How it works
Think of calcium as a key building block for your skeleton. It supports bone mineralization and density, and it also helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for this product category. You should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer.
