Our assessment
Our assessment: The evidence shows that this product provides calcium, a mineral essential for bone health. However, you should be aware of the potential risks and interactions associated with calcium supplementation. The data supports that calcium plays a key role in bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural builder and signal messenger for your body. It supports bone density and mineral deposition, and it is also critical for muscle relaxation and nerve signaling [NIH ODS].
Safety profile
The 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 [NIH ODS]. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: You should not take this supplement without first consulting your doctor, especially if you take any of the medications listed above. Because the product label does not specify the exact amount of calcium per serving, it is impossible to assess your dosage. Data not available for the specific dose in this product. Be aware of the serious risks associated with high calcium intake and monitor for symptoms of toxicity [NIH ODS] [FDA data].
