## Overview

Hist Diamine is a powerful histamine blocker featuring 20,000 HDU of diamine oxidase (DAO) in a vegetarian capsule format. Designed to support individuals with histamine intolerance, it promotes skin, rhinoconjunctival, and gastrointestinal health while adhering to strict cGMP quality standards.

## Description

Hist Diamine 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. 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 Diamine 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 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. Genetic and environmental factors may interact to influence DAO expression. Ongoing research addresses the role that genetic variations may play in individual differences in DAO metabolism, and serum activity was significantly associated with seven single nucleotide variations within the DAO gene. Histamine tolerance may be reflected in detailed questionnaires, food intake logs, trial with low-histamine diet, and measurement of DAO and histamine. Hist Diamine does not manage or address antibody-related or IgE-related food allergies.

Review: Really helps me! - Have these on hand, all the time, to take with any meals that I think may contain problem foods (for me). I believe these DAO caps keep me from suffering histamine headaches when I take them shortly before or with a meal of suspect foods.
Review: Similar to Seeking Health brand - If you look closely, most of these supplements with DAO all have pretty much the same ingredients. The biggest difference is price. I have also taken the Seeking Health brand and both seem quite equal to me at stopping reactions. At the time of purchase, the price was the only significant difference.

## Questions & Answers

**Q: Is there an diamine oxidase supplement without all of the toxic fillers? Thanks**
A: I'm sure there must be, but I have not taken the time to search one out.  I don't take that much of this DAO, so I don't worry about the fillers in these small capsules.

**Q: Is there corn in this?**
A: The ingredients list "acetylated corn starch" near the bottom of the list.  So, I guess it does contain a corn derivative.

**Q: What are the inactive ingredients?**
A: other ingredients,    Microcrystalline cellulose, HPMC (capsule), sucrose, ascorbic acid, rice starch, shellac, hydroxypropylcellulose, polyvinylpolypyrrolidone, hydrated magnesium silicate, acetylated corn starch, sodium carboxymethylcellulose, and glycerol.

**Q: Is this product produced in the US?**
A: This product produced in the US
