BHMT (Betaine-Homocysteine S-Methyltransferase): BHMT is an enzyme that indicates the body’s capacity to metabolize homocysteine, a process crucial for cardiovascular and neurological health. BHMT catalyzes the conversion of homocysteine into methionine using betaine as a methyl donor. Dysregulation of BHMT can result in elevated homocysteine levels, which are linked to cardiovascular disease and other health issues.
