I've been dealing with on going gut issues on and off for the last few years. I've also in the last 18 month been struggling with "adult acne". Previously taking action with strong medication, which worked, but only for a period of time. I can't say my skin improved significantly, but I do definately feel that this product has improved my gut health. I am getting less bloating and flares of IBS symptoms after using PuraU intermediate program.
