Scope of Practice & Professional Disclaimer
Nutritional Therapy and Lifestyle Medicine is the application of nutrition and lifestyle medicine sciences in the promotion of health, peak performance, and individual care. Registered Nutritional Therapy Practitioners (RNTPs) assess and identify potential nutritional imbalances and understand how these may contribute to an individual’s symptoms and health concerns. This approach allows them to work with individuals to address nutritional imbalance and help support the body towards maintaining health.
Our Approach
Nutritional therapy is recognised as a complementary medicine and is relevant for individuals with chronic conditions, as well as those looking for support to enhance their health and wellbeing. Practitioners consider each individual to be unique and recommend personalised nutrition and lifestyle programmes rather than a ‘one size fits all’ approach.
Personalised nutrition is tailored specifically for you, taking into account your health journey, your health goals, and dietary preferences.
Consultations are relevant for individuals with chronic conditions (such as diabetes, obesity, and cardiovascular disease), those with persistent digestive issues, or those wishing to support an autoimmune condition.
