Our assessment
The evidence shows that calcium is a critical mineral for your bone health and muscle function, but the data also highlights important safety considerations. For a general audience, this supplement provides a key nutrient, but you must be aware of the potential risks and medication interactions [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton and a cellular messenger. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, though this number is not specific to this product alone [FDA data]. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. 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 [NIH ODS]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on specific side effect counts for this product is not available.
Our recommendation
If you are considering this supplement, start by assessing your current calcium intake from food. Be cautious with high doses due to the potential risks to heart and kidney health [NIH ODS]. If you take any of the listed medications, take your calcium supplement at a different time of day to avoid reducing their absorption [NIH ODS]. Consult your healthcare provider to determine the right dosage for you.
