Bio Essence is a small herbal health and nutrition supplement company based in Irvine, California. The company sells branded herbal and nutritional supplements, with a focus on traditional Chinese medicine products including single herbs, granules, pills, and tablets, as well as formulated dietary supplements and medical food. Bio Essence also provides OEM services, producing supplements for other companies under their own labels. Following a restructuring that involved selling or dissolving all three of its operating subsidiaries between late 2023 and early 2024, Bio Essence now operates directly with just 4 full-time employees, outsourcing all physical manufacturing and acting as an intermediary for its OEM business. Revenue comes from two channels: direct branded supplement sales and OEM/private label services for third-party companies.
