What Is The Methylation Cycle? - Nutrition Genome
See more on nutritiongenome.comThe methylation cycle is the process of transferring methyl groups (CH3) to DNA, turning switches off and on which change the gene expression but not the sequence. The methylation cycle relies on folate, B6, B12, B2, choline (60% of dietary methyl groups are from choline) and betaine to maintain normal homocyst…- Estimated Reading Time: 2 mins
