FHIRST Living Soda

FHIRST positions itself as a 'living soda': each drink contains probiotic cultures that remain stable at room temperature, removing the need for refrigeration before opening. The drinks are sugar-free, sweetened instead with a blend of stevia and erythritol, separating FHIRST from mainstream sodas in both formulation and positioning. The brand launched its initial range in 2022, targeting gut-health-conscious consumers who want a sparkling drink without the sugar load typical of conventional carbonated soft drinks.

FHIRST is a member of 1% for the Planet, committing a portion of its revenue to environmental causes. Headquartered in London, the brand operates within the growing functional drinks market, where probiotic and low-sugar formats have attracted sustained consumer interest. The ambient stability of the probiotic cultures is a specific technical point of difference from refrigerated kombucha and similar fermented drinks, which typically require a cold chain throughout distribution.

FHIRST suits fitness-focused drinkers and those managing daily sugar intake who want a sparkling, probiotic drink with genuine functional credentials. The brand is available direct-to-consumer and through specialist retailers.
