HSO Health Care

HSO Health Care is a Vienna-based biotechnology company specializing in the development of scientifically documented probiotics for women's health. The company is best known for its flagship product, Astarte, a patented probiotic formulation designed to maintain and restore healthy vaginal flora through oral administration. HSO's products are backed by rigorous clinical research and focus on addressing urogenital health issues such as bacterial vaginosis and yeast infections. In 2020, the company was acquired by Chr. Hansen, a global leader in bioscience, to strengthen its position in the rapidly growing women's health market. Following the merger of Chr. Hansen and Novozymes, HSO's technology and product portfolio are now part of the Novonesis group.
