I've heard a lot about raspberry ketones. Some are great and some aren't. Which are the best ones to take?
There are now a lot of different types of them. I already tried a couple but those didn't work well. I do would like to lose some weight. But I just don't know which raspberry ketones to take to achieve my goal. So, which ones are the best ones to take? I would like to lose at least 30 to 40 pounds.
