Our assessment
The evidence shows that calcium is essential for bone health, but the data does not confirm the specific benefits of this product beyond what is known about the mineral itself. You should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Because the brand and label information for this product is not available, we cannot verify its quality or formulation.
How it works
Think of calcium as a structural foundation for your bones. It supports bone density and mineral deposition, and also plays a role in muscle relaxation and nerve signaling [NIH ODS]. Without adequate calcium, your body may leach it from your bones, which can weaken them over time.
Safety profile
The FDA has received a total of 592,059 adverse event reports for products containing this ingredient, though this number includes all reports across many formulations [FDA data]. Specific side effects from high calcium levels include 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
Start by assessing your dietary calcium intake from food sources first. If you need a supplement, choose one with a known brand and verified label. Be cautious about high doses, and discuss any potential interactions with your doctor, especially if you take prescription medications [NIH ODS].
