Nutritional Therapy

Conventional health care deals mostly with chronic degenerative disease, but does little to address the underlying causes that are often rooted in poor dietary and lifestyle habits.

What is Nutritional Therapy?

Nutritional Therapy, the core component of Functional Medicine, is a holistic, person-centered approach that uses whole foods, phytonutrients, therapeutic food supplements and lifestyle changes to assist clients to restore and safeguard sound health.

What does a Nutritional Therapist do?

Following a comprehensive interview, the Nutritional Therapist and client discuss and agree a programme of dietary and lifestyle recommendations based on the client’s unique needs – often supported by functional test findings – and their personal preferences and circumstances. Follow-up appointments to monitor progress and provide further advice and support take place over the following weeks or months.
