The Diploma in Performance Nutrition combines current science with practical application through comprehensive case studies. This is an evidence based rigorous program that instills confidence in the material both academically and practically. I highly recommend this program to anyone looking to competently understand and practice sports/performance nutrition.

This step-by-step course is a must for anyone interested in working in the field of sports nutrition. With every lecture given by internationally recognised experts, it has given me the tools and confidence to work within elite sport. The case study for each module is an amazing way to apply the ‘rocket-science’ in a practical, real-life event, that we are likely to encounter in our professional practice. Where this course really stands out above other Nutrition courses is the support from the highly-qualified team at the Institute of Performance Nutrition. Each tutor is fully committed to the growth and success of their students.

My experience of the Diploma in Performance Nutrition has been extremely enjoyable. The level of learning material in each module that can be practically applied is truly amazing and a testament to the hard work that Laurent and the team have put in. The tutors are very good at responding and give detailed feedback to help assist in the translation of the latest science into practice. The diploma encourages you to be a critical thinker in both a theory and practical sense. This course has motivated me even more to learn and progress in the competitive field of sports nutrition, which in itself, is a testament to the quality and learning environment of the program.

The Diploma in Performance Nutrition for me has been a fantastic experience. What sets this course apart is the intuitive online platform, varied course content and excellent tutor support. It really is second to none!
I can honestly say I have learnt so much, not only about nutrition for sport and exercise physiology, but also how to practically apply the knowledge to real world scenarios
