Concerns: Significant challenges with communication, behaviour, social interaction, mood, and anxiety in a non-verbal 4-year-old with potential ASD.

“Over the past year we have seen our son develop and grow in ways that I do not think would have been possible without Josie and the Key Clinic.

Thank you for the amazing service you provide, enabling us to see our children
a happier and healthier version of themselves.”

Concerns: Challenges with anxiety, managing stress, and recurring depressive episodes.

"The Key Clinic Biomedical programme helped my teenage son with increased energy and improved mood.  Lilly was great at explaining which foods would benefit him and also how the supplements would help support him to feel better in himself. 

Lilly was always kind, positive and approachable and very easy for my son to talk to.  She gave him a sense of empowerment about his health which was great. He aged 17, she treated him like an adult which he appreciated and he had a good connection with her, which was vital for him to then take on board her advice.

I would take a long view as it's a long term programme and some days will be better and easier for your child to follow the programme than others, be mindful to not create more stress and any fear around food, if some days they don’t eat as healthily or some days they don’t take supplements, I would say in my experience it doesn’t mean the programme won’t work. My son continues to make healthier food choices than before and understands the importance of taking ongoing supplements.  So it becomes part of lifestyle rather than a temporary thing.
We are both very grateful for all of Lilly’s advice and support.”

Concerns: Challenges with fatigue, nausea, sleep, and emotional regulation in a 14-year-old girl.

“I heard about The Key Clinic from a podcast interview with the founder Sarah Warley and Liz Earle back in Oct 2021. (I would recommend listening to this).

My then 11-year-old (now 14) was struggling with fatigue and school attendance. Adding to the mix, emotions, anxiety and sleep, we just couldn’t get to the bottom of it. 3 years later after multiple trips to the doctor and leaving with an ADHD leaflet heading towards medication, we turned our attention
to a more holistic, getting-to-the-route-cause approach and contacted The Key Clinic.

For anyone considering the bio nutrition route, navigating the samples/test kits etc is a bit tricky initially but worth the outcome for a baseline to start the programme. It is a two-way commitment, and I cannot emphasise this enough, but once you find a rhythm it becomes part of a daily routine and I would like to say a huge “Thank you” to Josie Wareing who has guided us through the whole process.

As a family, we are in a much calmer place than this time last year, and I strongly believe Josie's input, knowledge, patience and relatability have been key.
We are now on a maintenance plan to tease out the fatigue elements and I would definitely recommend this programme for anyone who is struggling like we were.

Thank you to The Key Clinic and Josie Wareing.”

Programme: BioTransform

Concerns: Severe emotional dysregulation with anger/rage, aggression and property destruction, alongside low mood, mood swings, and anxiety.

“We can't thank the staff at the Key Clinic enough for all their help and support, in particular Josie, our Practitioner, who has been amazingly supportive. Before the start of treatment, we had a teenage son dealing with ADHD, alongside anger and challenging behaviour issues. We had all the tests, discussions etc and Josie came up with a specialised plan for us to work through. At times it has been a struggle to get him to participate, but Josie has gone above and beyond to help us as a family to overcome this. Throughout our programme, she has always checked how things are going and has amended the support plan as necessary. We now have a well-adjusted, much less angry teenage boy. The change in him is incredible. We can't thank Josie enough for all she has done.”

Programme: BioTransform

Concerns: Fatigue after activity, monthly digestive issues (particularly after high-carb meals) with gas and loose stools, and headaches associated with gut pain.

‘Our family has been with The Key Clinic for over a year, and my teenage son and I have had the pleasure of working with Bhavini. Her patience, attentive listening, and understanding of our family dynamic have been invaluable in helping us find a healthy way for my son to manage his ADHD. The deep insights she has provided into his well-being, along with the use of supplements, have not only improved his overall health but also positively influenced his mindset. It has been reassuring to know we are supporting him on the path to a happy and healthy adulthood. While The Key Clinic is an investment, I would highly recommend their services to anyone seeking a natural approach to health and well-being.”

Programme: BioTransform

Concerns: Severe skin issues, poor concentration, emotional dysregulation, anxiety, hyperactivity, sleep difficulties, digestive problems, and restrictive eating.

“Life changing support for angry 10 year old. We approached the Key Clinic on the recommendation of a friend and planned to do the work on retained reflexes for our 10 year old son, but it was recommneded that we try the BioMed programme with Maria first. Having been a complete skeptic about supplements and the importance of our gut biome, I am completely converted. Our son was volatile, angry and having toddler style meltdowns, and was unable to follow even simple instructions at home.

After the first few months (where we couldn't see any progress) about three months in the changes really started showing. He is now calm, responsible and almost completely self-sufficient. He is happier at school and finding it easier to make friends, and our home life is a lot more peaceful. He has also stopped having the frequent infections that had plagued him for the last three years (requiring antibiotics about 6 times a year).

Maria has been lovely - so supportive, and really listens to the feedback so we weren't having to force massive dietary changes on an already picky eater.”

October 2025

Programme: BioTransform

Concerns: Anger outbursts/meltdowns, high irritability, hyperactivity, sleep difficulties, separation anxiety, poor immune function with frequent infections, and digestive issues.

“Maria at the Key Clinic is absolutely fabulous! The whole process from start to finish was brilliant. My daughter is calmer, healthier and thriving, and that’s all thanks to Maria guiding me along the way through listening, good gut health, recipes and supplements.

Absolute game changer, Thank you Maria for all your help. I hope to follow up with maintenance check in’s soon! X”

Programme: BioTransform

Concerns: Difficulties with concentration, focus, and hyperactivity.

"We turned to Key Clinic for support with our 9-year-old son, and we couldn’t be happier with the care we’ve received. Our dietician, Rachel Beasley, has been incredibly knowledgeable and has the most wonderfully caring manner. What we’ve appreciated most is how she approaches every challenge from different angles, always working to find a solution that suits both us and our son. We can’t recommend Rachel and Key Clinic highly enough."

Concerns: Extreme sensitivity to clothing, poor immunity, and emotional dysregulation in a 10-year-old girl with ASD/SPD.

“We were so happy to discover Key Clinic after years of searching for ways to help our daughter with Sensory Processing Disorder and Autism. We have just finished a 6-month nutritional regime with amazing results. The biomedical report made us understand what our daughter’s body needs. The supplementation regime and personalised diet plan made her stronger and much more resilient. We now understand what she needs going forward. It was a real pleasure working with Josie who provided all the needed guidance as we progressed through the programme. Thank you Josie. You have made a profound difference to our daughter’s wellbeing and gave us so much hope.”

Programme: BioTransform

Concerns: Severe anxiety and difficulty coping with change.

“Having followed the Key Clinic gut biome programme for some 9 months, I am delighted to say that our daughter's anxiety levels are markedly decreased.

Josie has been wonderfully helpful and supportive right through the programme. Her advice and recommendations have definitely made a huge difference. Thank you.”

December 2025

Programme: BioTransform

Concerns: Severe sleep difficulties, fatigue, anxiety, poor mood regulation, concentration and focus issues, and hyperactivity, impacting mainstream schooling.

“From the very first Biomedical appointment, Josie, our bio-nutrient practitioner, was kind, patient and extremely knowledgeable. She took the time to get to know our son and had a good understanding of his needs and what, as parents, we wanted to address.
She supported us at every step, suggesting changes to treatment when needed, but not unnecessarily.

Our son has ADHD and struggled with anxiety, poor sleep and low mood; after some blood/urine tests, Josie was able to devise a programme of supplements that have supported any biochemical imbalances and addressed emotional dysregulation.

We had regular follow-up sessions to discuss improvements and any changes to treatment - there have been very positive changes for our son over the last year, and feel that this has been as a direct result of the expertise and care we received from Josie and the Key Clinic.”

Programme: BioTransform

Concern: Anger, Hyperactivity, Anxiety, and Emotional dysregulation

"Through the Key Clinic’s biomedical route, our son’s life has improved, and he is more stable, which in turn helps us all as a family. Through testing, we have discovered and been able to treat issues such as specific parasites and pyrrole disorder, which we had no idea of. I had been dabbling with numerous supplements before coming to the Key Clinic, never really knowing what was working and, at times, making things worse. Whilst there is still room for further gains for our complex son, we are in a much better place. Cynthia always shows a good understanding of our son, is professional, knowledgeable, kind, and always helpful. Thank you!"

Concern: Concentration, Energy, and Mood

"I felt quite hesitant at first when beginning the two pathways with The Key Clinic as I was unsure of what positive changes it could make to my life. I had to make a few changes to my lifestyle with my diet, implementing taking the prescription vitamins into my routine. Aga helped to make suggestions that could make these a lot easier to implement into my everyday life. In order to get the best results from the biomedical pathway, I really had to trust the process and listen to the suggestions that were made by Aga to aspects of my diet to help optimise the outcome. Alongside this, Aga taught us about the impacts of certain vitamin deficiencies and how that can have an impact on different aspects of my life, such as concentration, energy, and mood levels. As well as this, I also learnt how foods can influence and affect these aspects."

"All the changes made to my lifestyle were positive and have helped to improve my everyday life. It is definitely a commitment that you have to make for yourself, but I truly feel like a different person from the beginning of the biomedical treatment to the current day. I would highly recommend Aga Lemieszewska and The Key Clinic as it has made huge improvements to my life. I am really grateful for all of Aga's help, support, and guidance."

Concern: Anxiety, Anger, Sleep, Memory and Physical Wellbeing

"It’s been amazing working with you (Aga) and The Key Clinic has made it all very easy. I wasn’t the biggest fan of taking the supplements but I understood why I needed all of them and the programme has really helped me. I needed a big change in my life as I was heading in the wrong direction. Now everything’s much clearer and my symptoms such as anxiety, anger, memory, poor sleep, digestion, and acne have really improved or are no longer an issue. I’ve learned to eat better too and I move much more now, which is changing the way I look and feel for the better. I have learned so much about how my body works and what it needs, this will help me for the rest of my life - thank you so much Aga."

Programme: BioTransform

Concern: Anxiety, Gaming Habits, ADHD, Social Engagement

"Things are going well for my 19-year-old son; he is doing so much better. He has got a part-time job for the summer, which he is enjoying, he is getting up himself and getting ready, etc. He is regularly making meals for the family twice a week, he’s having weekly PT sessions at the gym, and he is joining in much more with family activities too."

"I feel so very grateful that he has made this progress. It has made life much better for our family. Thank you for all your help and advice."

Programme: BioTransform

Concern: ADHD, concentration and Eczema

"I contacted The Key Clinic looking for a non-medical way to manage my son’s ADHD and eczema, after hearing about Chris Evans’ positive experience with his son using The Key Clinic methods. Persuading a teenager to commit to the programme was tough, but the Key Clinic practitioner was very patient. The process has been fascinating and so informative. It has shown me just how powerful food and supplements can be, with a huge impact on ADHD symptoms, such as concentration, and eczema, which is almost gone now. Thank you so much for your guidance."

March 2024

Programme: BioTransform

Concern: Physical wellbeing, Low Mood, Anger, Emotional regulation, and Hypersensitivity

"We started at The Key Clinic 9 months ago. My 8-year-old’s symptoms included very low mood, anger issues, emotional dysregulation, hypersensitive hearing, and fatigue. My son had been a very happy toddler, but all of these symptoms had been getting worryingly worse as he got older. He would often be sent into the 'calm down' tent area of the classroom. We wanted to try and get him into another school but knew his current report about behaviour would work against him."

"I felt something was very biochemically imbalanced with my son, especially as he had had a lot of antibiotics in his life. Key Clinic testing showed a gluten and dairy intolerance, very low magnesium, pyrroles, high yeast, poor gut health, very low iron, low pancreatic enzymes, and very high mould toxins. He wasn’t digesting, absorbing, or eliminating properly; he was depleted in nutrients and was essentially very inflamed."

"Day 1 of the summer holidays, my son went gluten, dairy, and sugar-free, and we introduced supplements. Even though we ate pretty healthily, this was exceptionally hard work, and the withdrawal behavioural symptoms were awful. These were the very foods he sought out. However, it all paid off. He went back to school calmer, happier, and more regulated. The teachers assumed he had just matured over the summer. He got a good report, and he has now been accepted into a new school. Whilst we aren’t all the way there yet and there are still 'moments,' it is a far cry from where we were. We can clearly see a direct link between poor food choices and behaviour and mood. With the greatest thanks to Dr Zia Stratos and Anna Trundle for all their support. We will continue to have 6-monthly check-ins with The Key Clinic."

Concern: ADHD, Anxiety, Emotional Regulation, and Concentration

"We have just finished a 4-month biomedical programme with The Key Clinic, and it has changed our son’s and our lives for the better. Prior to contacting The Key Clinic, we were at a loss as to how to help our son Harry, who was going into year 11 at school. He had been suspended twice and was constantly in trouble for impulsive behaviour in the classroom. His emotional dysregulation was extreme and traumatic for the family; his mood was low, his anxiety high, and ADHD meds did not work for Harry."

"We entered the biomedical programme with a lot of hope. However, it took time and a lot of patience and support from the wonderful Aga to find the right balance of supplements for Harry. There were certainly times when we doubted the process and wondered if the supplements would really make a difference to Harry’s well-being. After a lot of adjustments to the protocol and tears from me, Harry seemed to be calm, happy, and emotionally regulated—something we hadn’t seen since he was 11 years old."

"Harry soon stopped his school counselling. His tutors reported an improvement in his concentration and focus, and at home, we started to see a young man who could plan and organise for himself, which was unheard of. There is still a way to go, but we can only say that the changes are beyond our wildest comprehension. Harry is now in a place where he will be able to ‘do life!’ We can’t thank Aga and the team enough for all that you have done, and we feel so privileged to have been able to travel this journey."

"I just had to share with you—Jacob has got Star of the Week this week! I can’t explain how proud we are of him. This week something just seems to have clicked, and he has been much happier. Thank you so much for everything."

Programme: BioTransform

Concern: Dyslexia, Emotional Regulation, Hypersensitivity, and Sleep

"Going ahead with The Key Clinic biomedical programme has been the best decision we've made for Tilly. We found that she was deficient in zinc, magnesium, and iron. Taking these supplements has massively improved her sleep, anger, and regulation of emotions. It's amazing what a difference taking these supplements can make."

"Our contact, Lilly, was extremely helpful and always on hand for questions. I would 100% recommend The Key Clinic."

September 2023

Programme: BioTransform

Concern: Sensory Processing, Hyper mobility, Coordination, Frustration, Impulse Control, and Emotional Regulation

"The Key Clinic’s biomedical programme has been life-altering for Tristan and indeed for the whole family. Within a matter of weeks of taking supplements, after discovering he was incredibly zinc deficient and had high copper levels, his attention, mood swings, even his balance, and social communication were vastly improved. He even started sleeping past 6 am, which had never happened in his life!"

"The before and after picture is like night and day, and I would highly recommend this to any parent with a child who struggles with any behavioural issues or neurodivergence. We had seen many specialists over the years, and not once had these deficiencies been picked up. I am forever grateful to Cynthia and the team for the support they have given us. Thank you so much."

June 2023

Programme: BioTransform

Concern: Dyspraxia, Autism, and Emotional Regulation

"We undertook the Biomedical Assessment and then completed a 4-month programme at The Key Clinic for our son, who has been struggling particularly with his emotional regulation. From the beginning, The Key Clinic practitioners were highly professional to deal with and extremely knowledgeable and supportive every step of the way."

"I would highly recommend this clinic if you want to see improvements in your child’s symptoms, whatever your child’s challenges are. It makes so much sense to test to see where their deficiencies lie, then treat these nutritionally and with tailor-made supplements as and where they are needed. There have been improvements in our son’s behaviour, and this will hopefully continue as he matures. It is good to know that we have hopefully corrected his chemical imbalances."

Additional Note: Although 4 months is a big commitment, it is worth doing to see the amazing results. A huge thank you to Lilly, who has been hugely kind and supportive throughout the programme.

Concern: Physical Wellbeing, Sleep, Fidgeting, Mood, and Anxiety

"I am so thankful for finding this company in 2020. Since completing the methylation programme, my physical and mental health has improved more than I could possibly have imagined, and I can work more too. I am medically complicated, and the testing showed issues that I can now confidently deal with."

"The staff are friendly and professional, and I highly recommend. Sending a huge thank you to the team!"

Programme: BioTransform

Concern: Emotional Regulation

"Sarah, you and your team are truly amazing! I totally share Liz Earle’s sentiment about getting quite emotional talking about what you do. It is nothing short of a miracle what you’ve achieved with our son over such a short time, and I know that we’ve really only just started. Can’t wait to see what happens next!"

"It’s staggering how little is really known and understood about all of this. Having seen our son wrongly medicated, I can really appreciate some of the more concerning stats about the consequences, as we’ve almost been there ourselves. I’m spreading the word as widely as I can!"

Programme: BioTransform

Concern: Anxiety and Emotional Regulation

"Renae’s been getting on great. She is coping far better at school, and her anxiety has been reduced considerably—some days, it’s non-existent. It’s had a huge positive impact on her day-to-day life and ours. She’s been able to participate in activities and even walk into class without being pulled off me. AMAZING. The improvement in Renae is truly remarkable, and I would love for you to share this with other families."

December 2020

Programme: BioTransform

Concern: Sleep, Processing Difficulties, Memory, and Anxiety

"Jack is doing great at the moment, and we've definitely seen general improvement in all areas. He’s sleeping like a king, trying many more foods, and is happy to try new things. His teachers have noticed that he’s retaining information more easily, and his anxiety isn’t crippling him anymore! It’s been wonderful to hear so many people comment on 'what a changed boy he is,' which is fantastic!"
