AST Enzymes

AST Enzymes is a U.S.-based private manufacturer and marketer of systemic and digestive enzyme supplements focused on gut, digestive, immune, cardiovascular, respiratory, joint, and general wellness applications. The company describes itself as a research-driven enzyme and probiotics manufacturer that formulates and manufactures products in-house rather than only encapsulating or bottling third-party ingredients. Its portfolio includes branded nutritional supplements such as Serracor-NK, Excellacor, Vida-Defense, ImmunoSEB, digestive enzymes, probiotic products, and single-ingredient enzyme formulations like serrapeptase and nattokinase. AST Enzymes appears to operate in the healthcare and nutrition/nutraceutical segment rather than as a drug-development biotech, with products sold commercially to healthcare professionals and consumers. It also indicates private-label and contract manufacturing capabilities supported by GMP/NSF-certified operations and certified laboratory infrastructure.
