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

This product helps me eat like a "normal" person. It is the enzyme that you naturally produce that breaks down histamine in your digestive system. One theory is that people with mast cells issues don't make enough of it. This is the absolutely necessary supplement for food intolerances. It does not work for people who have true IGE allergies to food. Wanted to make that clear.

Seems to work well. Haven’t used it long enough to be sure. I try to really limit the histamine foods I eat, so it’s hard to say if I’m getting better at that or if it’s the supplement. But it really DOES seem to make me feel better. And I do know for certain it prevented a histamine reaction from one meal.So, I do recommend trying it. I’m now certain I do have histamine sensitivity.

I have been taking this product for a little over thirty days and I have been able to tell a big difference..

I have Mast Cell Activation Syndrome. I had read some reviews that this product helped other patients with my disease. MCAS is more than *just* food allergies, so this DAO vitamin won't help with chemical and environmental allergies due to MCAS, but it does however help to some extent with my food allergies.I will say that it is good to take this around 15-30 minutes before eating. I am less reactive to foods that I am normally more reactive to, when I take these pills. People with MCAS usually have a DAO deficiency, which is why this vitamin is so helpful. Just one pill alone is usually not enough. I read some reviews on MCAS website about this product and they suggested taking anywhere from 2-5 pills before each meal depending on severity of the histamine content in the food. 2 or 3 pills is what I usually do and thats what seems to work best for me personally. I have already bought a second bottle because it works so well. It is expensive but WORTH the price for histamine intolerance.

Don’t work, and caused severe stomach pain and cramps unlike a few other DAO brands I’ve tried for histamine intolerance

Between high histamine levels and immune disease I must carefully select supplements with full review of active and inactive ingredients prior to purchase. I react to all nightshades, legumes, citrus, nuts and much more. For 10 years I would often wake in the morning to a very swollen face, hands and gut with nasty malaise and great exhaustion!?!?I learned from a Mast Cell Specialist about the high histamine gut and eliminating high histamine foods. With IBS that lead to SBO (that I can't take antibiotics or probiotics for due to reactions) that wiped out one of the two enzymes in the gut that blocks histamine you end up with swelling. The mystery was it usually hit overnight while sleeping or within 10 minutes of waking???? Histamine rises at night and first thing in the morning!! Bingo after 10 years of hiding half the day due to swelling and feeling terrible I finally have it under control because of this supplement. Every now and again I will wake to a swollen face but the incidence of this happening has dropped 95% since it started taking this supplement twice a day when I eat. It has made a remarkable difference in my quality of life and have taken it every day for 4 months. i plan to stay on it for years to come. it really works for me and I hope it works for you, but like many supplements you need to find what works best for you and your system. I like the product very much, its not full of extra stuff I don't want or need and it works great.

These are great to use before drinking. Less hangover, less headaches, less stomach ache, stops flushing from wine or other things I can sometimes be sensitive to… love these.

I eat an insanely low histamine diet but still have reactions. This lets me branch out a little bit more! Only tried for 3 days, but it made a huge difference.
