PureFormulas Magnesium Glycinate
Brand: PureFormulas · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the specific product you asked about — PureFormulas Magnesium Glycinate — contains calcium as an ingredient. Data for this exact product is limited, so we must rely on the general profile of calcium supplements. Our assessment: calcium is effective for supporting bone density, but you need to be aware of significant safety considerations before taking it [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. This means it helps your bones stay strong and your muscles function properly.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high 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 [NIH ODS] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you do not start this supplement without first discussing it with your healthcare provider. Because calcium carries risks of heart disease and serious side effects at high levels, and because it interacts with many common medications, you need personalized guidance [NIH ODS]. If you are considering calcium for bone health, ask your doctor to check your current calcium levels and review any medications you take before starting.
