Tonalin CLA - What is it? Does it work?

Options
So I was at the drugstore the other day buying vitamins and saw something called Tonalin CLA in the "herbal remedies" section that caught my eye. The label on the bottle said that it helps with losing body fat and toning. I find it hard to believe that there's something you can take to help your body with "toning". Has anyone tried this supplement before and had any results (good or bad)?
