"I left feeling genuinely inspired." 💚

That's the feedback we love to hear from our Open Day attendees, and it's exactly how one future student described her experience with us.

She found the whole day invaluable, from hearing real stories from our graduates to finally understanding the difference between a nutritionist, a dietitian and a nutritional therapist. She learned how our technology keeps evolving to support students, discovered the breadth of career paths open to her, and felt part of a genuine community from the moment she walked in.

Now, she's ready to apply for our BSc (Hons) Nutritional Therapy, validated by the University of Portsmouth.

Curious what an ION Open Day could do for you? Join us at one of our upcoming events:

Interested in nutrition and want to make it your career, but confused by all the different terminologies? 🌱

Dietitian, nutritionist, nutritional therapist... they sound similar, but they're not the same job. Swipe through to see exactly what sets a nutritional therapist apart.

At its heart, nutritional therapy is all about personalised nutrition. It's not a generic diet plan, it's looking at your body, your lifestyle and your history to work out what will actually help you feel better. That's what makes it such a powerful, hands-on way to support someone's health.

Curious where it could take you? Our next online open event is on 11 September, or download our prospectus to explore your options. You can also call one of our friendly course advisors for a chat.

Our next CPD course focuses on the scientific evidence underpinning fasting and its role in supporting metabolic health, cellular resilience and healthy ageing.

It examines the different fasting approaches available, explores the biological mechanisms behind their effects, and critically evaluates the current research, from time-restricted eating to fasting-mimicking diets.

Participants will gain practical guidance on screening clients, understanding safety considerations, and confidently incorporating evidence-based fasting strategies into practice.

Led by nutritional therapist Layla Gordon.

Join us for Mitochondria: Cellular Motherboard, a special seminar held in tribute to our late Dean, Heather Rosa.

Heather was planning this very event before she passed, exploring one of the most exciting frontiers in modern medicine: the role mitochondria play in energy, metabolism, immune health, ageing and disease. Far more than the "powerhouse of the cell", they're the command centres driving human health.

Join friends, colleagues, students, alumni and healthcare professionals for an afternoon of tribute, followed by expert talks from Emma Beswick, Dawn Waldron and Moira Newiss, plus a live panel Q&A.

📅 30 October 2026, 3.30pm–7.45pm
📍 BMA House, Tavistock Square, London
🎟️ £60

MEET OUR ION STUDENT!

Her background is in medicine. As she puts it: "There is definitely a role for nutrition in traditional medicine."

Many of our students come from careers in the NHS, and they've found the same gap: food and personalised nutrition are real medicine.

Late enrolment is now open for our BSc (Hons) Nutritional Therapy, Cert HE Personalised Diet and Health, BSc (Hons) Nutritional Therapy Top-up, and Return to Practice.

We've also just launched our new Postgraduate Diploma in Personalised Nutrition & Lifestyle Medicine* subject to validation, a master's-level course for medical and healthcare professionals, starting February 2027!

Be the next generation of nutritional therapists or nutrition and lifestyle advisors, and change lives.
