BSc (Hons) Nutritional Therapy

Neetha came to ION looking for answers after her daughter’s autoimmune diagnosis. Four and a half years later, her degree research is turning heads. Studying people on GLP-1 medications, she found every participant fell short on fibre, only half met basic protein needs, and 92% of the UK group were low in selenium. She shares what the degree taught her, the lecturer who championed her, and how she now works across private and NHS settings.

Legacy Course

Leah's path into nutrition ran from a biomedical sciences degree through years running national surveillance programmes at the Health Protection Agency and Public Health England, before training at ION to bridge the gap between population-level prevention and individual behaviour change. That thinking shaped her work well beyond the clinic, including co-designing the Inspire programme and piloting a Black Health and Wellbeing Day in Lambeth that delivered around 200 referrals into local services. Today, through The Thrive Practice, she treats client work like detective work, building plans over months so people feel empowered to understand their own bodies, not dependent on her.

BSc (Hons) Nutritional Therapy top-up

Diana Warrings left a fifteen-year fashion career in her early 40s to retrain in nutrition through ION, building a Berlin-based practice spanning consultations, recipe development, and cooking workshops. Now completing her BSc with a thesis on menopause, she's moving into corporate health work focused on women's wellbeing—living proof that it's never too late to change course.

Legacy Course

Anastasis Tzanis swapped airborne training for the trading floor, then walked away from a six-year finance career to become a nutritional therapist. His path from currency derivatives to the clinic reveals what high-pressure careers do to the body, why adaptability cuts both ways, and how the discipline forged in the forces can become the foundation of a rewarding second career.

Graduate Diploma Integrative Functional Nutrition

After a borderline pre-diabetic blood test sparked a personal health transformation, David Sogan – now in his final year of ION's Graduate Diploma in Nutritional Therapy – channelled that wake-up call into action.
