Nutricost Magnesium Oxide 750 mg
Brand: Nutricost · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product provides 750 mg of magnesium oxide per serving, but data for magnesium oxide specifically is not available. Our assessment focuses on the calcium content listed in the data. Calcium is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural and signaling mineral. It supports bone density and mineral deposition, and it helps your muscles relax and nerves signal properly [NIH ODS]. This mechanism is critical for your daily function, from movement to heart rhythm regulation.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories [FDA data]. For calcium specifically, 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 [NIH ODS]. You should also know that 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 recommendation on this product. Because of the potential risks from high calcium intake, do not exceed the recommended daily intake without medical supervision. If you take any medications listed in the interactions, separate calcium intake by at least two hours. Consult your healthcare provider before starting this supplement [NIH ODS].
