QUICK ANSWER

Boron Glycinate: Bone · hormones · joint. Trace mineral linked to free testosterone, vitamin D activation, and calcium routing into bone. Standard dose 5 mg, taken in the morning, about $9/month. Evidence rating: moderate evidence.

What is Boron Glycinate?

Boron is an ultra-trace mineral with surprisingly broad effects on hormonal and skeletal health. Modest daily supplementation has been shown to support bone density by improving calcium and magnesium retention, to activate vitamin D, and, in small but consistent studies, to raise free testosterone and DHT while modestly lowering inflammatory markers and SHBG in men. It may also support joint comfort by reducing inflammation in connective tissue. Standard doses range from 3-10 mg daily, well below the 20 mg upper limit. Boron is found in raisins, almonds, avocado, and prunes.

WHY IT MATTERS

Trace mineral linked to free testosterone, vitamin D activation, and calcium routing into bone.
