Our assessment
The evidence shows that calcium is a critical mineral for your body, but supplementation requires careful consideration. Our assessment is that you should prioritize getting calcium from food sources first, and only use supplements like this one to fill a specific gap in your diet. The data confirms that calcium supports bone density and muscle relaxation, but high intakes come with notable risks [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It works through bone mineralization to support bone density and mineral deposition. Additionally, it plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though specific counts for calcium alone are not available in the provided data. 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. Some research also suggests high intakes might increase the risk of heart disease and prostate cancer [NIH ODS] [FDA data].
Our recommendation
Start by assessing your dietary intake. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you take any of these, separate your supplement by at least two hours. Do not exceed the recommended dose on the label, and consult your doctor before starting if you have kidney issues or a history of heart disease.
