What is the main advantage of studying at ION? Since ION was founded by Patrick Holford in 1984, ION has rapidly established itself as one of Europe’s leading providers of Nutritional Therapy and education. The Nutritional Therapy Diploma Course was the first undergraduate course to be recognised by the NTC (Nutritional Therapy Council) now known as NTEC (Nutritional Therapy Education Commission). ION is very much a ‘voice for nutrition’ and is highly respected for both the nutritional and clinical excellence of ION graduates throughout the UK. Students who graduate from ION with a DipION qualification are able to register with BANT (British Association for Nutrition and Lifestyle Medicine) and register with CNHC (Complementary & Natural Healthcare Council).
