Our assessment
The evidence shows you should be cautious about taking calcium supplements without a clear medical reason. While calcium is essential for bone health, the data highlights significant risks at high intake levels [NIH ODS].
How it works
Think of calcium as a key structural mineral — it supports bone density and mineralization, and also helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. Specific to calcium, high intakes might increase the risk of heart disease and prostate cancer. 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].
Our recommendation
Do not take calcium supplements unless your doctor confirms you need them. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
