Hi yvonne. I moved your post to our Nutrition and Supplements forum. Up at the top you'll find a sticky with some useful links to supplement information - both supplementwatch.com and wholehealthmd.com have write ups about CLA. I have been taking CLA (in conjunction with green tea extract) since May 1st and I've noticed a rise in my metabolism. CLA and GT in combination seem to make for one huge anti oxidant punch - another great benefit.

If you scroll down this forum a little ways you'll also find some interesting info on Green tea and zinc.
