Methyl Friendly

for Methy-friendlier Living

Understanding that methylation is one of the most significant processes in humans may be your first step towards even better health—for yourself, your community, the marketplace, and the world.

Why Methylation Matters

DNA • Energy • Mood

Controls gene expression, detox, neurotransmitter production.

Common Issues

MTHFR variants, high homocysteine, synthetic folic acid buildup.

The Science

Methylation is

Happening billions of times a day

in your cells and acts like a molecular switch, turning biological processes on or off.

Helping regulate gene expression

by adding methyl groups to DNA, which can silence or activate specific genes.

Supporting the liver

in detoxifying harmful substances by making them water-soluble for excretion.

Aiding in producing neurotransmitters,

which are critical for mood, focus, and brain health.

Methylation Milestones

A historical timeline of key events and leading voices in human DNA methylation

  1. 01

    1925 – 1948: Discovery of 5-Methylcytosine

    5mC first reported in bacteria (1925), then discovered in mammalian DNA by Rollin Hotchkiss in 1948 (calf thymus).1,2

  2. 02

    1940s–1950s: Conrad Waddington & Epigenetics

    Waddington coins the term “epigenetics” (1942) and introduces the epigenetic landscape concept (1957).3

  3. 03

    1960s–1975: Functional Role Established

    Bacterial restriction-modification systems (1960s) and Arthur Riggs proposes DNA methylation as a stable gene silencing mechanism (1975).4

  4. 04

    1983: Link to Human Cancer

    Andrew Feinberg & Bert Vogelstein discover global DNA hypomethylation in human cancer.5

  5. 05

    1990s: Genomic Imprinting & DNMTs

    Discovery of genomic imprinting and cloning of key DNA methyltransferases (DNMT1, DNMT3A, DNMT3B).6

  6. 06

    2000s: Dutch Hunger Winter & Amy Yasko

    Persistent methylation changes from prenatal famine documented. Dr. Amy Yasko develops detailed methylation cycle protocols and SNP analysis.7,8

  7. 07

    2013: Steve Horvath Epigenetic Clock

    Steve Horvath introduces the first DNA methylation-based epigenetic clock for biological age prediction.9

  8. 08

    2010s–Present: Popular Voices & Clinical Advances

    Ben Lynch and Gary Brecka popularize methylation testing and optimization. Methyl Health publishes definition for neurotransmissive support and files formally. Manel Esteller and Peter Laird advance cancer methylome research. Infinium MethylationEPIC array released.10,11
