TMG (Trimethylglycine) is known to facilitate methylation processes. Methylation is a normal biological process that is critical for DNA repair, liver detoxification mechanisms, lipid metabolism, and the production of SAMe. It is also an important step in the conversion of homocysteine, a damaging amino acid, into a more friendly amino acid, methionine. Supplementation with TMG has been shown in clinical and non-clinical studies to support healthy homocysteine levels already within normal range.
