Our assessment
Our assessment: Based on the data provided, this product contains Calcium, not Magnesium. The evidence shows that calcium is essential for bone health and nerve function, but it comes with specific risks you need to understand. Data not available for Magnesium in this analysis.
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization and density, and it helps your muscles relax and your nerves signal properly [NIH ODS]. Think of it as the key building block for your skeleton and a critical messenger for your nervous system.
Safety profile
The FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood 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].
Our recommendation
Check your supplement label carefully — this product lists Calcium, not Magnesium. If you take calcium, be aware it can reduce absorption of bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Take calcium separately from these medications. Do not exceed recommended daily intake without medical supervision. Data not available for a specific dosage recommendation for this product.
