DMG, or dimethylglycine, is a naturally occurring compound found in the body and in various foods, particularly in beets, spinach, and whole grains. It is a derivative of the amino acid glycine and plays a role in the metabolism of methionine, an essential amino acid. DMG is often studied for its potential benefits in enhancing physical performance and supporting immune function. In addition to its biological functions, DMG is available as a dietary supplement. Some people take it to improve energy levels, cognitive function, and overall well-being. However, scientific research on its effectiveness and safety is still ongoing, and it is important to consult a healthcare professional before starting any new supplement.
