{"product_id":"b12-methylcobalamin-20mg","title":"B12 methylcobalamin 20mg","description":"\u003cp\u003eMethylcobalamin is one of the naturally occurring cobalamin forms of vitamin B12, distinguished from cyanocobalamin by the methyl group bound to the central cobalt atom. It functions as a cofactor for methionine synthase in the conversion of homocysteine to methionine, placing it within the one-carbon metabolism and methylation pathways.\u003c\/p\u003e\n\u003cp\u003eResearch interest in the methylcobalamin form centres on its direct participation in methylation reactions without the intermediate conversion required by cyanocobalamin, and on cobalamin status as it relates to homocysteine concentration and neurological endpoints.
