Omne Diem DAO 30,000 HDU - 60 Caps - Histamine Neutralizing Enzyme - Relieve Histamine Intolerance with Diamine Oxidase - The Original Tested DAO Enzyme Supplement

I love this product. I had issues with histamine and was always in pain (bladder) and I found this magic pill. There were several foods I could not eat before I found this product. Tomato, cheese, watermelon, chocolate, vitamin C, lemons, etc. I am no doctor but I know it took the pain away. It took about a week of taking a couple of times a day for it to calm my issues. If I take too much, I see it drys my eyes. Now I take one a day and have no problems with histamine unless I have something with high-high histamine like bone broth. I have bought this many, many times and I will continue to buy it.

I use this product to keep my histamine levels in check. I appreciate the quality and purity of the product.

This has helped so much with my histamine intolerance. Lifesaver!

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!

These have worked Well For me

May 2024 -Disappointed by the quality of what I am receiving lately. (this product is unregulated so no real protection for us consumers). Do they even have quality control I wonder? I began using DAO in 2016 from the original co. (not this one) at 20000 units/cap and it worked GREAT - amazing in fact! Then a product shortage. DAO became unavailable, until this co. (OMNE DIEM ) started offering 20000 unit/caps , which worked OK. Eventually the original co (not Omne) started offering 10000 unit/cap product again, but not cheaper, so I began buying these, and they worked well enough. However, now - this co. (OMNE DIEM) has started labeling their product 30000 units (up from 20000 HDU) on the front of the label - on my last shipment, but their capsules are not working better as I would expect?? I have to take more capsules, not fewer, per meal, which really has me questioning how much effective DAO is really in these (OMNE DIEM's) capsules? Even with taking more it is almost like I am not taking much of anything. My diet has only improved over the years, fresher, with me getting better at avoiding high histamine foods. But it is not possible to avoid all histamine, and my symptoms are noticeable if I don't take enough DAO. It is obvious when I need to take more- which, again, I should NOT have to take more capsules per meal (like I am now doing) if there REALLY is more DAO in Omne DIEM's capsules ... as the new label SAYS. I will come back and update this review if anything changes. UPDATE: August 2024 - I am convinced there is false advertising or lack of quality control or something going on with this product from this company. Capsules are definitely not providing the DAO support I was used to getting for years, which makes these supposedly "30000 HDU" labeled capsules a waste of money.

Works well and I trust the testing.

I have this DAO on auto-ship, it’s the most effective product and brand that I have found to counter to histamine reactions from food which I developed as a result of living in mold for 4 years. I’ve used it for 3 years and could not eat without it. I highly recommend it!

Very disappointed that something this damaged could be sent to someone.
