Nutritional Therapy


Registered Nutritional Therapy Practitioner (RNTP)

The Nutritional Therapy clinic at the Northern Centre of Integrative and Functional Medicine (NCIFM) is based on the Functional Medicine model, which sees good nutrition and digestion as the foundation for health. Using an evidence and science-based model each patient is assessed as an individual and a personalised plan is created. The underlying ethos of our centre is based on food as medicine, and we are passionate about helping you to optimise your health through enjoying a nutritious and delicious diet.

It's not only what you eat that is important, our gut microbiome, genetics, lifestyle, and digestion is key to how we utilise the nutrients in our food and with our expert nutritional practitioner you can get to the root of any digestive issues or health complaints. We use functional medicine testing from Genova, Invivo and Regenerus and offer gut microbiome, SIBO, genetic, food allergy and nutritional status testing. Utilising dietary changes as our main form of nutritional therapy, Nathalie, Jane, Kate and Arabella can also prescribe a personalised plan of nutritional supplements if needed to assist with treatments and these are available from our dispensary or onsite shop, or we are happy to support you in purchasing them elsewhere.

Based on our family farm and in the rural county of Lincolnshire we are passionate about food, farming and our connection to where our food comes from. We use science and detailed understanding of each patient’s medical history, genetics, biochemical and lifestyle factors to create a personalised treatment plan which suits your lifestyle and budget. Our nutritional team can support you through making these changes, one step at a time, helping you to gain a love of healthy eating and the energy and vibrancy it can bring.
