Our assessment
The evidence shows that while calcium is essential for your health, supplementation requires careful consideration. For most adults, getting calcium from food is preferable, and you should only supplement if you cannot meet the RDA through diet alone. The data on high-dose supplementation includes notable safety signals that you need to understand before starting.
How it works
Think of calcium as a building block for your skeleton and a signaling molecule for your nerves and muscles. Its primary roles are bone mineralization, which supports bone density and mineral deposition, and neuromuscular relaxation, which supports muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for this product category. Specific side effects from high calcium intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [FDA data]. High levels of calcium in the blood and urine can also cause poor muscle tone, poor kidney function, low phosphate levels, and a high risk of death from heart disease [NIH ODS]. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Additionally, calcium supplements can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to prioritize dietary sources of calcium before considering supplementation. If you take a calcium supplement, do not exceed the RDA unless specifically directed by your physician. Be aware of the potential interactions with common medications and monitor for side effects like constipation or nausea [NIH ODS] [FDA data]. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before use. Data not available on optimal dosing for this specific product.
