HistaHarmony | Delayed Release DAO Diamine Oxidase Histamine Support Enzyme | 30,000 HDU | 60 Servings

This DAO enzyme works quite well to prevent histamine reactions from food. However, for me personally another brand (which I won't mention here) works even better. I suppose it depends on your level of histamine intolerance and how many HDU's (units) you require for a single dose. For many people, this supplement may be more than adequate. In my experience you don't want to take more DAO than is necessary because it can make you a bit lethargic (similar to the feeling of Benedryl). So, more or more powerful is not always better. I really like the packaging and individual sealed blister packs to prevent exposure to oxygen and the like. If you have problems with histamine intolerance (or think you do), give this one a try. If this supplement does nothing at all, then you probably don't have a lack of DAO enzyme. It's worth the money.

These pills come in a secure blister pack and are super tiny making them easy to take. I wish they were less pricey, but they work!

Excellent product. Easy to have with you. 30k HDU. Delayed release. Finally something that brings great support to the histamine challenges.

Made my symptoms worse and didn’t help. Taking just beef kidney capsules seems to work better for me.Many people seem to like this, so I think it’d worth a try. The company reached out to me to offer a refund. That says a lot about how they back their product and I appreciate it.

I tried several brands of DAO, and this one worked the best by far. Others worked for a few hours, then I would break out in rosacea papules anyway a couple of hours after eating. This time-released DAO lasts all day, even when I eat very healthy food that is full of histamines. The pills are very tiny, so easy to lose, but also easy to swallow.

Works as it states for better digestion.

Who would image that healthy foods like avocado, spinach, strawberries, kombucha, canned fish, etc. could have high levels of histamine in them? Certainly not me, until I read about histamine intolerance. The levels of histamine in these foods don't bother most people, but for people whose digestive system has been primed to react to histamine by chronic SIBO, MACS, or other digestive disorder, high histamine foods can cause a lot of bloating, discomfort, flushing, etc. Wait, what? Even some Lactobacilli produce histamine? No wonder I can't take probiotics or drink kombucha anymore!I'd recommend trying HistaHarmony to anyone who gets headaches from red wine, or feels bloated and ill after eating processed meat, cheese, avocado, tomatoes, spinach, or kimchi.Diamine oxidase (DAO) doesn't block histamine receptors the way antihistamines do (that's why antihistamines have so many side effects). Instead, DAO stays in your digestive tract, breaking down the histamine itself. A few years ago, there was only one company (Umbrellux) selling DAO. Nice that we have choices now! For me, HistaHarmony works as well as Umbrellux DAO, NaturDAO, and Histamine Digest, but at a lower price and without fillers. Don't be put off by the tiny pill vs. price - this isn't a case where size matters.Before DAO, I had gotten to the point that I was reacting to all foods, either nauseous, or crampy, or like my guts were going to explode. Two HistaHarmony before every meal (for me that's super fresh meats and veggies, low FODMAP, low histamine, no dairy, no grains, no yeast) lets me be OK after eating. Six HistaHarmony and I can have small amounts of say, red wine or sushi. This both a great relief and has let me feel like less of a food weirdo at social events. If you have food issues, give the Healthy Gut Company products a try. They are all good quality and backed by research.

I couldn't tell if it worked or not. Maybe a waste.
