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

Hands down the best and most effecitve DAO supplement for me. There is a significant and positive difference to other products that I have tried. However, it is also a very pricey supplement so find the one that works best for you.

Thanks to this supplement, I can eat whatever I want now. Previously I was on a low histamine diet, only eating certain foods & using a pork based DAO (blech). Then I decided to make the swap to this vegan version because it's so much stronger with the 1,000,000 HDU & only needs 5 minutes to start working! It took about a week or two for me to stabilize my histamine levels with this enzyme. And now? This weekend I ate hibachi, miso soup, pizza, pickles & ranch. No problem. Never have experienced any side effects, either. Highly, highly recommend if you're dealing with histamine intolerance. Seriously a game changer!

NatruDAO is amazing! I've been feeling so tired and I have two other autoimmune conditions that I couldn't seem to get under control no matter what I did with diet, exercise, medications, supplements. Someone suggested that I may have a histamine intolerance so I read up on it and realized I have all the symptoms so I went looking for a DAO Supplement and although this product only had 56 reviews at the time I purchased it, every review had 5-stars. I read through the reviews since I'm skeptical when something has an abundance of 5-stars reviews but they all seemed to be from real people, so I ordered this product two weeks ago.It comes in a box of 60 tablets and you take one tablet 5 minutes before you have a meal, so you will probably use 2-4 a day depending on your eating habits. Some people have said they break the tablets in half so they get more value for their money. I haven't tried that yet.While this product may seem a bit on the pricey side, it is WELL worth the money. I noticed a huge difference the first day I took it. I started feeling less fatigued and had more motivation within the first 24 hours. After two weeks, I've noticed I'm not as bloated. I sleep better. My skin isn't as dry. My joints have been hurting less. My bowel function is almost back to normal. I brain feels less dizzy and my memory function that was starting to wane is improved. I've gotten more done around the house in the past two weeks than I have in the past four months because I haven't worked all day and then just felt like I needed a nap or that I was in too much pain to do anything. My spouse has commented that I have been in a much better mood and much less irritable.I haven't tried any other DAO supplements, so I don't know if any are comparable, but after using this product with such stellar results, I don't think I would change products unless another one had effects that were just as good but at a lower price.They also suggest eating a low histamine diet for additional support. I haven't gotten that far yet and have been eating regular foods, some high in histamine. I do plan to try low histamine foods as a means to feel even better, but this product seems to work well even when you're eating high histamine foods. Some high histamine foods I've eaten in the past two weeks while using this product include tomato sauce, shrimp, chocolate, egg whites, green peppers, pizza, cake made with wheat flour, ham, sausage, several oranges and orange juice.I know that my review makes this seem like a "miracle supplement" but if you have histamine intolerance, it really is.Now that I have my histamine in check for now, I'll see if the half tablets work and report back after I've had time to fully assess.

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.

I’m sure this works for some people but it’s definitely not for me. My allergist wanted me to try it to help lower my histamine level since it breaks down histamine in food. I took one pill one time and I will never take it again. It gave me the worst stomach cramps, bloating, gas, and nausea that I’ve had in a long time. No amount of stomach meds could touch it. I took it at supper and felt sick the rest of the night and the next morning. Unfortunately you can’t return the item so I’m out almost $40 for one pill. I’m very sensitive to things so like I said it may work for others but if you’re sensitive like me, beware.

Delivered promptly after order. Still evaluating efficacy.

Exceptional customer service. They reached out to me and gave me a full refund. Very generous as it was my error. I have a histamine allergy to beans so this didn't agree with me.
