The ‘International Federation of Anthroposophic Medical Associations’ have just published a ‘Statement on Vaccination‘. Here it is in its full beauty:

Vaccines, together with health education, hygiene and adequate nutrition, are essential tools for preventing infectious diseases. Vaccines have saved countless lives over the last century; for example, they allowed the eradication of small pox and are currently allowing the world to approach the elimination of polio.

Anthroposophic Medicine fully appreciates the contribution of vaccines to global health and firmly supports vaccination as an important measure to prevent life threatening diseases. Anthroposophic Medicine is not anti-vaccine and does not support anti-vaccine movements.

Physicians with training in Anthroposophic Medicine are expected to act in accordance with national legislation and to carefully advise patients (or their caregivers) to help them understand the relevant scientific information and national vaccination recommendations. In countries where vaccination is not mandatory and informed consent is needed, this may include coming to agreement with the patient (or the caregivers) about an individualized vaccination schedule, for example by adapting the timing of vaccination during infancy.

Taking into account ongoing research, local infectious disease patterns and socioeconomic risk factors, individual anthroposophic physicians are at times involved in the scientific discussion about specific vaccines and appropriate vaccine schedules. Anthroposophic Medicine is pro-science and continued scientific debate is more important than ever in today’s polarized vaccine environment.

Already in 2010, The European Council for Steiner Waldorf Education published a press release, implying a similar stance:

We wish to state unequivocally that opposition to immunization per se, or resistance to national strategies for childhood immunization in general, forms no part of our specific educational objectives. We believe that a matter such as whether or not to innoculate a child against communicable disease should be a matter of parental choice. Consequently, we believe that families provide the proper context for such decisions to be made on the basis of medical, social and ethical considerations, and upon the perceived balance of risks. Insofar as schools have any role to play in these matters, we believe it is in making available a range of balanced information both from the appropriate national agencies and qualified health professionals with expertise in the filed. Schools themselves are not, nor should they attempt to become, determiners of decisions regarding these matters.

Such statements sound about right. Why then am I not convinced?

Perhaps because there are hundreds of anthroposophic texts that seem to contradict this pro-vaccination stance (not least those from Rudolf Steiner himself). Today, anthroposophy enthusiasts are frequently rampant anti-vax; look at this quote, for instance:

… anthroposophic and con­ventional medicine have dramati­cally different viewpoints as to what causes common childhood illnesses. Conventional medicine views child­hood illnesses for which vaccines have been developed as a physical disease, inherently bad, to be pre­vented. Their main goal, therefore, is protection against contracting the disease making one free of illness. In contrast, these childhood illnesses are viewed by anthroposophic medi­cine as a necessary instrument in dealing with karma and, as discussed by Husemann, and Wolff, 6 the incar­nation of the child. During childhood illnesses, anthroposophic medical practitioners administer medical remedies to assist the child in deal­ing with the illness not only as a dis­ease affecting their physical body in the physical plane, but also for soul ­spiritual development, thereby pro­moting healing. In contrast, allopathic medicaments are aimed at suppression of symptoms and not necessarily the promotion of healing.

In Manifestations of Karma, Rudolf Steiner states that humans may be able to influence their karma and remove the manifestation of cer­tain conditions, i.e., disease, but they may not be liberated from the karmic effect which attempted to produce them. Says Steiner, “…if the karmic reparation is escaped in one direc­tion, it will have to be sought in another … the souls in question would then be forced to seek another way for karmic compensation either in this or in another incarnation.” 7

In his lecture, Karma of Higher Beings 8, Steiner poses the question, “If someone seeks an opportunity of being infected in an epidemic, this is the result of the necessary reaction against an earlier karmic cause. Have we the right now to take hy­gienic or other measures?” The an­swer to this question must be decided by each person and may vary. For example, some may accept the risk of disease but not of vaccine side effects, while others may accept the risk associated with vaccination but not with the disease.

Anthroposophic medicine teaches that to prevent a disease in the physical body only postpones what will then be produced in an­other incarnation. Thus, when health measures are undertaken to eliminate the susceptibility to a disease, only the external nature of the illness is eliminated. To deal with the karmic activity from within, Anthroposphy states that spiritual education is re­quired. This does not mean that one should automatically be opposed to vaccination. Steiner indicates that “Vaccination will not be harmful if, subsequent to vaccination, a person receives a spiritual education.”

Or consider this little statistic from the US:

Waldorf schools are the leading Nonmedical Exemption [of vaccinations] schools in various states, such as:

  • Waldorf School of Mendocino County (California) – 79.1%
  • Tucson Waldorf Schools (Arizona) – 69.6%
  • Cedar Springs Waldorf School (California) – 64.7%
  • Waldorf School of San Diego (California) – 63.6%
  • Orchard Valley Waldorf School (Vermont) – 59.4%
  • Whidbey Island Waldorf School (Washington) – 54.9%
  • Lake Champlain Waldorf School (Vermont) – 49.6%
  • Austin Waldorf School (Texas) – 48%

Or what about this quote?

Q: I am a mother who does not immunize my children.  I feel as though I have to keep this a secret.  I recently had to take my son to the ER for a tetanus shot when he got a fish hook in his foot, and I was so worried about the doctor asking if his shots were current.  His grandmother also does not understand.  What do you suggest?

A: You didn’t give your reasons for not vaccinating your children.  Perhaps you feel intuitively that vaccinations just aren’t good for children in the long run, but you can’t explain why.  If that’s the case, I think your intuition is correct, but in today’s contentious world it is best to understand the reasons for our decisions and actions.

There are many good reasons today for not vaccinating children in the United States  I recommend you consult the book, The Vaccination Dilemma edited by Christine Murphy, published by SteinerBooks.

So, where is the evidence that anthroposophy-enthusiasts discourage vaccinations?

It turns out, there is plenty of it! In 2011, I summarised some of it in a review concluding that numerous reports from different countries about measles outbreaks centered around Steiner schools seem nevertheless to imply that a problem does exist. In the interest of public health, we should address it.

All this begs a few questions:

  • Are anthroposophy-enthusiasts and their professional organisations generally for or against vaccinations?
  • Are the statements above honest or mere distractions from the truth?
  • Why are these professional organisations not going after their members who fail to conform with their published stance on vaccination?

I suspect I know the answers.

What do you think?

Collagen is a fibrillar protein of the conjunctive and connective tissues in the human body, essentially skin, joints, and bones. Due to its abundance in our bodies, its strength and its relation with skin aging, collagen has gained great interest as an oral dietary supplement as well as an ingredient in cosmetics. Collagen fibres get damaged with the pass of time, losing thickness and strength which has been linked to skin aging phenomena. Collagen can be obtained from natural sources such as plants and animals or by recombinant protein production systems. Because of its increased use, the collagen market is worth billions. The question therefore arises: is it worth it?

This 2019 systematic review assessed all available randomized-controlled trials using collagen supplementation for treatment efficacy regarding skin quality, anti-aging benefits, and potential application in medical dermatology. Eleven studies with a total of 805 patients were included. Eight studies used collagen hydrolysate, 2.5g/d to 10g/d, for 8 to 24 weeks, for the treatment of pressure ulcers, xerosis, skin aging, and cellulite. Two studies used collagen tripeptide, 3g/d for 4 to 12 weeks, with notable improvement in skin elasticity and hydration. Lastly, one study using collagen dipeptide suggested anti-aging efficacy is proportionate to collagen dipeptide content.

The authors concluded that preliminary results are promising for the short and long-term use of oral collagen supplements for wound healing and skin aging. Oral collagen supplements also increase skin elasticity, hydration, and dermal collagen density. Collagen supplementation is generally safe with no reported adverse events. Further studies are needed to elucidate medical use in skin barrier diseases such as atopic dermatitis and to determine optimal dosing regimens.

These conclusions are similar to those of a similar but smaller review of 2015 which concluded that the oral supplementation with collagen peptides is efficacious to improve hallmarks of skin aging.

And what about the many other claims that are currently being made for oral collagen?

A 2006 review of collagen for osteoarthritis concluded that a growing body of evidence provides a rationale for the use of collagen hydrolysate for patients with OA. It is hoped that ongoing and future research will clarify how collagen hydrolysate provides its clinical effects and determine which populations are most appropriate for treatment with this supplement. For other indication, the evidence seems less conclusive.

So, what should we make of this collective evidence. My interpretation is that, of course, there are caveats. For instance, most studies are small and not as rigorous as one would hope. But the existing evidence is nevertheless intriguing (and much more compelling than that for most other supplements). Moreover, there seem to be very few adverse effects with oral usage (don’t inject the stuff for cosmetic purposes, as often recommended!). Therefore, I feel that collagen might be one of the few dietary supplements worth keeping an eye on.

The notion that ‘chiropractic adds years to your life’ is often touted, particularly of course by chiropractors (in case you doubt it, please do a quick google search). It is logical to assume that chiropractors themselves are the best informed about what they perceive as the health benefits of chiropractic care. Chiropractors would therefore be most likely to receive some level of this ‘life-prolonging’ chiropractic care on a long-term basis. If that is so, then chiropractors themselves should demonstrate longer life spans than the general population.

Sounds logical?

Perhaps, but is the theory supported by evidence?

Back in 2004, a chiropractor, Lon Morgan,  courageously tried to test the theory and published an interesting paper about it.

He used two separate data sources to examine the mortality rates of chiropractors. One source used obituary notices from past issues of Dynamic Chiropractic from 1990 to mid-2003. The second source used biographies from Who Was Who in Chiropractic – A Necrology covering a ten year period from 1969-1979. The two sources yielded a mean age at death for chiropractors of 73.4 and 74.2 years respectively. The mean ages at death of chiropractors is below the national average of 76.9 years; it also is below the average age at death of their medical doctor counterparts which, at the time, was 81.5.

So, one might be tempted to conclude that ‘chiropractic substracts years from your life’. I know, this would be not very scientific – but it would probably be more evidence-based than the marketing gimmick of so many chiropractors trying to promote their trade by saying: ‘chiropractic adds years to your life’!

In any case, Morgan, the author of the paper, concluded that this paper assumes chiropractors should, more than any other group, be able to demonstrate the health and longevity benefits of chiropractic care. The chiropractic mortality data presented in this study, while limited, do not support the notion that chiropractic care “Adds Years to Life …”, and it fact shows male chiropractors have shorter life spans than their medical doctor counterparts and even the general male population. Further study is recommended to discover what factors might contribute to lowered chiropractic longevity.

Another beautiful theory killed by an ugly fact!

Most chiropractors claim that their manipulations prevent illness, not just spinal but also non-spinal conditions. But is there any sound evidence for that assumption? A team of chiropractic researchers wanted to find out. Specifically, the objective of their systematic review was to investigate if there is any evidence that spinal manipulations/chiropractic care can be used in primary prevention (PP) and/or early secondary prevention in diseases other than musculoskeletal conditions.

Of the 13.099 titles scrutinized by the authors, 13 articles were included. These were

  • 8 clinical studies,
  • 5 population studies.

These studies dealt with various issues such as

  • diastolic blood pressure,
  • blood test immunological markers,
  • and mortality.

Only two clinical studies could be used for data synthesis. None showed any effect of spinal manipulation/chiropractic treatment.

The authors’ conclusions were straight forward: we found no evidence in the literature of an effect of chiropractic treatment in the scope of PP or early secondary prevention for disease in general. Chiropractors have to assume their role as evidence-based clinicians and the leaders of the profession must accept that it is harmful to the profession to imply a public health importance in relation to the prevention of such diseases through manipulative therapy/chiropractic treatment.

Many chiropractors have adopted the ‘dental model’ in their practice, proposing to prevent all sorts of conditions through treatment of spinal subluxations before symptoms arise. Some call this approach ‘maintenance care’ and liken it to the need for servicing a car. They tell their patients that regular consultations will prevent problems in the future. It seems obvious that this can be a nice little earner. In 2009, I reviewed the evidence on chiropractic maintenance treatment. Here is the abstract:

Most chiropractors advise patients to have regular maintenance treatments with spinal manipulation, even in the absence of any symptoms or diseases. This article evaluates the evidence for or against this approach. No compelling evidence was found to indicate that chiropractic maintenance therapy effectively prevents symptoms or diseases. As spinal manipulation has repeatedly been associated with considerable harm, the risk benefit balance of chiropractic maintenance care is not demonstrably positive. Therefore there are no good reasons to recommend it.

The new review confirms that this approach is useful only for filling the pockets of chiropractors.


On their website, the UK ‘ROYAL COLLEGE OF CHIROPRACTORS (RCC) published a short statement regarding the safety of chiropractic. Here it is in full:

Experiencing mild or moderate adverse effects after manual therapy, such as soreness or stiffness, is relatively common, affecting up to 50% of patients. However, such ‘benign effects’ are a normal outcome and are not unique to chiropractic care.

Cases of serious adverse events, including spinal or neurological problems and strokes caused by damage to arteries in the neck, have been associated with spinal manipulation. Such events are rare with estimates ranging from 1 per 2 million manipulations to 13 per 10,000 patients; furthermore, due to the nature of the underlying evidence in relation to such events (case reports, retrospective surveys and case-control studies), it is very difficult to confirm causation (Swait and Finch, 2017).

For example, while an association between stroke caused by vertebral artery damage or ‘dissection’ (VAD) and chiropractor visits has been reported in a few case-control studies, the risk of stoke has been found to be similar after seeing a primary care physician (medical doctor). Because patients with VAD commonly present with neck pain, it is possible they seek therapy for this symptom from a range of practitioners, including chiropractors, and that the VAD has occurred spontaneously, or from some other cause, beforehand (Biller et al, 2014). This highlights the importance of ensuring careful screening for known neck artery stroke risk factors, or signs or symptoms that there is an ongoing problem, is performed prior to manual treatment of patients (Swait and Finch, 2017). Chiropractors are well trained to do this on a routine basis, and to urgently refer patients if necessary.


The statement reads well but it might not be entirely free from conflicts of interest. Yet, in the name of accuracy, completeness and truthfulness, I take the liberty of making a few slight alterations. Here is my revised version:

Experiencing mild or moderate adverse effects after chiropractic spinal manipulations, such as pain or stiffness (usually lasting 1-3 days and strong enough to impair patients’ quality of life), is very common. In fact, it affects around 50% of all patients. 

Cases of serious adverse events, including spinal or neurological problems and strokes often caused by damage to arteries in the neck, have been reported after spinal manipulation. Such events are probably not frequent (several hundred are on record including about 100 fatalities).  But, as we have never established proper surveillance systems, nobody can tell how often they occur. Furthermore, due to our reluctance of introducing such surveillance, some of us are able to question causality.

An association between stroke caused by vertebral artery damage or ‘dissection’ (VAD) and chiropractic spinal manipulation has been reported in about 20 independent investigations. Yet one much-criticised case-control study found the risk of stoke to be similar after seeing a primary care physician (medical doctor). Because patients with VAD commonly have neck pain, it is possible they seek therapy for this symptom from chiropractors, and that the VAD has occurred spontaneously, or from some other cause, beforehand (Biller et al, 2014). Ensuring careful screening for known neck artery stroke risk factors, or signs that there is an ongoing problem would therefore be important (Swait and Finch, 2017). Sadly, no reliable screening tests exist, and neck pain (the symptom that might be indicative of VAD) continues to be one of the conditions most frequently treated by chiropractors.

I do not expect the RCC to adopt my improved version. In case I am wrong, let me state this: I am entirely free of conflicts of interest and will not charge a fee for my revision. In the interest of advancing public health, I herewith offer it for free.

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.

Personally, I like sauna bathing. It makes me feel fine. But is it healthy? More specifically, is it good for the cardiovascular system?

Finnish researchers had already shown in a large cohort study with 20 years of follow-up that increased frequency of sauna bathing is associated with a reduced risk of sudden cardiac death (SCD), fatal coronary heart disease (CHD), fatal cardiovascular disease (CVD), and all-cause mortality. Now the same group of researchers report more encouraging news for sauna-fans.

The aim of their new study was to investigate the relationship between sauna habits and CVD mortality in men and women, and whether adding information on sauna habits to conventional cardiovascular risk factors is associated with improvement in prediction of CVD mortality risk.

Sauna bathing habits were assessed at baseline in a sample of 1688 participants (mean age 63; range 53-74 years), of whom 51.4% were women. Multivariable-adjusted hazard ratios (HRs) were calculated to investigate the relationships of frequency and duration of sauna use with CVD mortality.

A total of 181 fatal CVD events occurred during a median follow-up of 15.0 years (interquartile range, 14.1-15.9). The risk of CVD mortality decreased linearly with increasing sauna sessions per week with no threshold effect. In age- and sex-adjusted analysis, compared with participants who had one sauna bathing session per week, HRs (95% CIs) for CVD mortality were 0.71 (0.52 to 0.98) and 0.30 (0.14 to 0.64) for participants with two to three and four to seven sauna sessions per week, respectively. After adjustment for established CVD risk factors, potential confounders including physical activity, socioeconomic status, and incident coronary heart disease, the corresponding HRs (95% CIs) were 0.75 (0.52 to 1.08) and 0.23 (0.08 to 0.65), respectively. The duration of sauna use (minutes per week) was inversely associated with CVD mortality in a continuous manner. Addition of information on sauna bathing frequency to a CVD mortality risk prediction model containing established risk factors was associated with a C-index change (0.0091; P = 0.010), difference in - 2 log likelihood (P = 0.019), and categorical net reclassification improvement (4.14%; P = 0.004).

(Hazard ratios for cardiovascular mortality by quartiles of the duration of sauna bathing. a Adjusted for age and gender. b Adjusted for age, gender, body mass index, smoking, systolic blood pressure, serum low-density lipoprotein cholesterol, alcohol consumption, previous myocardial infarction, and type 2 diabetes. CI, confidence interval.)

The authors concluded that higher frequency and duration of sauna bathing are each strongly, inversely, and independently associated with fatal CVD events in middle-aged to elderly males and females. The frequency of sauna bathing improves the prediction of the long-term risk for CVD mortality.

These results are impressive. What could be the underlying mechanisms? The authors offer plenty of explanations: Dry and hot sauna baths have been shown to increase the demands of cardiovascular function. Sauna bathing causes an increase in heart rate which is a reaction to the body heat load. Heart rate may be elevated up to 120–150 beats per minute during sauna bathing, corresponding to low- to moderate-intensity physical exercise training for the circulatory system without active muscle work. Acute sauna exposure has been shown to produce blood pressure lowering effects, decrease peripheral vascular resistance and arterial stiffness, and improve arterial compliance. Short-term sauna exposure also activates the sympathetic nervous and the renin-angiotensin-aldosterone systems and the hypothalamus-pituitary-adrenal hormonal axis, and short-term increases in levels of their associated hormones have been reported. Repeated sauna exposure improves endothelial function, suggesting a beneficial role of thermal therapy on vascular function. Long-term sauna bathing habit may be beneficial in the reduction of high systemic blood pressure, which is in line with previous evidence showing that blood pressure may be lower among those who are living in warm conditions with higher ambient temperature. Regular sauna bathing is associated with a lowered risk of future hypertension. Typical hot and dry Finnish sauna increases body temperature which causes more efficient skin blood flow, leading to a higher cardiac output, whereas blood flow to internal organs decreases. Sweat is typically secreted at a rate which corresponds to an average total secretion of 0.5 kg during a sauna bathing session. Increased sweating is accompanied by a reduction in blood pressure and higher heart rate, while cardiac stroke volume is largely maintained, although a part of blood volume is diverted from the internal organs to body peripheral parts with decreasing venous return which is not facilitated by active skeletal muscle work. However, it has been proposed that muscle blood flow may increase to at least some extent in response to heat stress, although sauna therapy-induced myocardial metabolic adaptations are largely unexplored. There is also evidence that regular long-term sauna bathing (average of two sessions per week) increases left ventricular ejection fraction. Heat therapy may improve left ventricular function with decreased cardiac pre- and afterload, thereby maintaining appropriate stroke volume despite large reductions in ventricular filling pressures. Additionally, previous studies have demonstrated a positive alteration of the autonomic nervous system and reduced levels of natriuretic peptides, oxidative stress, inflammation, and norepinephrine due to regular sauna therapy.

It is possible that the results are influenced by confounding factors that the researchers were unable to account for. It is also possible that people who are already ill avoid sauna bathing and that this contributed to the findings. However, the authors did their best to explore such phenomena in sub-group analysis and found that a causal relationship between sauna and CVD risk is still very likely. As a sauna-fan, I am inclined to believe them and the sceptic in me tends to agree.

Many people seem to be amazed at my continued activities (e. g. blog, books, lectures, interviews) aimed at telling the truth about homeopathy and other alternative modalities. They ask themselves: why does he do it? And sometimes I ask myself the same question. I certainly don’t do it because I receive any money for my work (as many of my critics have assumed in the past).

So, why?

Let me briefly offer just 7 of the most obvious reasons why I feel it is important to tell the truth about homeopathy and similar treatments:

1. The truth is invaluable

I probably do not need to explain this at all. For any responsible person the truth has an intrinsic value that cannot be doubted. In our book, we conclude that “the truth-violating nature of CAM renders it immoral in both theory and practice.”

2. Untruths make a mockery of EBM

If we accept that, in the realm of alternative medicine, it is permissible to apply a different standard than in evidence-based medicine (EBM), we make a mockery of EBM. Double standards are hugely counter-productive and not in the interest of patients.

3. The truth promotes rationality

If the proponents of a modality such as homeopathy promote concepts that fly in the face of science, they undermine rational thinking. Believing in a vital force or energy is just one of many examples for this phenomenon. Undermining rationality can have negative effects far beyond healthcare and reminds me of Voltaire’s bon mot: “Those who make you believe in absurdities can make you commit atrocities.”

4. It is ethical

Healthcare have the ethical duty to work towards patients receiving the best treatments available. If a therapy like homeopathy fails to be demonstrably effective, it cannot possibly fall into this category. Therefore, responsible healthcare professionals must help to improve healthcare by disclosing the evidence against homeopathy.

5. It might save money

The money spent on homeopathy and other ineffective alternative treatments is considerable. Disclosing the fact that they are not effective will help stopping people to waste their money on them. Telling the truth about homeopathy and similarly ineffective therapies would therefore save funds that can be used more efficiently elsewhere.

6. It might save lives

Because they usually are free of active molecules, homeopathic remedies are often seen as a safe treatments. However, homeopathy can nevertheless harm and even kill patients, if they use it as an alternative medicines in cases of severe illness. It follows that telling the truth about homeopathy’s ineffectiveness can save lives.

7. It could counter-balance the multiple lies that are being told.

We all have seen the multitude of untruths that are being told about the value of homeopathy (if you haven’t, you ought to read SCAM). The multitude of falsehoods seriously misleads many consumers into believing that homeopathy is a valuable therapeutic option for many conditions. I feel strongly that it is my moral duty as an independent expert to counter-balance this plethora of lies in order to minimise the harm it is doing.

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.

“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).

“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.

“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.

“I take a magnesium supplement as it can help address an extra heartbeat — something I suffered with for 20 years.”

Whether magnesium supplementation could have a role in the prevention of AF in the community has not been tested.


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.


Homotoxicology is sometimes praised as the ‘best kept detox secret‘, often equated with homeopathy, and even more often not understood at all.

But what is it really?

Homotoxicology is the science of toxins and their removal from the human body. It offers a theory of disease which describes the severity and duration of an illness or disorder based on toxin-loading relative to our body’s ability to detoxify. In other words, it tells you how sick you’ll get when what stays inside progressively overwhelms our ability to get the garbage out. It explains what you can expect to see as you start removing toxins.

And yes, there is a hierarchy of toxic substances. Homotoxicology says you should remove the gentler ones first. As the body strengthens, it will be able to handle the really bad stuff (i.e., heavy metals). This explains why some people do really well on the same detox treatments that take others out at the knees.

Yes, I know!

This sounds very much like promotional BS!!!

So, what is it really, and what evidence is there to support it?

Homotoxicolgy is a therapy developed by the German physician and homeopath Hans Reckeweg. It is strongly influenced by (but not identical with) homoeopathy. Proponents of homotoxicology understand it as a modern extension of homoeopathy developed partly in response to the effects of the Industrial Revolution, which imposed chemical pollutants on the human body.

„Ich möchte einmal die Homöopathie mit der Schulmedizin verschmelzen H.-H. Reckeweg Küstermann/Auriculotherapie_2008.

According to the assumptions of homotoxicology, any human disease is the result of toxins, which originate either from within the body or from its environment. Allegedly, each disease process runs through six specific phases and is the expression of the body’s attempt to cope with these toxins. Diseases are thus viewed  as biologically useful defence mechanisms. Health, on the other hand, is the expression of the absence of toxins in our body. It seems obvious that these assumptions are not based on science and bear no relationship to accepted principles of toxicology or therapeutics. In other words, homotoxicology is not plausible.
The therapeutic strategies of homotoxicology are essentially threefold:

• prevention of further homotoxicological challenges,
• elimination of homotoxins,
• treatment of existing ‘homotoxicoses’.

Frequently used homotoxicological remedies are fixed combinations of homeopathically prepared remedies such as nosodes, suis-organ preparations and conventional drugs. All these remedies are diluted and potentised according to the rules of homoeopathy. Proponents of homotoxicology claim that they activate what Reckeweg called the ‘greater defence system’— a concerted neurological, endocrine, immunological, metabolic and connective tissue response that can give rise to symptoms and thus excretes homotoxins. Homotoxicological remedies are produced by Heel, Germany and are sold in over 60 countries. The crucial difference between homotoxicology and homoeopathy is that the latter follows the ‘like cures like’ principle, while the former does not. As this is the defining principle of homeopathy, it would be clearly wrong to assume that homotoxicology is a form of homeopathy.

Several clinical trials of homotoxicology are available. They are usually sponsored or conducted by the manufacturer. Independent research is very rare. In most major reviews, these studies are reviewed together with trials of homeopathic remedies which is obviously not correct. Our systematic review purely of studies of homotoxicology included 7 studies, all of which had major flaws. We concluded that the placebo-controlled, randomised clinical trials of homotoxicology fail to demonstrate the efficacy of this therapeutic approach.

So, I ask again: what is homotoxicology?

It is little more than homeopathic nonsense + detox nonsense + some more nonsense.

My advice is to say well clear of it.
