I read the reviews on this stuff and it seemed too good to be true. I gave it to my very old dog with a compromised immune system who gets skin staph all the time. At first I noticed he breathed easier. Then I notice his staph drying up and his skin softening. His eyes look less cloudy and he seems to have less pain with his arthritis. I give him one pill a day and this seems enough for a 25 lb. dog. I am curious to see how it would work on a person now!
