Our assessment
The evidence shows that calcium is essential for your bone health, but the data also reveals important safety considerations you need to know. The FDA has received a total of 592,059 adverse event reports related to this product category, and while many are mild, the risks at high intakes are serious [FDA data].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone density and mineral deposition through a process called bone mineralization. Additionally, calcium helps your muscles relax and supports nerve signaling — a process known as neuromuscular relaxation [NIH ODS].
Safety profile
Data not available for specific side effect report counts for this product. However, high calcium intakes are linked to serious risks. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium 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].
Our recommendation
Start by getting your calcium from food sources when possible. If you need a supplement, be cautious with dosing to avoid high blood levels. Also, be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take calcium at a different time from these medications [NIH ODS].
