How it works
Think of calcium as a structural building block for your bones and a signal regulator for your nerves and muscles. It supports bone mineralization and density, and it plays a role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for all products in this category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer.
