Our assessment
Our assessment: The evidence shows that calcium is a critical mineral for your bone health, but you need to be careful with dosing.

For calcium specifically, there are 592,059 total adverse event reports across all supplements in the FDA database [FDA data].
How it works
Think of calcium as a structural builder for your body. It supports bone density and mineral deposition, which is essential for 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
You should be aware that some research suggests high calcium 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Because the specific ingredient data for this product is not available, we cannot verify its contents. For calcium, you should not exceed the recommended daily intake without medical supervision. If you take any of the medications listed above, take calcium at a different time of day. Always consult your doctor before starting a new supplement [NIH ODS].
