What does an Integrative Nutritional Therapist do?
Plus icon, svg, dark

An Integrative Nutritional Therapist utilises the latest evidence-based research to create an integrative approach to optimising each client’s health and wellbeing.

They design bio-individual nutrition plans, personalise supplementation where appropriate, and interpret functional laboratory data, including blood work, to gain deeper insights, achieve better accuracy and tailor every intervention to the individual.

How is functional medicine different from conventional medicine?
Plus icon, svg, dark

Conventional medicine often waits until a disease is clearly present before intervention begins. Treatment is focused on managing or suppressing a diagnosed condition.

Functional medicine looks upstream. It assesses the early drivers of dysfunction and works to prevent disease from developing in the first place, or restore balance in the body. It uses a whole-systems view of the body, then applies personalised, preventative nutrition and lifestyle interventions to support long-term health rather than only reacting once things have gone wrong.

What will be my scope of practice after completing this certification?
