Methylation is an incredibly complex biochemical process that plays a ubiquitous role in the body’s maintenance. In very layman terms, it turns nutrients from the food that you eat into a type of fuel that your body uses to catalyse enzymes, which are involved in everything from mood regulation, fertility, detoxification of toxins and hormones, energy production, and vascular health.

In particular, having a dysregulated CAR - meaning it is either too high or too low - can lead to symptoms of depression, anxiety, affective disorders, chronic fatigue and increase risk of autoimmunity. This is because CAR has a unique ability to regular inflammation, blood sugar, as well as memory and recall due to the fact that the hippocampus is so tied in with CAR. It also plays a role in infection regulation and so can have far-reaching effects on the body’s resilience to viruses and bacteria.
