My physician sold me the pure caps pure lean supplements for weight loss and they have helped tremendously. I like how pure encapsulation includes all of the ingrediants recommended for weight loss such as chromium all in one pill. Good thing is that it doesn't have caffeine in it. I also like that they included evidence for every single supplement. The only thing I don't like about the pure caps pills is the coating of the actual pill. It sticks to my throat when I swallow it. I also do not like how much more expensive the pills cost over generic CVS pills. Their website is an amazing wealth of anti aging and supplement information. I just wish I could buy their pills online rather than through my doctor.
