Zeyuan is a nationally certified high-tech enterprise. It specializes in the production and R&D of a variety of microalgae-based health products, including Chlorella powder, Euglena powder, Haematococcus powder, Spirulina powder, and Chlamydomonas powder. The company also develops deep-processed derivatives such as microalgal tablets and bioactive compounds like paramylon and astaxanthin.

Zeyuan is one of the world’s most reliable and high-quality microalgae producers.

In 2019, the company achieved a breakthrough by transitioning the mass cultivation mode from traditional “facility-based agriculture”（photoautotrophic cultivation in open race ponds）to fully industrialized large-scale cultivation（Heterotrophic cultivation in fully enclosed GMP-grade bioreactor）—successfully overcoming two major bottlenecks of photoautotrophic cultivation that have long hindered the microalgae industry: low product quality (high levels of heavy metals and microbial contamination) and low production efficiency.

Currently, Zeyuan has achieved industrial-scale production of both Chlorella powder and Euglena powder as well as Haematococcus powder, with an annual output of nearly 1,000 tons in total. Other microalgae under active development include Chlamydomonas and Spirulina.

Zeyuan’s products are exported to markets across North America, Europe, Australia, Southeast Asia, and beyond, making the company the world’s largest producer of eukaryotic microalgae.

In February 2025, Zeyuan successfully passed an on-site inspection by the U.S. FDA. The FDA on-site audit praised Zeyuan’s performance as “incredibly well done” and confirmed that the company passed their inspection without the need for issuing Form 483, a rare and significant acknowledgment of both compliance and quality.

“ZIONBIO”is the flagship brand of Zeyuan. The brand is guided by a simple yet powerful philosophy on food quality:“The food we produce should be good enough for ourselves — something we can confidently take home to our parents and children. That’s what we call true quality.”
