Histamine Block
Seeking Health
Overview
Histamine Block contains Diamine Oxidase (DAO), an enzyme shown to help break down histamine in the digestive tract. While studies suggest DAO supplementation can reduce symptoms of histamine intolerance, the specific activity level (HDU) of the DAO is not provided, making it difficult to fully assess its potency compared to research benchmarks. The inclusion of Vitamin C at a low dose is unlikely to contribute significantly to the primary function of histamine breakdown.
The Good
Provides Diamine Oxidase (DAO), the primary enzyme for breaking down dietary histamine.
Can effectively reduce symptoms of histamine intolerance in susceptible individuals.
Supports digestive health by reducing the histamine load in the gut.
The Bad
DAO is derived from porcine (pig) kidney, making it unsuitable for vegetarians, vegans, or individuals with pork allergies.
Specific activity (HDU) of DAO is not disclosed, making it hard to compare its strength or determine optimal dosing for efficacy.
Contains sucrose and shellac as inactive ingredients, which some consumers may wish to avoid.
Is it for you?
Best For: Individuals with histamine intolerance, those seeking digestive support
Skip If: You are allergic to pork, have immune-related food allergies, or gluten intolerance.
