Do you know what is Hoodia? It is an extract that comes from a cactus in Southern Africa and a good appetite suppressant. So, hoodia diet pills is said to be effective and no side effects. But other notions shows that hoodia is not effective and not safe to use as well. That confuses everyone if Hoodia really works. Hence, the way how Hoodia works is it suppresses you appetite by tricking your brain into thinking that you are full. This diet pills was popular back then. I even heard this name before in every commercials on TV and even on the web. Don't try anything if you are uncertain of its effectiveness or better yet read the reviews for better understanding of the products.
