Kalleh introduced Five-Star, the first lactose-free yogurt in Iran, produced with a unique, non-chemical ultrafiltration method. This innovation brought back the joy of dairy for people suffering from lactose intolerance, letting them enjoy dairy products without digestive issues.

Alongside the product launch, we developed an informative landing page featuring a gamified test experience. Users answered a series of lifestyle and health-related questions, and at the end of the quiz, they received a personalized result indicating whether they might be lactose intolerant. Based on the outcome, the platform recommended trying Kalleh’s Five-Star yogurt. This interactive approach combined health awareness with product introduction, engaging over 1,000 participants.
