What are some dietary supplements that actually give good results?

I have lost a total of pounds but it has been a long and arduous task. I think I should have lost more for the amount of time I have been trying. I know I need to control my eating more and I am trying to get back into my eating better, 100%, but I wanted to get a supplement to help with the process. Any suggestions. && Dont respond if you want to tell me to do it the natural way. Thank you.
