Our assessment
The evidence shows that this product provides calcium, a mineral essential for bone health and muscle function. Our assessment is that calcium is a well-studied supplement, but you must be careful with your total daily intake from all sources, including food and other supplements [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton and a signaling molecule for your nerves and muscles. It supports bone density and mineral deposition, and it helps with neuromuscular relaxation for proper muscle and nerve signaling [NIH ODS].
Safety profile
Data not available for side effects specific to this product. FDA has received a total of 592,059 adverse event reports across all dietary supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels in your blood and urine can cause constipation, nausea, weight loss, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS].
Our recommendation
Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. If you take any of these, separate your calcium dose by at least 2 hours. Do not exceed the Tolerable Upper Intake Level without medical supervision [NIH ODS].
