what if your DNA knows what you need?
Sep 15, 2026
What if your body isn't failing you?
What if you've simply been working from the wrong instructions?
As we continue our longevity series, I'm joined by Emma Beswick, founder and CEO of LifeCode GX, to explore a fascinating question:
What can your DNA tell you about how your body actually works?
This isn't about chasing the latest biohack.
It's about understanding the blueprint you were born with — and recognising that the same food, nutrient, or supplement doesn't necessarily work the same way for everyone.
We dive into nutrigenomics and nutrigenetics, exploring how small differences in our DNA can influence the way we process and respond to nutrients.
We also unpack two genes you've probably heard of:
COMT, which plays a role in processing compounds including dopamine, adrenaline, histamine and estrogen — and how it can intersect with stress and recovery.
And MTHFR, a common genetic variation involved in folate metabolism, and why supporting the pathway isn't simply about taking more supplements.
The bigger message?
Your genes may influence your needs, but they don't write your entire story.
Epigenetics reminds us that gene expression can be influenced by our environment, nutrition, lifestyle and other factors.
So before reaching for another complicated protocol, we go back to the foundations: essential nutrients, cofactors, food-first support, and understanding your individual context.
