Vitamin Bottles 3When I started building this website I looked carefully at the latest research into EDS as I wanted the information on the site to be as accurate as possible. I read many medical papers, some of them very interesting, some rather dull, but there was only one paper that really stuck in my mind. The paper proposes a simple treatment for EDS which might prevent symptoms getting worse and could even improve them, and it isn’t based on stem cells or gene therapy or any such advances which might not bear fruit for many years. The idea is based on nutritional supplements, which are widely available without prescription. You probably have some in your home already.
The paper is titled ‘A Novel Therapeutic Strategy for Ehlers-Danlos Syndrome based on Nutritional Supplements’. It was published in 2005, by Dr D. Mantle, Dr R.M. Wilkins and Professor V. Preedy. You can read the paper in full, for free, by clicking HERE.
The strategy is based on:
1, Increasing scientific evidence that nutrition may be a major factor in the development of many disorders once thought to result from defective genes alone.
2, The recognition that many of the symptoms associated with Ehlers-Danlos Syndrome are also characteristic of nutritional deficiencies.
3, The combined effect within the body of appropriate nutritional supplements in promoting normal tissue function.
The authors of the paper formed this hypothesis:
‘The symptoms associated with Ehlers-Danlos Syndrome may be successfully alleviated using a specific (and potentially synergistic) combination of nutritional supplements… at dosages which have previously been demonstrated to be effective against common symptoms of EDS in other disorders.’


  • The paper discusses the wide variety of essential nutrients which are required to maintain normal functioning of the body and how they are obtained. It mentions the poor nature of the modern diet and the depletion of nutrients in fruit and vegetables over the last 70 years.
  • It gives examples of common EDS symptoms which are also well established characteristics of nutritional deficiencies, such as susceptibility to bruising and bleeding (ie. deficiency in vitamin C / vitamin K) and mitral valve prolapse (ie. deficiency of magnesium and coenzyme Q10).
  • The paper mentions several reports of identical twins with connective tissue disorders with widely differing severity of symptoms, which the writers suggest indicates that disease progression can be influenced by environmental factors, the most likely of which is nutrition.
  • The paper argues that the current RDA (recommended daily allowance) for many nutrients is too low and patients would benefit from much higher intake of some vitamins and minerals.
  • The paper describes a number of precedents where the outcome of disease resulting from inherited disorders of metabolism can be improved by nutritional intervention. For example, folic acid supplements during pregnancy to prevent Spina Bifida.
  • The paper suggests a number of supplements could be helpful for patients with EDS and suggests doses. The supplements suggested include: vitamin C for wound healing, Methyl Sulphonyl Methane (MSM) and silica for bone and collagen formation, Pycnogenol (an anti-oxidant) for bleeding, Glucosamine for joint pain, Carnitine for muscle weakness, Coenzyme Q10 for mitral valve prolapse, Calcium for osteoporosis and Linolenic acidis for pain and inflammation.
In conclusion, the paper states that the combination of nutritional supplements they suggest are designed to counter the symptoms associated with EDS, namely skin and vascular problems, musculo-skeletal problems, cardiac mitral valve prolapse and periodontal disease.
The paper is interesting and persuasive, but could an effective treatment for EDS really be as simple as nutritional supplementation? I was very intrigued by the paper, so I started taking it to hospital clinic appointments to ask my doctors view of the idea. I was expecting a negative possibly even dismissive response, but every doctor I showed the paper to responded positively. I can’t give his name online but one doctor described Professor Victor Preedy, one of the writers of the paper, as ‘Very well known and respected’. So I decided to write to Professor Preedy and his co-authors. I was very interested to know if the nutrition supplement strategy had ever been clinically tested, and what the outcome was.
Unfortunately I have been unable to contact Professor Preedy. At the time the paper was written he was working in the Department of Nutrition and Dietetics at Kings College London. Professor Preedy may now have retired. However I have received responses from his co-authors. Dr Richard Wilkins was working in the School of Biology at Newcastle University when the paper was written. Dr Wilkins is now retired, but commented that he is unaware if a clinical study has ever taken place, and added that “Our approach in our earlier work was to explore the biological mechanisms and potential of medicinal plants (especially those with anti-oxidants) rather than evaluate clinical aspects.”
Dr David Mantle was working for Pharma Nord (UK) ‘a manufactuerer of dietary supplements and natural medicine for prevention’ at the time the paper was written, and is still employed by the company. Dr Mantle stated that no clinical study of the supplement strategy was carried out, but made a number of very helpful comments:
“The Medical Hypotheses paper is self-explanatory as to the rationale for the supplementation regime proposed, i.e. that supplements documented to provide significant symptomatic benefit in other disorders (e.g. glucosamine for joint pain in osteoarthritis) may provide similar benefit at similar dosage for similar symptoms in EDS. A disadvantage of this approach is that because EDS has so many symptoms, this would involve patients taking a large number of tablets / capsules (at least 14) per day, as well as the monetary expense involved. On this basis it may be better for individuals to focus on their most problematic symptoms e.g. glucosamine / chondroitin / MSM / silica for joint pain.”
“There is another way of looking at the issue of nutrition in EDS. Concerns are increasingly being raised about the potential problem of dietary deficiencies in the UK population as a whole, which presumably could also affect EDS patients, particularly those with gastrointestinal malabsorption issues. It has been estimated that more than 50% of the UK population are deficient in vitamin D due to insufficient sunlight exposure. The question therefore arises that if an EDS patient has, for example, muscle weakness / pain or fatigue, how much of this is due to the underlying EDS disorder and how much to dietary deficiency? If EDS patients ensure they are taking adequate amounts of these nutrients, they can at least ensure that their symptoms do not result from dietary deficiency. ”
“The next issue is whether nutritional supplementation at high levels might benefit symptoms caused by the underlying EDS, as opposed to dietary deficiency as above. For example, the recommended daily intake of vitamin C to prevent dietary deficiency is 60mg per day, whether vitamin C intake at higher doses (e.g. 750mg per day) may boost collagen production in EDS is open to question. There have been no documented clinical trials to date, but there have been a few case reports that high dose vitamin C can improve the clinical status of patients with impaired lysyl hydroxylase activity.” (ref) (ref) (ref) (ref).
“Gastrointestinal complications associated with Ehlers-Danlos syndrome are common and also need to be considered. These typically include abnormalities of smell or taste, difficulty chewing or swallowing, abnormal gastric or intestinal transit times and intestinal malabsorption. In particular, malabsorption resulting from collagen related structural defects of the small intestine may exacerbate deficiencies of key nutrients in the normal diet in Ehlers-Danlos patients. These problems may be compounded by physical difficulties in preparing nutritious meals or outdoor access (potentially leading to lack of vitamin D). Ehlers-Danlos patients deficient in recommended nutrients (which can be established via appropriate blood tests) may require significantly higher daily doses.”
“On a final note, the issue of product quality and bioavailabilty of nutritional supplements is often overlooked. Because supplements are not regulated in the same way as prescription medicines, levels of active substances may be deficient, and of poor bioavailabilty. Many clinical studies have undoubtedly failed because of this. To be effective, you should always choose a supplement manufactured to pharmaceutical standards, and with documented bioavailability.”
I have also sent the nutritional supplements paper to several doctors considered to be specialists in EDS to ask their view of the idea. To date I have only received one reply. I can’t give the doctors name online, but he/she described the paper as ‘Interesting, but untested’.

My Own Conclusion

No clinical research study has ever been performed to assess the possible benefits of nutritional supplements for people with EDS (ref). The Ehlers-Danlos National Foundation, the largest EDS charity, recommend EDS patients take 2-4 grams of vitamin C per day. They comment ‘We find that ascorbic acid (vitamin C) is a big help with the bruising and in many cases, has improved wound healing and muscular strength. Recently, we have learned in the laboratory, that Vitamin C instructs the body to make collagen.’ (ref). EDNF also gives advice about the importance of magnesium via their Professional Advisory Network (ref). So EDNF agree, at least in part, with the strategy in the paper, ie. that nutrition supplements could be beneficial. An article by Dr Nigel Burrows on the Ehlers-Danlos Support UK website discusses the use of vitamin C, but stops short of recommending it due to the lack of scientific testing (ref).
There is cutting edge research being done into treatments for Ehlers-Danlos Syndrome, but the simple idea of nutritional supplements appears to have been largely overlooked. This seems to be a shame. Nutritional supplements are widely available, relatively inexpensive and well tolerated. There are persuasive arguments they could be of real benefit to people with EDS, but we have no clinically obtained data to base decisions on.
My aim in writing this article is not to encourage everyone with EDS to start taking numerous supplements every day. Instead I want to draw attention to this simple idea and hopefully encourage someone or some organisation to clinically assess the strategy. I will be sending copies of this article to EDS charities, relevant doctors and hospitals. I will update this article with any progress!
Please remember I am not a doctor.
