Healthy Gut HistaHarmony | Delayed Release DAO Enzyme Supplement | 30,000 HDU Diamine Oxidase Histamine Blocker | 60 Servings

I prefer the DAO from Design for Health, but these are at a great price point and work very well. I have MCAS and take 2 at each meal which helps tremendously.

Fairly effective, especially when taking 2 tablets. I have major histamine sensitivity and I can even eat pizza (ultra-high histamine food) with zero issues if I take 2 of these at mealtime.

I love this brand. Has made a huge difference. I tried another brand, but it had extra ingredients that caused a bad reaction. The ingredients in this one are clean and I dont have the bad histamine reaction.

Hejpful with food intolerance.

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 had a lot of issues lately with food intolerance and foods with histamine. I had bought another brand and it was twice as expensive, plus it was a capsule. I hated having another pill to swallow. These are tiny. They're working and I'm not having the reactions that I was having.

Terrible reaction. Not sure why. I have histamine intolerance and this made me feel awful for 2 days. I seem to do better with beef kidney. Maybe porcine extract doesn't work for me. Just wanted to give a heads up.

The best DAO spent above the rest! Also, more for your money
