How it works
Think of calcium as a structural and signaling powerhouse. It supports bone mineralization and density, and it is essential for neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer.
