BHMT (Betaine-Homocysteine S-Methyltransferase): BHMT is an enzyme that indicates the body’s capability to metabolise homocysteine, a process vital for cardiovascular and neurological health. BHMT catalyses the conversion of homocysteine to methionine using betaine as a methyl donor. Dysregulation of BHMT can cause elevated homocysteine levels, which are linked with cardiovascular diseases and other health issues.
