Our assessment
Our assessment: Magnesium is a vital mineral for hundreds of bodily processes, and The Vitamin Shoppe Magnesium Glycinate 400 mg provides a well-absorbed form. The evidence shows that magnesium glycinate is often recommended for its high bioavailability and gentle effect on the stomach. The RDA for magnesium is 400–420 mg for men and 310–320 mg for women [NIH ODS].
How it works
Think of magnesium as a calming cofactor — it helps regulate muscle and nerve function, supports a steady heartbeat, and plays a role in bone health and protein synthesis [NIH ODS]. The glycinate form combines magnesium with the amino acid glycine, which may promote relaxation and better sleep quality. Your body uses this mineral in over 300 enzyme systems [NIH ODS].
Safety profile
Data not available on adverse event reports specifically for this product from the provided FDA data. The Tolerable Upper Intake Level from supplements is 350 mg per day for elemental magnesium [NIH ODS]. High doses may cause diarrhea and abdominal cramping [NIH ODS]. Always check the elemental magnesium content in your supplement.
Our recommendation
Start with one capsule daily to assess your tolerance. Because this provides 400 mg of elemental magnesium, it is above the upper intake level for supplemental magnesium. You may consider taking half a dose or using it only under the guidance of a healthcare professional [NIH ODS].
