Key Takeaway
Methylation pathways are critical for DNA regulation, neurotransmitter synthesis, and detoxification, with key nutrients including folate, B12, and methionine.
Summary
This comprehensive review examines the role of one-carbon metabolism and methylation in human health.
Methylation reactions depend on adequate intake of folate, vitamin B12, B6, and other cofactors. These pathways affect gene expression, neurotransmitter production, and detoxification capacity.
