Our assessment
Our assessment: This product contains calcium, a mineral essential for bone health and muscle function. However, the evidence shows that high calcium intakes from supplements may carry risks, including a potential increase in heart disease and prostate cancer [NIH ODS]. You should carefully evaluate your total calcium intake from all sources before adding this supplement.
How it works
Think of calcium as a structural builder for your bones and a signal conductor for your nerves and muscles. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. This makes it critical for daily function, but your body tightly regulates calcium levels, so balance is key.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, though specific report counts for this product are not available. Data for calcium itself shows that very high levels can cause poor muscle tone, constipation, nausea, weight loss, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Additionally, calcium can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Data not available for a specific dose recommendation for this product. However, you should assess your daily calcium intake from food and other supplements to avoid exceeding safe levels. If you take prescription medications, consult your pharmacist or doctor about potential interactions before starting this supplement [NIH ODS].
