplementation improves sleep quality with a lower Core Body Temperature (CBT) recorded after four weeks. This study was published published in the Journal of Nutritional Science & Vitaminology and a patent was submitted to use Tongkat Ali as sleeping-improving agent.

Yes, Tongkat Ali was reported to improve erection time (+162%) and erection hardness (+39%). This evidence was backed by a study published in the Journal of Evidence-Based Complementary and Alternative Medicine which showed improvement in erection hardness and erection time, including sperm motility and concentration amongst others.

Tests on daily consumption of 300mg of Tongkat Ali on 26 test subjects (with Placebo group) aged 40-64 years of age showed sufficient evidence that Tongkat Ali can be used safely as a natural viagra.

Tongkat Ali’s use as a libido for men attracted many medical views and discussions as it also offers a wide range of other scientifically-proven benefits beyond its single use as natural viagra.  

Tongkat Ali does not raise cortisol. A clinical study on Tongkat Ali in 2013 showed a reduction of cortisol by 16% in moderately stressed test participants (both men and women) based on 200mg per day of Tongkat Ali for 4 weeks.

In another clinical study published in 2021 with 103 test participants (who are not moderately stressed), Tongkat Ali was found to reduce cortisol by 11.2%; from 284.6 (nmol/l) to 252.8 (nmol/l) after 12 weeks. This study was based on 200mg per day of Tongkat Ali.

Yes, Tongkat Ali increase DHEA (dehydroepiandrosterone). A randomized placebo-controlled group study on 105 test participants showed an increase in DHEA levels based on 200mg of Physta® Tongkat Ali daily consumption for 12 weeks. The study reported that the increase in DHEA was possibly due to high protein content (12-45%) and high eurypeptides from Tongkat Ali standardized bioactive ingredients. 

DHEA (dehydroepiandrosterone) is a steroid hormone available in supplement form that is sometimes used to increase testosterone levels. Produced naturally by the adrenal glands, DHEA is converted by the body into testosterone and other sex hormones.

Yes, most recent Tongkat Ali clinical trials, tests and research studies have been performed on humans (both men and women). Close to 1,000 test participants and volunteers have participated in clinical tests involving Tongkat Ali in the last 20 years. Approximately only 10% of Tongkat Ali studies are tested in vitro on animals (mice and rats). Similar to the approach taken by pharmaceutical drugs, companies like Pfizer said that "the use of animals in research is currently an essential component of the drug discovery process”.

There are more than 300 research papers and 30 clinical trials on Tongkat Ali that have been validated by qualified scientists, medical professionals, and certified researchers in the last two decades.

Human-tested clinical trials have provided sufficient evidence of Tongkat Ali’s effectiveness to benefit health in many ways. Scientists such as Dr. Annie George, Dr. Shawn Talbott, Professor Dr. Anthony Sinskey, Professor Hirokawa and others have long dedicated their research to Tongkat Ali for decades.

You can gain maximum results from Tongkat Ali with a combination of diet and regular exercise. A study by the University of Santa Catarina Brazil in 2021 showed that daily consumption of Tongkat Ali with a 60-minute exercise 3 times a week brings the most improvement in ED, sexual satisfaction and desire.

Tongkat Ali work through several mechanisms through hormonal activation via the endocrine system. The primary endocrine system controls the release of hormones such as testosterone, testosterone, norepinephrine, progresterone, estrogen, Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), Growth Hormone (GH), renin and angiotensin, cortisol and dopamine via Pituitary Glands and Adrenal Glands.

Here is how Tongkat Ali work and the science behind it.

1. Tongkat Ali contains ingredients such as eurycomanone,  a family of quassinoids and alkaloids that work by activating hormone-inducing actions in our body.
2. Tongkat Ali activates Luteinzing Hormones (LH) that stimulates the Leydig cells in your testicles to produce testosterone. In women, the Luteinizing Hormones (LH) triggers the creation of steroid hormones from the ovaries and that helps with menstrual cycle and ovulation.
3. Tongkat Ali decreases the sex hormone binding globulin (SHBG) which in turn, delivers higher production of testosterone. SHBG rises when your testosterone level is low.
4. At the same time, Tongkat Ali reduces cortisol, the stress hormone that lowers the testosterone in our body.
5. The mechanism of actions collaboratively increase production of “free testosterone” in our body.
6. Therefore, increased free testosterone from Tongkat Ali provides more energy, improved mood, improved sexual libido, more sperm motility, stronger muscle growth, reduced body fat, increased immune system and reduction of stress.

Depending on your age and health conditions, past scientific studies showed that Tongkat Ali will take into effect between several hours to several days. However, in most cases, you can feel the difference in energy levels after 12 to 24 hours.

For long-term effect of Tongkat Ali, daily consumption of 4 weeks to 12 weeks will bring significant improvements.

For young active adults below 40, improvement in sexual libido can be felt a couple of hours after the first dosage of Tongkat Ali.

If you are diagnosed with Androgen deficiency or looking to improve Erectile Dysfunction, long term consumption may be required.

Tongkat Ali is widely reported as a natural viagra by the media such as ABCNews, Fox News and even Reuters.

Scientists have found evidence that Tongkat Ali is a proven alternative to improve men’s libido through the activation of increased testosterone in the body.

Despite initial findings, it had attracted more research specialists to investigate whether Tongkat Ali can improve erectile dysfunction.

A study published in the Journal of Evidence-Based Complementary and Alternative Medicine showed improvement in erection hardness and time, sperm motility and concentration amongst others.

Tests on daily consumption of 300mg of Tongkat Ali on 26 test subjects (with Placebo group) aged 40-64 years of age showed sufficient evidence that Tongkat Ali can be used safely as a natural viagra.

Tongkat Ali offers a wide range of scientifically-proven benefits beyond its single-use as natural viagra.
