NATURDAO - 1,000,000 HDU - DAO Enzyme Supplement - Histamine Block - Diamine Oxidase - Food Intolerance - 60 Tablets

UPDATE: Even though I could not take this product and it was not returnable, THE SELLER OFFERED A FULL REFUND. I HIGHLY RECOMMEND BUYING THE PRODUCT IF YOU HAVE NO ALLERGIES TO IT.I ordered late at night in need to get product to block an overload of histamine. It was my fault I overlooked it has microcrystalline cellulose which is usually from acacia. I am severely allergic to this plant/tree and have to beware of it in all meds and supplements. I hate it is non returnable when the protective film still in place.Had to trash it.

Why did you pick this product vs others?:I am on my 10th order of this product at least maybe more. Some days I have to use it every day with every meal, sometimes I don’t. I have histamine tolerance, definitely contributed by low DAO but also worsened with high Estrogen. It’s a life safer

Why did you pick this product vs others?:Been taking these about a month. Major improvement with hives. I would highly recommend

I've had rosacea for about six years. I've tried all kinds of creams, supplements, laser treatments, diet changes; nothing stopped the hot, painful facial flushing. After doing a ton more research and tracking my symptoms, I came to the conclusion that my rosacea is either caused or heavily influenced by a histamine intolerance or possible MCAS (which I suspect is caused by SIBO, but that's a whole nother beast). I was starting to flush after nearly every single meal, it was getting unbearable.I started experimenting, adding in several antihistamines a day along with this supplement. I slowly worked my way up to 1 entire pill since I was a bit scared of a bad reaction after reading some of the negative reviews. Luckily my body adapted fine. The first few times I took it, my chronically stuffy sinuses unclogged within literal minutes, it was weird but awesome (sadly didn't last!).More importantly, this supplement has made a HUGE decrease in my food-induced flare ups. Along with my regimen of antihistamines (h1 and h2 blockers) my after-meal flushing has become basically nonexistent, the change is almost unbelievable. Because I'm flushing less from meals, it means I'm flushing less all day long since my skin is staying calmer overall. Unfortunately it doesn't work on alcohol, I definitely still flush from that, but I had to test it lol.That leads me to the only drawback: the price. I've already gone through several boxes of these and it's only been a few months. I'm fortunate that I only need one pill for each meal and that I only eat twice a day, but man, I can't imagine if you needed several pills per meal and ate three full meals a day. And these are one of the cheapest DAO supplements on the market! Yikes. It's not sustainable, at least not for me, especially since I have a pretty large regimen of other supplements I need to pay for.I've considered 1. switching to eating one meal a day to save on costs, 2. going a strict anti-histamine diet to see if that decreases my need for the supplement, 3. growing my own pea sprouts (apparently they're high in DAO; who knew) 4. and/or cutting the pills in half to make them stretch further (you'll most likely need a pill cutter if you do this, these are HARD to cut with a knife).I even tried skipping them and just using my antihistamines only before meals to see if I could do without them but sadly, that didn't prevent a flush. As soon as I felt the flush coming on I quickly took one and my skin calmed down within minutes, so I know these are having a big impact all on their own.For now I plan to keep taking them despite my crying wallet, but I'm hoping I can get to the root cause of my histamine intolerance so that some day I no longer need them.

This product made me feel worse and I am still recovering. I took it for a week. Amazon said it was eligible for refund, then said it wasn't. Too bad it isn't, because I don't have money to waste, and it wasn't cheap. May help some, but made me worse.

Works well, worth the money.

Great product, it is strong at 1milliom HDU so I usually cut it into 1/4s and take with meals. Definitely recommended to anyone with histamine issues.

I have been happy with this product (works well for me, I take a 1/2 tablet) but last shipment arrived with the flap undone and tapped back with clear tape, which does not inspire trust. There is apparently no way (or no simple way) to return or get refund, which is pretty bad.My 3 stars are for the product efficiency, I took 2 off for this delivery issue. I am not sure I will take this batch.
