What this supplement is for

  • Marketed for cognitive benefit based on a single small RCT and rodent data.
  • Per dollar, glycinate covers magnesium adequacy more efficiently for non-cognitive use.

What to look for in a product

  • Preferred third-party verification: Third-party tested (COA).
  • Common contamination risks: Mislabeling / identity.
  • Identity: Magtein is the patented, studied form. Note: per gram, this delivers far less elemental magnesium than glycinate or citrate.
