NOW Iron 18 mg

Our assessment

The evidence shows that calcium is a fundamental mineral for bone health, but it is not without important considerations. While calcium supports bone density and neuromuscular function, the data indicates that excessive intake can pose health risks [NIH ODS]. For this specific product, NOW Iron 18 mg, the primary ingredient is iron, not calcium. Therefore, the data provided on calcium does not directly apply to this supplement. Our assessment is that we cannot evaluate this product based on the available data, as the ingredient information is missing for NOW Iron 18 mg.

How it works

Calcium acts as a master regulator for your body's structural framework, supporting bone mineralization and density. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS]. However, since this product is NOW Iron 18 mg, the mechanism of calcium is not relevant here. Data on how iron works is not available in the provided information.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available.

For NOW Iron 18 mg, side effects from the provided FDA data are not available.
