Feed your passion.


Since 1984, the Institute for Optimum Nutrition has delivered internationally renowned nutritional therapy training. At ION, you will be taught to use the principles of personalised and functional medicine to inform your clinical practice. We combine the latest theoretical and applied knowledge from nutrition, science, and the psychology of behaviour change with ‘real world’ clinical training to help you build an in-depth understanding of the role that nutrition and lifestyle plays in human health and wellbeing.

The undergraduate degree will equip you with a comprehensive understanding of food, nutraceuticals, the use and interpretation of testing, and lifestyle modification. There are four key themes running through the degree: nutrition science; behaviour change and reflection; research; and practice.

This engaging and academically rigorous course will give you a thorough understanding of the therapeutic effects of foods and nutrients, and the ways in which you can address health and wellbeing issues through nutrition and lifestyle management.

Ultimately, this flexible course nurtures you through each subject in a way that makes it meaningful, building your confidence and enabling you to develop your critical thinking, analytical ability and communication skills; ready for professional practice. 

Hands on clinical experience

Our clinical skills training, delivered in the Optimum Nutrition Clinic, provides a critical opportunity to apply the knowledge you gain on the undergraduate degree to practise with real clients, whilst learning from experienced, fully qualified practitioners and specialists.

As an ION student you will also experience being a client in the training clinic; this will give you a client-side perspective and an insight into the experience of practice before you start your own clinical skills training.


Content and structure

The BSc (Hons) Nutritional Therapy is designed to allow for two pathways to completion, depending on your background and experience. Regardless of which pathway you take, you will complete and graduate with the same Bachelor of Science honours degree.

  1. Clinical training pathway

This pathway is for those students with no previous qualification in nutritional therapy. You will complete the qualification in full by joining in Year 1 (Level 4) of the degree and finish in Year 5 (Level 6) with a research project.

  1. Qualified nutritional therapist pathway

ION provides the only fast track pathway to an undergraduate degree in nutritional therapy using recognised prior certified and/or experiential learning (RPL) for those students who are already qualified nutritional therapists. 

Graduated from ION in the last five years?

You have the opportunity to use your DipION credits to top up to the degree. This could mean only needing to complete the last 120 credits of final level of study.

Graduated from ION over five years ago?

You have the opportunity to use your DipION credits and experiential learning to top up to the degree. The amount of credit and course length will be determined through the submission of a portfolio of evidence against the learning outcome of the course.
