Our assessment
The evidence shows that calcium is a critical mineral for your bone health, but it comes with important safety considerations. For a general audience, the data confirms that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural builder — it supports bone density and mineral deposition, keeping your skeleton strong. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the 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].
Our recommendation
Data not available for a specific dosage recommendation for this product. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Take calcium supplements at least two hours apart from these medications. Always consult your healthcare provider before starting a new supplement.
