XYMOGEN HistDAO - DAO Enzyme Supplement to Supports Healthy Degradation of Food-Derived Histamine - Diamine Oxidase for Digestive Health 20,000 HDU Per Serving (60 Tablets)

Really happy with the quality and price. They are very tiny pills in a blisterpack. I just cut a section out of the blisterpack to keep in my wallet so I can use them as-needed when I'm not home. I have to take these almost daily and they're a life-saver for me. When my lips swell due to increased gut histamine, these take care of it. (I have never had a full anaphylactic reaction, so I am not recommending these for that, which would require medical attention). But I am saying that these help manage my histamines so I can enjoy more foods. I usually take these right before or during eating a meal that has caused my lips to slightly swell. I have no other obvious symptoms of high histamines.I also take a daily antihistamine on top of taking these as-needed.

I started having a histamine reaction from food and took a half of a pill. In 15-20 minutes my reaction stopped! Without this pill my reaction would go on for four miserable hours. I did not have any negative side effects from this pill. I am so thankful for this product and appreciate that it is made from natural ingredients.

Very effective histamine blocker

This was a game changer for stomach. I can finally eat things that would send me into a tail spin. It is easy to swallow, fast acting land small enough you don’t have to worry about tasting it lol

Works as described. Arrived on time. 3 stars as would prefer if the lightweight paper box were sealed in an outer package or envelope - weird to receive medication in the mail with no layer of protection. Too easy to tamper with. Box arrived smashed. Luckily the pills were ok.

Great SellerArrived just as described, on time, great conditionwill shop with this seller again

Seems to work even better than the prior brand I tried. Small pill. Easy to take.

WOW! I had to ove to a carnivore diet to remain alive. My gastrointestinal system is so compromised, almost all food is untenable. What I can eat, and certain rotations, are histamine release at risky levels yet a other risk to my ability to function. Medical AI c was me up with THIS PRODUCT: AI was right....8 Specialists and over a half-million in diagnostics could t figure this out and would not have with another million. This is a miracle for me.
