Regular supplementation of B6 (Pyridoxine) has been found to directly boost testosterone levels by stimulating other androgens. Simultaneously, research indicates they also reduce the build-up of the female hormone estrogen, which works against testosterone.
Studies have found that being deficient in B6 will result in a sharp decrease in your testosterone levels [10]. Further research suggests that high levels of B6 can help inhibit estrogen levels by up to 30% [11]. All of this helps optimise testosterone levels within your body.
