N,N-Dimethylglycine (DMG) is a compound built from the amino acid glycine. The body uses it as a methyl donor in one-carbon metabolism, a set of chemical pathways that help process certain nutrients.
Manufacturers sell DMG capsules and tablets for energy, mental sharpness, and immune support. These claims lean on its theoretical role in metabolism. Solid human research and clinical proof remain scarce.
People typically take DMG with meals. Label directions vary widely. Common suggestions fall between 100 and 300 mg per day, a range that lacks strong clinical backing.
Safety information is thin. DMG may lower the seizure threshold in susceptible people. Its effects during pregnancy or breastfeeding are not known. Speak with a healthcare provider before you start taking it.
