Omne Diem Histamine Digest DAO 30,000 HDU - 120 Caps - Histamine Neutralizing Enzyme - Relieve Histamine Intolerance with Diamine Oxidase

If histamine is your problem then these should help. I recently suspected I have a histamine intolerance. I can draw on my skin and I struggle with flushing especially after high histamine foods which are some of my favorite foods. After taking this supplement I have been able to keep the majority of my flushing at bay. And I turn reallly red after drinking alcohol, especially wine. I recently added high dose quercetin to my regimen and with that I was able to completely eliminate my flushing, even with drinking. I am so excited I figured this out and that I can socialize without turning bright red again! For reference I am taking 400mg of quercetin with it.

This is my favorite DAO product. I have tried other brands and I find this the most effective.I am so grateful to know about food histamine and how it effects me - I get a very dry, cotton mouth at night. So dry, it wakes me up. this product brings relief and allows me to eat a greater variety of foods.

I have a mast cell disorder with multiple food intolerances. This allows me to eat like a normal person within reason. DAO is the enyzme that we naturally secrete in our gut to breakdown histamine. One theory is that we mast cell folks do not secrete enough of it. This supplement is necessary for us.

I'm disappointed in Omne Diem.I've used about seven bottles of this product, and one bottle in January had an extremely strong plasticky petroleum smell. I tried to take them a few times and gagged severely, so much so that I actually vomited.I decided to reach out to Omne Diem, the manufacturer, for their advice.When I emailed them, they admitted there was a manufacturing defect with a certain batch of products released on the market. They explained:"It seems a few bottles at the end of a 5,000-bottle production batch were affected by the heat seal staying on too long which caused an odor to develop inside the bottle. Please return the product to us for a free replacement."This explains why the pills tasted strongly of plastics, almost like petroleum. Because the pills were infused with heated plastics. But I understand these things happen and I didn't get angry; I decided to just take them up on their offer.They got back to me later saying they couldn't find my order number. I explained, again, that I purchased on Amazon, and I had already provided them with the receipt PDF.It was at this point that they completely ghosted me. They stopped responding to my emails. I reached out several more times giving them an opportunity to correct the situation, and they never answered any of my messages after that point.So, know that you might be potentially buying a product that is not subject to sufficient quality control... which might produced by a company that just might completely ignore you if you are affected by such an issue.I wish you better luck than I had.

I use this product for histamine management, and have been very satisfied.

Update: I am updating this review to 4 stars, because my confidence in the quality control is now shaken. I depend on this stuff and if a bad bottle comes that means I am without and have my symptoms for several days until I can get a replacement. But I might consider ordering this brand again because I did finally receive a refund for the bottle I describe below, and the capsules have always worked great, and come at a very competitive price.original review: I have purchased this supplement 5 times. I found it worked just as well as much more expensive brands (eg. xymogen). However, in the last bottle I received, the capsules have a very strong odor like the smell of a candle when you burn it out. There must have been some kind of problem in the manufacturing process to produce this powerful of an odor. I can't imagine that burnt wax smell could be created by anything that I want to put inside my body. I can only conclude that there is no good quality control. Furthermore, I have tried contacting the seller to no response, and there appears to be no way to contact the manufacturer apart from the "distributor" (Omne Diem) address on the bottle.So unfortunately, I will never order this again as I really can't risk opening another unreturnable bottle of defective, likely toxic capsules. This is to say nothing of having to live without this enzyme I apparently lack and benefit so much from all the while I have to sort this out. What a drag!

I've been using this product for over a year. It helps my histamine intolerance. Highly recommend

This product works. DAO has helped to feel better and be able to eat more foods.
