One of the company’s first operational directions was natural substance research. Other directions were developed later and are complementary, enhancing the company’s overall research and development capacity. While developing new functional food products, the company faced challenges related to specific substance availability and insufficient research volume and reliability, crucial for expected mechanisms and effects during product development. Currently, the company performs various bioactive natural substance extraction using microorganisms, medicinal plants, and fungi. The company independently develops active substance acquisition methods and verifies and improves their efficiency. Extract activity and quality are evaluated by company specialists, occasionally using external services. Given the need for quick and targeted tests, infrastructure for in vitro model system development has been created. The company develops real-time in vitro model systems for active substance evaluation and performs cytotoxicity tests. Model systems are based on fully characterized cell cultures. Depending on research objectives, specific cell populations are selected and, upon active substance exposure, their growth rate and structural quantity are determined to characterize substance impact. Company specialists perform tests and interpret results.
