Our assessment
The evidence shows that this product contains one active ingredient: Calcium. Our assessment: Calcium is a well-studied mineral, but the benefits depend entirely on your current intake and health status. Data not available for specific magnesium content or other ingredients in this product.
How it works
Think of calcium as a structural and signaling mineral. It supports bone mineralization and density, and it helps regulate neuromuscular relaxation and nerve signaling [NIH ODS]. For you, this means calcium plays a role in keeping your bones strong and your muscles functioning properly.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels 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 bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your total daily calcium intake from food and other supplements. Do not exceed 2,500 mg total per day from all sources. If you take thyroid medication or antibiotics, separate calcium by at least 2 hours [NIH ODS]. We recommend getting a blood test to check your calcium levels before routine supplementation.
