It has become clear this disease effects people differently which is why it is so difficult to find a one size fits all plan for recovery. Adding to this, what works one month may not work the next bc your symptoms change very quickly. What I can say about this product is before I started taking my current regimen of medications and supplements, I could not eat 99% of the things I attempt to digest. It has been like this for almost a decade. I started taking this supplement and Cromolyn, and now I can eat about 80% of the things I want. Yes. I cried. Alot. How do I know it is because of this supplement and this supplement alone? I think at this point it would be foolish for any of us to think after years of suffering, it is only going to take one little pill to make us normal. IDT we will ever know what normal is ever again. I can say that I am confident that this supplement is a part of a regimen that works for me that has enabled me to eat pizza at night with my wife as we watch Game of Thrones (she hasn't seen it yet - so no spoilers! :) I ran out this week and with it being Christmas week, I got behind on re-ordering so I haven't taken it this week and I have thrown up my dinner twice sooooo using that data, one can extrapolate that with the supplement I am able to keep pizza down. Without it, I vomit. Needless to say, I am re-upping. I did not have any side effects taking this supplement daily for a month. All I felt was a increase in health benefits ranging from increased food choice to less exhaustion. Review: Works great for histamine triggers in food - This is a great product and works much better than other DAO supplements I have tried. Also it is less expensive. I have many histamine food allergies and have been dealing with this for awhile. I found there was no taste to the pill and was easy to swallow I also like that I can take the pill right before I eat a problematic food and don’t have to do so in a specific time frame. The company is a small business and customer service has been very helpful with a quick response. I’m very happy with the product and would highly recommend it. ## Features - DAO Enzyme Supplements Histamine Blocker: Formulated to support digestion of histamine-rich foods, promoting comfort and overall digestive wellness - Concentrated Diamine Oxidase (DAO) enzyme developed to complement the body’s natural digestion of dietary histamines, helping maintain digestive harmony - Specifically formulated for histamine sensitive individuals: Intended for those sensitive to dietary histamine, offering digestive support and comfort following meals - Advanced Enzymatic Formula: Provides targeted support for digestive health and general gastrointestinal comfort through DAO enzyme supplementation - Convenient 30-count histamine digest supply ensures consistent daily supplementation.

Can you show that DAO is viable when exposed to stomach acid?** A: All I know is that my terrible allergies subsided much quicker than with with antihistamines. I don't know how I can show that the DAO is viable in stomach acid otherwise. This might be a really good question for the company though. ## Customer Reviews ### ⭐⭐⭐⭐⭐ If you have MCAS and are searching for a DIO supplement, then give this a try *by M***R on January 4, 2023* If you are like me, you are taking a multitude of medications and supplements to treat your MCAS/POTS/Dysautonomia/ETC.
