VitaMonk Histamine Blocker for Histamine Intolerance - HistaResist - DAO Enzyme Supplement Optimal Dose of Diamine Oxidase to Help Shield Histamine for Smooth Digestion - 60 Capsules

As someone with MCAS & histamine intolerance, this supplement has been incredibly helpful in reducing the food intolerance symptoms. I have been taking it for 16 months nonstop and it is a must have in my daily arsenal to manage some of my MCAS related symptoms.

I might work for some, but for me I got a bad reaction. I believe it is the ascorbic acid as my dr told me I cannot use this form of C. So disappointed after using only 2 pills I spent all that money to have to toss. I wish there was a return!!!!!! EDIT: I upgraded to a 5 star!! I cannot believe the company actually contacted me regarding my personal issue! I'm so impressed and grateful. When I have used up current probiotic by a different company, I plan to order the one from from this company VITAMONK.

due to my intolerance to fish in the scromboid family (tuna, mackerel, etc) that's not properly stored/handled, I need to take this when I want to safely eat sushi and not be encumbered. It works.

Seems to work

I felt like this brand was not as effective as others. The price is good. I gave this product a full bottle's try, taking two before each meal. My histamine issues are a recent development. I developed MCAS two months ago. The immunologist put me on H1/2 blockers twice a day and I hate the way antihistamines make me feel. I have 24/7 GI discomfort, but if I stop taking the antihistamines, I develop more systemic issues like angioedema, hives and anaphylaxis. I'm trying to find solutions to ween back the antihistamines and be able to eat as normal. The price on this is good, and it may work for someone with less severe issues. Customer service was very good as well.

Great Product

I tried this product but it did not work for me. I took for a few days and decided to go back to my previous product I used to reduce histamine. When I requested a refund they did not honor it and requested I take for 30- 60 days instead. They say they guarantee their product but don’t believe them.

This product is a life saver for anyone who suffers from chronic hives. I started breaking out in giant, red painful hives about 6 years ago. I went to several doctors before an allergist told me to take Zyrtec twice a day. I did that for years while trying to find a holistic solution for my problem. I tried food elimination diets, cryotherapy, gut healing detox’s and different supplements to try to ween myself off of Zyrtec and naturally heal myself. Finally, I stumbled upon an article about histamine intolerance and DAO. I researched and found Histaresist has simple and natural ingredients with outstanding reviews. I’m here to say this product works. I have been taking it for almost 3 weeks now and have not taken Zyrtec at all and have not experienced any hives. The longest I could go before feeling the itchy uncomfortable feeling of the hives surfacing was 2 days before I would have to pop another Zyrtec. For the first week I took a histaresist pill 3 times a day with meals. The second week just twice a day. This third week I am taking one a day and no hives or even the feeling that they are coming! I’m telling you, game changer!
