The flyer’s lifestyle and a turbulent routine can take its toll; irregular sleep patterns, “on the go” diets and the physical effects of flying are just the beginning. Many clients come to us feeling exhausted, rundown and in discomfort, with negative consequences on their professional and personal lives.

Through thorough analysis and consultation we get to the root of the problem and create a tailored strategy to help restore your good health and vitality.

We offer DNAviation™, a unique DNA testing service that allows you to understand your natural tolerances and nutritional needs according to your genetic make-up.


DNA Test

a simple swab test kit is provided for use at home, whilst travelling or in clinic, which provides a saliva sample


a report is generated based on 45 genetic markers surrounding nutrition,which include the client’s tolerance to lactose, gluten, salt, caffeine, their ability to detoxify, and areas of deficiency including Omega 3s, and B and D vitamins



a consultation in person at the Harley Street Clinic or online via conference call is provided by a member of The Aviation Nutritionist team to discuss the results, and a tailored diet plan to fulfill the client’s specific needs based on this


Nutrigenetics, nutrigenomics and epigenetics are emerging sciences that are going to have a huge impact on the way we manage our health. The results of the DNAviation™ test are designed to provide an insight into your specific needs, which will never change, but can be addressed to a great extent through nutritional choices. DNAviation™ offers a chance to invest in personal knowledge about your body that can inform your decisions on how to fuel your body effectively, and provide a significant improvement in your quality of life and long term health and wellbeing.


This genetic test allows you to receive the test via post prior to your initial consultation with one of our therapists.

Extra individual SNP’s can be arranged depending on the individual's requirements and the genetic analysis profile taken.

Cost of the DNA tests are therefore on an individual basis.

Personalised Nutrition:

Sarah Anderson

Director of Nutritional Therapy

Initial appointments: (1hr)  £205

Follow up appointments: (45 min) £165


Corporate workshops and nutrition seminars are available on request at a pre arranged fee.

Payment: You will be invoiced at the time of booking your appointments and payment is made via IBAN/Bank Transfer before your consultation. Cancellation policy is strictly 48hrs or the full consultation cost will be charged.

Consultation Process

Before your first appointment you will be emailed a detailed health, nutrition and lifestyle questionnaire.

The initial consultation, which typically lasts 60 minutes, a detailed picture of your life story will be taken. This will include your health and family history, current health concerns, symptoms, diagnosis and treatment, as well as stress levels, psychological and emotional factors and dietary, exercise and lifestyle habits.

When it is appropriate, functional tests may be recommended. The results of these tests facilitate the development of a targeted and individualised nutritional programme and are invaluable tools for monitoring progress through the programme.

You may be asked to have a blood test prior to the consultation which can be arranged at one of our designated phlebotomy locations. Test kits can also be sent via post to ensure you can fit the testing into your busy schedules worldwide.

All our therapists are qualified and registered with the Complementary & Natural Healthcare Council (CNHC). By choosing nutritional therapist backed by the CNHC, you can be confident that they are properly trained, qualified and insured.

The principles of Functional Medicine are anchored by an unraveling of the core imbalances that underlie, or cause ill health. Rather than simply offering a treatment for the symptoms of a problem, it looks at the root causes that might come from the client’s environment, nutrition, genetic attributes, and even psychological state.


Functional Tests in Clinic

This clinical approach uses the client’s personal story as a key tool for integrating signs and symptoms, and ultimately diagnosis. Evidence of clinical imbalances are integrated into a comprehensive approach to improve both the client’s environmental inputs and their physiological function.

The Adrenal Stress Profile is a powerful and precise noninvasive salivary assay that evaluates bioactive levels of the body’s important stress hormones, cortisol and DHEA. This profile serves as a critical tool for uncovering biochemical imbalances underlying anxiety, depression, chronic fatigue, obesity, dysglycemia, and a host of other clinical conditions

ONE FMV™ nutritional test helps to give an understanding of individual diet and supplementation needs, and offers a personalized functional nutrition assessment covering Antioxidants, B Vitamins, Digestive Support, and Minerals.

Nutritional deficiencies can be a factor of many complex chronic conditions, and ONE FMV™ utilises an easy first-morning urine collection (called a first morning void) to provide nutritional recommendations based on a patient’s individual nutritional test results. Clinicians commonly use such nutritional testing to determine the nutritional deficiencies that are at the root of chronic conditions.
