Pfizer has acquired Sirio Pharma’s wholly-owned subsidiary, Treerly Health Co., a women’s nutritional healthcare brand in China. The Treerly portfolio expands Pfizer Consumer Healthcare’s products in China with OTC dietary supplements. Pfizer’s Caltrate calcium supplements and Centrum multivitamin supplements are among the top three brands in the OTC vitamin and minerals supplement category in China.

Sirio Pharma is a private contract manufacturing company in China that produces dietary supplements and drug products, and is currently a qualified third-party supplier to Pfizer Consumer Healthcare. Sirio will continue to supply the Treerly family of products to Pfizer.

“The acquisition of the Treerly brand and its family of products will enhance the portfolio of dietary supplements we offer to our retail customers in China and will enable us to help more consumers improve their health and well-being,” said Keith Choy, regional president, Asia Pacific, Pfizer Consumer Healthcare. “The addition of the Treerly products will also make it possible to leverage our existing sales and marketing capabilities and be more efficient in launching future innovations for consumers in China.”
