Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Inform your prescriber about boron supplementation if you are receiving testosterone therapy. Monitor serum total and free testosterone levels periodically. Be aware of signs of androgen excess such as acne, mood changes, or elevated hematocrit.
Why this interaction occurs
Boron has been shown in clinical studies to increase free testosterone levels within one week of supplementation by reducing sex hormone-binding globulin (SHBG). When combined with exogenous testosterone, this can lead to elevated free androgen levels and enhanced androgenic side effects.
Evidence
Evidence level: moderate.
