Our assessment
The evidence shows that MegaFood Magnesium is not the primary concern here; the data provided refers to calcium. Based on the available information, calcium supplements can be effective for bone health, but you must be careful with dosing. The data highlights that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Our assessment is that you should focus on getting your calcium from food first and consult a doctor before starting a supplement.
How it works
Think of calcium as a structural builder for your bones. It supports bone density and mineral deposition, which is critical for preventing fractures as you age [NIH ODS]. It also acts as a neuromuscular relaxant, supporting muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for this ingredient category. The data warns that high levels of calcium in your 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for a specific dosage for MegaFood Magnesium. Given the risks associated with high calcium intake, do not exceed the general daily recommendation of 1,000–1,200 mg from all sources unless directed by your physician [NIH ODS]. Take calcium supplements with food to improve absorption, and separate them from any medications listed in the interactions by at least two hours [NIH ODS].
