What the Science Says

Calcium is the most abundant mineral in the human body, essential for building and maintaining strong bones and teeth. The provided research highlights that calcium deficiency is highly prevalent — particularly among female collegiate dancers, where 67–97% fell short of recommended intake levels. Calcium also plays roles in muscle contraction, nerve signaling, and vascular function, though the studies provided do not directly test calcium supplementation outcomes.

What It Doesn't Do

No evidence from these studies that calcium supplements alone build muscle. No proof it prevents fractures in healthy adults based on the provided data. Calcium supplements are not a substitute for adequate total energy intake. Taking more than you need won't make your bones stronger.

Evidence-Based Benefits

Most female collegiate dancers fall well short of recommended daily calcium intake from food alone.

Absorption & Bioavailability

Unknown from provided studies — no pharmacokinetic or absorption data was included in the provided papers.

Red Flags to Watch For

Most provided papers are not about calcium supplementation at all — evidence base here is extremely thin
Calcium deficiency is common even among supplement users, suggesting supplements often don't fully correct dietary shortfalls
High-dose calcium supplements have been associated with cardiovascular concerns in other literature, though this was not addressed in the provided studies
Only 4 patients in the bone mineral density study received calcium supplementation — far too few to draw conclusions
