Review: Hard to tell, but I think it’s helpful - I think this DAO has been supportive.

Everyone's body responds differently. With an inflamitory diet, the benefits might be minimal. But if your already avoiding the foods that make ur immune system mad, this product does s pretty good job of reducing histamine levels that can drive u mad. **Q: does this product have pork or porcine as an ingredient?** A: It contains "Diamine Oxidase (from porcine kidney protein concentrate) 20,000 HDU". The label also states "60 Vegetarian Capsules". "Does not contain: Wheat, gluten, corn protein, yeast, soy, dairy products, fish, shellfish, peanuts, tree nuts, egg, artificial colors, artificial sweeteners, or preservatives." **Q: Hi, how can you say your caspules are vegetarian if the contents are made out of pig's kidney?** A: Technically it does not contain pork. It contains an enzyme found in pig kidneys. I wouldn't call that pork. There are no allergy causing proteins from pigs in the capsule. It should be a safe product for anyone with pork allergies. On a religious basis I don't have an answer. **Q: Why does this product contain so many toxic fillers (shellac(!), polyvinylpolpyrrolidone, titanium dioxide)?** A: The titanium dioxide appears to be a mistake on the safety info above. The actual product label from the maker's website does not list titanium dioxide. http://www.seekinghealth.com/histamine-block-seeking-health.html ## Customer Reviews ### ⭐ Check when you first receive…. *by B***. on 12 August 2023* Received in April. I used other product first, decided to give it a try today but the item was already open despite having a seal on the outside. I am not sure if the product has been tampered with and I’m concerned about purchasing anything else from this brand again. ### ⭐⭐⭐⭐ Hard to tell, but I think it’s helpful *by S***T on 25 July 2026* I think this DAO has been supportive. I’m not flaring after eating so perhaps it’s because I am taking one 10 min before the meal. ### ⭐ Ironically, had a bad histamine reaction *by P***Y on 23 September 2019* I'm mean, it's not really a surprise given the fillers. Why shellac? I'm probably the most sensitive person alive due to a long standing chronic illness that has gradually brought my body to a place where I'm overwhelmed with histamine on a daily basis. I can only eat three foods and have been looking for answers for years. I finally figured out on my own (because docs seem clueless) that I have histamine intolerance and the reactions I have to foods fall exactly in line with having an over abundance of it. You can imagine how excited I was to try this product! I might actually get my life back. Nope. I started the way I always do with new supplements and opened the capsule to try only one of those tiny little beads you find inside. Five minutes later I'm reacting quite noticeably having all of my hallmark indications of a histamine reaction. Queasiness, itchiness, swelling sensation in throat among the most noticeable. Good thing I didn't take a whole pill. Since I know I've never been allergic to pork and the bottle says you don't even absorb the DAO in the first place I figure it must be a reaction to one of the fillers. The only ones I feel like I'm new to are the shallac crospovidone and carboxymethylcellulose. Seriously people, you want to help the ones who most desperately need this product and you use all this extra crap? I contacted Seeking Health customer service before I tried this product after reading the negative reviews to try and get some answers as to what might be causing the bad reactions and, of course, they could give me nothing but the generic "everyone reacts differently". Don't bother trying to get any real answers or speculation out of them or even a direction to follow where to find answers. So anyways, obviously I decided to take a chance with bad results. I even tried to break open one of the tiny balls to see if it would reveal the contents are separate and encapsulated in hopes that I could painstakingly weed out the actual DAO itself but it looks like it's all melted together...just in case anyone is as desperate as me to find a way to make it work XD. Unfortunately, I can only wait for a product to come out without all of the dangerous fillers as I've already whittled my diet down to three foods so the anti histamine diet is out for me. Seeking Health, don't bother to request I contact your customer service for help. I've done that and you didn't have a whole lot to offer so please just leave me alone until (or IF) you decide to figure out a way to offer us desperate people DAO without all extras our bodies can't handle. Thanks guys. Have a great day. Have fun eating whatever you want and enjoying life while I eat my Teff bread for the millionth time in my life and waste away in my bed. EDIT: For anyone who's interested. I've learned that you can essentially make your own DAO by growing pea sprouts and consuming them fresh and raw approx. after 10 days of germination. It's not hard to find out how to do this yourself online. I'm resorting to this. Feel free to ask for an update on this if you're curious. Today is 9/25/19 and my first batch won't be ready for a couple of weeks. UPDATE: For anyone who cares... I tested out a small amount of pea sprout and had the same reaction to it as I did this supplement SO, the only thing I can conclude is that it has something to do with my body's reaction to DAO itself. I can't think of a reason for why something that's supposed to lower histamine actually has the opposite reaction in my body. Symptoms were noticeable in my ease of breathing, throat swelling, nausea, dizziness and face tingling/itching. I did read a study on how the Catalase enzyme is supposed to help break down the byproducts of when histamine is broken down but since my reaction was so quick after hitting my stomach with both the peas and this supplement I'm not sure it has anything to do with a low level of Catalase in my body or anything like that. If I learn anything new I'll post it! ## Frequently Bought Together - Seeking Health Histamine Digest - Formerly Histamine Block, DAO Enzyme Supplement for Histamine Food Intolerance, Supports Digestive Health, Upset Stomach, Vegetarian (30 Capsules)* - Seeking Health ProBiota HistaminX, 10 Billion CFU Low-Histamine Probiotic Supplement for Gut Health, Microbiome Balance, Digestive Comfort for Histamine Intolerance, Vegan & Vegetarian (60 Capsules) - Pure Encapsulations Magnesium (Glycinate) - Supplement to Support Stress Relief, Sleep, Heart Health, Nerves, Muscles, and Metabolism* - with Magnesium Glycinate - 90 Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/723624706-histamine-block-provides-20-000-hdu-of-diamine-oxidase-ascorbic](https://www.desertcart.jp/products/723624706-histamine-block-provides-20-000-hdu-of-diamine-oxidase-ascorbic) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-29*
