Hormonal

Chronic calcium deficiency resulting from inadequate intake or poor absorption causes reduced bone mass and osteoporosis by triggering parathyroid hormone (PTH)-mediated bone resorption.

Ensure you get enough calcium from food sources like dairy or fortified foods, especially if you are postmenopausal or an adolescent, because chronic low intake triggers hormonal processes that break down bone. If you cannot meet intake goals, consider calcium-fortified foods or supplements, but be aware that absorption varies and may not fully prevent bone loss in all groups.

GoodSupportsHIGH confidence
Chronic Ca deficiency resulting from inadequate intake or poor intestinal absorption is one of several important causes of reduced bone mass and osteoporosis.

Why this rating

Based on a review of multiple intervention and cross-sectional studies, though some debate exists on the magnitude of effect on peak bone mass.
