The agreement was signed at By-Health’s factory in Zuhai, China. As the first fully transparent factory in the Chinese dietary supplements industry, it was a fitting location to renew the partnership between two companies with a mutual commitment to transparency and traceability. It was this shared ethos that brought Rousselot® and By-Health together 17 years ago, and later led to the signing of two strategic agreements.

We’re delighted that Rousselot and By-Health are reaching further together in the spirit that Rousselot always seeks to pursue, supporting mutual benefit through close collaboration” said George Liu, CEO of Rousselot China. “The successful, sustained partnership between our two companies has enabled us to bring a range of high-quality health and nutrition products to Chinese consumers. We look forward to building on that success!”

Mr. Liang Shuisheng, Vice-President of By-health said: “With this agreement renewal , we will continue bringing high quality products to the market. The agreement will play a role in educating consumers on the relationship between health and nutrition products, with a deep and positive influence on the industry.”


By-Health is the leading Chinese dietary supplements brand. For more than a decade, they have been committed to their 'Three Step' quality strategy, based on global sourcing of high standard raw materials. By now, they import raw materials from 23 countries worldwide and focus on continual research and development to uncover new raw materials and technologies with innovative applications. In doing so, By-Health aspires to improve the quality of life for all consumers.
