NOW Magnesium Malate 1000 mg
Brand: NOW · Form: TABLET [E0155]
Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. However, the data provided is for calcium, not magnesium malate specifically. For calcium, the NIH ODS confirms its role in bone mineralization and neuromuscular relaxation [NIH ODS]. You should not assume this product’s benefits are identical to those of calcium supplements, as the ingredient label lists a magnesium compound.
How it works
If you are using this product for the calcium it contains, think of calcium as a structural builder — it supports bone density and mineral deposition, and helps your muscles relax and nerves signal properly [NIH ODS]. However, the primary ingredient in this product is magnesium malate, and data on how magnesium malate specifically works is not available in the provided information.
Safety profile
The FDA adverse event database shows a total of 592,059 reports across all supplements, but specific side effect counts for this product are not available. For calcium specifically, the NIH ODS notes that high levels can cause nausea, constipation, weight loss, and abnormal heart rhythms [NIH ODS]. Calcium may also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Side effect data for magnesium malate is not available.
Our recommendation
We recommend caution. Data for this specific product (NOW Magnesium Malate) is not available, so you cannot rely on the calcium data provided here to make a decision. If you are taking any prescription medications, especially antibiotics or thyroid medication, check with your pharmacist before use. Start with a low dose and monitor for any digestive upset. For personalized advice, consult your healthcare provider.
