Genetics and Methylation

Methylation and MTHFR

Methylation is the passing of a chemical called a methyl group (a carbon atom linked to three hydrogen atoms) from one molecule to another. The easiest way to understand methylation is to think of it as a domino effect in your body.

The Methylation cycle is responsible for the function of:

  • Homocysteine
  • SAMEe
  • Methionine

The MTHFR gene provides instruction for making an enzyme called "methylenetetrahydrofolate reductase." This enzyme plays a role in processing amino acids, the building blocks of proteins. Methylenetetrahydrofolate reductase is important for a chemical reaction involving forms of the B-vitamin folate (also known as folic acid or vitamin B9). Specifically, this enzyme converts 5, 10-methylenetetrahydrofolate to 5-methyltetrahydrofolate.


A single-nucleotide polymorphism (SNP, pronounced snip; plural snips) is a DNA sequence variation occurring when a single nucleotide- A, T, C or G- in the genome (or other shared sequence) differs between members of a biological species or paired chromosomes in a human.

Functions of Methylation
  • Epigenetics (turns genes on/off)
  • Protects and Stabilizes DNA
  • Activates and/or Deactivates Stress Hormones
  • Activates Serotonin, Melatonin and Dopamine
  • Energy (ATP) Production
  • Growth and Healing
  • Autonomic Nervous System (ANS)
  • Immune System
Methylation Signs and Symptoms
  • Chronic Fatigue
  • Sleep Disorders
  • Inability to Adapt to Stress
  • Toxic Encephalitis
  • Genetic Disorders
  • Hormone Dysregulation
  • Cancer
What Causes Your Methylation to Fail?

There are many variables involved in a faulty Methlyation cycle, such as:

  • Genetics
  • DIet
  • Over consumption of sugar
  • Deficiency of B12 or Folate
  • Malabsorption
  • Toxins
  • Stress
