'''Trimethylglycine (TMG)''', commonly known as '''betaine''', is an amino acid derivative that naturally occurs in various plant and animal sources. With its three methyl groups attached to a glycine molecule, TMG has garnered attention in both the dietary supplement market and the scientific community due to its role as a [[Methyl Donors|methyl donor]] in vital biochemical processes.

The story of TMG traces back to the early 20th century when it was first isolated from sugar beets, hence the name "betaine" after the Latin name for beet, ''Beta vulgaris''. Over the years, researchers have identified its presence in numerous foods and its key functions within human metabolism. As the exploration of its potential benefits continued, TMG started to gain traction, especially in discussions related to heart health, liver function, and, more recently, longevity.
