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

This is a great daily supplement for the stomach. Price is not bad, sleeping better than I expected.No taste and they are working great.

Great Product. Does what advertised.

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’ve used other DAO enzymes, particularly by seeking health, and have had zero issues, just histamine relief. My tried and true was sold out, so I decided to give this a shot after promising reviews; but this actually made me feel worse. I’ve tried it on an empty stomach, and 20 minutes before consuming histamine rich foods, as suggested, and I developed allergy-like symptoms, as well as brain fog. It just made me feel off. I even gave it a week, playing around with the timing, and it’s been the same story. Maybe this works for some but, for me, it’s a purchase that I regret and wish I could get my money back on.

Great product with great ingredients

It has taken me years to figure out that I have a histamine intolerance and these are the only enzymes that really help me. I love that they are so small and I usually only need to take 2 a day with an extra before a high histamine meal. A lot of other supplements require 6 capsules daily. Highly recommend!

These are great. I recently found out I have a DAO enzyme deficiency and supplementing with these has made all the difference. I feel better. I did not get an upset stomach like some other people reported. The pills are tiny. They are well packaged.

It works!!!this is the best dao supplement out there, good quality
