Designs for HealthHistaGest-DAO - Diamine Oxidase DAO Enzyme to Support Digestion of Histamine-Containing Foods - 20,000 HDU DAO Diamine Oxidase Enzymes (60 Gastro-Resistant Tablets)

A bit expensive, BUT they work really well and are high quality. Also the dispenser packaging is PERFECT for keeping in a purse or bag. I like that it dispenses one into your hand without having to open an entire bottle.

This product works very well

This enzyme is a game changer if you have a histamine intolerance. I take one before I eat at all restaurants, because they all seem to serve something I can’t eat and it’s usually an ingredient I can see. I don’t take anymore risks, I pop one of these in my mouth and it stops any possible reaction I would suffer due to my histamine intolerance.

My rating is arbitrary--I tried these pills as part of my extensive search for remedies to my teen's allergies to avoid the usual crap. They didn't help but that is because the allergies were not related to diet intake.This product may be good for those specifically needing it.

Works great for my son.

These tiny pills seem to make a difference in my skin and digestive system after I eat particularly high histamine foods. I have been taking two before meals.The only thing I was not happy with was the package was taped closed with a type of perforated tape and that was the only thing that sealed the product. Once I opened the outer box (that had the not very secure tape), the actual dispenser didn't have anything protecting it from being used. It needs to be better protected so that you know it hasn't been tampered with before it gets to you.

Great. Love the dispenser too. I took one star off for being expensive, especially when you rely on taking 2-3 of these per day to get by.

Works well for Mast cell issues
