Supplements for Testosterone Levels

What the Research Shows

Clinical research on supplements for increasing testosterone levels generally shows limited effectiveness for healthy adults. While many products are marketed as boosters, few have strong evidence supporting their use. Fenugreek is one of the few supplements with moderate evidence suggesting it may increase free testosterone and improve libido, though results can vary across different studies. Other common supplements, such as Tribulus terrestris, D-aspartic acid, and Ashwagandha, have weak or conflicting evidence. While some small trials show temporary increases in testosterone or strength, these effects are often inconsistent or not sustained over time. For many other botanical extracts, evidence remains insufficient to conclude they have any meaningful impact on hormone levels. Most current research is limited by small sample sizes, short study durations, and a lack of standardized dosing. Consequently, it is difficult to determine if these supplements provide long-term benefits or if the observed effects are statistically significant for the general population.
