Functional and Nutrigenomic Testing

Functional and nutrigenomic (DNA) testing allows us to dig deeper into what’s happening inside your body, rather than guessing based on symptoms alone. These advanced tests can highlight imbalances, deficiencies, genetic variations, and functional issues that may be contributing to your health concerns.

By understanding your unique biochemistry, we can create a truly personalised plan—targeted nutrition, tailored supplements, and lifestyle recommendations that match your body’s specific needs. Testing isn’t always essential, but when used thoughtfully, it can help us get answers faster and guide your journey with greater precision.

During your consultation, I can advise whether any functional testing would be helpful for your specific situation.
