The evidence in words
The verdict
For free testosterone, Boron earns evidence grade C (small effect, mixed consistency) — the evidence is limited or mixed. Via lower SHBG
How it might work
Boron appears to lower sex-hormone-binding globulin (freeing testosterone and estrogen), slow vitamin D breakdown, and influence magnesium and calcium handling and some inflammatory markers.
How to use it
6–10 mg/day. Often stacked with vitamin D and a testosterone-support goal.
Safety & cautions
Safe at these doses; toxicity requires far higher intakes.
Bottom line
A minor, low-cost lever for free testosterone and vitamin D metabolism. Real but small — a supporting act, not a star.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
