Histamine Shield MD is a patented enzyme formula containing diamine oxidase (DAO)—the main enzyme responsible for the degradation of ingested histamine.

This enzyme has been clinically tested and found to break down food-derived histamine in the digestive tract. DAO is not absorbed and does not have systemic activity.

Histamine Shield MD does not manage or address antibody-related or IgE-related food allergies.*

Histamine/DAO balance Endogenous and exogenous histamine must be broken down in order to maintain homeostasis and histamine balance.

The enzyme diamine oxidase (DAO) degrades histamine by converting it from 2-(4-imidazolyl)- ethylamine to the inactive metabolite imidazole acetaldehyde.[2]

The active ingredient in Histamine Shield MD is porcine- derived diamine oxidase, and research suggests that DAO derived from porcine kidney appears to have identical action to DAO derived from porcine intestine.[3]

In humans and other mammals, DAO is found in high concentrations in the gastrointestinal mucosa. Animal studies suggest that circulating DAO may be a marker for mucosal integrity and maturity.[4]

Certain drugs may affect histamine balance in the body by promoting histamine release or inhibiting DAO.*[2]
