The ‘Karenification’ of Wellness Is Here

The over-informed wellness consumer is bringing brands to task, according to new NielsenIQ data

There’s a new Karen that has emerged in the wellness aisles, but instead of an “I want to speak to the manager” attitude, she’s scanning barcodes to vet products before they enter her cart.

She’s not being difficult; she’s being thorough. But for wellness brands looking to pull a fast one with non-transparent labeling or inflated claims, she’s the last shopper they want to see.

She is also the consumer at the heart of a new NielsenIQ report on health and wellness trends. NIQ doesn’t gender this shopper, but anyone aware of the consumer space knows that women make the majority of household purchases and health decisions, which makes the skeptical, verify-everything buyer NIQ describes look a lot like her.

More than anything, she’s changing the game. If the squeaky wheel gets the grease, the over-informed consumer is bringing brands to task. They are also serious, considering they are willing to cut back in other areas to devote dollars to wellness goals.

To start, NIQ notes that 62% of consumers say they don’t trust health claims made by food companies. It’s not an entirely surprising statistic, but it has turned shopping from a passive activity to an almost militant act of verification, and consumers have found the tools for the job. 

Wearables like Oura and Whoop are also playing a part in purchasing decisions, actively directing behavior. NIQ found that wearable use is linked to increased water, protein and fresh produce consumption, according to a 2025 survey.

Much like everything else, artificial intelligence is expected to become more involved, leading to an environment where, NIQ says, AI-driven search and recommendation engines may become “trusted intermediaries.”

Though NIQ points out that products still compete on the shelf, they are also now vying for attention within systems that filter, rank and recommend.

“In that environment, clear ingredient labeling, consistent claims and well-structured product data become essential for visibility, as well as trust,” the report notes.

And technology isn’t waiting for brands to take the lead. Label-scanning apps have become a tool that can make or break a purchase decision.

As of January, one in four consumers (nearly a 50% jump in under a year, NIQ notes) were using apps like Yuka, which grade packaged products on nutrition and additives and present an easy-to-understand score. More telling is that 27% of users now trust such apps more than the label itself, and 87% say they will put a product back on the shelf when an app flags it.

Notably, the watchdog instinct has caught the interest of other wellness platforms. In May, Function Health, the celebrity-backed digital health unicorn valued at $2.5 billion, acquired SuppCo, an independent testing platform that spent the past year calling out supplement brands for failing their own label claims. SuppCo’s reports have named names, including an analysis that found several best-selling creatine gummies on Amazon contained little to no creatine.

Winning brands, the report says, are gaining traction with precise functionality, transparent labeling and accessible formats. 

It’s especially occurring in the functional crossover spaces, bringing to mind products like Khloé Kardashian’s Khloud protein popcorn, which scored $15 million in funding or canned beverages for improved sleep, recovery, mental sharpness, energy, a floating feeling from Hiyo or even a good old fashioned high, courtesy of Willie Nelson’s THC beverage brand, Willie’s Remedy+. The VC-backed brand secured $15 million earlier this year to expand into the wellness arena.

Then there’s the GLP-1 of it all. The blockbuster medications have changed how consumers shop, and not in the way retailers first feared. NIQ found that GLP-1 users take fewer shopping trips, down 6.4% year over year, but spend 15.1% more when they do compared to nonusers. For now, they’re a small slice of households (just 4.5%) yet they drove 43% of the sales growth for products carrying muscle health claims.

For brands, it’s not even about being the biggest CPG titan. NIQ notes the advantage shifting toward relevance, agility and proof, and points to its own research showing that innovation remains a critical growth lever, though it adds that innovation is becoming more complex to execute well.

Ultimately, NIQ paints a picture of the death of brand-led in favor of attribute-led and outcome-led and not just jumping on the latest health trend.

Competing effectively, the report notes, demands credibility and consistency, with products that not only meet specific needs but are “supported by transparent ingredients and benefits information that can withstand scrutiny across every stage of the consumer journey.”
