AST Enzymes offers healthcare professionals and consumers a natural, safe and highly effective therapeutic alternative for preventative care and health. AST Enzymes is a true enzyme manufacturer: one that formulates and creates enzyme supplements, not simply encapsulates and bottles them. We have more than 50 years of enzyme experience, and a master formulator who created many of the original systemic enzyme formulas on the market today. In addition, we test our products at our in-house laboratory for the highest purity, quality and efficacy.
