I feel like this needs its own thread. In 7 days with Boron supplementation, free testosterone had jumped an average 28%.






After only 1 week of boron supplementation of 6 mg/d, a further study by Naghii et al20 of healthy males (n = 8) found (1) a significant increase in free testosterone, which rose from an average of 11.83 pg/mL to 15.18 pg/mL; and (2) significant decreases in E2, which dropped from 42.33 pg/mL to 25.81 pg/mL. All of the inflammatory biomarkers that were measured also decreased: (1) interleukin (IL) 6, from 1.55 pg/mL to 0.87 pg/mL; (2) high-sensitivity C-reactive protein (hs-CRP) by approximately 50%, a remarkable decrease, from 1460 ng/mL to 795 ng/mL; and (3) tumor necrosis factor α (TNF-α) by approximately 30%, from 12.32 to 9.97 pg/mL. Levels of dihydrotestosterone, cortisol, and vitamin D increased slightly.

The significant decrease in the men’s plasma E2 after 1 week of boron supplementation suggests a higher rate of conversion of total testosterone (T) to free testosterone (FT) in the testosterone metabolic pathway. In support, the ratios of FT/T, T/E2, and FT/E2 were all significantly increased, indicating boron had androgen amplifier effects: (1) FT/T (pg/mL/ng/mL) increased from 3.62 to 4.66; (2) T/E2 (ng/mL) rose from 91.68 to 148; and (3) FT/E2 (ng/mL) from 0.31 to 0.67.

It is well known that approximately 98% of testosterone molecules are bound to proteins in the blood, principally to sex hormone–binding globulin (SHBG), and are not bioavailable because bound hormones cannot exit capillaries.22 Thus, the elevation of unbound free testosterone seen with boron supplementation may have significant beneficial ramifications, particularly in aging men in whom, typically, levels of SHBG increase and levels of FT decrease.
