>>20917The primary importance of trimethylglycine (TMG) is as a methyl donor in the body. It donates a methyl group to convert homocysteine back into methionine, an essential amino acid. This reaction supports the methionine cycle, which is critical for producing S-adenosylmethionine (SAM), the body's universal methyl donor. SAM is involved in DNA methylation, neurotransmitter synthesis, and many other processes.
Dietary intake of TMG contributes meaningfully to methylation capacity, especially when choline or folate intake is limited.
