As a cofactor for methionine synthase and methylmalonyl-CoA mutase, methylcobalamin plays a central role in one-carbon metabolism, myelin sheath synthesis, DNA methylation, and red blood cell maturation in research models. It has been studied for its neuroprotective properties, nerve regeneration support, and involvement in homocysteine remethylation pathways and mitochondrial energy metabolism.\u003c\/span\u003e\u003c\/p\u003e","brand":"PepXClub","offers":[{"title":"10mg \/ 1 BOTTLE","offer_id":49815736058095,"sku":null,"price":45.0,"currency_code":"USD","in_stock":true},{"title":"10mg \/ 3 BOTTLES","offer_id":49815736090863,"sku":null,"price":45.0,"currency_code":"USD","in_stock":true},{"title":"10mg \/ 5 BOTTLES","offer_id":49815736123631,"sku":null,"price":45.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0821\/9554\/6351\/files\/3.png?v=1781525908","url":"https:\/\/shop.pepxclub.com\/products\/b12","provider":"PepXClub","version":"1.0","type":"link"}
