Our assessment
The evidence shows that this product contains calcium, not magnesium gluconate as the name suggests. Our assessment is that you should be aware of this labeling discrepancy before use. For calcium, the data confirms it plays a role in bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a signaling molecule for your nerves and muscles. It supports bone density and mineral deposition, and helps with muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine calcium levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Given the label discrepancy, we recommend verifying the actual ingredient with the manufacturer before use. If you are seeking a calcium supplement, be aware of the potential risks and drug interactions. Do not exceed recommended intakes without medical supervision [NIH ODS].
