Structured Water – Hogwash?

Posted 08 August 2022

At Better Water SA, Marieke Bos claims “I am passionate about structured enhanced water and I would like to share. This great technology can benefit you and the whole of South Africa“.  Similarly at Designer Water the following is claimed: “Structured water does not have the same properties as bulk water” and “Structured water is not a myth, this useful phenomenon can improve health and rejuvenate the body, scientists say.‘ At Trivortex, similar claims are made: “For optimal cellular hydration, it is important to present cells with structured water” with the scam claim that “[T]he subtle energy fields of the Tri-Vortex treated Water Disc creates structure in any liquid within a few minutes”.

Why microbiome tests are currently of limited value for your clinical practice

Posted 29 July 2022

This article concludes:

Microbiome testing is still in its infancy. Here is a summary of some clinical takeaways that you can explain to your patients the next time they ask about the utility of microbiome tests:

  • Scientists have not yet defined a healthy or normal gut microbiome that can reliably predict whether a person will develop a particular disease.
  • Relying on stool samples for studying the gut microbiome is inaccurate as the microbiome in stool does not faithfully reflect the microbiome at the intestinal mucosa. The stool microbiome is stable over time and different from the luminal microbiome, which varies depending on each part of the gastrointestinal tract.
  • Some commercial microbiome test reports describe the patient’s gut microbiome profile in terms of “good” and “bad” bacteria. The behavior of a particular gut microbe depends on the environment in which it lives and interactions with other commensal

DNA Diet – Dnalysis still ‘duping’ clients?

Posted 19 July 2022

Dnanalysis continues to claim efficacy for the genetic testing and diet/weight-loss efficacy.

On the website, they claim “DNA Diet® is a genetic test designed to guide the personalisation of diet and lifestyle recommendations in order to manage weight. It provides insight into which diet type (low carbohydrate, low fat, or Mediterranean diet) would be most suitable for you according to your unique genetic makeup.”

Yet years after starting with these claims, the evidence to back up claims that a DNA test can assist with weight-loss or weigh management remains very thin.

Here is the most recent article rebutting these claims:

But, as people got older, we also noticed differences in their weight that couldn’t be explained by genetics or social background. This meant that neither of those factors is a good predictor of any particular person’s body weight.

Study looks at tainted dietary supplements

Posted 06 July 2022

The U.S. Food and Drug Administration’s Tainted Supplements Database, created in 2007, lists products adulterated with active pharmaceutical ingredients (APIs). Between 2007 and 2021, 1,068 unique dietary-supplement products were added to the database. A recent study has found that the products likely to include APIs were for sexual enhancement and weight loss.

The author noted:

  • Since 2016, the percentage of products containing more than one API has increased.
  • Since 2016, the percentage of adulterated products for sexual enhancement was higher, the percentage of weight-loss products was lower, and no muscle-building products were reported.
  • Some products with APIs were removed from the market by the FDA because the risks were too great, some were never reviewed by the FDA, and some combined multiple APIs in ways that make it impossible to determine how benefits compare to harms.

Immune Boosters – Scam?

Posted 05 July 2022

A number of products claim to be immune boosters.

These reputable articles argue that these claims are invalid and not physiologically possible – unless you are undernourished or malnourished.

BBC: Covid-19: Can ‘boosting’ your immune system protect you?

“Unfortunately, the idea that pills, trendy superfoods or wellness habits can provide a shortcut to a healthy immune system is a myth. In fact, the concept of “boosting” your immune system doesn’t hold any scientific meaning whatsoever.”


Cedars Sinai Hospital: Can You Really Boost Your Immune System?

“Dr. Cassel says most of the things people take to boost their immune system, such as vitamins or supplements, don’t have any effect on your immune response.”

Adaptogen hype scrutinised

Posted 28 June 2022

“They are claimed to cure everything, even long COVID. But the science on adaptogens is very disappointing.”

Adaptogens are said to be substances, often plants (such as ginseng and golden root), that help the body adapt to stress with no side effects. A recent article makes these points:

  • Their long-term safety has not been demonstrated.
  • Regulation of this market is poor.
  • Some adaptogenic herbs are known to have potentially serious side effects.
  • Evidence for effectiveness usually comes from animal studies and a few published studies in humans that tend to be small and lacking in rigor.

Why Too Many Vitamins Feels Just About Right

Posted 23 June 2022

This editorial published in JAMA (Journal of the American Medical Association) asks:

“Essential nutrients plus clever marketing: it is clear why vitamin and mineral supplements are so appealing. But that begs the question of why it is so easy to market the unproven benefits of these products while it is so difficult to convince people to receive lifesaving vaccines.”

Why Too Many Vitamins Feels Just About Right

JAMA Intern Med. Published online June 21, 2022. doi:10.1001/jamainternmed.2022.0119

Currently, US adults spend more than $10 billion per year on vitamins and dietary supplements,1 believing against most evidence that fortified gummy bears and water infused with vitamins will improve their health and well-being.

Can Supplements Really Help With Depression or Anxiety?

Posted 17 June 2022


Here’s what the evidence says about what works (and what doesn’t).

St. John’s wort “promotes a positive mood.” Valerian root reduces “levels of anxiety and stress.” Lavender oil is “calming for body and mind.”

If you are among the tens of millions of people in the United States who suffer from depression or anxiety, it is easy to be captivated by the promise of mood-boosting supplements. Take these pills daily, their marketing suggests, and soon you’ll be happily bouncing through verdant, sun-soaked fields, no prescription required.

But, while experts say that some mood-lifting supplements are better studied than others, the wider evidence on their effectiveness is shaky at best. “I’m not saying that there’s evidence that these things aren’t useful,” said Dr. Gerard Sanacora, a professor of psychiatry at the Yale School of Medicine

Paediatric melatonin poisonings increasing

Posted 12 June 2022

Melatonin, which is regulated by the U.S. Food and Drug Administration as a dietary supplement, is widely used as a sleep aid.

‘Designer Water’ and Alkaline water – pure scam

Posted 27 May 2022

Modern snake-oil sellers have a sciency-sounding shtick about them, but ‘alkaline’ or ‘ionised’ water is a swindle.

Adverts for a fancy water brand called Designer Water are all over Facebook. My local gym sells it. The ads circulate on WhatsApp groups. There is a multi-level marketing scheme for it, à la Herbalife, Avon, Amway, and Tupperware.

Its differentiator is that it is ‘ionised’ to be ‘alkaline’, with a claimed pH of 10. For this, you can expect to pay two to three times as much as you’d pay for regular filtered water in a bottle.
