Our body produces histamine naturally and it is also found in many plant and animal based products,such as; sauerkraut, dried fruit, yogurt, pork, aged meats like salami, aged cheese, alcohol; particularly red wine and canned foods. Breakdown of histamine in the body Histamine is naturally present in many plant and animal based products. In addition to the histamine produced by our body, it also enters the body through our diet. Excess histamine is broken down in the body. The digestive enzyme Diamine Oxidase (DAO) helps in the effective digestion of histamine (rendering it inactive) in the small intestine, preventing it from entering the bloodstream. DAO Plus capsules from Intoleran DAO Plus contains a special blend of the DAO enzyme and the antioxidants vitamin C and Quercetin, which help with the digestion of histamine.
