Tongkat Ali and Testosterone Wellness

By Horsewood Research Team · Reviewed by Dr. Nathan Cole, M.D. · Updated June 2026

Tongkat Ali is a foundational ingredient in Horsewood's formula. Here's why it matters.

What Is Tongkat Ali?

Tongkat Ali (Eurycoma longifolia) is a traditional Southeast Asian botanical extensively studied for its role in men's health.

The Research Behind It

Tongkat Ali has one of the more substantial research bases among botanical testosterone-support ingredients, with studies exploring its role in supporting testosterone levels already within the normal range.

The 100:1 Extract Standard

Concentrated extract ratios like 100:1 are associated with a more potent, standardized dose compared to raw root powder.
