HistaGest-DAO provides supplemental diamine oxidase (DAO), the enzyme responsible for breaking down food-derived histamine, to help support normal and healthy histamine metabolism.* Histamine is a bioactive compound produced in the body in response to an injury or the presence of foreign substances and is present in all foods in the diet in various degrees. Some foods are known to be high in histamines, such as fermented foods and alcoholic beverages. Lower DAO activity may result in higher levels of histamine being absorbed through the small intestine and accumulating in the blood.

Each tablet provides 20,000 histamine-degrading units (HDU) of diamine oxidase (DAO) from porcine kidney extract to promote the degradation of dietary histamines.* HistaGest-DAO is formulated with gastro-resistant, coated tablets with delayed-release technology that allows the DAO enzyme to reach the small intestine where it performs its action. Taking one tablet before each meal promotes the amount of DAO in the small bowel to help break down histamine in the digestive tract and soothe digestive discomfort associated with sensitivity to histamine-rich foods.*

• Support Digestion of Food¢Ã¢€š¬Ã‹Å“Derived Histamines - Lower DAO activity may result in higher levels of histamine being absorbed through the small intestine and accumulating in the blood. HistaGest-DAO provides supplemental diamine oxidase enzyme. Unlike common digestive enzyme products, this enzyme is responsible for breaking down food-derived histamine to help support normal and healthy histamine metabolism.*
• Convenient 'Take-Anywhere' Dispenser - This DAO supplement offers small tablet delivery in a convenient travel dispenser for portability and ease of use when on¢Ã¢€š¬Ã‹Å“the¢Ã¢€š¬Ã‹Å“go.

• Just Take One Before Histamine-Rich Foods - Taking one diamine oxidase DAO supplement tablet before each meal promotes the amount of DAO in the small bowel to help break down histamine in the digestive tract, support digestive health and soothe digestive discomfort associated with sensitivity to histamine-rich foods.*
• Delayed-Release Tablets Designed for High Performance - DAO supplements can be less effective if they do not reach the small intestine. HistaGest-DAO diamine oxidase supplement is made with gastro-resistant, coated tablets with delayed-release technology that allows the DAO enzyme to reach the small intestine where it performs its action.*
