About Us

The London Clinic of Nutrition was set up by Oliver Barnett a highly experienced  Nutritional Therapist and integrated medical practitioner in London and Hertfordshire.

Passionate Nutritional Therapist in London and Hertfordshire

consultationOliver has always been a keen cook (ex Masterchef finalist) and developed an early interest in food and nutrition. This led to five years of study in Naturopathy and Nutrition, which has been supplemented with post graduate courses and study in Metabolic Typing, iridology and herbal medicine. Regular seminars are attended to keep abreast of the latest evidence in conventional and natural medicine.
One of Oliver’s key interests is educating clients to dispel modern medical myths and to understand the impact of the current western diet on health. Oliver’s key interests are digestive disorders, auto-immune diseases, unexplained illness, Lyme disease,  women’s nutrition & hormones and food sensitivities.

Oliver is considered one of the UK’s leading health experts and regularly features in printed and online media.  Further, Oliver lectures at the top Nutrition colleges in London and corporate institutions.

Therefore Oliver has devoted his life to helping patients improve their health and as can be seen below a rigorous program of on-going learning and professional development continues each year so that he remains at the top of his game and his patients get the very best of care.

My session with Oliver Barnett was very interesting and informative and he told me how to build on my existing healthy diet, broadening what I ate and how I prepared it, and prescribed a course of herbs and a detox.
