Our assessment
The evidence shows that calcium is a critical mineral for bone health and muscle function. For a product like Nature Made Magnesium 250 mg, the data on calcium helps us understand how minerals work together in your body, though this specific product contains magnesium, not calcium. The data confirms that calcium supports bone density and neuromuscular signaling [NIH ODS].
How it works
Think of calcium as a building block and messenger — it helps deposit minerals into your bone matrix for strength and allows your muscles to relax and nerves to communicate properly after contracting [NIH ODS]. This is why balancing calcium with magnesium is important for your overall mineral health.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms. Some research suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS] [FDA data].
Our recommendation
Start by getting your calcium from food sources first. If you take a magnesium supplement like Nature Made Magnesium 250 mg, be aware that calcium can reduce absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take calcium and magnesium supplements at separate times from these medications [NIH ODS].
