Our assessment
The evidence shows that calcium is a critical mineral for your bone health, but the risks of supplementation require careful consideration. Our assessment: you should prioritize getting calcium from food sources and only use supplements if your healthcare provider confirms you cannot meet your needs through diet alone [NIH ODS].
How it works
Think of calcium as the structural foundation for your bones and a key player in your nervous system. It supports bone density through mineralization and helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all products in its database. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Extremely high levels in your 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] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Do not start calcium supplements without a confirmed dietary need. Work with your doctor to assess your total calcium intake from food first. If you do supplement, take it with food and separate it from any medications listed above by at least two hours [NIH ODS].
