How it works
Think of calcium as a key building block for your bones and a regulator for your nerves and muscles. It supports bone density and mineral deposition, and helps with muscle relaxation and nerve signaling [NIH ODS].
Safety profile
The 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. High levels in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
