Trimethylglycine, or TMG, is the amino acid glycine with three methyl groups attached. It is better known as betaine, a name taken from the sugar beet (Beta vulgaris), where it was first identified in the 19th century.
Food sources
Betaine occurs naturally in beetroot, spinach, wheat bran and wheat germ, quinoa and shellfish. Most supplement TMG is purified from sugar beet molasses.
Betaine vs betaine HCl
Do not confuse TMG (betaine anhydrous) with betaine hydrochloride, a different ingredient with an acid component. Labels should state which one they contain.
What to check before you buy
- The amount of each ingredient per serving, not just per capsule
- How many capsules make one serving and how many servings are in the pack
- Whether any ingredient sits inside an undisclosed "proprietary blend"
- An FSSAI licence number and the veg/non-veg mark on the pack
