Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. Our assessment is that while calcium plays a key role in supporting bone density and muscle function, you should be aware of the specific risks and interactions associated with supplementation [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and helps with neuromuscular relaxation, meaning it assists your muscles in relaxing and your nerves in sending signals properly [NIH ODS].
Safety profile
Data not available for this specific product's adverse events. In the broader FDA database, there are 592,059 total adverse event reports for all products. 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
Consult your healthcare provider before taking this supplement, especially if you take medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, as calcium can reduce their absorption [NIH ODS]. Monitor your total calcium intake from all sources to avoid exceeding safe levels.
