DAO Enzyme - Histamine Blocker Supplements with Diamine Oxidase & Vitamin C for Daily Histamine Metabolism & Immune Support - 60 ct

I have a laboratory conformed case of DAO deficiency resulting in histamine related symptoms. Rashes, Hives, Abdominal Dysfunction and other symptoms. I used a pure DAO supplement without successful results. I use the European food list of histamine producing and high histamine content foods. I also added a probiotic regimen. All my symptoms have disappeared and I am not running to the toilet all day long. This product is more effective and affordable than the last one I tried. The ingredients appear not to affect me. Each case presents individually and is relatively newly recognized disorder and is difficult to find a specialist in histamine disorders. So be patient and know yourself. Update , this product is still working for me. I developed another condition that has been challenging to overcome. I don’t think it works for the new condition but while I’m recovering I continue to use it daily. I still watch what I put in my mouth but I don’t blame this product on the new condition since the new condition has been equated more with the aging process. But overall this product has been a lifesaver for me. I still think it’s important for anyone to receive a proper diagnosis and treatment from a specialist. This type of product was just coming out about the time I received my diagnosis. I used a couple of different products and this has helped me the most.

This histamine blocker works fast and helps me enjoy foods without the usual issues. I like that it’s just one capsule, made with clean, plant-based ingredients, and easy to take before meals. Simple, convenient, and definitely part of my routine now.

I’ve been using this Histamine Blocker for about a week and so far I really like it. I take it before meals and feel more comfortable afterward, especially with foods that usually bother me. Easy to take, gentle, and fits well into my routine. I’ll definitely keep using it.

Not a cure-all for eczema sufferers but does tone down skin reactions from food. Bought because I know my eczema is triggered by histamine. Wasn't positive whether it was helping at first but then when I went without the tablets for a couple days and got more itchy during meals I knew it was effective.

This supplement has been a helpful addition to my routine. I notice I handle high-histamine foods with a bit less discomfort than before. The capsules are easy to take, and I haven’t experienced any issues with them. While everyone’s body is different, I’m glad I gave these a try as part of my daily support for histamine sensitivity.

I’ve been using this to help with histamine intolerance, especially around meals, and it has made a noticeable difference for me. Easy to take, gentle on my stomach, and I feel much better when I use it consistently. I’m happy with this purchase.

I like how convenient this supplement is — just one capsule before eating. It’s especially helpful when dining out or traveling, when you don’t always know what ingredients are used. I also appreciate that it includes Vitamin C and is gluten-free and non-GMO.

I have severe chronic illness and unfortunately spent money on this brand thinking it would work like the other brand I have gotten, but it did nothing .. I am so disappointed and sad cause I spent money I could have used for Lyme treatment or for food. The other DAO enzyme i took has less DAO enzyme on the label, yet this one is as if there is none in it at all. When I bought it it said I could return it which is why I was comfortable trying it, but now it saying "not eligible for returns"! I got it 3 weeks ago! I wish I could return it as I am not employed and this was a vital part of my recovery I took it with several meals and each time, it did nothing. I also got the one with the rice in it which is not the one I ordered. I was fine with that aspect. each time it didn't work, I gave it the benefit of the doubt that maybe there was some other variable but because the results were repeatable so many times it's undoubtably the supplement that is not working. I will have to email them and see if they will take it back cause I have $2 in my bank account. I can't afford to throw $35 away. I need to treat my chronic conditions 😪😣😢
