The Vitamin Shoppe Magnesium Glycinate 400 mg
Brand: The Vitamin Shoppe · Form: TABLET [E0155]
Our assessment
The evidence shows that magnesium is essential for over 300 biochemical reactions in your body, and magnesium glycinate is a well-absorbed form. The product provides 400 mg of magnesium glycinate, but the precise amount of elemental magnesium per serving is not specified in the data provided. Without this number, we cannot confirm if this meets the RDA of 310–420 mg for most adults [NIH ODS].
How it works
Think of magnesium as a calming mineral — it helps regulate nerve function, muscle contractions, and blood pressure. The glycinate form is bound to the amino acid glycine, which may promote relaxation and improve sleep quality by supporting the body's stress response system [NIH ODS].
Safety profile
Data not available for specific side effects or adverse event report counts for this product. In general, high doses of magnesium from supplements can cause diarrhea, cramping, and nausea [NIH ODS]. The FDA data provided does not include specific adverse event reports for magnesium glycinate [FDA data].
Our recommendation
If you choose to take this supplement, start with one serving daily and increase gradually. Look for the elemental magnesium content on the label. For best absorption, take with food. Always consult your doctor before starting, especially if you have kidney issues or take medications [NIH ODS].
