Our assessment
The evidence shows that calcium is a critical mineral for bone health, but it must be approached with care. For most adults, the goal should be to meet the Recommended Dietary Allowance (RDA) through food first, with supplements used only when dietary intake falls short. High calcium intakes are not without risks, and more is not better [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It works by supporting bone density and mineral deposition. It also plays a key role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
Data not available for specific side effects of this product. However, for the ingredient calcium, FDA has received 592059 total adverse event reports across all supplements. Some research suggests that high calcium 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 [FDA data] [NIH ODS].
Our recommendation
Do not exceed the RDA for calcium without medical supervision. If you take calcium, be aware it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take calcium at a different time of day from these medications [NIH ODS]. Because this specific product is labeled as magnesium glycinate but the data provided is for calcium, please consult with your pharmacist or doctor to confirm you have the correct supplement for your needs.
