The line between snacks, supplements and wellness products is getting blurry
The snack has – had – a fairly simple job description: taste good, satisfy hunger for a while, provide some indulgence between meals, or all of the above.
But today, if the numbers are any guide, consumers increasingly expect much, much more.
A growing share of shoppers want their snacks to deliver some tangible benefit – beyond calories and convenience. They want protein to keep them full, fiber to support digestion, probiotics for gut health, electrolytes for hydration, or ingredients that promise energy, focus, recovery, or overall wellness.
In short, they’re looking for their snacks to do something – and we’ll talk about what that “something” is in a moment. That shift is arguably one of the most important developments in grocery merchandising in recent history.
What once lived primarily in the supplement aisle is starting to show up in cookies, chips, gummies, popcorn, yogurt, beverages, and snack bars.
The result is a category that sits somewhere between traditional snacking… and nutrition and preventive wellness.
And it’s getting very big, very quickly.
According to Fact.MR, the global functional snacks market was valued at roughly $112 billion in 2024 and is projected to more than double to $268 billion by 2035. At the same time, the broader functional foods market is expected to approach an eye-popping $1 trillion globally within the next decade.
They’re Reaching for Snacks to Get It Done
Pushing that growth is a consumer desire, as we said, to have their foods “do something.” And that something turns out to be: addressing specific goals.
Protein is a great example.
Its appeal nowadays goes well beyond athletics and bodybuilding. Consumers increasingly associate protein with satiety, weight management, healthy aging, and sustained energy throughout the day. That’s what they’re going after.
For busy shoppers, a protein snack can serve as a bridge between meals, a meal replacement, or a way to avoid the energy crashes often associated with more carbohydrate-heavy snack options. Growing interest in GLP-1 medications has added another dimension, as many nutrition experts encourage users to prioritize protein intake to help preserve muscle mass while losing weight.
In effect, protein has evolved from a niche sports-nutrition ingredient into a mainstream wellness ingredient, one that appeals as much to office workers, parents, and older adults as it does to gym-goers.
As a result, researchers project the U.S. protein snacks market will grow from approximately $1.8 billion in 2025 to $4.2 billion by 2035.
Protein, however, is increasingly becoming just the entry point.
Industry observers point to gut health as the next major growth opportunity.
It’s been reported that some experts now describe fiber as “the new protein” as consumers become increasingly focused on digestive wellness and the microbiome. Understandably, current innovation efforts are centered on combining probiotics, prebiotics, and other gut-health ingredients into everyday foods and snacks. You can expect advertising to follow accordingly.
After all, customers are beyond interested here…
These Consumers Are Extremely Engaged
Industry reporting found that online searches and social engagement around protein have risen nearly 98% year-over-year. Interest in oats jumped more than 700%, while searches related to adaptogens and collagen each increased by more than 1,000%, reflecting growing consumer interest in functional ingredients associated with energy, recovery, stress management, and overall wellness.
Importantly, though, consumers are not willing to sacrifice enjoyment in pursuit of functionality.
That may be the most significant development of all.
For years, healthy snacks often asked shoppers to compromise. Products delivered nutritional benefits… but frequently lacked the taste and texture consumers expected from traditional snacks. Anyone who’s eaten an “energy bar” in the past 15 years can attest to that.
This emerging generation of products is taking a different approach.
Research has recently highlighted the industry’s push toward products that combine indulgence and functionality, citing examples such as probiotic-enhanced chocolate and snacks that deliver meaningful nutritional benefits while, critically, maintaining familiar flavors and formats.
Other industry observers have described the movement as “pleasure with purpose” — products designed to satisfy cravings while simultaneously supporting health goals. The wellness-and-indulgence aspect of it all gives pressed consumers justification for what is, at the end of the day, a discretionary purchase.
The implications for retailers extend far beyond the snack aisle.
As we’ve seen, functional products are blurring traditional category boundaries. A protein cookie may compete with conventional cookies, sports nutrition products, breakfast foods, and meal-replacement bars. One shopper might see a prebiotic beverage as a soft drink; the person next to them may consider it a wellness product.
The merchandising challenge, then, is to accommodate the wider scope of consumer intent – whether they’re looking for a snack… or an outcome… or both.
Whether that outcome is satiety, digestive health, hydration, energy, focus, or recovery, consumers are demonstrating a growing willingness to pay for products that promise to help them achieve it.
