This product has helped tremendously, so I don’t react as much to my food intolerances.

I have rosacea. Several years ago I noticed that my skin was getting very dry and flaky. Also my fingertips were getting so dry, that in the winter they would crack and bleed. Another issue I had was waking up in the middle of the night with a terribly dry mouth: I had a hard time getting saliva started at night. I was so thirsty during the day I would drink 10+ glasses a water every day, and still felt thirsty. It was like I had eaten cotton. I read a review on line about a rosacea product, and the reviewer mentioned that maybe his dry skin was related to food histamine. That review sent me researching all about food histamine and brought me to this product. It took several months to clean up my eating habits and get that excess histamine out of my system. Apparently our bodies are suppose to make a digestive enzyme called DAO, that helps to break down food histamine so our bodies can tolerate it. As we age or take certain medications, some bodies stop making enough DAO. This product helps to supplement that need. Its expensive. but worth it. I can now get by on just taking just one pill 2-3 times a week, and all my dry skin and thirst issues stay under control. But, if I miss a week or more, they start to come back. So I know this product works.

I got this because I have a non IGE mediated soy allergy and MCAS. I take it when I am at a restaurant and suspect I might have some soy. I definitely notice a difference as far as if I take this versus if I don’t. As far as histamine goes, fighting release helps a little bit with whatever you’ve got. What I notice most is a slightly less scratchy throat, better GI tolerance, and a *little* less bloat. I like it enough that I have bought quite a few bottles and believe it’s worth a try.

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!

Worked like a charm. These capsules are medium size and easy to swallow. Can also be opened and the enzyme sprinkled on food or and drink. This product has really helped me managed my histamine load while balancing my micro biome.
