Neurobiologix Gut Histamine Supplement, NAC & Quercetin, 60 Capsules | Digestion & Immune Balance, Vitamin C & Bromelain, Food-Derived Response, Vegetarian

This product has been a lifesaver for me! It was recommended to me by my nutritionist (RD) and by the GIMap for histamine intolerance. I take it just before I eat a meal that might be high histamine and it prevents the very uncomfortable symptoms that can come when I eat histamine rich foods, such as fish, leftovers and tomato based meals. It's great - I love this product, it's been a massive benefit to me.

It’s an important supplement for my digestive system

the old formula was great. there is something wrong with this new one. had a rash after taking this and stomach did bother me a few hours later. might be the n-acetyl cysteine. and for some reason quercetin isn't listed as an ingredient anymore on the new bottle. why fix what isn't broken?

This was a great supplement, and then they “enhanced” the formula with no warning, adding an ingredient that my body doesn’t tolerate with NO warning. I actually depended on these and I’m struggling to find something else before I run out of my old bottle. Some warning would have been great so I could stock up.

I've been struggling with histamine issues for a few years and this has helped tremendously. I started with one a day but then realized it's best to take it with every meal so take it three times a day now.

These yellow capsules are the standard supplement size, easy to swallow, and have almost no smell or taste. They say these are meant for histamine reactions, and they warn you are not meant for allergic (anaphylaxis) reactions to food. Quercetin, vitamin C, stinging nettle, bromelain, and alpha lipoic acid, are all natural histamine blockers of different types. And the porcine kidney is to give you extra DAO, which is the main enzyme that breaks down histamine in food. The doses of the individual items are quite small relative to what you'd take if you had each component individually, but hopefully by taking all of them together you need less of any one. The instructions say to take them before eating histamine-containing or triggering foods, which makes me think you don't need to take regularly for them to work. The cost is high so I justify it by thinking it's not something I need to take every day like vitamins, rather a preventative for when I want to splurge on food. What I wouldn't do to have a tomato! Or an avocado! If this works as they suggest, it will be SO worth it. Anyway, I've decided to start slowly and be very measured about reintroducing histamine foods, so this is only the initial review upon arrival. I'm giving 4 stars to account for the cost and will raise or lower the stars after I get to experiment with them over the holidays. They came with 2.5 yrs left on expiration. They're GMP manufactured and gluten, dairy, and soy free. But they are not third-party tested.

I have quite a number of foods I have sensitivity reactions to. Not full on allergic reaction as that means epi- pen & ambulance, but definitely stomach issues, sometimes hives, &/or itching. So, decided to give these a try. Used them as directed, then drank 8 oz cow's milk (one of my sensitivities is dairy). I had no stomach cramps or lower intestinal issues. Instead, the milk went down, stayed down, & gave me no issues at all. Super impressed with these pills!! Going to give them a try with some other food issues tomorrow & see how it goes. Sure hope they keep working. Will LOVE being able to handle cheese again -- even if its only once in awhile. Plant-based "cheese" is just gross! Tomorrow's menu -- grilled cheese & tomato soup (both issues in the past!) I'll keep posting as I discover more help or any issues!

Does exactly as it states in the description. Ive had absolutely no side effects with this supplement. They’re easy to swallow, and doesn’t have a bad aftertaste!
