Products with Betaine

Interactions

synergistic. Betaine (TMG) donates methyl groups for creatine synthesis in the liver; both support power output and body composition through independent mechanisms

synergistic. Betaine provides an alternative pathway for homocysteine remethylation via BHMT enzyme, complementing the folate-dependent methionine synthase pathway

synergistic. Both support methionine cycle — B12 as cofactor for methionine synthase, betaine as alternative methyl donor via BHMT; redundant homocysteine clearance pathways
