I just finished up a bottle of diet pills, like I've shared here before, and they had a hoodia supplement in them.
I couldn't take them all the time, because of my silly stomach issues, so I didn't experience a consistent result.
So I am not a good case study, but you can find out all about hoodia side effects at the Hoodia Gordonii Guide. There are 69 people's stories there.
They were actually on Oprah and 60 Minutes, that's cool. I would love to try a product like that - the pills I was on had a ton of ingredients in them - kind of like a chemistry experiment going into my mouth! The pills recommended on this site seem so much more natural!
