Review: Be consistent, have a firm diagnosis from a qualified doctor and be patient, - 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.
Review: Great 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.

## Questions & Answers

**Q: What are the capsules made of?**
A: I don’t know but it’s really unsettling that there isn’t an ingredient list on the bottle. Is it even legal to sell supplements in the US without an ingredient list? The capsules are bright yellow so it’s not “just a vegetarian capsule”. There’s clearly a dye involved. Even if these work, I’m not sure I can justify buying them again without knowing what I’m putting into my body.

**Q: Who makes this product? From which country does it come?**
A: Our Bravado Labs products are manufactured in the USA.

**Q: What is the dao in this supplement derived from? other answers here, one says pork and the other says vegetables and fruit. which is it?**
A: Our Histamine Block is consist of fruits and vegetable extract that are rich in diamine oxidase, which makes our product vegan-friendly.

**Q: Is this vegan? is says dao is pork?**
A: Most DAO is derived from pork.

### ⭐⭐⭐⭐ It's helping reduce my hives
*by M***M on August 23, 2026*

I'm almost finished with my first bottle and it seems to be helping. I'm not getting hives nearly as often or as bad. I do have a few minor complaints/concerns, though. It comes with no instructions at all, so I read all of it's reviews (there were hundreds of them!) and found only three that mentioned WHEN to take it. One said they take a pill 10 minutes before eating, one said 15 minutes and one said 30 minutes. I decided to try 15 minutes, which works fine when I remember to take it. Unfortunately brain fog is another symptom when you're prone to hives, but hopefully it will become part of my routine soon. Also, the bottle when new is very difficult to get open. You have to remove the shrink wrap the prevents the cap from unscrewing first, then once you get that open there is a seal across the opening that has to be peeled off. Another thing you might want to know is that it's a capsule, so you can't cut it in half. One reviewer mentioned breaking it open to spread the powder inside it over their food, presumably to remove the need to wait for the capsule to dissolve in your stomach before eating, but I have no idea how they manage to get the capsule open. And keep in mind that hives can be from other things besides food or beverages. Taking an enzyme will not help with contact allergies such as latex. My last complaint is that when I ordered more a couple of days ago, I chose to get two bottles at a time since they're less expensive that way, but Amazon only delivered one bottle.
