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.
