Hist-D 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.
Hist-D 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. The active ingredient in Hist-D 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. 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. Certain drugs may affect histamine balance in the body by promoting histamine release or inhibiting DAO.*
Histamine Tolerance Histamine tolerance may not be the same for everyone. Results of a double-blind, placebo-controlled crossover study suggest that tolerance to histamine can vary from individual to individual. Total body histamine load must be considered when evaluating histamine tolerance, and a balance between histamine and DAO appears to be crucial to maintaining skin, rhinoconjunctival, and gastrointestinal health.
