I'm not sure if you can buy Intestamine in stores. It's produced by Douglas Laboratories and you may need to buy it online somewhere. Just do a google search. I was checking out that Intestinew stuff and it seems pretty good. The only difference from Intestamine is that it has a little less glucoasmine per serving. But it has the same amount of L-Glutamine as Intestamine and is a little cheaper. Also, it is made by ReNew Life and I know that Whole Foods carries a lot of their products, so if you can't buy Intestamine online, you might just try to get Intestinew from a place like Whole Foods. The quality of ReNew Life stuff is pretty legit. I used their Candizyme product and it worked pretty well (at least as a digestive enzyme; not too sure if it worked on the candida).
