Less well-studied than other minerals but consistent signal for bone health and hormone support.

Studied, labeled, or reported-use context: 3-10 mg/day — OTC; not individualized guidance.

What the evidence says

Less well-studied than other minerals but consistent signal for bone health and hormone support. Some evidence for reduced inflammation and arthritis symptoms.

Mechanism

Bone metabolism; steroid hormone regulation (free testosterone/estradiol); calcium/magnesium/vitamin D utilization

Studied, labeled, or reported dose & route

3-10 mg/day

This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
