    5 star review  Having had a number of issues with food allergies, eating habits and my low moods, Jessica O’Dwyer helped identify where the problems lay and provided me with the support and practical advice I needed to overcome them.Jessica has great empathy and at times, when I felt discouraged, she was able to encourage me into positive action. Changing eating habits is hard but with Jess’s moral and clinical support I am in a much healthier place, both mentally and physically than when I started over 3 months ago.Jess will not overwhelm you with the detail, but explains things clearly and gives practical advice which even a simple man can follow.My experience of working with Jessica is of an extremely courteous, professional, knowledgeable and empathetic nutritionist who is passionate about her job and helping people.If you are unsure or wondering where to begin, I would not hesitate to contact Jessica O’Dwyer to discuss your needs.

    5 star review  I have had a great experience at the London Clinic of Nutrition with Katherine personally. We worked together to get a good diet plan I was diagnosed with Celiac and Hashimoto’s which I was unaware of and Katherine did an amazing job educating me about the benefits of a ketogenic diet and a calmer lifestyle. I have since introduced both my parents to the clinic and they are working with Helen with dramatic results in health improvement and wellbeing. I do not hesitate to recommend this Clinic they are so knowledgeable and professional. No need to travel to London either you can do the consultations via Zoom.!

    5 star review  My experience at London Clinic of Nutrition has been really fantastic. Their expertise in treating chronic autoimmune conditions is, in my experience, unsurpassed. The IV area is comfortable and relaxing and the nurses and staff go to every effort to make you feel at home. I would really recommend having IV's here – I have been to several clinics in London and this has been the best by far. The staff are also very welcoming, attentive and good at explaining the intricacies of the treatment in a very understanding way. The practitioners help and work with you to inform you and understand your health condition and make a treatment plan together. Oliver has really helped me to get to the root causes of my health issues in a way that has been manageable and considered.
