Functional Beverages Boom as Brands Chase Health-Conscious Consumers

From protein coffee to CBD soda, brands are rapidly expanding functional drink lines. Starbucks reports protein cold foam rivaling flat white sales in EMEA.

A sweeping shift in consumer drinking habits is reshaping the global beverage industry, as brands race to pack their drinks with proteins, adaptogens, and cannabinoids to meet surging demand for health-forward options. The functional beverage category has moved well beyond niche wellness circles and into mainstream menus and retail shelves across the United States and Europe.

Starbucks is among the most prominent names riding this wave. Sam Henderson, the coffee giant's EMEA Manager of Beverage Development, told CNBC that protein cold foam has become a breakout performer — selling at volumes nearly comparable to the classic flat white, one of the chain's most established espresso drinks. That comparison signals just how rapidly consumer preferences are shifting toward beverages that promise more than a caffeine fix.

Analysts and industry observers suggest the functional beverage boom reflects broader post-pandemic priorities around wellness, immunity, and fitness.
