Key takeaways

  • In 2024, the U.S. Nuclear Regulatory Commission warned that some wristbands and pendants sold with “quantum energy” and “scalar energy” claims contained uranium and thorium, and told owners to throw them away.
  • Changing your diet can shift your urine’s acidity by up to about one unit on the pH scale, but it moves blood pH by only 0.01 to 0.02 units, because your kidneys hold it steady.
  • The National Center for Complementary and Integrative Health says there’s no scientific evidence that the energy field described in Reiki exists, though Reiki hasn’t been shown to cause harm.
  • “Clinically proven” is a claim regulators enforce: the FTC says marketers must have the level of proof they claim, which for health benefits generally means randomized human trials.
  • When a product uses a science word, ask what it means to a scientist, whether anyone measured it, and whether the product itself was tested in people.

In October 2024, the U.S. Nuclear Regulatory Commission (NRC) published an unusual consumer warning1. It wasn’t about a power plant. It was about wellness jewelry, pillows, yoga pads and even kinesiology tape.

These products were sold with promises of “negative ions,” “scalar energy,” “quantum energy” and support for the “biofield”1. Testing by Oak Ridge National Laboratory found uranium and thorium in some wristbands and pendants, at levels high enough to require a radioactive materials license1. None of the products had been licensed1.

The NRC judged the whole-body dose from a pendant or wristband as likely low. But it warned that wearing one constantly could raise the dose to your skin1. Its advice was blunt: “our best advice is to throw them away”1. In the U.S., they can go in household trash with no special handling, the agency says, advice still on its page as of September 20261.

That case is extreme. The pattern behind it is everyday. Real scientific words get borrowed to sell things that a physicist or chemist wouldn’t recognize.

This glossary isn’t about mocking anyone’s experience. People do feel calmer after a Reiki session or refreshed after a glass of water. The question is narrower: when a label names a scientific mechanism, does that mechanism exist, and was the product tested?

Science words sell because they sound like proof

The Federal Trade Commission (FTC) knows this tactic well. Its 2022 Health Products Compliance Guidance, which replaced a 1998 guide for supplement marketers, spells out how it works2.

Lab coats, microscopes and references to medical journals can give an ad “an impression of scientific legitimacy,” the FTC says2. Phrases like “medical innovation” or “research center,” paired with medical images, can falsely suggest a product is backed by proof2. Softening words like “promising” or “preliminary” usually don’t undo that impression2.

The core rule is simple. Marketers must have at least the level of support they claim to have2. A science word on a label is a claim, and you’re entitled to ask what supports it.

The glossary: ten words, two meanings

The middle columns show the gap between lab and label. The last gives you a question to ask.

Word What it means in science How wellness marketing uses it Ask this
Quantum The physics of atoms and tiny particles, where energy comes in fixed packets Pendants, bedding and yoga pads said to carry “quantum energy”1 Which quantum effect, measured how?
Frequency How many times a wave repeats each second, measured in hertz Devices said to match and destroy a disease’s “frequency”4 Was this device tested on this disease in people?
Vibration Physical back-and-forth motion, like a plucked guitar string “Raise your vibration” with foods, oils or crystals Is this a feeling or a measurement?
Energy The ability to do work, measured in units like joules or calories A life force that can be blocked, balanced or passed through the hands7 Has an instrument ever detected it?
Biofield No settled scientific meaning; the body does make real electrical signals, like a heartbeat on an ECG An invisible healing field a practitioner can sense and adjust17 Has the field been measured reliably?
Scalar energy, negative ions “Scalar” means a quantity with size but no direction; ions are charged particles Mineral-filled jewelry and pillows said to emit healing energy1 What mineral is inside?
Alkalize Raise the pH, a 0-to-14 scale of acidity Foods, waters or drops said to make your body less acidic3 Blood or urine?
Structured water Water molecules link by hydrogen bonds that break and re-form in trillionths of a second10 Water “restructured” by vortex or other devices into a healthier form10 How could a structure last?
Epigenetic reprogramming Chemical marks on DNA, such as methylation, that help control which genes are used11 Supplements or programs said to “reprogram” your genes Which marker changed, by how much, and did health improve?
Clinically proven Shown to work in well-designed human trials A product, or one ingredient, was tested once, somewhere2 Which trial, of this exact product, for this claim?

“Alkalize”: your food changes your urine, not your blood

Alkaline-diet promoters argue that modern diets make the body acidic and cause disease, including cancer3. Researchers Tanis Fenton and Tian Huang tested that idea in a 2016 systematic review in BMJ Open3.

They screened 8,278 citations and found just one study that fit their criteria3. It followed 27,096 male smokers and found no significant link between a more acid-forming diet and bladder cancer3. They found no randomized trials, and no studies at all on alkaline water and cancer3.

The numbers explain why. Across studies, diet changes shifted urine pH by 0.2 to 1.2 units, but blood pH by only 0.01 to 0.02 units3. Your kidneys excrete extra acid to keep your blood steady3. So a test strip dipped in urine tells you about your recent meals, not your blood.

The idea has a grain of lab science. In lab and animal studies, the fluid around tumors is less able to buffer acid than normal tissue. The reviewers called that an early hypothesis that shouldn’t be applied to people3. They concluded that the evidence doesn’t justify promoting alkaline diets or water to prevent or treat cancer3.

There’s good news for anyone who eats this way. Many of the fruits and vegetables these diets favor may still help guard against cancer, the reviewers wrote. If they do, the credit likely goes to their nutrients and plant compounds, not to any effect on pH3.

Keep the produce. Skip the test strips and the pricey water.

“Frequency” and “vibration”: radio waves don’t shatter disease

Frequency is real and measurable. Medicine uses it every day, in ultrasound and MRI scanners.

The marketing version starts with the Rife machine, built in the 1920s by an American, Royal Raymond Rife. Its supporters say every medical condition has its own electromagnetic frequency, and that a matching impulse can kill diseased cells, Cancer Research UK reports4.

The charity found no reliable evidence that the machine treats or cures cancer, and noted that most claims online are personal stories4. Some users have reported electrical shocks and rashes4. Back in 1994, an American Cancer Society report pointed out that sound can shatter glass, but radio waves can’t destroy bacteria, PolitiFact noted in a 2022 fact-check5.

The FTC has acted on frequency claims. In 2002, BioPulse International agreed to settle charges over treatments it sold cancer patients at a clinic in Tijuana, Mexico: an “Acoustic Lightwave Therapy” based on Rife technology, and insulin injections meant to “starve” tumors, at up to $39,9006.

The FTC said BioPulse lacked support for its safety and effectiveness claims. The proposed settlement, subject to court approval, barred unsupported claims and included a suspended $4.3 million judgment6.

Researchers do study radio frequencies against cancer. A University of Alabama radiation oncology professor emeritus told PolitiFact that some frequencies have shown favorable early results, and that patients shouldn’t give up proven treatment for an unverified one5. Cancer Research UK notes that a small liver cancer study used different frequencies from Rife machines4. The honest question is always which frequency, tested how, and in whom.

“Raise your vibration” usually describes a mood or a spiritual state, and as a description of how you feel, it can be meaningful. It becomes a problem when a product claims to physically retune your body.

“Energy” and “biofield”: a real experience, an unmeasured field

In physics, energy is something you can measure. In many healing traditions, energy means a life force, like qi in traditional Chinese medicine. The National Center for Complementary and Integrative Health (NCCIH) describes qigong as an ancient Chinese practice aimed at optimizing energy in body, mind and spirit8. It describes the research on its benefits as conflicting or limited, though qigong appears safe8.

A Reiki practitioner rests their hands gently on you, or holds them a little above your body, aiming to channel healing energy7. NCCIH, on a page last updated in December 2018, says science has found no sign that the energy field at the heart of Reiki exists7.

Most Reiki studies have been of low quality and have disagreed with one another, and NCCIH says no health benefit has been clearly shown7. No harms have turned up either7.

Not every review reads the evidence the same way. A review released in 2009 by Shamini Jain of UCLA and Paul Mills of UC San Diego looked at 66 clinical studies of Reiki, therapeutic touch and healing touch9. It called study quality average, yet rated the evidence as strong for easing pain intensity in people outside hospitals9. NCCIH’s later summary is more cautious7.

Many healing traditions used “energy” to describe vitality and balance long before modern physics existed. Respecting those traditions doesn’t require dressing them in physics they never claimed. Gentle touch, focused attention and quiet time can help people feel better, and those experiences are real.

The trouble begins when “energy” claims replace care for a serious illness. If you enjoy Reiki or qigong, NCCIH encourages you to discuss your care decisions with your health care provider7.

“Quantum,” “structured water” and “epigenetic”: real science, stretched

Quantum. Quantum physics describes how atoms and particles behave, and it underlies lasers and computer chips. The NRC said it couldn’t tell whether the “quantum” products worked as advertised, only that some were radioactive1. Our article on EMF products covers similar pendants banned in the Netherlands.

Structured water. In 2024, AAP FactCheck asked chemists about claims that “structured” or “hexagonal” water hydrates better and can be made with special devices10. Timothy Schmidt, head of chemistry at UNSW Sydney, said such a material doesn’t exist10. Dan Preston of the Australian National University explained that the bonds between water molecules break and re-form within about a trillionth of a second, too fast to hold a lasting shape10. Water in fruit is ordinary water, though fruit brings nutrients10.

Epigenetic reprogramming. Epigenetics is real and young. It studies chemical marks on DNA, such as methylation, that help control which genes are used. A 2024 NIEHS report described identical twins in which only one had lupus and the twins’ methylation differed11. Metals, pesticides and smoke can alter these marks11.

Changing them on purpose is harder than ads suggest. In a trial called CALERIE, 220 adults without obesity were randomly assigned to cut calories or eat normally for two years12. They aimed for a 25% cut but averaged about 12%12.

One methylation measure showed a pace of aging about 2% to 3% slower, and two others showed no change12. The authors called the effects small and said long-term effects on disease are unknown12.

Unlike “quantum” or “energy,” this phrase has been tested in court.

In January 2013, the FTC ruled that POM Wonderful and its owners had deceptively advertised pomegranate juice and POMx supplements in 36 ads and promotions13. The ads claimed the products could treat, prevent or reduce the risk of heart disease, prostate cancer and erectile dysfunction, and the FTC found no adequate support for claims that they were clinically proven to work13. The order required two randomized, well-controlled human trials before future disease claims13.

In 2015, a federal appeals court upheld the need for randomized trials to back disease claims. It found that requiring two trials was not justified in that case, the FTC’s guidance notes2.

The FTC’s guidance gives more examples. A brain-training company claiming its software is clinically proven to improve memory can’t rely on a study that only tested a narrow working-memory task2. “Clinically tested ingredient” implies the tests showed a benefit2. Customer surveys and stories are never enough, and animal or test-tube studies alone don’t count2.

When you see the phrase, ask whether the trial tested this exact product, at this dose, for this claim, in people like you. Then ask who paid for it.

What the evidence says

Claim Evidence level Basis
Alkaline foods or water change your blood pH in a meaningful way Evidence says no, or unsafe Diet moved blood pH by 0.01 to 0.02 units across studies3
An alkaline diet prevents or treats cancer Not enough evidence One observational study found no link; no trials3
Rife-type frequency devices treat cancer Evidence says no, or unsafe No reliable evidence; shocks and rashes reported; FTC action46
Reiki works by moving a measurable energy field Not enough evidence NCCIH: no scientific evidence the field exists7
Touch-based energy therapies ease pain or anxiety Promising but early A 2009 review rated pain evidence strong; NCCIH calls most Reiki research low quality and inconsistent79
“Quantum” or “scalar energy” jewelry improves health Evidence says no, or unsafe The NRC can’t say they work; some held licensable uranium and thorium1
Water can hold a lasting “structured” form Evidence says no, or unsafe Chemists say bonds re-form within about a trillionth of a second10
A product can reprogram your epigenome to reverse aging Not enough evidence Two years of calorie cutting changed one measure slightly12

How to check a science word, and where to report

If a product fails two or more of these checks, treat its science words as decoration. That doesn’t make it worthless, but its price shouldn’t depend on a mechanism nobody has shown.

To report a misleading health claim, use the FTC’s site, ReportFraud.ftc.gov. If a device or product hurt you, report it to the FDA through MedWatch. If you own a “negative ion” item, the NRC’s advice as of September 2026 is to throw it out with ordinary trash. If you keep it, the agency suggests less contact time, more distance, and wearing pendants over clothing1.

Questions readers ask

Is it wrong to use words like “energy” or “vibration” to describe how I feel?

No. Those words can describe real experiences, and many traditions have used them for centuries. The line is crossed when a seller claims the words name a physical force that a product can measure, move or fix.

If Reiki helps me relax, should I stop?

NCCIH hasn’t found Reiki harmful, though it hasn’t found it clearly effective either7. If it helps you relax, that experience is yours. Just don’t use it in place of care for a serious condition, and tell your clinician about it.

How can I check whether “clinically proven” is true?

Ask the company for the study. Check that it tested the same product and dose in people, compared it with a placebo or other treatment, and measured the benefit being advertised2. If the answer is a study of one ingredient in mice, the claim is stretched.

Why do regulators allow these words at all?

Most of these words aren’t banned. The FTC judges the overall claim an ad makes, and it requires proof for health claims however they’re worded2. That makes your own questions a useful first line of defense.

The bottom line

Science words carry the authority of the lab, which is exactly why marketers borrow them. Some, like quantum and frequency, have precise meanings that rarely match the label. Others, like biofield and structured water, describe things no instrument has reliably found.

Your experiences with touch, rest, water and good food can be real and worth keeping. When a product says it works through physics, chemistry or genetics, ask for the same thing any scientist would: a measurement and a test in people.
