Collection: OmneDiem Best Sellers - Histamine Digest DAO Enzyme Supplements (SHOP)

OmneDiem has been a pioneer in diamine oxidase (DAO) supplements. Our founder discovered and patented the best method of DAO extraction and has managed the clinical testing of DAOgest, a high-quality porcine-derived DAO. 

OmneDiem is committed to transparency and quality by providing evidence of third-party testing and published clinical data to support the efficacy and safety of their product for human use. 

In contrast, some DAO supplements use pea-derived DAO. It is important to note that pea-derived DAO does not have peer-reviewed published clinical data to support the effectiveness in humans. While internal testing is a part of product development, independent clinical studies are the gold standard for substantiating a product's benefits and ensuring it meets the rigorous standards of scientific scrutiny.
