We therefore turned to a detailed computational model of 1-carbon metabolism to revisit the remethylation-block hypothesis and investigate the lack of correlation between vitamin B 12 deficiency and GSH
Its proposed mechanisms include the promotion of angiogenesis (formation of new blood vessels), enhancement of collagen production, and support of the gut-tissue axis for improved gut health

Those with MTHFR gene mutations lack the enzyme required to activate folic acid, which can result in a buildup of unmetabolized folic acid (UMFA)
Christen and colleagues found that daily supplementation with 2.5 mg of folic acid, 50 mg of vitamin B6, and 1 mg of vitamin B12 for seven years reduced homocysteine levels by 18% in 300 women with three or more risk factors for coronary heart disease but did not affect other cardiovascular inflammatory biomarkers.24 Another study by Kataria and colleagues demonstrated that daily supplementation of 2 mg of folic acid, 25 mg of vitamin B6, and 0.5 mg of vitamin B12 resulted in an 11% reduction in risk of vascular death among 8,513 stroke patients but had no effect on cardiovascular risk.25 In addition, treatment for four weeks with oral doses of 1.8 g/day of N-acetylcysteine, a precursor to the antioxidant glutathione, has been found to lower blood homocysteine levels by reducing cellular oxidation, but has not consistently reduced the risk of cardiac events in cardiovascular patients.26,27 The reasons for the lack of protective effects of folic acid, vitamin B6, and vitamin B12 on inflammatory biomarkers and risk of CVD are unclear
