DNA Methylation Deep Dive
Methyl groups: tiny tags, huge impact
DNA methylation adds a small chemical group (CH₃) to cytosine bases in your DNA. This silences genes. As you age, methylation patterns change — some genes that should be silent turn on, and vice versa.

The methylation cycle needs B vitamins + choline
Methyl groups don't appear from nowhere. The body's methylation engine runs on methionine → SAMe (the universal methyl donor) → homocysteine → back to methionine. The cycle requires folate (B9), B12, B6, riboflavin (B2), choline, and betaine. Deficiency in any of these — common with aging — disrupts the entire methylome. Eggs (choline), leafy greens (folate), and fish (B12) are the cheapest insurance.

Key Takeaway
Methylation is the language of epigenetic aging. Folate-rich foods, exercise, and good sleep maintain healthy methylation. Alcohol, smoking, and stress accelerate epigenetic aging.
