Our assessment
The evidence shows that while calcium is essential for bone health, you should approach supplementation with caution. Our assessment: for most adults, getting calcium from food is safer than from supplements, as high intakes may carry cardiovascular risks [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a signal regulator for your nerves. It supports bone density and mineralization, while also helping your muscles relax and your nerves transmit signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, 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]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you prioritize dietary sources of calcium before turning to supplements. If you do use a supplement, be aware of the potential for serious side effects at high doses and check for interactions with your medications [NIH ODS].
