Terms of Engagement

Nutritional therapy is described as the application of nutrition science in order to promote individual care, health and optimal performance. 

It is today recognised as a complementary medicine and can be beneficial and relevant both for individuals with chronic conditions and individuals whose main aim is to reach optimal health and enhance performance.

As a Nutritional Therapist all individuals are treated as unique and the nutrition and lifestyle recommendations given will be tailored and personalised to each individual. Using a wide range of tools to investigate and identify potential nutritional and bodily imbalances and can help better understand and get to the root cause of an individuals health concern's and symptoms.

Practitioners never recommend nutritional therapy as a replacement for medical advice and always refer any client with 'red flag' signs or symptoms to their medical professional. They will also frequently work alongside a medical professional and will communicate with other healthcare professionals involved in the client's care to explain any nutritional therapy programme that has been provided.

Jessica Kanerva Ltd requests that the client notes the following: 


• The degree of benefit obtainable from Jessica Kanerva Ltd may vary between clients with similar health problems and following a similar programme.

• Nutritional advice will be tailored to support health conditions and/or health concerns identified and agreed between both parties.

• Nutritional therapists are not permitted to diagnose, or claim to treat medical conditions.

• Nutritional advice is not a substitute for professional medical advice and/or treatment and a Nutritional Therapist will never advice you to discontinue or amend any medications prescribed by your GP.

• Your Nutritional Therapist may recommend food supplements and/or functional testing as part of your Nutritional Therapy programme at an additional cost and may receive a commission on these products or services but these will not be recommended unless regarded as necessary.

• Standards of professional practice in Nutritional Therapy are governed by the CNHC Code of Conduct.​


The client understands and agrees to the following: 

• I (the client) am responsible for contacting my GP about any health concerns.

• If I (the client) am receiving treatment from my GP, or any other medical provider, you should tell him/her about any nutritional strategy provided by a nutritional therapist. This is necessary because of any possible reaction between medication and the nutritional programme.

• It is important that you tell your nutritional therapist about any medical diagnosis, medication, herbal medicine, or food supplements you are taking as this may affect the nutritional programme.

• If you are unclear about the agreed nutritional therapy programme/food supplement doses/time period, you should contact your nutritional therapist promptly for clarification.

• I (the client) understand that the advice is personal to me and may not be appropriate for others.

• You must contact your nutritional therapist should you wish to continue any specified supplement programme for longer than the original agreed period, to avoid any potential adverse reactions.

• You are advised to report any concerns about Nutritional Therapy promptly to your nutritional therapist for discussion and action.

• Recording consultations using any form of electronic media is not allowed without the written permission of both the Nutritional Therapist and the Client.

• I (the client) understand that all information discussed during consultations is strictly confidential but if the therapist feels there is an immediate danger to your life they will pass on your information onto an appropriate authority (such as the police, social services in the case of a child or a vulnerable adult, or GP in case of self-harm) using the legal basis of vital interests.
