Im reading all about histamine intolerance and looking for answers for my daughter.

One thing to research is Diamine Oxidase (DAO) insufficiency. I want to try DAO supplements for her. Basically the DAO degrades the excess histamine instead of just blocking the H1 and H2 receptors from using it. From what I gather if you still have excess histamine floating around it can still be taken up by H3 and H4 receptors.

There are also specific probiotic strains that degrade histamine. But be careful because some strains produce histamine. Here’s the list of strains.

Bifidobacterium infantis Bifidobacterium longum Lactobacillus gasseri Lactobacillus rhamnosus Lactobacillus plantarum Lactobacillus salivarius

There is also a low histamine diet to try. (Or high histamine foods to avoid)

Im going to try her on all four; diet, probiotics, DAO and antihistamines and see how she does.

Here is a graphic to check out how histamine causes so many symptoms
