Methyl Support with TMG

What Is Methyl Support with TMG?

Betaine anhydrous, better known as trimethylglycine or TMG, was first isolated from sugar beets. It is glycine wearing three methyl groups. Around it sit four B vitamins, each already in the coenzyme shape enzymes grab hold of: riboflavin 5'-phosphate, pyridoxal 5'-phosphate, two folates and methylcobalamin.

How It Works in the Body

Methylation is one small chemical move repeated everywhere: a single carbon atom, carried as a methyl group, passed from one molecule to the next. TMG hands one of its three groups over directly. Methylfolate and methylcobalamin work the other way in, through the folate cycle that regenerates methionine. Riboflavin becomes FAD and pyridoxal 5'-phosphate is the coenzyme form of B6; both are cofactors the folate and sulfur pathways lean on.

What It Supports

• Methyl donors: TMG, methylfolate and methylcobalamin each carry methyl groups into the cycle.
• Homocysteine: Together they support homocysteine levels already within the normal range.
• B-vitamin cofactors: Riboflavin and B6 act as cofactors in folate and amino acid chemistry.
• Nervous system: Methylation supplies the groups used to build neurotransmitters and myelin.

Who It May Suit

People who prefer B vitamins supplied in coenzyme forms. Adults on plant-based diets, since B12 is absent from plant foods. Anyone building a routine around the methylation cycle as a whole rather than around one vitamin at a time.

Good To Know

The folate here is split between calcium folinate and a methylfolate glucosamine salt, so it enters the cycle at two points. Talk with your healthcare provider before use, especially if you are pregnant or take methotrexate, which works by blocking folate.
