Studio au lac stages launch campaign for chocolate extract by Dieter Meier

With PhytoCacao®Cardio, Zeller is launching the first product in its new dietary supplement line, zeller plus—an innovative formula based on cocoa flavanols designed to support vascular health. The 360° campaign was created by the Zurich-based agency studio au lac.

The special feature of PhytoCacao®Cardio is the patented special epi extract, developed by the Swiss chocolate company Oro de Cacao by artist, musician ("Yello") and entrepreneur Dieter Meier. The extract is obtained from unroasted cocoa beans using a unique, cold-water process. The cocoa flavanols it contains promote the formation of nitric oxide (NO) in the endothelium and thus support vascular elasticity - for healthy blood flow and better supply to organs and tissues.

Each daily dose contains 200 mg of EPI extract, which corresponds to the recommended amount of cocoa flavanols. The launch will be accompanied by a broad-based communication campaign, ranging from strategy, text, logo and packaging to digital design and key visuals.

The cross-media implementation includes DOOH, POS materials, F12 posters, classic ads and social media activations in the form of feeds, stories and reels. The campaign is complemented by programmatic advertising with contextual targeting and direct buys in German-speaking and French-speaking Switzerland.

With zeller plus, Zeller is positioning itself as a modern brand in the herbal health sector and transferring its pharmaceutical expertise to the food supplement market.
