i have histamine and numerous food sensitivities. This product has supported me in two very important ways. First, I am slowly adding foods into my diet that are healthy and not high in histamine, but I just couldn't tolerate it. My digestive system feels balanced. I am adding the foods slowly, but it is working. Second, and almost equally as important, I am having a healthy response in my skin when I add in the new foods. For example, previously, between my digestive system and skin sensitivities, I just couldn't tolerate any oatmeal. I'm now able to eat almost a serving of oatmeal several times a week. I just cannot say how much this product has helped me. It is definitely worth a try.
