New categories of beverages, including "functional" sodas and clear protein drinks, are increasingly appearing in retail aisles as advancements in flavor science and changing consumer habits reshape the industry. Companies like Flavor Man, a beverage development laboratory based in Louisville, Kentucky, and Chicago-based market researcher Mintel report that these products often incorporate additives such as fiber, adaptogens, probiotics, and whey protein isolate. While traditional beverages historically focused on a few major brands and flavors, industry analysts say the market is now shifting toward specialized options that claim to offer health benefits alongside hydration.
The increase in variety is driven in part by developments in flavor science and supply chains. Tom Gibson, chief flavorist at Flavor Man, stated that flavor scientists now have access to a significantly larger palette of aroma chemicals than they did two decades ago. These chemicals, which are the building blocks of flavor, are being isolated from plants using new scientific techniques or produced via bacteria. This expanded access allows laboratories to design "fantasy flavors" or replicate exotic fruit profiles that were previously difficult to manufacture or maintain in processed drinks.
A specific growth area is the "clear protein" sector, which moves away from traditional thick, creamy shakes toward transparent, carbonated formats. Mintel researcher Alex Beckett described this as a technical leap that combines wellness ingredients with the traditional appeal of soft drinks. Several companies have recently launched products in this category: BellRing Brands offers a sparkling soda with 15 grams of whey protein, while USANA Health Sciences subsidiary Rise Wellness has introduced "Protein Pop Balance," a prebiotic soda containing 10 grams of clear whey protein, 5 grams of collagen, and 5 grams of fiber.
Other major food companies are also entering the functional beverage space. Nestle Health Sciences, through its Vital Proteins brand, has introduced a collagen sparkling water marketed for skin health. These products often target "home-hacking" consumers who have previously created their own "dirty sodas" by mixing protein supplements with existing carbonated drinks. According to Mintel, when consumers create their own versions of products, it signals that market demand has not yet been met by existing retail options.
The scale of this shift is reflected in the work of design firms like Flavor Man, which has helped launch tens of thousands of new beverages over the last 30 years. The rise of these drinks affects the operations of large-scale suppliers like whey and collagen producers, who must now race to catch up with the demand for "clear" versions of their ingredients. For small-business owners and retailers, the challenge lies in managing the "rainbow wall" of options that compete for limited shelf space, as specialized sodas for focus, sleep, or digestion displace older, established brands.
Next steps for the industry involve further refining these "functional" recipes as consumer palates adapt to more complex flavor profiles. In the coming months, more brands are expected to expand into these categories, following the precedent set by Nestle and BellRing Brands. While new products like the Dubai chocolate Pepsi or cosmopolitan-flavored seltzers have already reached markets, laboratories continue to develop weirder flavors and new ways to incorporate supplements like adaptogens and probiotics into stable, shelf-ready formats.
