Schrödinger's Supplement: How Britain's Wellness Aisle Learned to Say 'Quantum'

On a wet Saturday in Leeds, sheltering from a bus that never came, I wandered into a health food shop and met a bottle of water with a physics degree.

It was glass. It was handsome. It cost £27.50. And the label explained, in a confident sans-serif font, that its contents had been ‘quantum-infused’, ‘frequency-aligned’ and ‘structurally harmonised’. I checked the ingredients. Water. That was the list. Water, and a price tag that would make a decent bottle of wine feel inadequate.

I did not buy it. I did, however, spend the next forty minutes reading labels in three shops, which is how you end up writing an opinion piece on a Sunday.

Quantum is a real word, which is the problem

Here is the awkward bit for sceptics: quantum mechanics is not nonsense. It is arguably the most precisely tested theory in human history. It explains why the Sun shines (tunnelling), why your phone works (semiconductors), why flash memory holds data (more tunnelling), and why a lump of uranium eventually warms your tea.

Quantum effects really do turn up in biology too. Protons tunnel in water and ice, which nudges along some enzyme reactions. There is serious research on coherence in photosynthetic light-harvesting, on birds possibly sensing magnetic fields through radical pairs, and on whether olfaction involves vibration-assisted tunnelling. Some of these ideas are strong, some are contested, all of them are interesting.

The trouble is that ‘quantum’ has also become the marketing equivalent of a chef’s kiss. It is a word that sounds like it means something specific while legally meaning almost nothing at all. No regulator owns it. No standards body polices it. Anyone can print it on a bottle, a pendant, a mat, a patch or a £2,400 box that allegedly ‘rebalances your biofield’.

A pocket guide to quantum hokum

After an unscientific survey of high street shelves, online marketplaces and one memorably aggressive kiosk in a shopping centre, I offer you six tells.

• The word does the heavy lifting. If ‘quantum’ appears more often than the ingredients, the product is not a technology, it is a typeface choice.
• No units, no numbers. Real physics has quantities: joules, kelvin, hertz, seconds. Hokum has ‘energy’, ‘vibration’ and ‘alignment’ — words that sound measurable and refuse to be measured.
• The unfalsifiable escape hatch. Ask for a mechanism and you get ‘it works on a level science can’t yet detect’. That is not a claim, it is a shrug with a business plan.
• Consciousness did it. Any sentence containing ‘quantum’ and ‘your intention’ in the same breath is almost certainly rubbish. Observers in quantum mechanics are detectors, not vibes.
• Borrowed authority, unborrowed evidence. A patent number, a satisfied customer, and a certificate from an institute whose address is a lock-up in Slough. The UK’s Medicines and Healthcare products Regulatory Agency does not ‘approve’ supplements, and ‘registered’ rarely means what shoppers assume.
• The price is inversely proportional to the proof. Water is cheap. Water that has been ‘informed by quantum field technology’ is £27.50.

What the rulebook actually says

Here is the genuinely useful part. Britain is not lawless on this. The Advertising Standards Authority’s CAP Code requires advertisers to hold evidence for claims before they run them — rule 3.1 is the one that sinks most pseudoscientific marketing. Health claims get stricter treatment still, and claims that a product can treat or prevent illness are medicinal claims requiring authorisation.

Beyond advertising, the Consumer Protection from Unfair Trading Regulations 2008 make misleading commercial practices a matter for Trading Standards, and the Competition and Markets Authority can act on aggressive or deceptive selling. In practice, enforcement is reactive: someone has to complain, and by then the kiosk has packed up.

So complain. It takes ten minutes on the ASA website, it is free, and it is the most British form of scepticism available: a polite letter that quietly ruins someone’s afternoon.

Don’t let the hucksters have the good stuff

The risk of all this debunking is that we end up flinching at the word itself, treating quantum mechanics as a marketing artefact rather than a genuine strangeness at the bottom of the world. That would be a shame, and it would also hand the hucksters a monopoly they do not deserve.

The real thing is better than the fake thing. It is better that a particle can be in two places until you look — not metaphorically, but in a lab, with lasers, repeatedly, in Oxfordshire. It is better that a kilogram of water contains more tunnelling protons per second than you can comfortably imagine. It is better that the 2022 Nobel Prize went to people who proved the universe refuses to be locally realistic.

None of that requires a subscription. None of it comes in a bottle. Wonder is free; the water is £27.50.

And if a shop assistant asks whether you would like to try the quantum-infused variety, you may now reply, with perfect scientific accuracy, that you will decide when you observe the price.
