Boron is a trace mineral that has received scientific attention for its potential effects on testosterone levels. Several small clinical studies have investigated boron's impact on hormonal status in men. For example, a study published in 2011 in the journal Biological Trace Element Research found that healthy male volunteers who supplemented with 10 mg of boron daily for one week showed a significant increase in free testosterone levels and a decrease in estradiol. Other studies have reported similar short-term hormonal changes, suggesting that boron may play a role in modulating steroid hormones, possibly by influencing the activity of enzymes involved in testosterone metabolism and by reducing inflammation (as measured by CRP levels).

However, the overall scientific evidence remains limited due to small sample sizes, short study durations, and a lack of large-scale, long-term trials. There is insufficient evidence to recommend boron supplementation as a primary treatment for clinically low testosterone, and more research is needed to determine effective dosing, safety, and long-term outcomes. Current support for boron’s use in testosterone management is based on preliminary data and mechanistic plausibility rather than robust clinical trials. There is no strong tradition of its use for this purpose in historical or folk medicine.
