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)

Very effective histamine blocker

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

I ordered another (cheaper) brand that not only didn’t work but made me extremely nauseous. I like the size of these tablets (easy to swallow) and the amount provided (60). These not only prevented my usual reactions to histamine-rich foods but allowed me to be a little less restricted with my diet. I have found my go-to brand.

Works great 👍

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.

It helps.

When I have this enzyme before a meal I notice that my stomach is noticeably flatter as I am digesting the food. Also, I'm digesting my food better as noted by the output. I have had intestinal surgery and I have no colon so my guts have impaired enzyme production. I have been trying all kinds of enzymes for different foods and this one definitely helps with tomato and pineapple!

I’m in tears. For years anytime I eat out at a restaurant I get sick, a headache and so lethargic I basically go home and collapse into a nap, or feel like crap the rest of the day. For the first time in as long as I can remember I can eat food again without feeling like death. It took so long to figure out what the problem was and it turns out it was just this simple issue with my bodies reaction to histamine.
