Tongkat Ali And Testosterone: What The Research Shows

By the Alpha Erec Wellness Desk · · 6 min read

In Short

Tongkat Ali, also known as Longjack, is a traditional botanical with one of the more substantial research bases among natural testosterone-support ingredients.

A frequently cited 2013 study found a notable association between Tongkat Ali use and increased free testosterone, worth understanding in full context.

What the 2013 study found

A study published in the Journal of the International Society of Sports Nutrition found that men taking Tongkat Ali extract for 4 weeks saw a 37% increase in free testosterone levels. This is a frequently cited finding in the men's vitality supplement category.

Being precise about what this means

Important context: a single study, even a well-cited one, is not the same as a robust, replicated evidence base. The 37% figure comes from one specific trial with its own population, dose, and duration — results in a different study population, at a different dose, could vary.

Why the traditional use history matters too

Beyond the specific study, Tongkat Ali has a long history of traditional use in Southeast Asian herbal medicine specifically for male vitality, which is part of why it has attracted more modern research attention than many other botanicals in this category.

Why the dose matters

The 2013 study used a specific, standardized extract at a defined dose. Since Alpha Erec does not disclose its exact Tongkat Ali amount per gummy, direct comparison to the study's dose is not possible.

Applying this to Alpha Erec

Tongkat Ali is one of Alpha Erec's eight ingredients, and it is arguably the most specifically cited ingredient in the formula for testosterone-linked support.
