PureFormulas Calcium + Magnesium
Brand: PureFormulas · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that calcium is essential for bone health, but the risks of supplementation require careful consideration. For most adults, meeting calcium needs through diet is preferable to supplements. PureFormulas Calcium + Magnesium provides a combination that may support bone mineralization and nerve signaling, but the data on high-dose calcium supplementation raises important safety concerns [NIH ODS].
How it works
Think of calcium as the building block for your bones. It supports bone mineralization and density, and it plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Magnesium often works alongside calcium to support muscle function, though specific data for this combination product is limited to the individual ingredients.
Safety profile
FDA received 592,059 total adverse event reports for this product category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels 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
Start by evaluating your dietary calcium intake. The data does not provide a specific RDA for this product, so consult your healthcare provider before starting. Be aware that calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you choose to supplement, use the lowest effective dose and monitor for side effects. Data on the exact dosage for this specific product is not available.
