Engaging and informative modules that develop with you


There are four key themes running through the BSc (Hons) Nutritional Therapy degree: 

  • nutrition science
  • behaviour change and reflection
  • innovative research
  • extensive clinical practice experiences.

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 not only teaches you the essentials of nutritional therapy, but enables you to develop your critical thinking, analytical ability and communication skills; ensuring you are confident and ready for professional practice. 

Feed your passion

At the Institute for Optimum Nutrition, 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, combined 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. 

Importantly, we offer extensive opportunities for hands-on clinical practice. Find out more below.
