Our goal is to not have a single piece of inaccurate information on this website. They are continually monitored by our internal peer-review process and if we see anyone making material science errors, we don't let them write for us again. Our science team must pass long technical science tests, difficult logical reasoning and reading comprehension tests. Our science team is put through the strictest vetting process in the health industry and we often reject applicants who have written articles for many of the largest health websites that are deemed trustworthy. Our team comprises of trained MDs, PhDs, pharmacists, qualified scientists, and certified health and wellness specialists.Īll of our content is written by scientists and people with a strong science background. We are dedicated to providing the most scientifically valid, unbiased, and comprehensive information on any given topic. We believe that the most accurate information is found directly in the scientific source. As a nutritional supplement, DMG acts as a building block for the synthesis of many important substances such as choline, SAM-e, the amino acid methionine, several hormones, neurotransmitters and DNA.SelfHacked has the strictest sourcing guidelines in the health industry and we almost exclusively link to medically peer-reviewed studies, usually on PubMed. Humans also naturally produce DMG in small amounts. DMG is a normal physiologically active nutrient found in low levels in such foods as cereal grains, liver and beans. DMG (dimethylglycine) is basically the amino acid glycine attached to two methyl groups. It may also be useful for controlling epileptic seizures. It improves oxygen utilization by the body, helps to normalize the functioning of many important organs. DMG has been found to enhance the immune system and to reduce elevated blood cholesterol and triglyceride levels. Taking supplemental DMG can have a wide range of possible beneficial effects, including helping the body maintain high energy levels and boosting mental acuity. DMG that is not metabolized in the liver is transported by the circulatory system to various tissues in the body. DMG itself is formed from trimethylglycine or betaine.
The methyl group produced in this reaction returns to the one carbon pool at the level of N10-hydroxymethyl-tetrahydrofolic acid. Dimethylglycine dehydrogenase, a flavoprotein, is the enzyme that catalyzes the oxidative demethylation of DMG to sarcosine. DMG is metabolized in the liver to monomethylglycine or sarcosine which, in turn, is converted to glycine. DMG is absorbed from the small intestine and from there transported by the portal circulation to the liver. TMG is involved in the methylation of homocysteine to form methionine (see Trimethylglycine).
DMG should not be confused with TMG (trimethylglycine or betaine). DMG is also known as N, N-dimethylglycine, (dimethylamino) acetic acid and N-methylsarcosine. DMG is neither a vitamin nor an essential nutrient. None of those claims, however, was ever substantiated. At present, DMG supplements are available that do contain dimethylglycine.ĭMG-containing calcium pangamate was popular with Russian athletes and cosmonauts because it was reputed to enhance oxygenation at the cellular level, reduce fatigue and enhance physical stamina. Some of these products contained, instead of Dimethylglycine, a substance called diisopropylammonium dichloroacetate. However, several products entered the supplement marketplace called pangamic acid or calcium pangamate, and these did not contain Dimethylglycine. Calcium pangamate was intended as a delivery form of Dimethylglycine. Calcium pangamate was originally a mixture of calcium gluconate and DMG. DMG appeared as a supplement in the 1960s under the names vitamin B15, pangamic acid and calcium pangamate. There has been much confusion surrounding the history of DMG as a nutritional supplement. It acts as a building block for many important substances, including the amino acid methionine, choline, a number of important hormones and neurotransmitters, and DNA. DMG is produced in cells as an intermediate in the metabolism of choline to glycine. It is a non-protein amino acid found naturally in animal and plant cells.
