- 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 produced in the body in response to injury, or the presence of foreign substances. Histamine is present in many foods including 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 causing symptoms.
- Each tablet provides 20,000 histamine-degrading units (HDU) of diamine oxidase (DAO) from porcine kidney extract to promote the degradation of dietary histamines and this formulation is gastro-resistant coated tablets with delayed release technology to allow the DAO to reach the small intestine.
- 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 may help to delay symptoms.
