Calcium

Menstrual and women's health is the main area connected here, and any felt benefit should be read together with the human evidence base.

The 50.0 score includes research signals from patient or disease contexts. General supplement evidence is not repeated enough, so the C tier remains conservative.

Representative tier calculated from paper evidence that passed the collection audit.
