What Is Tongkat Ali

It's not uncommon to see Tongkat Ali listed as part of the main ingredients formula of popular testosterone boosters and sexual performance supplements.

In this article we intend to explore the different benefits and side effects of Tongkat Ali. Our primary goal is to confirm whether or not this is a scientifically proven active ingredient to boost testosterone.

When you consider testosterone boosters on the marketplace today, a number of them are marketed with ingredients that are claimed to be testosterone improving active ingredients, when in truth, there is no scientific proof behind them.

Our goal is to research and analyze all of the most popular market ingredients so we can validate or debunk their claims about whether or not they really do boost testosterone or not and understand the full scope of benefits and potential side effects that you also get with them. 

Tongkat Ali is also known as Eurycoma Longifolia, Longjack, Tung Saw or Pasak Bumi. Basically it is a natural herb that lives natively in the countries of Southeast Asia including Vietnam, Malaysia, Philippines, and also Indonesia. Occasionally the regional homeowners in these nations describe Tongkat Ali (TA) as Malaysian Ginseng. Some people call it "natural viagra" because of its abilities to help deal with various sexual dysfunctions.

TA has a variety of  active components including eurycomanon, eurycomanol, and also eurycomalacton. These active components have been used to help heal and address different illnesses for quite a very long time, centuries in fact.

Benefits Of Tongkat Ali

Testosterone & Tongkat Ali

In doing our research, our main was to see if there was scientific proof that Tongkat Ali really does increase testosterone. As it turns out, there is actually quite a bit of research done on TA, and what we discovered was that Tongkat Ali has been scientifically proven to increase testosterone levels. It was found to work especially well for guys with lower levels of testosterone.

Among the most compelling studies was this one which was composed of 76 men who were suffering from low testosterone. Each of the men were given 200 mg of Tongkat Ali for one month. The results were even greater than expected. Results showed a typical rise in testosterone levels of over 45%! Also remarkable was that over 90% of the men had the ability to maintain their testosterone levels in the normal range after taking Tongkat Ali and the experiment was over.

In 2013, the Journal Of International Society Of Sports Nutrition performed this peer-reviewed research study which included 62 male participants. In this study, half of the men were provided a sugar pill, and the other half were provided Tongkat Ali. The study lasted 4 weeks, and the study results revealed that the group that took TA showed a rise in testosterone of 37%!  What made this study even more interesting was the fact that not only did the TA group show a rise in testosterone of 37%, but it was also documented that they showed a reduction in their cortisol levels of 16%.

These are just 2 instances of research where the science clearly shows that Tongkat Ali is an effective and also efficient testosterone booster that also comes with some additional valuable and powerful health benefits. In our research journey, we discovered countless more studies that showed the very same or similar results.

Tongkat Ali For Libido

TA gets most of its spotlight attention for its ability to light a fire under your sex drive. This is why it is frequently referred to as "herbal viagra". It has actually been used for centuries for this specific purpose. Not only has it been shown to boost libido but it also has actually been shown to increase erection quality. To sum it up, TA appears to be a great overall sex-related performance enhancer on multiple fronts. (study) (study) (study)

Male Fertility & Tongkat Ali

There is also quite a bit of clinical information that supports the fact that TA can positively affect sperm quality, motility, and volume. There was a randomized double-blind research study of 109 males that were broken up into 2 teams. One team received a sugar pill and the other team was given 300 mg of Tongkat Ali. The study was performed over a six-month time period. The outcomes of the research showed an increased in semen mobility by 44% and also volume by 18%.

Another study had 75 men taking TA on a daily basis, and the results of that study showed improvements in all semen parameters including sperm count and sperm quality. Furthermore, what made this study even more interesting was the fact that these results continued to last even months after the study had ended.

Treating Cancer With Tongkat Ali

A study that was highlighted in the Natural Products Journal showed that the TA extract consists of beta-carboline alkaloids that apparently very potent against breast and lung cancer cells. Researchers involved in this research determined 3 brand-new beta-carboline alkaloids and 19 existing ones that are considered to be very cytotoxic to cancer cells. This means that the properties of these specific alkaloids were shown to be very effective at combating the harmful breast and lung cancer cells.

Reduce Anxiety And Stress With Tongkat Ali

As we've seen in various other research studies, one of the results that include taking TA is that it lowers cortisol. In this 4-week research study, the results showed an 11% reduction in stress, a 15% reduction in confusion, a 12% decrease in anger, and also a 16% decrease in cortisol. This is such a powerful side benefit especially because excess cortisol has so many negative and harmful side effects that come with it, of which, reducing testosterone levels is just one of them.

Muscle Gain & Fat Loss

As a result of it's proven testosterone increasing and cortisol reducing capabilities, you are naturally going to experience an improvement in acquiring more lean muscle mass as well as losing more fat, particularly stubborn stomach fat. A 2002 Malaysian study of males taking just 100 mg of Tongkat Ali for 5 weeks revealed an increase in lean muscle mass of 5% and a substantial reduction in body fat.

Here's the bottom line on Tongkat Ali. This ingredient is the real deal. It definitely increases testosterone, and it's been proven that it is especially good at with men suffering from low levels of testosterone. So just for that benefit alone, it goes on our list of known and proven ingredients to boost T. What's even more compelling are the additional health benefits that go along with it as well. These are awesome and powerful bonus benefits, making this one of our favorite all around supplement ingredients.​

Side Effects Of Tongkat Ali

In looking into Tongkat Ali, we observed that there really just weren't numerous noteworthy negative effects. Absolutely there were no serious negative effects influencing kidney or liver function, etc

Here's some more good news as it relates to side effects. As we went through the studies and the research, we really didn't find any major negative side effects to speak of. Through our journey of discovery, we did find little bits and pieces here and there of some mild and possible side effects that some people may experience on a mildly noticeable level:​

  • Increased body heat
  • Increased aggression
  • Insomnia
  • Restlessness

It's important to note here that these are the exceptions rather than the rule, and when we did happen to find these corner cases of side effects, they were typically highlighted as effects that were more prominently seen at the beginning of taking Tongkat Ali as a new supplement, so if you feel like you're predisposed to any of these side effects to begin with, then you might want to start off with a lower dosage and then gradually go up to the recommended daily dose so you can avoid these potential side effects.

Recommended Dosage

In looking at the research studies conducted and overlaying that to exactly what's on the market, you ought to search for a 200:1 essence permanently strength as well as optimum advantage, as well as the dose level need to remain in the 100 mg - 300 mg variety.

First and foremost, we recommend that you find a good potent Tongkat Ali extract of 200:1. This assures you that you're getting the full power and benefits of TA. In looking at the different studies we analyzed in doing our research, we found that the average dose given was in the 300 mg to 500 mg range.  

Looking at the 200:1 Tongkat Ali extracts that you'll find on the market, most of them are in that same range. You will find a few that are in the 800 mg - 1000 mg range as well.

If TA is the only supplement you're taking to boost testosterone vs. taking a testosterone booster that has multiple ingredients, then we would recommend going with one of the higher dosage products.

If you're looking at just supplementing with Tongkat Ali separately on its own, then we would recommend the following product. It's a 400 mg serving taken twice a day for a total of 800 mg:

Having said that, we believe that you ultimately get more testosterone boosting power and efficiency when you use a test booster that has a variety of T boosting ingredients attacking the problem from all different angles.

Additionally, you might want to consider cycling Tongkat Ali. As with any purpose-driven supplement like this, you don't want your body to build up a tolerance for it, and you want to always maximize the benefits it provides. The best way to do this is to cycle it. In this case, your off cycle should be about 40% of what your "on cycle" was. So if you take it for a month straight, then you should cycle off of it for about 10-12 days, and then you can get back on for another month, and so on.


We learned quite a bit about Tongkat Ali in our research. We confirmed that it is scientifically proven to boost testosterone and that it works especially well in men who are suffering from Low T issues to begin with.

We also learned that it is really effective in dealing with virtually any and all sexual performance issues as well. On top of that, you also get all waterfall effects of having increased testosterone, like more energy, more lean muscle mass, less fat, better heart health and immune system, and the list goes on and on.

​So if you happen to see it on a test booster ingredients list as one of the ingredients, then you're off to a good start. Our general rule of thumb is to look for a testosterone booster that has at least 5 of these proven ingredients so you can attack the issue from a variety of angles and get the greatest benefits and results.

Attack low testosterone levels from as many angles as possible. One of the easiest ways to increase your T is by supplementing with an awesome test booster.
