Just a few testimonials

“Keris looked at the whole picture, which was great and helped me see more clearly what was causing my issues now and long term. Since doing the gut protocol my fatigue and IBS symptoms are almost non-existent and any mild symptoms are easily kept at bay by continuing her lifestyle and food advice.”

Sarah | Fatigue and IBS

“Everyone wants to live longer, but to live longer you need to live better. With help you can turn your life around and make staying healthy your new habit. Keris doesn’t treat me as one of the thousands, we are working to a goal to make me better and I know we’ll get there. Oh and by the way, did I mention she’s practically saved my husband’s life too, after his heart attack. She helped us through the quagmire of eating right, supplements and day to day routines. She’s always there if we have a hiccup and ultimately, she cares. To anyone considering a 1:1 consultation you have nothing to lose and everything to gain!”

Lynne | Hypothyroidism (Hashimotos) 

“Keris is a unique practitioner. She joins the dots in a way that no other health professional else ever has. She has the ability to listen, digest and pull together information so she can offer suggestions that are achievable and effective. After spending a number of years baffled by my hormones and being diagnosed with premature ovarian insufficiency, I had blood tests results out of the blue that revealed pre-diabetes. I was so shocked as it was nothing I had ever considered could be an issue. I worked with Keris to understand what might be happening and to put a plan in place that was sustainable and balanced. I got my HBA1c from 42 (pre-diabetic) to 35 (healthy range) over this time. I can’t thank or recommend Keris enough!”

Rachael | Menopause and pre-diabetes

”My 1:1 Nutritional Therapy consultations with Keris have been invaluable to me, and I just don’t know where I would be if I had not invested in this. After in depth consultation and some diagnostic tests, Keris was able to pinpoint some of the key causes of my issues, and was able to devise a bespoke treatment protocol. I actually cried with relief! Within a few weeks of starting the protocol, my symptoms dramatically improved. I could function properly as a person again. For me, the best points about getting 1:1 Nutritional therapy is that it takes the guesswork out of the equation for you, and you hand all of that over to a qualified professional. To anyone who is considering 1:1 NT with Keris, I cannot recommend it enough. It’s the best investment you can make, you have to trust Keris (she really does know her stuff) and trust the process.”

Serji | Digestive health and prenatal nutrition

”I worked with Keris on a recent health scare that I had regarding high blood pressure. On the surface, this was a strange diagnosis for me as I eat healthily, exercise frequently and overall have a very high-quality lifestyle which felt in contrast to what I was seeing from the BP machine. My GP was leaning towards medication for the rest of my life which was an approach I was not particular keen on.

I met with Keris and she gathered a significant amount of information regarding my lifestyle and health. From this she was able to advise some ideas on things that I could try to that would improve by BP but without the need for medication.

During my time chatting with Keris, it was clear that she had an amazing amount of knowledge on the human body, what makes it work and in particular what can be done to improve things.

I have been able to take on and implement much of her advice and this has made a material impact on my BP, with the doctor expressing surprise at the amount of change I've been able to achieve in a short space of time.

I would recommend Keris to anyone seeking additional information on how to improve your health.”

Graham | High blood pressure

“I weaned myself off medication within 4 months of starting my new diet, got pregnant naturally within 6 months. I have two healthy daughters now and feel so much better educated about food choices.”

Agnieszka | Prenatal Nutrition Support

”I had been suffering with hypothyroidism for several years and getting nowhere fast so I decided to have a 1:1 consultation with Keris. It completely changed my life! I was tired despite sleeping a ridiculous amount of time, depressed, overweight, had terrible brain fog, and felt I had no purpose. Keris had pretty much worked it out from my blood test results and the in-depth medical/life history forms that I had Hashimotos. Keris has helped me find the right nutritional therapy to meet my needs and to make the right changes to my diet to help my autoimmune condition. At 56 I feel I am finally getting my life back. If you’re thinking of investing in a 1:1 with Keris I’d say do it – don’t put it off!”

Jane | Hypothyroidism (Hashimotos)

”I wanted to send you a quick email to say THANK YOU so much for all of your support. I am pleased to tell you that I have fully recovered, physically and emotionally, from being unwell last year, and I honestly don’t think I would be where I am today without your knowledge and support. I have returned to full time work, and to a varied and enjoyable exercise routine. I no longer have any gut discomfort whatsoever (which had been present for a few years), anxiety levels are much reduced, and my skin is really healthy. Your caring approach was exactly what I needed when I was at my lowest and I  cannot thank you enough for your time and expertise.”

Lauren | Digestive and Immune Support

”Working with Keris has so far felt really empowering. Having an expert guide through the overwhelming world of nutrition and hormones has not only helped me begin to uncover my intolerances and allow me to enjoy food in a way that no longer leads to pain and discomfort, but her approach is educational and she’s broken a complex topic down into phases that allow me to learn and understand my body. She’s also helping me push for diagnoses of long-term issues that I haven’t felt able to press for independently and I’m incredibly grateful for the support.”

Rebecca | IBS and hormone health

”I've been working with Keris for the past four years, seeking her guidance on a range of topics like digestion, managing anxiety, and fertility support.

Right from the start, Keris has been approachable and down-to-earth. Her practical approach, combined with her great sense of humour, has made working with her not only informative but also enjoyable!

What makes Keris stand out is her holistic approach to health. She doesn't just treat the symptoms; she digs deep to understand the root causes of issues. This approach has been a game-changer for me in improving my physical and mental well-being.

Over these four years, I've undergone a significant transformation in my eating and lifestyle habits. Initially, I was resistant to change, holding onto early morning HIIT classes, lots of coffee for a quick pick-me-up, fast food on the go, and never taking time to relax. This unhealthy routine led to constant fatigue and burnout.

But with Keris's guidance, over time I’ve learnt to adopt a more balanced and mindful approach. I've learned to listen to my body, prioritize more sleep, and enjoy homemade meals. These changes have boosted my energy levels and improved my overall health.

Working with Keris has been life-changing. Her expertise and unwavering support have empowered me to take charge of my health in ways I never thought possible. I wholeheartedly recommend her to anyone looking to make positive, lasting changes to their life through nutrition and lifestyle adjustments. Thanks to Keris, I've discovered the amazing benefits of these changes and found a path to a healthier, happier life..”

Julia | Digestive health, anxiety and fertility

”After 25 years suffering with IBS and getting minimal help from the NHS I took the plunge and booked in with Keris. We have been working together now for 6 weeks and I am so pleased I decided to do so. Keris immediately made me feel at ease and I have been impressed with both her knowledge and her compassion. To have this level of support has meant the difference between half-heartedly attempting random food exclusions on my own to following a structured plan of action which I feel I can keep to with Keris’s help. On top of the nutritional advice Keris has encouraged me to try methods to reduce anxiety and to keep in touch with my GP. I do feel this is worth every penny.”

Caroline | IBS and menopause support

”I was at a very low point, healthwise, when I was given the name of Keris Marsden as a nutritional therapist. Living in Europe, nutritional therapy is very different to the UK. I have found in Keris a perfect listening ear. In conjunction with my local GP, she was able to pinpoint what my body was lacking in nutritional supplements (something my GP knows very little of) and she also pointed out that my thyroid hormone was totally off balance. With her written explanation of what was needed, I approached the local endocrinologist who listened carefully to my story and has put me on a different hormone. Keris has a lot of practical knowledge, she has put me on the right track to regain my health and it's up to me to follow her advise and use her knowledge. I am 70 years old. I truly appreciate her input, her dedication and her enthusiasm about nutrition. I have learnt a lot”

Yvonne / Hypothyroidism

“I’ve worked with Keris on many occasions and still do to this day. Her knowledge is fantastic I could listen to her for ages. Keris always make me feel comfortable in my sessions. She has helped me with my skin improvement and gut health. And now has helped me through pregnancy, postpartum and breastfeeding ensuring I kept on top of my health throughout. Keris always has great recommendations on recipes, supplements and how to make the changes needed easy too. I always come away from our session full of confidence on how to make my next steps. She’s an absolute legend!👌🏼”

Zoe | Skin health, digestion and fertility

”Working with Keris has been transformational to my health journey. She has gone above and beyond to help me understand my current health whilst making both nutritional and lifestyle recommendations that have felt manageable for me. Keris’ passion shines through and I would recommend her to anyone embarking on improving their health.

Thank you Keris x.”

Lucy | Hormone imbalances, skin and IBS

”My daughter gifted me a consultation with Keris for Christmas, and what a brilliant gift it was. After my MOT at my doctors I was feeling rather down about myself, over weight high cholesterol just generally feeling tired and run down. We discussed my diet and how I could remedy my life style , touching on fitness and wellbeing. She sent me some recipes and I have set myself goals. They say you are what you eat. I feel so much better, more energy and I’ve lost weight..”

Dawn | High cholesterol

”'Keris has helped me and my family so much. My personal story involves a 10+ year long struggle with excruciating menstrual cramps. No doctor had mentioned the word endometriosis to be before. Keris spotted quickly that my list of symptoms could mean I have this condition. Keris helped me get a trans vaginal scan through the NHS, I have since gone private and had a diagnosis, this has helped me no end with my piece of mind.

As I mainly eat a vegan diet Keris has been great at recommending foods and supplements to make sure I do not have any deficiencies on a daily basis. As well as nutrition Keris has also advised on ways to increase my exercise due to the sedentary nature of my desk job. Keris provided me with easy to follow meal plans, with ideas for all 3 meals and snacks. Keris is friendly, clear and kind. She is also very patient if I fall out of good habits. I would highly recommend working with Keris to anyone who is experiencing ongoing issues, or just wants to live a healthier lifestyle.' ”

Leonie| Hormonal issues

”The best thing about my experience was the highly personalised approach founded upon the wealth of knowledge that Keris possesses, that allowed me to take practical steps that have significantly improved my overall health and wellbeing.”

Anu | Digestive health and athletic performance

”I have spoken to Keris on and off over the last 10 years or so. She’s incredibly knowledgeable and has primarily been supporting me with gut health issues. Her advice has been invaluable to me in guiding me on how to manage my symptoms and keep me on track.”
