Betaine CAS#107-43-7
Supports Liver Health – Acts as a methyl donor, aiding in liver function and overall metabolic processes.
Promotes Cellular Activity – Contributes to cellular reproduction and energy-related functions.
Enhances Nutrient Synthesis – Plays a role in the production of carnitine, important for fat metabolism.
Maintains Cellular Balance – Regulates hydration and supports proper cell function.
Betaine, also known as betaine anhydrous or trimethylglycine (TMG), is a methyl group donor that supports liver function, cellular reproduction, and the synthesis of carnitine. It is an amino acid betaine and a derivative of glycine, playing an important role in regulating cellular hydration and maintaining proper cell function.

Betaine is an active ingredient in toothpaste for alleviating dry mouth symptoms. It is used to treat homocystinuria, a disorder affecting the primary pathway of methionine metabolism. Additionally, it supports immune system function, enhances athletic performance, and may help prevent noncancerous colon tumors (colorectal adenomas).
