“Most of the supplement market is bogus,” Paul Clayton*, a nutritional scientist, told the Observer. “It’s not a good model when you have businesses selling products they don’t understand and cannot be proven to be effective in clinical trials. It has encouraged the development of a lot of products that have no other value than placebo – not to knock placebo, but I want more than hype and hope.” So, Dr Clayton took a job advising Lyma, a product which is currently being promoted as “the world’s first super supplement” at £199 for a one-month’s supply.

Lyma is a dietary supplement that contains a multitude of ingredients all of which are well known and available in many other supplements costing only a fraction of Lyma. The ingredients include:

  • kreatinin,
  • turmeric,
  • Ashwagandha,
  • citicoline,
  • lycopene,
  • vitamin D3.

Apparently, these ingredients are manufactured in special (and patented) ways to optimise their bioavailabity. According to the website, the ingredients of LYMA have all been clinically trialled with proven efficacy at levels provided within the LYMA supplement… Unless the ingredient has been clinically trialled, and peer reviewed there may be limited (if any) benefit to the body. LYMA’s revolutionary formulation is the most advanced and proven super supplement in the world, bringing together eight outstanding ingredients – seven of which are patented – to support health, wellbeing and beauty. Each ingredient has been selected for its efficacy, purity, quality, bioavailability, stability and ultimately, on the results of clinical studies.

The therapeutic claims made for the product are numerous:

  • it will improve your hair, skin and nails (80% improvement in skin smoothness, 30% increase in skin moisture, 17% increase in skin elasticity, 12% reduction in wrinkle depth, 47% increase in hair strength & 35% decrease in hair loss)
  • it will support energy levels in both the body and the brain (increase in brain membrane turnover by 26% and increase brain energy by 14%),
  • it will improve cognitive function,
  • it will enhance endurance (cardiorespiratory endurance increased by 13% compared to a placebo),
  • it will improve quality of life,
  • it will improve sleep (reducing insomnia by 70%),
  • it will improve immunity,
  • it will reduce inflammation,
  • it will improve your memory,
  • it will improve osteoporosis (reduce risk of osteoporosis by 37%).

These claims are backed up by 197 clinical trials, we are being told.

If true, this would be truly sensational – but is it true?

I asked the Lyma firm for the 197 original studies, and they very kindly sent me dozens papers which all referred to the single ingredients listed above. I emailed again and asked whether there are any studies of Lyma with all its ingredients in one supplement. Then I was told that they are ‘looking into a trial on the final Lyma formula‘.

I take this to mean that not a single trial of Lyma has been conducted. In this case, how do we be sure the mixture works? How can we know that the 197 studies have not been cherry-picked? How can we be sure that there are no interactions between the active constituents?

The response from Lyma quoted the above-mentioned Dr Paul Clayton stating this: “In regard to LYMA, clinical trials at this stage are not necessary. The whole point of LYMA is that each ingredient has already been extensively trialled, and validated. They have selected the best of the best ingredients, and amalgamated them; to enable consumers to take them all in a convenient format. You can quite easily go out and purchase all the ingredients separately. They aren’t easy to find, and it would mean swallowing up to 12 tablets and capsules a day; but the choice is always yours.”

It’s kind, to leave the choice to us, rather than forcing us to spend £199 each month on the world’s first super-supplement. Very kind indeed!

Having the choice, I might think again.

I might even assemble the world’s maximally evidence-based, extra super-supplement myself, one that is supported by many more than 197 peer-reviewed papers. To not directly compete with Lyma, I could use entirely different ingredients. Perhaps I should take the following five:

  • Vitamin C (it has over 61 000 Medline listed articles to its name),
  • Vitanin E (it has over 42 000 Medline listed articles to its name),
  • Collagen (it has over 210 000 Medline listed articles to its name),
  • Coffee (it has over 14 000 Medline listed articles to its name),
  • Aloe vera (it has over 3 000 Medline listed articles to its name).

I could then claim that my extra super-supplement is supported by some 300 000 scientific articles plus 1 000 clinical studies (I am confident I could cherry-pick 1 000 positive trials from the 300 000 papers). Consequently, I would not just charge £199 but £999 for a month’s supply.

But this would be wrong, misleading, even bogus!!!, I hear you object.

On the one hand, I agree.

On the other hand, as Paul Clayton rightly pointed out: Most of the supplement market is bogus.

 

 

 

 

*If my memory serves me right, I met Paul many years ago when he was a consultant for Boots (if my memory fails me, I might need to order some Lyma).

Oscillococcinum is by now well-known to readers of this blog, I am sure (see for instance here, here and here). It seems an important topic, not least because the infamous duck-placebo is the world’s best-selling homeopathic remedy. Just how popular it is was recently shown in a survey by the formidable ‘Office for Science and Society’ of the McGill University in Canada.

The researchers surveyed the five biggest pharmacy chains in Quebec: Jean-Coutu, Familiprix, Uniprix, Proxim, and Pharmaprix. For each chain, a sample of 30 pharmacies was chosen by a random number generator.

The calls started with the following script: “I would like to know if you carry a certain homeopathic remedy. It’s called Oscillococcinum, it’s a homeopathic remedy against the flu made by Boiron.” If they did not have it, the investigator asked if this was something they normally carried. He spoke to either a floor clerk or a member of the pharmacy staff behind the counter, depending on who knew the answer.

Out of the 150 pharmacies on the island of Montreal that were called for this investigation, 66% of them reported carrying Oscillococcinum (30% did not, while 4% could not be reached, often because the listed pharmacy had closed). Some chains were more likely to sell the product, with Jean-Coutu and Pharmaprix being the most likely (80% of their stores had it) and Proxim being the least likely (50% of their stores carried it).

The McGill researcher stated that the fact that two-thirds of Montreal-based pharmacies will sell us a pseudo-treatment for the flu that targets adults, children and infants alike is hard to square with the Quebec Order of Pharmacists’ mission statement. They describe said mission as “ensuring the protection of the public”, but how is the public protected when pharmacies are selling them placebo pills? The harm is partly financial: 30 doses of these worthless globules retail for CAD 36. It is also in the false sense of security parents will gain and the delay in proper treatment if needed. And, ultimately, it is in the legitimization of a pseudoscience the founding principle of which is that the more you add water to something (like alcohol), the more powerful it becomes.

I can only full-heartedly agree. One might even add a few more things, for instance that there are other dangers as well:

  1. If pharmacists put commercial gain before medical ethics, we might find it hard to trust this profession.
  2. If people take Oscillococcinum and their condition subsequently disappears (because of the self-limiting nature of the disease), they might believe that homeopathy is effective and consequently use it for much more serious conditions – with grave consequences, I hasten to add.
  3. If consumers thus start trusting homeopaths, they might also fall for some of their abominable health advice, e. g. that about not vaccinating their children.
  4. If a sufficiently large percentage of people believe in the magic of shaken water, our rationality will be undermined and we will encounter phenomena like Brexit or fascists as presidents (sorry, I has to get that off my chest).

Belgian homeopaths, together with the ‘European Committee for Homeopathy’, have published a statement which I find too remarkable to withhold it from you:

START OF QUOTE

Users of homeopathic medicines can no longer remain silent about the untruths circulating in the media. These lies raise doubts which naïve and gullible people take on board all too easily and then see homeopathy as quackery. None of this is accurate!

Because they fear seeing some of their ‘certainties’ questioned, the SKEPP movement is firing off at anything that current science cannot yet explain with both barrels.

The contents of homeopathic medicines
SKEPP states that a homeopathic medicine is nothing more than a drop of water in a swimming pool and therefore has nothing in it. This is  wrong. Tests performed on a high homeopathic potency (30CH) of Gelsemium sempervirens (Yellow Jasmine, a very common homeopathic medicine) have detected 36 micrograms of a specific substance per gram of solution [1]. Opponents denounce homeopathic medicines as being nothing but water. This is  wrong. This water, the solvent itself, contains a specific signature of the active ingredient. Basic research has demonstrated this [2].

Clinical efficacy.
By asserting at every opportunity that there is no evidence of the clinical effectiveness of homeopathy, opponents sow doubt. Correction:  such proof [3] does exist.  The fact that critics refuse to look at or accept these data speaks volumes about their attitude to science.
What is true, however, is that there is  not enough  scientific evidence of effectiveness. Science demands a lot of such evidence – and rightly so. There would be more if the universities applied the rules correctly!  For example: The Professional Union of Homeopathic Physicians had accepted a double-blind research protocol for fibromyalgia which took account of homeopathy’s individualized approach. This research was to be carried out at the Rheumatology Department of a hospital in Brussels with the agreement of the Rector of the Faculty of Medicine. But the hospital’s ethics committee decided that it would be unethical to test a ‘placebo’ (the homeopathic medicine) versus another placebo! Making an a priori assumption that homeopathic medicine is just a placebo, even before beginning the study, flies in the face of scientific objectivity.

Patients are not stupid!
In the meantime, Pro Homeopathia, the Belgian association of homeopathy patients, is no longer able to contain its members’ exasperation. It has published an article [4]  which denounces in direct terms the accusations of credulity, or even stupidity levelled at patients, in blatant disregard of their therapeutic freedom of choice and their capacity for critical thought.

Dare to ask questions! 
Why all this misinformation in the press? Why do these ‘experts’, whose opinions on homeopathy above all betray their profound misunderstanding of this discipline, flood the media with fake news? What is the hidden agenda behind this campaign of systematic denigration? Homeopathy and many other complementary medicines only want to collaborate, both in medical practice and in scientific research … fair play! It’s called integrative medicine!

END OF QUOTE

For regular readers of this blog, any comment on this little article might well be superfluous. For newcomers, I nevertheless provide a few thoughts. In doing so, I simply follow the three headings used above.

The contents of homeopathic medicines

A homeopathic C30 potency (the one that is used most frequently) is a dilution of 1 part homeopathic stock to 1000000000000000000000000000000000000000000000000000000000000 parts of diluent. This amounts to little more than one molecule of stock per universe. This is an undeniable fact, and the reference provided (incidentally, the link to it is dead) does not change it in any way. The theory of ‘the memory of water’ is an implausible hypothesis that has no basis in reality. It is believed only by homeopaths, and ‘studies’ that seemingly support it are flimsy, false or biased, and usually only get published in journals such as ‘Homeopathy’ (where also the reference provided appeared).

Clinical efficacy

This is a subject that we have already discussed ad nauseam. Highly diluted homeopathic remedies are pure placebos. If someone does not believe this nor all the evidence provided on this blog, they perhaps trust the many independent international bodies that have looked at the totality of the reliable evidence for or against homeopathy. Their verdicts are unanimously negative. (The above-cited decision of the ethics committee is therefore the only one that is ethically possible.)

Patients are not stupid!

That is absolutely correct; patients are certainly not stupid. And their experiences are certainly real. What is often wrong, however, is the interpretation of their experiences. When a patient’s symptoms improve after taking a highly diluted remedy, the perceived improvement is due to a long list of factors that are unrelated to the remedy: placebo, natural history, regression towards the mean, etc.

Patients are not stupid, but the misinformation homeopaths incessantly publish might render them stupid – one more reason why such irresponsible nonsense ought to stop.

 

Probiotics (live microorganisms for oral consumption) are undoubtedly popular, not least they are being cleverly promoted as a quasi panacea. But are they as safe as their manufacturers try to convince us? A synthesis and critical evaluation of the reports and series of cases on the infectious complications related to the ingestion of probiotics was aimed at finding out.

The authors extensive literature searches located 60 case reports and 7 case series including a total of 93 patients. Fungemia was the most common infectious complications with 35 (37.6%) cases. The genus Saccharomyces was the most frequent with 47 (50.6%) cases, followed by Lactobacillus, Bifidobacterium, Bacillus, Pedioccocus and Escherichia with 26 (27.9%), 12 (12.8%), 5 (5.4%), 2 (2.2%) and 1 (1.1%) case, respectively. Adults over 60 years of age, Clostridium difficile colitis, antibiotic use and Saccharomyces infections were associated with overall mortality. HIV infections, immunosuppressive drugs, solid organ transplantation, deep intravenous lines, enteral or parenteral nutrition were not associated with death.

The authors concluded that the use of probiotics cannot be considered risk-free and should be carefully evaluated for some patient groups.

Other authors have previously warned that individuals under neonatal stages and/or those with some clinical conditions including malignancies, leaky gut, diabetes mellitus, and post-organ transplant convalescence likely fail to reap the benefits of probiotics. Further exacerbating the conditions, some probiotic strains might take advantage of the weak immunity in these vulnerable groups and turn into opportunistic pathogens engendering life-threatening pneumonia, endocarditis, and sepsis. Moreover, the unregulated and rampant use of probiotics potentially carry the risk of plasmid-mediated antibiotic resistance transfer to the gut infectious pathogens. 

And yet another review had concluded that the adverse effects of probiotics were sepsis, fungemia and GI ischemia. Generally, critically ill patients in intensive care units, critically sick infants, postoperative and hospitalized patients and patients with immune-compromised complexity were the most at-risk populations. While the overwhelming existing evidence suggests that probiotics are safe, complete consideration of risk-benefit ratio before prescribing is recommended.

Proponents of probiotics will say that these risks are rare and confined to small groups of particularly vulnerable patients. This may well be so, but in view of the often uncertain benefits of probiotics, the incessant hype and aggressive marketing, I find it nevertheless important to keep these risks in mind.

As with any therapy, the question must be, does this treatment really generate more good than harm?

A few weeks ago, I was interviewed by a journalist who wanted to publish the result in a magazine. He now informed me that his editor decided against it, and the interview thus remained unpublished. I have the journalist’s permission to publish it here. The journalist who, in my view, was well-prepared (much better than most), prefers to remain unnamed.

Q: How would you describe yourself?

A: I am a researcher of alternative medicine.

Q: Not a critic of alternative medicine?

A: Primarily, I am a researcher; after all, I have published more Medline-listed research papers on the subject than anyone else on the planet.

Q: You are retired since a few years; why do you carry on working?

A: Mainly because I see a need for a critical voice amongst all the false and often dangerous claims made by proponents of alternative medicine. But also because I enjoy what I am doing. Since I retired, I can focus on the activities I like. There is nobody to tell me what to do and what not to do; the latter happened far too often when I was still head of my research unit.

Q: Fine, but I still do not quite understand what drives you. Who is motivating you to criticise alternative medicine?

A: Nobody. Some people claim I am paid for my current activities. This is not true. My blog actually costs me money. My books never return enough royalties to break even, considering the time they take to write. And for most of my lectures I don’t charge a penny.

Q: There are people who find this hard to believe.

A: I know. This just shows how money-orientated they are. Do they want me to publish my tax returns?

Q: Sorry, but I still don’t understand your motivation.

A: I guess what motivates me is a sense of responsibility, a somewhat naïve determination to do something good as a physician. I am one of the only – perhaps even THE only – scientist who has researched alternative medicine extensively and who is not a promoter of bogus therapies but voices criticism about them. There are several other prominent and excellent critics of alternative medicine, of course, but they all come ‘from the outside’. I come from the inside of the alternative medicine business. This probably gives me a special understanding of this field. In any case, I feel the responsibility to counter-balance all the nonsense that is being published on a daily basis.

Q: What’s your ultimate aim?

A: I want to create progress through educating people to think more critically.

Q: Which alternative medicine do you hate most?

A: I do not hate any of them. In fact, I still have more sympathy for them than might be apparent. For my blog, for instance, I constantly search for new research papers that are rigorous and show a positive result. The trouble is, there are so very few of those articles. But when I find one, I am delighted to report about it. No, I do not hate or despise any alternative medicine; I am in favour of good science, and I get irritated by poor research. And yes, I do dislike false claims that potentially harm consumers. And yes, I do dislike it when chiropractors or other charlatans defraud consumers by taking their money for endless series of useless interventions.

Q: I noticed you go on about the risks of alternative medicine. But surely, they are small compared to the risks of conventional healthcare, aren’t they?

A: That’s a big topic. To make it simple: alternative medicine is usually portrayed as risk-free. The truth, however, is that there are numerous risks of direct and indirect harm; the latter is usually much more important than the former. Crucially, the risk-free image is incongruent with reality. I want to redress this incongruence. And as to conventional medicine: sure, it can be much more harmful. But one always has to see this in relation to the proven benefit. Chemotherapy, for instance, can kill a cancer patient, but more likely it saves her life. Homeopathic remedies cannot kill you, but employed as an alternative to an effective cancer treatment, homeopathy will certainly kill you.

Q: Homeopathy seems to be your particular hobby horse.

A: Perhaps. This is because it exemplifies alternative medicine in several ways, and because I started my alternative ‘career’ in a homeopathic hospital, all those years ago.

Q: In what way is homeopathy exemplary?

A: Its axioms are implausible, like those of many other alternative modalities. The clinical evidence fails to support the claims, like with so many alternative therapies. And it is seemingly safe, yet can do a lot of harm, like so many other treatments.

Q: You have no qualification in homeopathy, is that right?

A: No, I have no such qualifications. And I never said so. When I want to tease homeopaths a little, I state that I am a trained homeopath; and that is entirely correct.

Q: In several countries, homeopathy has taken spectacular hits recently. Is that your doing?

A: No, I don’t think so. But I do hope that my work has inspired the many dedicated activists who are currently protesting against the reimbursement of homeopathy by the public purse in the UK, Germany, France, Spain, etc.

Q: You often refer to medical ethics; why is that?

A: Because, in the final analysis, many of the questions we already discussed are really ethical issues. And in alternative medicine, few people have so far given the ethical dimensions any consideration. I think ethics are central to alternative medicine, so much so that I co-authored an entire book on this topic this year.

Q: Any plans for the future?

A: Plenty.

Q: Can you tell me more?

A: I will publish another book in 2019 with Springer. It will be a critical evaluation of precisely 150 different alternative modalities. I am thinking of writing yet another book, but have not yet found a literary agent who wants to take me on. I have been offered a new professorship at a private University in Vienna, and am hesitant whether to accept or not. I have been invited to give a few lectures in 2019 and hope to receive more invitations. Last not least, I work almost every day on my blog.

Q: More than enough for a retiree, it seems. Thank you for your time.

A: My pleasure.

Many chiropractors tell new mothers that their child needs chiropractic adjustments because the birth is in their view a trauma for the new-born that causes subluxations of the baby’s spine. Without expert chiropractic intervention, they claim, the poor child risks serious developmental disorders.

This article (one of hundreds) explains it well: Birth trauma is often overlooked by doctors as the cause of chronic problems, and over time, as the child grows, it becomes a thought less considered. But the truth is that birth trauma is real, and the impact it can have on a mother or child needs to be addressed. Psychological therapy, physical therapy, chiropractic care, acupuncture, and other healing techniques should all be considered following an extremely difficult birth.

And another article makes it quite clear what intervention is required: Caesarian section or a delivery that required forceps or vacuum extraction procedures, in-utero constraint, an unusual presentation of the baby, and many more can cause an individual segment of the spine or a region to shift from its normal healthy alignment. This ‘shift’ in the spine is called a Subluxation, and it can happen immediately before, during, or after birth.

Thousands of advertisements try to persuade mothers to take their new-born babies to a chiropractor to get the problem sorted which chiropractors often call KISS (kinetic imbalance due to suboccipital strain-syndrome), caused by intrauterine-constraint or the traumas of birth.

This abundance of advertisements and promotional articles is in sharp contrast with the paucity of scientific evidence.

A review of 1993 concluded that birth trauma remains an underpublicized and, therefore, an undertreated problem. There is a need for further documentation and especially more studies directed toward prevention. In the meantime, manual treatment of birth trauma injuries to the neuromusculoskeletal system could be beneficial to many patients not now receiving such treatment, and it is well within the means of current practice in chiropractic and manual medicine.

A more critical assessment of … concluded that, given the absence of evidence of beneficial effects of spinal manipulation in infants and in view of its potential risks, manual therapy, chiropractic and osteopathy should not be used in infants with the kinetic imbalance due to suboccipital strain-syndrome, except within the context of randomised double-blind controlled trials.

So, what follows from all this?

How about this?

Chiropractors’ assumption of an obligatory birth trauma that causes subluxation and requires spinal adjustments is nothing more than a ploy by charlatans for filling their pockets with the cash of gullible parents.

The DAILY MAIL is by no means my favourite paper (see, for instance, here, here and here). This week, the Mail published another article which, I thought, is worth mentioning. The Mail apparently asked several UK doctors which dietary supplements they use for their own health (no mention of the number they had to approach to find any fitting into this category). The results remind me of a statement by the Permanent Secretary, Sir Humphrey Appleby in the famous TV series YES MINISTER: “if nobody knows anything then nobody can accuse anybody else of knowing nothing, and so the one thing we do know is that nobody knows anything, and that’s better than us knowing nothing”.

Below, I present the relevant quotes by the doctors who volunteered to be interviewed and add the most up-to date evidence on each subject.

Professor Christopher Eden, 57, is a consultant urological surgeon at the Royal Surrey County Hospital in Guildford.

“I take a 1g supplement of vitamin C daily. (The recommended daily amount, or RDA, is 40mg, which is equivalent to a large orange.) This amount of vitamin C makes the urine mildly acidic and increases the levels of an antimicrobial protein called siderocalin, found naturally in urine, which makes the environment less favourable to bad bacteria and reduces the risk of infection.”

Ascorbic acid (vitamin C) cannot be recommended for the prevention of urinary tract infections.

Louise Newson, 48, is a GP and menopause specialist based in Stratford-upon-Avon.

“Women going through the menopause or perimenopause may get bowel symptoms such as bloating which are due to hormone imbalances affecting the balance of gut bacteria. Probiotic (good bacteria) supplements correct this imbalance and are also linked to levels of the brain chemical serotonin, which can improve mood. This is important during the menopause. I make sure I take a probiotic daily, specifically one with a high bacteria count including Lactobacillus acidophilus. I look for one that has to be kept in the fridge, as this is a sign of a quality product.”

For … probiotics, prebiotics, acupuncture, homeopathy and DHEA-S, randomized, placebo-controlled trials are scarce and the evidence is unconvincing.

Professor Tony Kochhar, 45, is a consultant orthopaedic surgeon at London Bridge Hospital.

“Having taken statins for a couple of years, I developed tendonitis, inflammation in the foot, which caused pain around the outside of it. My GP told me to stop taking the statins, which helped, and I now control my condition with diet. I also take a supplement of collagen (a natural protein found in the tendons) to build up tendon structure and reduce pain. I take two 1,200mg collagen supplements daily and it has really helped. Within two weeks of starting them, my pain had gone.”

it is not possible to draw any definitive raccomendations on the use of nutraceutical supplementation in tendinopathies.

Dr Anne Rigg, 51, is a consultant oncologist at London Bridge Hospital.

“One theory is that vitamin D may help control normal breast cell growth and may even stop breast cancer cells from growing. The body creates vitamin D from sunlight on the skin when we are outdoors, but because of the British weather and the rightful use of sunscreen, it’s easy to become deficient. I take the recommended daily dose of 10mcg. [Fatty fish such as salmon and mackerel are good sources, too, but you’d have to eat them in large amounts to get the recommended daily dosage.] It’s vital not to overdose, as it can increase the risk of kidney stones: the vitamin helps absorb calcium from the diet, which can build up into stones.”

Supplementation with vitamin D did not result in a lower incidence of invasive cancer…

Dr Rob Hogan, 62, is an optometrist at iCare Consulting.

“I’m aware, too, of the increased risk of age-related macular degeneration (AMD), a leading cause of sight loss in people over 60. This is where the small central portion of the retina (the macula) at the back of the eye deteriorates. So I take MacuShield, a supplement which, studies have found, can help improve vision and keep the back of the eye healthy. It contains a mixture of natural compounds — lutein, zeaxanthin and meso-zeaxanthin — which are antioxidants that have been found in studies to improve vision and eye health. I take one a day, usually with a meal.”

In early AMD, macular pigment can be augmented with a variety of supplements, although the inclusion of MZ may confer benefits in terms of panprofile augmentation and in terms of contrast sensitivity enhancement.

Dr Milad Shadrooh, 37, is a dentist in Basingstoke, Hampshire.

“I take a varied supplement daily to maintain good health and, specifically, healthy teeth. It contains calcium (an adult’s RDA is 700mg, which is equivalent to three 200ml cups of milk) as most people, including me, don’t get enough in their diet.”

calciumsupplements that are used to prevent or treat osteoporosis appear to have beneficial effects on tooth retention as well.

Dr Joanna Gach, 49, is a consultant dermatologist at University Hospitals Coventry and Warwickshire NHS Trust.

“Every so often, I take a multivitamin capsule containing zinc, selenium and biotin. These are all helpful for sorting out my brittle nails and maintaining healthy hair.”

 no evidence supports the use of vitamin supplementation with vitamin E, vitamin C (ascorbic acid), vitamin A, retinoids, retinol, retinal, silicon, zinc, iron, copper, selenium, or vitamin B12 (Cyanocobalamin) for improving the nail health of well-nourished patients or improving the appearance of nails affected by pathologic disease.

Luke Cascarini, 47, is a consultant maxillofacial surgeon at Guy’s and St Thomas’ Hospital in London.

“I take a daily vitamin drink containing a high-dose vitamin B complex, which is necessary for good oral health.”

The published research reveals only a possible relationship between vitamins and minerals and periodontal disease. Vitamin E, zinc, lycopene and vitamin B complex may have useful adjunct benefits. However, there is inadequate evidence to link the nutritional status of the host to periodontal inflammation. More randomized controlled trials are needed to explore this association.

Dr Jenni Byrom, 44, is a consultant gynaecologist at Birmingham’s Women’s and Children’s Hospital.

“I take evening primrose oil for premenstrual symptoms such as breast pain. I take 1g of evening primrose oil daily and have found it really makes a difference.”

Evening primrose oil has not been shown to improve breast pain, and has had its licence withdrawn for this indication in the UK owing to lack of efficacy (it is still available to purchase without prescription).

Dr Sarah Myhill, 60, is a GP based in Wales.

“I take 10g of vitamin C dissolved in a glass of water every day before I start my shift — and I never get colds. I believe that high doses of vitamin C can kill bad microbes on contact — or, at least, help reduce the severity of infections such as colds and sore throats.”

 vitamin C has minimal or no impact on the duration of common cold or in the number of days at home or out of work.

Jonathan Dearing, 49, is a consultant orthopaedic surgeon specialising in sports injuries at BMI Carrick Glen Hospital in Ayrshire.

“I carry a vitamin D oral spray and use it after exercise, as it helps improve muscle recovery by regulating various processes that help them repair and grow.”

… supraphysiological dosages of vitamin D3 have potential ergogenic effects on the human metabolic system and lead to multiple physiological enhancements. These dosages could increase aerobic capacity, muscle growth, force and power production, and a decreased recovery time from exercise. These dosages could also improve bone density. However, both deficiency (12.5 to 50 nmol/L) and high levels of vitamin D (>125 nmol/L) can have negative side effects, with the potential for an increased mortality. Thus, maintenance of optimal serum levels between 75 to 100 nmol/L and ensuring adequate amounts of other essential nutrients including vitamin K are consumed, is key to health and performance. Coaches, medical practitioners, and athletic personnel should recommend their patients and athletes to have their plasma 25(OH)D measured, in order to determine if supplementation is needed. Based on the research presented on recovery, force and power production, 4000-5000 IU/day of vitamin D3 in conjunction with a mixture of 50 mcg/day to 1000 mcg/day of vitamin K1 and K2 seems to be a safe dose and has the potential to aid athletic performance. Lastly, no study in the athletic population has increased serum 25(OH)D levels past 100 nmol/L, (the optimal range for skeletal muscle function) using doses of 1000 to 5000 IU/day. Thus, future studies should test the physiological effects of higher dosages (5000 IU to 10,000 IU/day or more) of vitamin D3 in combination with varying dosages of vitamin K1 and vitamin K2 in the athletic population to determine optimal dosages needed to maximize performance.

Firstly, let me congratulate those colleagues who actually might have got it right:

  1. Dr Hogan
  2. Dr Shadrooh
  3. Mr Cascarini
  4. Mr Dearing

I say ‘MIGHT HAVE GOT IT RIGHT’ because, even in their cases, the evidence is far from strong and certainly not convincing.

Secondly, let me commiserate those who spend their money on unproven supplements. I find it sad that this group amounts to two thirds of all the ‘experts’ asked.

Thirdly, let me remind THE DAILY MAIL of what I posted recently:  journalists to be conscious of their responsibility not to mislead the public and do more rigorous research before reporting on matters of health. Surely, the Mail did us no favour in publishing this article. It will undoubtedly motivate lots of gullible consumers to buy useless or even harmful supplements.

And lastly, let me remind all healthcare professionals that promoting unproven treatments to the unsuspecting public is not ethical.

 

According to the 2014 European Social Survey, Spain is relatively modest when it comes to using alternative therapies. While countries such as Austria, Denmark, Estonia, Finland, France, Germany, Lithuania, Sweden and Switzerland all have 1-year prevalence figures of over 30%, Spain only boasts a meagre 17%. Yet, its opposition to bogus treatments has recently become acute.

In 2016, it was reported that a master’s degree in homeopathic medicine at one of Spain’s top universities has been scrapped. Remarkably, the reason was “lack of scientific basis”. A university spokesman confirmed the course was being discontinued and gave three main reasons: “Firstly, the university’s Faculty of Medicine recommended scrapping the master’s because of the doubt that exists in the scientific community. Secondly, a lot of people within the university – professors and students across different faculties – had shown their opposition to the course. Thirdly, the postgraduate degree in homeopathic medicine is no longer approved by Spain’s Health Ministry.”

A few weeks ago, I had the great pleasure of being invited to a science festival in Bilbao and was impressed by the buoyant sceptic movement in Spain. At the time, two of my books were published in Spanish and received keen interest by the Spanish press.

 

And now, it has been reported that Spain’s Ministry of Health has released a list of only 2,008 homeopathic products whose manufacturers will have to apply for an official government license for if they wish to continue selling them. The homeopathic producers have until April 2019 to prove that their remedies actually work, which may very well completely slash homeopathic products in Spain.

It’s the latest blow for Spain’s homeopathy industry, once worth an estimated €100 million but which has seen a drop in public trust and therefore sales of around 30 percent in the last five years. Spain’s Health Ministry stopped allowing homeopathy treatments from being prescribed as part of people’s social security benefits, along with acupuncture, herbal medicine and body-based practices such as osteopathy, shiatsu or aromatherapy.

“Homeopathy is an alternative therapy that has not shown any scientific evidence that it works” Spanish Minister of Health Maria Luisa Carcedo is quoted as saying in La Vanguardia in response to the homeopathic blacklist. “I’m committed to combatting all forms of pseudoscience.”

Even though illegal and unethical, many remedies used in Traditional Chinese Medicine (TCM) still contain animal parts. This fact has long concerned critics. Not only is there no evidence that these ingredients have any positive health effects, they also endanger the survival of endangered species. In the past, China has paid lip service to conservation and evidence. However, even these half-hearted pronouncements seem to be a thing of the past.

China’s State Council is now replacing its 1993 ban on the trade of tiger bones and rhino horn. Horns of rhinos or bones of tigers that were bred in captivity can hence force be used “for medical research or clinical treatment of critical illnesses” under the new rules. The fact that no critical illness responds to either of these remedies seems to matter little.  Grave concern has therefore been voiced by the World Wildlife Fund (WWF) over China’s announcement.

“It is deeply concerning that China has reversed its 25 year old tiger bone and rhino horn ban, allowing a trade that will have devastating consequences globally”, said Margaret Kinnaird, WWF Wildlife Practice Leader. “Trade in tiger bone and rhino horn was banned in 1993. The resumption of a legal market for these products is an enormous setback to efforts to protect tigers and rhinos in the wild. China’s experience with the domestic ivory trade has clearly shown the difficulties of trying to control parallel legal and illegal markets for ivory. Not only could this lead to the risk of legal trade providing cover to illegal trade, this policy will also stimulate demand that had otherwise declined since the ban was put in place.”

Both tiger bone and rhino horn were removed from the TCM pharmacopeia in 1993, and the World Federation of Chinese Medicine Societies released a statement in 2010 urging members not to use tiger bone or any other parts from endangered species. Even if restricted to antiques and use in hospitals, the WWF argue, this trade would increase confusion by consumers and law enforcers as to which products are and are not legal, and would likely expand the markets for other tiger and rhino products. “With wild tiger and rhino populations at such low levels and facing numerous threats, legalized trade in their parts is simply too great a gamble for China to take. This decision seems to contradict the leadership China has shown recently in tackling the illegal wildlife trade, including the closure of their domestic ivory market, a game changer for elephants warmly welcomed by the global community,” Kinnaird added.

WWF calls on China to set a clear plan and timeline to close existing captive tiger breeding facilities used for commercial purposes. Such tiger farms pose a high risk to wild tiger conservation by complicating enforcement and increasing demand in tiger products.

China’s announcement comes at the precise moment when we learnt from the 2018 edition of the Living Planet Report that, between 1970 and 2014, there was 60% decline, on average, among 16,700 wildlife populations around the world. The Living Planet report, issued every two years to track global biodiversity, is based on the Living Planet Index, put out every two years since 1998 in collaboration with the Zoological Society of London and based on international databases of wildlife populations. The two previous reports, in 2014 and 2016, found wildlife population declines of 50% and 58%, respectively, since 1970.

Really?

For dogs?

Yes, one (of many) website explains that dogs benefit from acupuncture in 5 different ways:

1. Pain management is one of the most common uses for acupuncture, often in conjunction with a more traditional treatment plan. Strong medical treatments like chemo, which can cause discomfort, are often paired with acupuncture to help make a pet more comfortable and able to fight the illness.

2. Musculoskeletal problems such as arthritis, hip dysplasia, or nerve injuries can respond to acupuncture. It is often employed during rehabilitation after an injury. Carefully monitoring a healing pet is important; without the feeling of pain, a dog can re-injure him or herself with over-activity.

3. Skin problems like allergic dermatitis, granulomas, or hot spots may respond well to acupuncture treatment because increased circulation can improve healing, while pain reduction will reduce a dog’s overgrooming or itching responses.

4. Gastrointestinal problems like nausea and diarrhea can be aided by the increased blood flow from acupuncture. It may also help normalize digestive activity by stimulating digestive secretions.

5. Respiratory problems like asthma and allergies can benefit from the immune-calming, anti-inflammatory capabilities of acupuncture.

But all of this is based on ‘experience’ (or probably more accurately, the wishful thinking of those who earn money by sticking needles into animals), not evidence!

So, what does the evidence tell us about acupuncture for dogs?

The answer is: next to nothing; there are almost no studies. And this is why this recent paper could be important.

This new study was aimed at quantifying changes in gastric and intestinal emptying times in the conscious dog following gastrointestinal acupoint stimulation.

In a randomised, blinded crossover study, six dogs were fed 30×1.5 mm barium-impregnated polyethylene spheres and underwent: (1) no acupuncture (Control); (2) stimulation of target points PC6 and ST36 (Target) and (3) stimulation of non-target points LU7 and BL55 (Sham). Abdominal radiographs were assessed immediately after feeding the spheres and every hour for 12 hours and their number in the stomach and large intestines was counted.

The number of barium-impregnated polyethylene spheres found distal to the stomach was less in the Target group compared to the Control and Sham groups between hours 2 and 4, but no differences between groups were seen for the remainder of the treatment period. The number of spheres found within the colon/rectum was less in the Target group compared to the Control and Sham groups between hours 4 and 6, and compared to the Sham group only at hour 7 but no differences between groups were seen after hour 8.

The authors concluded that acupuncture targeted at the gastrointestinal tract of dogs was associated briefly with slowed gastric emptying and gastrointestinal transit time. This foundational study lays the groundwork for additional studies of acupuncture effects associated with altered physiologic states.

There you have it: the proof has been presented that acupuncture works in dogs; and if it works in animals, it cannot be a placebo!

Hold on, not so quick!

This was a tiny study, and the effects are small, only temporary and of questionable relevance. It is possible (I’d say even likely) that the finding was entirely coincidental.

I think, I wait until we have more and better data.
