Chenodeoxycholic Acid (CDCA) is a primary bile acid naturally present in animal bile (e.g., bile of cattle, sheep, and pigs). It is prepared through modern biological extraction, purification, and refinement processes, meeting pharmaceutical grade and dietary supplement grade standards. Retaining the core physiological activities of natural bile acids, it exhibits properties such as regulating bile metabolism, dissolving cholesterol stones, and protecting hepatobiliary function, with low toxicity and good biocompatibility. As a high-value natural active ingredient, it is widely used in the pharmaceutical industry, dietary supplement sector, hepatobiliary health functional food market, and pharmaceutical intermediate field.
