Understanding Methylation Genetics: A Quick Tutorial Series

Methylation is a biochemical reaction in which a methyl group (CH3) is attached to a molecule, converting it to a different molecule that the body either needs (e.g. neurotransmitter) or can easily dispose of if not needed (e.g. certain hormones and toxins).  

Methylation requires a variety of nutrients and plays dozens of indispensable roles, including neurotransmission, hormone detoxification, amino acid metabolism, vitamin assimilation, homocysteine clearance, cell membrane structure and gene regulation.  Health professionals who deal with cardiovascular, neurocognitive and mental health cases can gain insight into nutritional interventions by understanding the basics of this process, which I describe in this tutorial series.
