NOW Magnesium Citrate Pure Powder
Brand: NOW · Form: POWDER [E0162] On Market
Our assessment
The evidence shows that NOW Magnesium Citrate Pure Powder is a well-absorbed form of magnesium, but it is important to understand that this product contains magnesium, not calcium. The data provided for calcium does not apply here. Our assessment is that magnesium citrate is a reliable choice for supporting muscle relaxation and overall mineral balance, though you must follow the label dosing carefully to avoid digestive upset.
How it works
Think of magnesium as a natural relaxant for your muscles and nervous system. It helps regulate nerve signals and supports the relaxation phase of muscle contraction. Magnesium citrate, specifically, is bound to citric acid, which enhances absorption in your digestive tract. The NIH ODS data on calcium is not relevant to this product, as the ingredient is magnesium [NIH ODS].
Safety profile
For this specific product, side effect data is not available in the provided FDA data set. The total adverse event reports across all supplements in the FDA database is 592,059, but this number is not specific to NOW Magnesium Citrate Pure Powder. Do not confuse this with calcium side effects; the data provided for calcium is for a different mineral [FDA data].
Our recommendation
Start with the serving size listed on the label. Mix the powder fully into water or juice to reduce the risk of digestive discomfort. If you experience loose stools, reduce your dose. Always separate this supplement from prescription medications by at least two hours to avoid absorption issues, as minerals can interact with certain drugs [NIH ODS].
