Our assessment
The evidence shows that calcium is a critical mineral for your health, but the data on supplementation includes important safety considerations. Based on the data provided, calcium supports bone density and nerve signaling [NIH ODS]. However, you should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. FDA has received a total of 592,059 adverse event reports across all supplement categories, though specific report counts for calcium alone are not available in the provided data [FDA data].
How it works
Think of calcium as a master regulator for your bones and muscles. It works through bone mineralization, helping your skeleton maintain density and store minerals properly [NIH ODS]. At the same time, calcium supports neuromuscular relaxation, meaning it helps your muscles relax after contracting and assists with nerve signaling throughout your body [NIH ODS].
Safety profile
Data not available for specific side effect report counts for calcium alone. However, the data shows that high levels of calcium 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Given the potential risks associated with high calcium intake, you should aim to get calcium primarily from food sources rather than supplements. If you do choose a supplement, be cautious about total daily intake and discuss with your healthcare provider, especially if you take any of the medications listed that interact with calcium [NIH ODS]. Monitor for symptoms such as constipation, nausea, or extreme tiredness, and seek medical attention if you experience abnormal heart rhythms or frequent urination [NIH ODS].
