The way US consumers engage with health is starting to pull multiple categories into the same orbit. A new NielsenIQ (NIQ) report describes a “convergence effect,” in which food, supplements, beauty and healthcare services are increasingly overlapping as consumers track and manage their health more directly.
Around 70% of consumers now say they are proactive about managing their health, according to NIQ data, with behaviors like increasing protein and fiber intake becoming part of everyday habits rather than direct interventions.
Functional benefits move beyond supplement formats
Protein, fiber and other functional ingredients are extending across the store, from traditional supplement formats into mainstream food, beverage and even adjacent categories. NIQ frames this as a shift away from “removal” toward “addition” and “optimization,” in which products are expected to contribute to health outcomes throughout the day.
“The biggest shift for supplement companies is knowing consumers are no longer thinking in supplement silos, [but] expect protein, fiber ,and functional benefits to be integrated into daily routines just like food and beverage,” Sherry Frey, VP of Total Wellness at NIQ, told NutraIngredients.
That same dynamic is showing up in retail, where assortments are expanding and wellness is being merchandised across multiple touchpoints rather than confined to a single aisle.
Real-time metrics begin to shape consumption
At the same time, consumers are getting more feedback on how those choices affect them.
Wearables and at-home testing are giving users a clearer view of sleep, recovery and metabolic markers, with that information starting to influence what they eat and how they supplement. The report notes that technology is moving from tracking behavior to directing it.
NIQ estimates that 36% of US adults now use a health wearable, and those users “are nearly twice as likely to change nutrition behaviors as they initially intend,” Frey said. “More than half of users report eating more protein, consuming more fruits and vegetables, and reducing sugar as a direct result of wearable feedback.”
As that feedback loop tightens, expectations around products are also shifting. “Consumers will expect products to adapt to their data — responding to changes in sleep, stress, recovery or metabolic markers,” she said.
Performance expectations tighten around outcomes
More visibility into personal health is also changing how products are evaluated. The NIQ report points to a move away from general positioning toward measurable results, stating that wellness will increasingly be judged “not by absence or addition but by impact and effectiveness.”
According to Frey, this means “supplement companies need to prove products actually change outcomes consumers care about,” including connecting product use to real effects consumers can track or feel.
“Brands must communicate benefits in a way that’s concrete and personalized,” she added. “Proof points replace promises.”
GLP-1s add one more layer to shifting demand
Alongside these behavioral and technological changes, GLP-1 medications are beginning to influence how consumers approach diet and supplementation. The report describes GLP-1s as long-term demand shapers, with adoption expanding beyond early adopters into a wider population.
“GLP-1s should be treated as a long-term demand shaper because they permanently change how consumers eat, supplement and think about nutrition,” Frey said.
Changes in portion size and intake are bringing more focus to nutrient density, as well as focused support for areas such as GI health, muscle preservation and energy.
However, even as engagement with wellness increases, access remains uneven. Cost is cited as the leading barrier to healthier choices in the NIQ data, highlighting a gap between consumer intent and purchasing power.
“Cost remains the single biggest barrier to wellness adoption, and that’s also where the next growth opportunity lives,” Frey said.
