Our assessment
The evidence shows that calcium is a critical mineral for bone health, but it requires careful management. For most adults, getting calcium from food is preferable to supplements, as high-dose supplementation carries real risks [NIH ODS].
How it works
Think of calcium as a structural building block — it directly supports bone density and mineralization, and it is essential for neuromuscular relaxation and nerve signaling [NIH ODS]. Your body prioritizes blood calcium levels over bone stores, so if you don't get enough from your diet, it will pull calcium from your skeleton.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, with specific side effects for calcium including constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms at high blood levels [FDA data] [NIH ODS]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are not getting enough calcium from food, consider a supplement, but do not exceed 1,000–1,200 mg total daily intake from all sources. Take calcium supplements with food and separate them from thyroid medication or antibiotics by at least 2 hours [NIH ODS]. Always discuss with your doctor before starting, especially if you have a history of kidney stones or heart conditions.
