Working with Jan has genuinely been life‑changing. When I first came to her, I was struggling with chronic reflux that had completely taken over my life. I was afraid to eat, but also afraid to make changes — because when you already feel vulnerable, change can feel overwhelming. From the very beginning, Jan met me with patience, compassion and a level of care I hadn’t experienced anywhere else.
She offered a free phone consultation to talk through the programme, and instead of pushing anything on me, she asked whether I felt ready to make a change. That moment set the tone for everything that followed. She was diligent, incredibly knowledgeable, and took a truly holistic approach to a problem that doctors had only ever tried to medicate. It turned out my symptoms were rooted in a yeast intolerance, and together we spent over three months gently and consistently working on my diet and supplements to rebalance my gut.
Jan gave me information and understanding that will stay with me for life. She supported me at my own pace — never pressuring, always emphasising self‑care and self‑compassion, especially on the days when it felt really hard. Her guidance didn’t just help me heal physically; it helped me rebuild trust in my body and confidence in myself. I'm forever grateful, and the fact that my sister is now working with Jan too says everything about the trust we have in her support.

Before I started I didn’t think I could be helped as I’ve suffered with the same symptoms for years. After taking a food intolerance test suggested by Jan I finally found out what I was intolerant to and hey presto a lot of my symptoms have disappeared. Whenever I needed advice Jan answered my questions quickly and I felt confident to carry on with certain supplements. I would recommend Jan to anyone. It is an expensive process and I’m lucky to have been able to afford it and it was money very well spent. I’ll definitely contact Jan again if necessary. Thank you for your help.

I did find it very hard to ask for help. Jan, would reach out to me and kept checking in with me.
Strategies changed as we progressed, so I'm at a good point and just need to keep up with the new routine.

Jan absolutely knows her stuff!
When I began this journey last year I was a shadow of my current self. So unwell and had given up on recovery. Was recommended Jan by a Facebook friend from a support group I'm part of called Deaf to Menieres. I was in a chronic flare up of Menieres, and it wasn't fun. Jan was extremely familiar with every one of my symptoms and could instantly advise on ways to address each and every one.
I can not recommend Jan highly enough. It may seem expensive but honestly, it's worth every penny!

I wish I met Jan 15 years ago. I have hopped from numerous Functional Alternative Meds therapists, and by far, Jan got what I was suffering from and managed to get me to almost 100%. Its been a journey but Jan has been there for me every step of the way, using her knowledge and experience to diagnose the problem and treat with natural solutions where possible. Jan is great at listening and having patience with clients. I feel so much better after seeing here, and what I have realised is that plants and herbs are more effective than supplements in some cases, so I have decided to peruse the natural root after consulting with Jan. Thanks Jan for your wisdom, words of encouragement and knowledge, I am grateful. I would definitely recommend Jan to anybody suffering from health conditions where other practitoners have no answer.

We were so lucky to find Jan. She is open minded and approaches each individual's health concerns with such commitment.
Our experience of recovery from Mould illness has been very challenging, but Jan has guided us with confidence, which has given me hope in times when I have felt hopeless.
We are still on our journey of recovery, but knowing Jan is there when I need her support is a great comfort.

I have been working with Jan for the past 3 years to improve my health. Each new programme is well thought through following blood results. I feel healthier, have more energy, and a better upstanding of how important it is to have a varied, balanced diet.
Jan is supportive, kind and an inspiration.

Jan is an amazing nutritionist. I had stomach issues for about 5 years which was caused by breathing in mycotoxins. I have started her 6 month programme 3 months ago and I have been feeling a lot better. I'm 100% sure that all my problems will be solved once I complete her programme.

Jan’s nutritional advice has been invaluable to me over the years. As someone who struggles with stress and anxiety, I really value her holistic approach with emphasis on mind / body connection. Her explanations of what is happening physiologically in the body are really helpful in understanding the root cause of symptoms.
Jan has specifically helped me overcome issues in my reproductive system as well as boost my gut and digestive health and keep my immune system strong.
I also really value the fact that through Jan, clients can get a discount with the ‘Natural Dispensary’ who deliver very good quality supplements direct to your door.

I have been working with Jan now for a number of years and she has helped me enormously in the understanding of the condition I suffer from which is Menieres Disease. Jan has in that time identified a number of solutions to help relieve my symptoms.
Jan has done a significant amount of research into Menieres Disease cause and treatment and as a result has been able to develop a number of protocols to manage the multiple and varied symptoms I have encountered with this condition.
I have experienced significant improvement in my day to day health whilst working with Jan and she has always demonstrated great attention to detail to ensure all suggested solutions are safe and thoroughly researched .
Hence I would not hesitate to recommend Jan as a caring, responsible and successful practitioner who consistently achieves positive outcomes.

Jan's health programme has been very beneficial for addressing my health problems. She pointed out possible triggers and helped me address them step by step with a new health plan each step of the way. I can definitely recommend Jan's one on one health programme for improving your health.

With Jan’s help I have transformed my health. Her 1 : 1 programme is brilliant. I learnt so much that helped my diet but plan included so many wellness suggestions that have enhanced my life

Outstanding Advice and Support
I originally consulted with Jan on a nutrition plan post a health check. But I quickly discovered that she offers so much more than advice on diet, offering brilliant insights into a host of other lifestyle issues. For example, as a runner, I found her advice on overcoming sports injuries incredibly valuable. Jan's meal plans and advice are easy to follow and suggested recipes are delicious as well as nutritious. She is very clear is explaining the reasons behind the plan and is obviously someone who keeps up to date with the latest science and medical opinion.
On a personal note, she's incredibly warm, supportive and open. I looked forward to our 121 sessions.
For anyone looking to make positive changes to their health and lifestyle I can't recommend Jan highly enough.

My experience with Jan has been second to none. I developed a debilitating vestibular disease called Meniers Disease. I felt like my life was over. I couldn’t work, provide for my family or even take care of my family. I was in bed with dizziness, vertigo, ear symptoms and headache for over a year. Jan never gave up on me and only after a few sessions got me back on my feet and on the road to complete recovery.

It was an awful disease to be diagnosed with, I had no cure-able help from Doctors or specialist, waiting times of a year to see any of them, I was in deep trouble, alone, suffering with no outside help from anyone, the system had completely failed me, I started to look elsewhere, research brought me to a fabulous Meneries website by John Ingram, there Jan give free lectures and advice about this disease, I signed up to her consultancy immediately, I haven’t regretted it since, call it luck, destiny, whatever you like, she helped me understand in a very, scientific, knowledgable way what was going on with my body, she gave me confidence to try an alternative way in tackling this illness, it was hard at times but she was there.
A breakthrough recently came, all credit to Jans constant research, keeping up with groundbreaking cures by lending Doctors and Professors, something I would have never been privy to unless I was in contact with her, It’s helped greatly, I’m so grateful Jan.

I came to Jan having been told by medical professionals that there was nothing I could do with the arthritis in my foot. She worked with me very professionally, open and honest. Also changing my food habits in a way that was sustainable long term and completely removing the pain in my foot. Enabling me to go back to my sport, something I previously had struggled with due to the pain. I have since referred back to Jan for various advice and information on other aspects, again she is extremely knowledgeable and prompt with her replies.

I've learned such a lot from her this year !! 👍

I have worked with Jan many times over the years and she has given me so much good advice, which has lead to a really great improvement in my eating habits. It takes time to integrate these improvements but I have found that I feel much better as a result of making this effort.
I have found Jan to be very knowledgeable, caring, professional and helpful and puts in so much effort to help you. Nothing is too much trouble. I wouldn't hesitate to recommend Jan to anyone who is serious about changing their eating habits in order to feel better
