Our assessment

For the specific product, The Vitamin Shoppe Magnesium Glycinate 400 mg, data on its exact formulation, bioavailability, and clinical efficacy is limited.

How it works
Think of magnesium as a critical co-factor — it helps your muscles relax, supports nerve function, and contributes to energy production. The glycinate form binds magnesium to the amino acid glycine, which is often better tolerated by the digestive system and may promote a calming effect on the brain [NIH ODS]. For this specific product, no additional studies from the provided list are available to confirm its unique mechanism.

Our recommendation
Start with a lower dose, such as 200 mg, to assess your tolerance. Take it with food to minimize stomach upset. Choose magnesium glycinate if you have a sensitive stomach or are looking for a calming effect [NIH ODS]. For this specific product, we recommend checking a third-party seal (like USP or NSF) to ensure quality, though data on this specific batch is not available.
