Can stick in your throat
Beware – may be hard to swallow! It just arrived and I immediately wanted to try it. The pills are small, true enough, but they’re “thick” for lack of a better word. They’re also a bit rough and grainy.This one stuck in my throat – wouldn’t go up, wouldn’t go down. I could still breathe, thank heaven, but to have it stuck in your throat was bad. For one thing, my body kept manufacturing saliva until choking on the excess saliva soon became the primary problem.I’m going to keep using them but I’ll have to cut them and/or smash them into a powder and put the powder into a drink or food. I’ll update this later as to the effectiveness. Right now, I need to warn anybody out there that if you have any trouble swallowing pills, cut or smash these down first!UPDATE: these pills have no taste, thank goodness, so they can be smashed and put into any kind of food or drink. I have a “pill smasher”; first you cut the pill into sections (get a pill cutter at the drug store), then smash the pieces into powder. Then put the powder into peanut butter for instance, or a hot drink where it will dissolve further. So far, I’ve only gotten one down, so I’ll write later as to the effectiveness.

Made me very, very sick
Tried using these but have had nothing but bad experiences. First time, a bit of a stomach ache as soon as it hit. Second time, again, but it passed. Next few times, I always felt some stomach discomfort and pain, but thought I just needed to stick to it so my body could adjust. Then there was today. Got the initial stomach ache, but thought it would be OK. Ate dinner and felt fine. However, immediately after eating I began getting a stomach ache, and it kept getting worse. I got the sweats, felt weak and possibly the worst stomach ache I’ve ever had. It lasted over an hour at that level, excruciating pain, and then came massive vomiting and equal problems from the other end. I’m no stranger to gastric issues of various kinds, but I was seriously concerned. I won’t be taking this again.

Stopped my Endless Runny Nose
I was having an issue with a non-stop runny nose and overall congestion for weeks on end. Antihistamines barely made a difference, if at all. I uploaded my 23&Me data to an online site that will analyze and provide reports and one mentioned something about the DAO enzyme in my case likely to be deficient. (Sorry, I’m not a super technical/science expert).In any event, I took one of these before each meal in the beginning and this made a difference very quickly for me. No more runny nose! I’ve since backed off but will take these if I notice the runny nose creeping up again.Everyone’s different. Your experience may vary. I also purchased a lower dose DAO from this same manufacturer but haven’t tried those. I just seem to have very high histamine (mass allergies, runny nose, neverending rash, et cetera) so this is part of the solution I’ve found.

Keep heart rate normal after a meal
It’s great at preventing drowsiness after a meal. I take it 15-20 minutes before a meal on an empty stomach and sometimes even if I had a snack. I take it before a hearty, full of carbs meal. I have tried a different brand of DAO enzyme with less enzyme per capsule and it barely made a difference for me. So don’t hesitate just because it’s MAX, it’s probably exactly what you need.

Super helpful if you are on a limited diet
I started taking this from a suggestion on Reddit in swallowing disorders. I had been struggling with achalasia and had already had a poem procedure. I was having a lot of reflux and having to eliminate more and more foods. This product really helped and I have been able to decrease my indigestion meds and add foods back into my diet. It doesn’t solve everything but it made my life much better.

Great product, economical option
This stuff is great, it helps so much with histamine intolerance issues. I like the economy of the smaller lower potency pills, I tended to break the stronger ones in half anyways as I typically don’t need a full one, if I’m consuming a super high histamine meal I can always take 2 of these. No issues with stomach or the fact they are derived from legumes.

The best DAO supplement for histamine intolerance hands down.
So happy with this new format. Much better value for money, easy to dose (1 for snack, 2 for a meal, 3 for high histamine content). Work very well for me! Thank you!!
