Dimethylglycine and Autism Ranking: Limited negative evidence

Key Features

According to the Memorial Sloan Kettering Cancer Center website, accessed on 16 January 2017,

“Dimethylglycine (DMG) is a derivative of the amino acid glycine. It is found naturally in plant and animal cells and in certain foods such as beans, cereal grains, and liver. DMG is produced in cells during the metabolism of choline and is considered an antioxidant and enhancer of oxygenation at the cellular level”

According to the Autism Research Institute (2008),

“Dimethylglycine is technically classified as a food. It is found, in very small amounts, in some foods, such as brown rice and liver. Chemically and physiologically, it resembles the water-soluble vitamins, such as the B vitamins. The main reason it is not classified as a vitamin is that there are no specific symptoms associated with a deficiency of DMG.”

DMG comes in a variety of forms including capsules, tablets and in liquid form.


According to the WebMD website, accessed on 16 January 2017,

“The appropriate dose of dimethylglycine depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for dimethylglycine. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.”
