Can Tongkat Ali increase natural testosterone production?

Updated: Feb 15, 2023

Tongkat Ali, also known as Eurycoma longifolia, is a plant that is commonly used in traditional medicine and is believed to have a variety of health benefits, including the potential to increase testosterone levels. However, the scientific evidence supporting this claim is limited and conflicting.

Studies have shown that Tongkat Ali extract may have an effect on testosterone levels in animals, but these results have not been consistently replicated in human trials. In one Malaysian trial men were given 200mg a day. At the beginning of the trial only 35% of participants had 'normal' testosterone levels, by the end closer to 90% did.

It's important to note that the quality of Tongkat Ali supplements available on the market can vary widely, and the active compounds responsible for any potential benefits are not well-defined. In addition, the dosage used in different studies has varied, making it difficult to compare results.

Overall, while there is some evidence to suggest that Tongkat Ali may have a potential effect on testosterone levels, more research is needed to establish the extent and mechanisms of its effects. Additionally, it is always best to consult a healthcare professional before taking any new supplement, especially if you have any pre-existing medical conditions or are taking medications.

In conclusion, Tongkat Ali may have potential effects on testosterone production, but the current evidence is not conclusive and more research is needed to fully understand its effects and safety profile.
