This product seems to work well in increasing metabolism and weight loss. I lost 5 lbs the first 2 weeks, and did nothing different. I feel warm, so looks like it works well. The problem I have is with the label. It does not clearly explain what's in it. I had to send 3 emails to the manufacturer / distributor before I got a response. I asked for a third party report verifying what's in the product. The label just says it contains 800 mg of pure coffee extract. What does that mean???? I asked, took 3 emails and got an answer that it contains a significant amount of chlorogenic acid (the active ingredient). Why do they not specifically put this on the label? Anyway, it's a good product and I recommend it, but it would be a big step forward in putting this information on the label.
