    Ingredient Explained: Tongkat Ali

    The supplement roundabout is a very real phenomenon, where compounds that were popular years ago slowly make their way back into the mainstream after a bit of a hiatus -- with Tonkat Ali being a prime example.

    But given what it does in the human body, you have to wonder why it ever went away in the first place.

    Step 1: What is it?

    Togkat Ali (also known as “Eurycoma longifolia” in scientific circles) is a plant found growing in the Malaysian rainforest. 

    It has been used for centuries across indonesia in traditional medicine practices to increase erectile strength, treat erectile dysfunction, improve libido, and enhance sexual performance -- which is why it is colloquially known as “Malaysian Viagra.”

    However, this is not where its benefits stop.

    Step 2: What does it do?

    Tongkat Ali is a unique plant that contains several bioactive compounds known as “Quassinoids.” These compounds interact with the body in a number of ways, which can provide several unique benefits.

    As I have already alluded to, Tongkat Ali has been shown have a profound effect on libido and sexual function, with studies even suggesting it is a potent treatment for erectile dysfunction [1]. Interestingly, it also appears to increase sperm production and motility, suggesting it may offer a way to improve male fertility [2].

    Taking more of a “fitness perspective” on the matter, Tongkat Ali has also been shown to cause an increase in testosterone levels (albeit in older men) [3]. This suggests that it may offer a viable method to prevent age-related declines in testosterone, and may even provide a potent natural testosterone booster in male adults.

    Burling on this in more detail, a recent study demonstrated that individuals who supplement with Togkat Ali while undergoing a resistance training program see more muscle growth than those who complete the same program without supplementing with the compound [4]. This suggests that it may also promote increases in muscle growth, making it a potential addition to any mass gaining supplement routine.

    Finally, Tongak Ali also appears to have a positive effect on mood and emotional wellbeing. Its supplementation has been shown to reduce stress, lower cortisol levels, reduce anger, and increase happiness [5].

    While this may not sound like a big deal, there is some evidence to suggest that life stress can negatively impact training adaptations related to strength and size [6]. With this in mind, reducing stress may be a viable way to enhance recovery, and by extension, improve gains.

    Step 3: How do I take it?

    As with most herbal supplements, there are no clear guidelines regarding the optimal dosage of Tongkat Ali. However, much of the research  discussed in this article used dosages between 200 and 500 mg.

    Additionally, there is some evidence suggesting that up to 1200 milligrams per day can be tolerated by humans -- although there is no need to take this much based on the current literature.

    As such, we would recommend taking between 300 and 500 mg per day to maximize training outcomes.

    Also please note that there is yet to be any research looking at Tongkat Ali supplementation in pregnant or breastfeeding women. As such, it is unclear if it is safe for consumption during pregnancy or while breastfeeding  (and we would suggest avoiding it).

    Step 4: What are the top products?

    There are a few things we think are important when looking to buy Tongkat Ali.

    Firstly, don't get caught out paying too much. We would suggest looking for brands that have minimal advertising (which tends to cost a lot) and only provide scientific evidence to support their use. That is how you get the best value Tongkat Ali on the market.  

    Next, make sure the amount of Tongkat Ali is clearly defined on the label. Many supplements use proprietary blends that are ultimately a way for them to provide less of the active ingredient. In line with the recommendations above, you want a supplement that has at least 200mg of Tongkat Ali per serve.

    Lastly, have a look at the online reviews for the supplement. If other people have had a good experience, then you probably will as well.

  • 4 Ingredients Proven to Boost Your Testosterone Levels


    When men reach the age of 30, their testosterone levels peak and from there, these levels slowly begin to decline each year. The average guy loses 1% of his total testosterone each year. If you have an unhealthy lifestyle, this number may be higher. If you're pursuing weight lifting and eating a balanced diet, this number may be lower. One thing that every man can do is supplement. Supplements are a safe way to increase natural testosterone levels but not all ingredients work. Let's take a look at the top 4 scientifically proven testosterone boosters.


    1. Tongkat Ali


    Eurycoma Longifolia Jack is most commonly referred to as Tongkat Ali and sometimes sold as Malaysian Ginseng. Regardless of the name, this herbal remedy is from the rain forests of Malaysia and it's been used in traditional medicinal practices for hundreds, if not thousands, of years. At one time, it was used as an overall health aid. Once it was brought into the West, it was used primarily for increasing sex drive and libido. Eventually researchers discovered it had a positive impact on men's testosterone levels. (1)


    How much to take:

    • Extract form: 200 to 300mg (Based on 100:1 extract)


    1. Ashwagandha


    Another herbal remedy from ancient times, Ashwagandha has played a part in primarily Indian alternative medicine for many years. At one time, Ashwagandha was used as an overall health and well-being supplement. Modern medicine has discovered that Ashwagandha has many benefits outside of the fitness world including being an anti-inflammatory and a cancer fighter.


    When it comes to men's health, Ashwagandha has been shown to improve the quality of your sleep, lower cortisol (catabolic hormone) levels, and increase testosterone (anabolic hormone) levels. (2)


    How much to take:

    • Extract form: 300 to 400 mg


    1. Vitamin D


    The same essential vitamin found in dairy products is, indeed, a testosterone booster. Vitamin D has been shown time and time again in scientific studies to be one of the most effective ways to support testosterone production. Ideally, you're getting in whole food-based Vitamin D and spending some time in the sun. However, supplementing with a high quality Vitamin D3 product is also an excellent way to hit your daily recommended serving. (3)


    How much to take:

    • Vitamin D3 – One serving per day with a meal


    1. ZMA


    ZMA has been a staple in the bodybuilding world since that ground-breaking study was released to the public. Used primarily for sports recovery and to improve healthy sleeping patterns, ZMA is also a highly effective testosterone booster. ZMA is made up of Zinc, Magnesium, and Vitamin B6. On their own, these ingredients have ALL been shown to have a positive response on your testosterone levels. Together, they are unstoppable. Studies show that when men supplement with ZMA, they see a boost in testosterone as well as growth hormone. (4-6)


    How much to take:

    • One serving 30 minutes before bed on an empty stomach.




    Whether you are approaching the big 3-0 or you passed it long ago, it's never too late to start a healthy regimen to increase the thing that makes you a man: testosterone. Healthy testosterone levels result in an improved quality of life. If you want to naturally and safely boost your testosterone production, these four supplements are the best of the best.
