Synergy
What is happening. B6, B12, and folate work together to metabolize homocysteine. All three are needed for optimal methylation.
Mechanism. B6 (as PLP) is cofactor for cystathionine beta-synthase (transsulfuration pathway). B12 for methionine synthase (remethylation). Both pathways clear homocysteine.
Recommendation. Take B6, B12, and folate together for comprehensive homocysteine management and methylation support.
