Is your thyroid health determined by more than just your food choices and lifestyle?

In this episode, I speak with Justin Harris, a certified functional genomics practitioner, who explains how understanding your genetic blueprint can unlock personalized strategies for managing thyroid health. We dive into how genetics influences key factors like oxidative stress, detox pathways, and autoimmune conditions such as Hashimoto’s and Graves' disease. Justin also shares how genetic testing can offer insights into your body’s unique response to food, exercise, and environmental factors. 

By understanding your genetic makeup, you can make more informed decisions about nutrition, supplements, and lifestyle changes. We also touch on the role of epigenetics in how your genes express themselves and how modifying your lifestyle can improve thyroid function and overall health.

Tune in to find out how your genes could be the missing piece.
