Who knew there was a substance ten times as hydrating as water? This is one of the many claims made by promoters of "structured water" — and by their many celebrity endorsers. Structured water, they say, is a version of water that's chemically different, and better. The water molecules are arranged differently, which brings a vast array of benefits to the buyer. So if you didn't realize that your regular water isn't quite water enough, well then, today's episode is for you. We're got a rollicking adventure through the worlds of celebrity endorsements; a version of chemistry that is — well, "creative," to say the least; and the psychology behind buying water that is better than water.

It doesn't take long to search the Internet and find products for sale based on the dubious claim of the existence of water that's better than water. The Natural Action Portable Structured Water Unit, selling for $279, is like a little filtering funnel you pour water through. Spend a bit more and get the Vitalizer Plus Vortex Water Revitalizer for $899, which looks like a blender and makes structured water right there on your countertop. Or spend a lot more and get the Natural Action MagnaRay MR-24 Whole House Unit for $2,999, which looks a lot like the little inline filter you might have going to your refrigerator's ice maker.

If you don't want to make it yourself, quite a few companies — such as Ed Hardy, Defiance, and Mindful — sell bottled water they claim has already been structured for you. You can even make your own the lazy man's way: buy glass bottles from Flaska for $50-100 apiece, fill them with tap water, and they'll use "vibrational structuring technology" to "energize" it in as little as five minutes.

The basic premise behind structured water is one of the hallmark red flags of pseudoscience, and that's the raising of an alarm that there is something wrong with the status quo. In this case, the status quo is regular water. Whether from the tap or from the bottle, regular water is said to be chaotic or dead. And, strictly speaking, these are both true. Water is certainly not a living organism, so it could be said to be dead — though non-living might be a better word choice. It's also chaotic, in that it is a liquid; and in any liquid, the molecules are loose and jumbled and free flowing. Liquid has a defined volume, but no defined shape; it can flow into any shape precisely because its molecules are unstructured.

But structured water — so the claim goes — has its molecules arranged into a particular ordered pattern. This is usually described as a hexagon. (And — just to be absolutely clear — this is not a real thing. Water does not, and cannot, behave this way; and we'll talk more about that.) In some versions of the claim, six regular water molecules are arranged in a hexagon: the six big oxygen atoms are the points of the hexagon, and each has its two hydrogen atoms hanging off of it in such a way that they don't interfere with each other. In other versions, they call it H₃O₂ (instead of plain old H₂O), asserting that each of the water molecules has both an extra hydrogen and extra oxygen atom. Some also call it coherent water, primary water, magnetized water, crystalline water, hexagonal water, or informed water. Often they come up with derogatory names for real water such as uninformed water or depleted water.

As you can probably guess, the health claims made for drinking this very special water are endless, and almost always too vague to be falsifiable or testable. It's said to enhance your cellular hydration and energy; to facilitate better nutrient absorption and detoxification; to provide anti-inflammatory and immune system benefits; to confer improved digestion, skin health, and weight loss; and my favorite, that it "resonates with the energetic vibrations of your body to amplify your life force."

Claims of hexagonal water structure are not new. Sixteen years ago, I talked about them here in Skeptoid #139, when people selling equally pseudoscientific alkaline water machines claimed their water came in hexagons also. But since then, it found a new booster in science, and has flourished anew. In 2013, Dr. Gerald Pollack, a professor of bioengineering at the University of Washington, published a mass market book called The Fourth Phase of Water, which discussed his legitimate and significant 2003 finding that water pushes away objects such as plastic microspheres from the region close to a hydrophilic surface. He has postulated several speculative mechanisms to explain this, including what he discussed in his book: the conjecture that this so-called exclusion zone water (or EZ water) has the extra atoms in each molecule. This fanciful claim by a real scientist was all the scam artists needed to gild their old alkaline water machines and rebrand them as structured (or EZ) water machines; and now celebrities such as Kourtney Kardashian and countless wellness influencers — who lack the science literacy to know any better — promote these devices as miracle health machines.

There are several ways in which real water molecules can and do form into clusters. Liquid water has thermal energy that manifests as molecular motion. As these molecules move and collide, hydrogen bonds are constantly forming and breaking on femtosecond to picosecond timescales. Water molecules also arrange into transient tetrahedral networks, rings, and chain-like structures that persist for similarly brief periods. Under unusual conditions, water molecules can exhibit different behaviors—such as when confined to nanoscale spaces or in the presence of hydrophilic surfaces, as Pollack discovered with exclusion zones. Researchers have used lasers and other methods to temporarily alter water's structure, but it invariably recovers within picoseconds due to rapid thermal motion. In short, while water molecules are constantly forming dynamic associations and structures, all of these arrangements are extremely fleeting — lasting at most picoseconds rather than the permanent structures claimed by structured water proponents.

But that's only one reason the so-called "structured" H₃O₂ water doesn't actually exist. That molecule is certainly possible and it's real (its chemical name is hydroxide ion hydrate); for example, it appears in some metal complexes where it connects metal atoms. But in normal aqueous conditions, it is extremely unstable and would rapidly decompose into more stable compounds like H₂O₂ and H₂O (hydrogen peroxide and water). Hydrogen peroxide is extremely toxic. If you somehow drank something which then decomposed into hydrogen peroxide, you would be in for a very painful and fast death. Nobody has yet died from drinking the product of their structured water machine, at least not that we know of; so we can be pretty sure that H₃O₂ is not coming out of these devices.

But let us take the responsible path, and not dismiss structured water machines based on their claims alone, but rather upon the test results. So let's go to PubMed and search for trials of having people drink structured water to treat some health condition, or even for general wellness, and see the effects. Hmm. I only found one(!!), and it's for animals: "Structured water: Effects on animals" published in the Journal of Animal Science in 2021. It's a review of 20 years of studies that exposed water to magnetic fields and then had laboratory and farm animals drink it. From the paper's conclusion (perhaps the vaguest I've ever seen):

A magnetic field strength of 1,000 to 3,000 G is required to generate water capable of exerting beneficial effects, while waters treated with field strengths greater than 5,000 G may result in detrimental effects... The animal research conducted to date consistently demonstrated beneficial effects of [structured water] consumption. Additional research is needed to demonstrate how these effects occur, and if these types of [structured waters] are safe to consume and use over the long term.

The paper was written by a Michael I. Lindinger who does business as The Nutraceutical Alliance Inc. In his acknowledgements, he states that it was "part of a larger paid research contract... by Defiance Brands, Inc." Who are they? Well, recall back to the top of the show when we listed some products currently on the market. Defiance is one of the companies selling bottled structured water. Big surprise.

But no papers about anyone testing it on humans? The reason is probably very simple: none of the claims made are specific enough to be testable; and if they were, the tests would fail. As there is no such thing as "structured water" you'd be testing water against water as a treatment for something as vague and meaningless as "enhanced cellular energy". What person with a scientific reputation they care about is going to submit that paper for peer review? They'd never hear the end of it.

We're nearly at the point where we've run out of things to say about the claims of structured water, but there are still two points worth covering. First of all, let's look at some more of the red flags of pseudoscience this product throws down:

• The Appeal to Nature fallacy. If it's natural, it must be safe and healthy and good for you. A number of these products use terms like "pristine mountain spring water".
  
  
• The number of wellness benefits found on all these companies' websites collectively probably rivals the Bible in length. And as we've seen a hundred times before here on Skeptoid: Products claiming to treat everything probably really treat nothing.
  
  
• The use of personal testimonials, including influencer and celebrity testimonials, instead of presenting evidence.
  
  
• There is no theory supporting a mechanism for structured water to be beneficial to the body, inasmuch as nothing meeting any consistent definition of structured water exists.
  
  
• Pollack's book was a published mass market book, not a scientific journal article. This means it had no obligation for peer review or to factual accuracy. It simply had to be popular.
  
  
• Lots of crazy sciencey-sounding jargon: meaningless to the scientist, but impressive to the layperson who also happens to be the customer.
  
  
• These products nearly all have paid social media influencers and affiliate marketing programs. You know, like real sciences don't.

But we could go on like this all day. Let's move on to our second final point, which is the psychology behind a person who wants to buy a product like this. Understand that psychology, and learning what levers to pull, are critical components to successfully marketing and selling pseudoscientific products like structured water.

• The value of community. People love to belong to a community of like-minded people; marketers love community echo chambers where everyone thinks the same way and believes whatever their peers say.
  
  
• Distrust of conventional medicine and science are always going to be popular and people love the feeling of having special insight into the "suppressed truth". Embrace of products like this that contradict established science is psychologically fulfilling and confers a nice little dopamine hit.
  
  
• Confirmation bias thrives in wellness communities — as it does in nearly every community.
  
  
• The feeling of buying a premium product — such as paying nearly $3,000 for a water filter indistinguishable from a $10 one on Amazon — confers a sense of power and superiority.
  
  
• Even without the power and superiority, many people genuinely accept that something more expensive must necessarily be better.
  
  
• Making any lifestyle change induces the placebo effect. I've done something, I've added this device to my drinking water, therefore I expect to feel better.
  
  
• Confusion of correlation with causation will be a feature of wellness products until time immemorial. Anytime these customers feel energetic or happy, they're likely to credit the structured water. And regression to the mean is what happens when any injury or illness heals naturally; and yet our fallible human brains prefer to give the credit to some recent lifestyle change.

In fairness, nearly any intelligent adult human is susceptible to most or all of these frailties. And when we consider that the average adult knows or cares nothing at all about molecular chemistry, and knows nothing about the reasons to research sources or even understands the need to do so, we can hardly blame the victims. Blame for scam pseudoscientific products should always lie upon those selling them, because they are the people who have an ethical (if not a legal) responsibility to ensure the validity and efficacy of their products.

Anyway, that's your skeptical analysis for today. Stay curious, stay hydrated, and always be skeptical.
