NOW Magnesium Malate 1000 mg
Brand: NOW · Form: TABLET [E0155]
Our assessment
The evidence shows that NOW Magnesium Malate 1000 mg is a supplement containing the mineral calcium. Our assessment is that while calcium is essential for bone health, the specific benefits and risks of this product depend on your individual dietary intake and health status. You should not take this product if you are already getting enough calcium from your diet or other supplements, as excess intake carries real risks [NIH ODS].
How it works
Think of calcium as a structural builder and signal manager. It supports bone density and mineral deposition, which is critical for maintaining strong bones. Additionally, it supports muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
The FDA received 592,059 total adverse event reports across all supplement categories, though data for this specific product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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].
Our recommendation
Our recommendation is to be cautious. Do not take this supplement unless you have confirmed a calcium deficiency with your doctor. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. If you take any of these medications, you must separate your doses by at least 2 hours [NIH ODS].
