Blog: What is methylation & why does it matter

Image: DNA image

Most people have never heard of methylation, yet it’s one of the most important processes in the body — impacting energy, mood, hormone balance, detoxification, and more.

In this blog, I explain what methylation is, how your genes (like MTHFR and COMT) influence it, and why personalised nutrition and genetic testing can be a game-changer for your health.

I also explore how experts like Gary Brecka have brought this to public attention — and how I use these tools clinically to support clients with fatigue, anxiety, perimenopause and more.
