Nutritional Consultations

When you receive your results, it may be daunting to know what to do next. Our food intolerance test comes with a free 30-minute consultation with one of our Nutritional Therapists. Within this consultation, we will advise you on what foods to eliminate from your diet, and help you find great alternatives so you can still enjoy mealtimes without experiencing the symptoms that come with a food intolerance or allergy. All of our consultations are bespoke; we can align recommendations with pre-existing diets (e.g. vegetarian, vegan), and we can also help recommend supplements to heal the gut from the effects of your intolerance.
