DAO Hist

DAO Hist supplies diamine oxidase enzyme and pine bark extract to support healthy histamine metabolism, intestinal health, and protect against digestive discomfort from histamine foods.

DAO Hist supplies diamine oxidase (DAO), the enzyme that supports histamine metabolism in the digestive tract. Our unique formulation also includes pine bark, a potent free radical scavenger that helps to inhibit the release of histamine from mast cells. Pine bark has also been shown to support the up-regulation of mRNA expression of tight junction proteins and support intestinal health. Taking DAO Hist prior to consuming high histamine foods and beverages helps defend against digestive histamine issues.
