About me

Are you looking for guidance and support to understand why you are not feeling 100%?

As a Registered Nutritional Therapist in Braintree, Essex, I am able to work with individuals to help them make sense of their diets, improve overall health and well being, aiding them in feeling healthier and more energetic with better sleep, and small aches and niggles disappearing. Every body is unique with each body's systems working slightly differently, needing more or less of a particular vitamin, suiting a particular exercise type or having different sleep requirements.

For those with specific symptoms I follow the Functional Medicine model to assess and identify potential nutritional imbalances to address the root cause of symptoms, rather than offering symptom relief. I am qualified in using diagnostic testing that may be used to investigate underlying causes of symptoms. I may also recommend specific supplements for short term use.

Conditions that I have supported clients with include:

  • Digestion
  • Hormones - thyroid, PMS, adrenal
  • Fatigue
  • Auto-immune conditions
  • Musculo-skeletal support
  • MCS
  • Alzheimer's Disease
  • Sports nutrition
  • Weight - both difficulties losing and gaining weight
  • Food intolerances
  • Student nutrition - advising students how to eat well on a budget whilst away from home

I see clients on a one-to-one basis motivating them to achieve their health goals. Nutritional programmes are planned in collaboration with the client to ensure that they are realistic, practical and effective.

I have seen the difference correct, personalised nutrition made to the health of my own children and I am passionate about helping others achieve the same benefits of a good diet and healthy lifestyle.

I love helping people to make changes to their diet that ultimately results in positive changes to their health and wellbeing. I love seeing clients make real progress.

I also give talks to groups, gyms and schools including talks to Duke of Edinburgh Award groups to assist them in food planning for their expeditions.

Testing may be used to investigate underlying causes of symptoms. Tests may include: saliva, blood, hair and stool as well as food intolerance testing. Supplementation may be recommended for a short period to correct deficiencies and support the body whilst dietary changes are being made.

I am committed to furthering my knowledge in the field of nutrition and health and I regularly attend workshops and seminars, which have included:

  • Low FODMAP's Diet
  • Microbiome and gut health.
  • Impact gluten sensitivity
  • Metabolic syndrome and weight
  • Sports nutrition
  • Brain Health Programme - Alzheimer's Disease prevention
  • Adrenal and thyroid health
  • Stress
  • NLP for therapists
  • Nutrigenomics and health

Recent testimonials

"Thank you for making nutrition interesting!" - Comment from an attendee at a workshop

“I had been diagnosed with low bone density and needed help to change my eating habits. I had two appointments with Jennifer. We talked about my lifestyle and what I needed to change in order to achieve a healthy balanced diet for my bone density. She introduced me to specialised exercises for bone strength and the correct supplements that my diet was lacking. I have gradually changed some bad eating habits and implemented more of her suggestions for my health and wellbeing. I would highly recommend a visit to Jennifer for her expertise in this field”

“For years I have suffered around my 'time of the month' and my New Years resolution this year was to DO something about it, though I wasn't quite sure what. The results have been truly life changing! I had a very thorough consultation with Jen, who was fantastic. She really listened to what my issues were and provided me with clear guidance on tweaks I could make in my diet to make a difference........I cannot recommend Jen enough, she really REALLY knows her stuff! Thanks Jen!”

If a nutritionist's premises aren't step-free, they may offer alternative services such as telephone/web-based appointments, home visits, or meeting clients in different location, so you can choose the option that suits you best.

You can contact the nutritionist to discuss the options available.
