Magnesium glycinate powder, as a third-generation magnesium fortifier, is gentle and non-irritating to the gastrointestinal tract, with a much higher intestinal absorption rate than other magnesium supplements. Magnesium is attached to glycine, an amino acid that inhibits neurotransmitters and has a calming effect. It can be used in products that improve sleep problems, tension, anxiety, and other neurological issues.
