What Is Functional & Genetic Health Testing?
Nutrigenomics explores the relationship between your genes and nutrition, helping to determine how your body processes vitamins, minerals, and macronutrients. This genetic-based dietary assessment allows us to personalise nutrition, supplements, and lifestyle recommendations.
Meanwhile, functional testing examines how your body is performing on a biochemical level, assessing areas such as:
- Nutrient Deficiencies & Absorption Issues
- Gut Health & Microbiome Balance
- Hormone Levels & Metabolism
- Food Sensitivities & Intolerances
By combining nutrigenomics and functional health diagnostics, we can help you achieve sustainable health improvements through tailored lifestyle interventions.
