Boron
Boron is a trace element that modulates sex hormone binding globulin, increases free testosterone & estradiol, enhances vitamin D activity, & supports calcium & magnesium retention in bone; evidence suggests benefits for hormonal balance & bone mineral metabolism.
Evidence last reviewed: 04 Apr 2026
The evidence for boron is limited, with studies showing potential benefits in hormonal modulation and bone mineral metabolism. However, the quality of the studies is low, and more research is needed to confirm these effects.
Free testosterone, estradiol, & inflammatory cytokines in healthy menHealthy male volunteers · controlled supplementation studyLow
A controlled study in 8 healthy men found that daily supplementation with 10 mg boron for one week significantly increased free testosterone (11.83 to 15.18 pg/mL), decreased estradiol (42.33 to 25.81 pg/mL), increased dihydrotestosterone, cortisol, & vitamin D, & decreased all three measured inflammatory biomarkers (hsCRP, TNF-α, IL-6).
Calcium & bone mineral metabolism in postmenopausal womenPostmenopausal women · controlled metabolic studyLow
A controlled metabolic study found that boron supplementation (3 mg/day) in postmenopausal women markedly reduced urinary calcium & magnesium excretion & significantly elevated serum 17β-estradiol & testosterone; effects were most pronounced in women consuming low-magnesium diets, suggesting boron potentiates calcium retention & bone-protective hormonal profiles.
