Dimethylglycine (DMG) is a naturally sweet-tasting food substance found in cereal grains and meats. While clinical studies are lacking, DMG is promoted for being an immune stimulant, as well as for being able to increase oxygenation of the tissues, improving athletic endurance and diminishing muscle fatigue.
Dimethylglycine (DMG) supplements are available in capsules, bulk powder and liquid extracts.
