" I began receiving Vitamin C infusions twice weekly in early December 2018, when I was at my weakest since my cancer diagnosis.


Almost immediately I began to notice the benefits of Vitamin C with a remarkable increase in energy levels as well as an improvement in my sleep. 


It drastically reduced the side effects of my chemotherapy treatment in terms of fatigue, nausea, brain fog, lack of appetite etc.


Within a couple of weeks, I found myself out walking, doing housework, driving, socialising and really starting to enjoy life again.


The standard of care at Dr. Stewart’s clinic is exceptional and the atmosphere is always inviting and relaxing. 

At the minute, I feel the happiest and healthiest than I ever have, with tonnes of energy and minimal side effects from conventional treatment.


Vitamin C has been truly transformative for me and for anyone diagnosed with cancer, I couldn't recommend it enough."

" I have been going to Dr Stewart for Vitamin C infusions since February 2018. I had been given between 6 to 12 months to live in January 2018, and I was desperate to find anything that would help to keep me alive. 

I had carried out lots of research into complementary therapies such as Vitamin C, and Hyperbaric Oxygen Therapy that I was convinced would help to prevent my cancer from spreading while I was waiting to get started on a clinical trial.

Since I started on Vitamin C I have had increased energy, a better quality of life with a get up and go that I haven't had since I was re-diagnosed. When I started on my immunotherapy treatment in April, I have continued with bi-monthly infusions.

The Vitamin C infusions have helped to offset the side effects of my treatment and to continue giving my general health and well being a much needed boost. 

I firmly believe that in the period when I was not on any treatment for my cancer, a period of about 14 weeks, the Vitamin C infusions helped to keep my cancer contained. 

I would highly recommend Vitamin C infusions for any cancer patient as an adjunct to their medical treatment, to offset side effects of treatment, particularly from chemotherapy, and also to give patients an energy boost and their immune systems a boost to help them fight off infection.

Dr Stewart and his team provide a warm, welcoming environment, where patients can relax in comfort and where patients will meet other like-minded individuals who are a great source of support to each other. 

I continue to attend for treatment on a weekly basis and will continue to do so while I am being treated for cancer. "

Dr G and Vicky.

I had major surgery in October 2017 for Stage IV Endometrial cancer. I undertook one treatment of Chemotherapy in December 2017, which resulted in complications requiring hospitalization for repeated infection, blood transfusions and eventually further surgery in January 2018

During this time I had no energy, no quality of life and lost 90% of my hair.


I came to see Dr Stewart in February 2018 and was very thankful when he agreed to take me on as a client. 

I have been receiving Vitamin C infusions since then and have experienced increased energy, vitality and well being. 

My quality of life has improved immensely. 

I enjoyed a summer holiday abroad with my family and have a full head of hair again.


Dr Stewart and his lovely staff provide an area of calm and comfort where I am confident that my treatments are doing me the world of good.

I understand that there are no guarantees of remission with any form of treatment but I am delighted to have found Dr Stewart.


I wish him continued health and strength, that he may continue his excellent work.

God bless him.

"In April 2013 I had an operation to remove what was thought to be a low-grade tumor. I was devastated to learn that I had aggressive high-grade cancer. And the tumor had begun to spread.


The surgeon told me there was only a 10% chance he got it all. All of the consultants agreed my only option was a huge operation involving removal of a large number of my organs and a 50% survival rate. I was also told if I did not do the surgery I would be dead within 1 to 2 years.


Faced with such a horrendous choice I did my own research and decided to choose non-conventional treatment-intravenous high dose Vitamin C, an intensive supplemental program, and a raw plant-based, no sugar diet.


The remarkable treatment at Dr Stewarts Clinic provided me with all the expert knowledge, treatment and support I needed. The clinic is like a 'home away from home', an oasis from the torment I was going through. And the treatments were painless and relaxing.

Dr Stewart saved my life.


I am cancer free, and have never felt or looked better. While the initial surgery to 'debulk' the tumor was invaluable, without the input of Dr. Stewart and his team I would either be dead or have very poor quality of life"

" Having spent about 23 years in the pharmaceutical industry, I tended not to pay much attention to an anecdotal evidence. However, when I was a young man with 3 young children I was diagnosed initially as having atrial fibrillation (the most common sustained cardiac arrhythmia), an irregular heartbeat, and heart failure (which my cardiologist at the time thought was caused by viral cardiomyopathy). At the time I used to get out of breath with minimal exertion e.g. walking up a flight of stairs. My prognosis was not good and I ended up in intensive care on two occasions as a result of chest infections which exacerbated my condition.

A few years later, I changed my cardiologist to one based closer to my home. He performed an angiogram on me and diagnosed coronary heart disease affecting some of my smaller coronary arteries. During this procedure I nearly died and had to receive cardio version. In a subsequent routine consultation with my cardiologist (who knew I worked in the pharmaceutical industry), he mentioned chelation therapy to me and said that I had probably heard about it but that I shouldn’t waste my money on it. In fact, I hadn’t heard about it and it went completely out of my mind until a few weeks later when I was browsing in the health section of Hodges Figgis bookshop. A book on chelation caught my eyes. I picked it up, read a few pages and decided to buy it. Having read it, I did a considerable amount of research on chelation therapy and decided it might be worth a try.

An outcome of my research was discovering that Dr. Gabriel Stewart practised intraveneous chelation therapy in Castleknock. At the time, I was still fairly skeptical. However, I decided to phone Dr. Stewart for a chat and asked him if I could speak to one of his patients who had received chelation therapy and had found it beneficial. Such a patient was having chelation in Dr. Stewart’s clinic at the time and Dr. Stewart arranged for me to speak to him. The ‘before and after’ story which this patient told me was so remarkable that I decided there and then to give chelation a try. Several years have passed since then and I have had many chelation treatments administered by Dr. Stewart and his very competent and caring nurses. After I had a considerable number of chelation treatments, family, friends, and colleagues began to tell me how well I looked (compared to how I used to look). A friend who I hadn’t seen for a long time was quite astonished by how well I looked because when she had met me quite a long time previously she thought I looked very ill. In fact, to my shock, she said that she was surprised I was still alive!


Over the years of attending Dr. Stewart’s clinic, I have talked to many fellow patients in the clinic, some of whom have shared other remarkable ‘before and after’ stories with me in relation to their positive experiences with chelation under Dr. Stewart. These ‘before and after’ stories included: (a) An elderly man told me that he had an angiogram which indicated that he had significant blockages in his coronary arteries. Without telling his cardiologist, he decided to have intravenous chelation therapy. Following a course of chelation therapy, he had another angiogram and his cardiologist told him his coronary arteries were clear, (b) A middle aged lady told me that she enjoyed going hill walking but had to give it up because she developed unstable angina. Following a course of chelation therapy, she was able to return to hill walking, (c) A middle aged man told me that he had a positive cardiac stress test (i.e. changes on his ECG indicated a low oxygen supply to his heart muscle). After a course of chelation therapy, he had a repeat cardiac stress test and the result was negative (normal), (d) A middle aged gentleman (a doctor) told me that like myself, he had to retire early due to a heart problem. However, after a course of intravenous chelation therapy he felt very much better and returned to work.

I will soon be 62 years old and I feel healthier now than I did 20 years ago. I returned to work 6 years ago having previously decided to retire when I was 50 due to my poor health. For over 2 years now I have been working out by doing weight training 3 to 4 times per week. I also swim on a regular basis as I am a former competitive swimmer. In addition to having chelation maintenance therapy I take a number of dietary supplements which Dr. Stewart recommended to me. A few weeks ago, I was on holiday in Nerja (Spain) and I decided to do an ‘experiment’. When I first visited Nerja 16 years ago, I had significant difficulty walking up a very considerable number of steep steps from the beach. I got very breathless and had to stop several times on route to get my breath. However, a few weeks ago, I walked up these very same steps without any difficulty whatsoever, without stopping, and being only slightly breathless when I got to the top.

I am fully aware that my account above is purely anecdotal evidence and that the vast majority of physicians and scientists would view it as dubious and unreliable. I fully understand their view, because as someone with a scientific background who worked in the pharmaceutical, surgical and medical devices sectors I would have shared the same view before I tried intravenous chelation therapy myself. If you have already carried out your own research on intravenous chelation therapy, and have decided to give it a try, I would highly recommend Dr. Stewart and his team to you. They are very caring and very competent professionals.

If you are currently in the process of carrying out your own research on chelation therapy, I would recommend you read a book titled ‘Bypassing Bypass Surgery’ by Dr. Elmer Cranton. Visit: http://www.amazon.co.uk/Bypassing-Bypass-Surgery-Chelation-Non-surgical/dp/1571742972/ref=sr_1_1?s=books&ie=UTF8&qid=1368630034&sr=1-1&keywords=Bypassing+bypass+surgery

I also recommend that you look at the Chelation Therapy section of Dr. Cranton’s website. Visit: http://www.drcranton.com "

"I first attended Dr Stewarts clinic in Castleknock in June 2005.I had By Pass surgery in 1998 and was now feeling unwell with shortness of breath on exertion, lack of energy and difficulty in keeping up a busy schedule. I was also on drugs for blood pressure and high cholesterol.   A friend of mine recommended Dr. Stewart in Castleknock and had my first chelation in July 2005.After a series of treatments

I felt much better and continue to attend Dr. Stewarts clinic for booster treatments over the past 8 years. I now eat a good diet and take supplements as recommended with no need for me to take drugs.
I have no problems in maintaining my busy schedule now and will be forever grateful to Dr Stewart ,His staff, and My friend for having advised me to go for chelation treatments .I would highly recommend that anyone with circulatory problems attend Dr. Stewart in Castleknock."



"I had 2 by cardiac by pass surgeries and was persistently short of breath with no energy. I read an article in the press about chelation and went for chelation to Dr .Stewarts clinic then in Churchtown. This was in April 2001.After a series of 30 treatments I felt 20 years younger with no further chest pains and able to walk long distances with no discomfort. I had no need for further by-pass surgery.
Since then I have continued to attend Dr. Stewarts clinic now in Castleknock and over 12 years later still feel benefits. I attend every three to four months for boosters and credit Intravenous EDTA chelation , Dr. Stewart and his wonderful staff with keeping me alive and healthy all these years."
