Hannah Alderson BA(Hons) DipCNM mBANT mIFM regCNhC is registered with the British Association of Nutrition and Lifestyle Medicine (BANT), a member of The British Menopause Society, a member of The Institute of Functional Medicine, regulated and governed by the Complementary and Natural Healthcare Council which is an accredited nutrition register regulated by the Professional Standards Authority of the United Kingdom and fully insured. 

Following a 10 year career in the creative industry (working in Theatre and then for a Global Design & Branding agency), Hannah trained for three years at the world renowned College of Naturopathic Medicine in London, qualifying as a Registered Nutritional Therapist. Her training continued with the Institute of Functional Medicine and the University of Functional Medicine. Hannah attended and completed the AFMCP™-UK training in London where IFM educates health care professionals how to apply these principles in practice through an intensive training course called Applying Functional Medicine in Clinical Practice™. Hannah now runs her practice in Berkhamsted Hertfordshire, specialising in women's health, utilising her nutritional expertise and exceptional rapport with people. As a member of BANT and The Institute of Functional Medicine Hannah continues extensive postgraduate training to expand her expertise and deepen her knowledge in the practice of evidence based Nutritional Therapy and Functional Medicine. 

Hannah has worked with with Global consumer healthcare provider GlaxoSmithKline, supporting consumer research into a personalised nutrition service for PCOS sufferers. Having an opportunity like this to understand how we can better support the PCOS community on a global scale was a true privilege. 

Hannah is on the medical advisory board for the PCOSAA (Polycystic Ovarian Syndrome Awareness Association). The PCOS Awareness Association is a not for profit organisation dedicated to raising the awareness of this disorder worldwide, providing educational and support services to help people understand what the disorder is and how it can be treated. Hannah has hosted many webinars and was honoured to have been invited onto the expert panel for the PCOS Awareness Association's international annual event to promote PCOS education and raise awareness.

Hannah Alderson Nutritionist Berkhamsted PCOS


After receiving a Diploma in Acting from London’s prestigious Mountview Academy of Theatre Arts, Hannah went on to gain a First Class Honours Degree in Theatre Production from London South Bank University. Upon graduation, she was awarded the Royal National Theatre Student Award in 2009 and was privileged enough to be invited back to be a lecturer. Hannah immersed herself in the world of theatre working in London, Edinburgh and New York. Everyone has a story that brings them to discover the importance of nutrition, and this was it for Hannah. Late nights and long hours led to a black coffee lifestyle more disco than dynamic yoga.


Inevitably burnout followed, as well as troublesome hormonal and endocrine issues suffering from PCOS, Endometriosis and ezcema. She left the Theatre world and joined a Global Design and Branding agency, whilst her interest in Nutrition started to gain momentum. What followed out of this was an understanding that nutrition plays a leading role when it comes to your health and happiness. The right guidance can be just the tonic to navigate the complexities of modern life, and it was at this point Hannah embarked on her journey to qualify as a Nutritional Therapist and heal herself so that she could reclaim her health and become a mum.


What is a nutritionist? Well, calling yourself a nutritionist or nutrition coach doesn’t mean you’ve necessarily got the qualifications behind you, as the term 'nutritionist' is not a protected title -  anyone who claims to be an expert in the field of nutrition can technically call themselves a nutritionist. Although you may be able to call yourself a nutritionist or coach, these individuals will not be be able to belong to a professional governing body. A professional body, such as BANT, supports its members in attaining the highest standards of integrity, knowledge, competence and professional practice, in order to protect the client’s interests, nutritional therapy and the Registered Nutrition Practitioners.


Unlike nutrition coaches or unregistered nutritionist, a Registered Nutritionists would have spent many years studying and provide clients with evidence-based information and guidance about the impacts of food and nutrition on health and wellbeing. Always check that any healthcare provider you take advice from is registered and regulated by a governing body and is fully insured, such as myself.


Dieticians generally work within the NHS and public health sector. A dietitian would hold a degree in Nutrition and Dietetics and would be regulated by the Health and Care Professions Council. Only dieticians and Registered Nutritional Therapists are trained in clinical practice to give one-on-one personal health advice. Both groups must practice with full professional indemnity insurance.


I am a Registered Nutritional Therapist who is appropriately qualified, holding a recognised qualification in Nutritional Therapy and membership at two governing bodies, BANT and CNHC. Using a Functional Medicine approach I assess and identify potential nutritional imbalances and understand how these may contribute to an individual's symptoms and health concerns. As a Registered Nutritional Therapist, my private clinic specialises in weight management and weight (fat) loss programmes, hormone health such as PCOS and endometriosis, anxiety, stress and digestion. As a BANT registered Nutritionist I’m able to one to one consultations, provide corporate workshops, events and comment via media outlets such as TV, print and digital publications.
