Please note:
In the UK, nutrition and diet advice is a voluntary, unregulated profession (outside of protected titles such as “Dietitian” or “Registered Nutritionist,” which require specific university degrees and statutory registration).
This course equips you to practise as a Nutritional Advisor, offering safe and ethical guidance on healthy eating, wellbeing, and lifestyle support within the scope of your training.
Graduates must not use protected titles (e.g., “Dietitian” or “Registered Nutritionist”), claim to diagnose or cure medical conditions, or advise clients to discontinue prescribed medical treatment.
All information provided is for educational and professional development purposes. It should never replace medical advice from a qualified healthcare professional.
By completing this course, you’ll gain the knowledge, confidence, and professional recognition to start offering nutritional guidance, support clients’ wellbeing, and build a successful practice — backed by CMA accreditation and professional insurance.
