Our assessment
Our assessment: The evidence shows that calcium is a critical mineral for your bone health, but it requires careful dosing and timing. The data confirms that calcium supports bone density and neuromuscular relaxation [NIH ODS]. However, you need to be aware of the risks: some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also helps your muscles relax and your nerves signal properly [NIH ODS]. To get the most benefit, you must be mindful of timing: calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Safety profile
Safety data is critical here. The FDA received a total of 592,059 adverse event reports across all supplement categories. 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]. Data not available for the specific number of adverse event reports for calcium alone.
Our recommendation
Our recommendation: Do not exceed the established upper intake levels. Take calcium supplements at least two hours apart from any medications listed above to prevent absorption issues [NIH ODS]. If you have a history of heart disease, kidney stones, or prostate cancer, you should discuss calcium supplementation with your doctor before starting [NIH ODS].
