Isagenix

The Isagenix Total Health and Wellness sytem and 9 day cleanse has been amazing for me.  I shed fat, built muscle mass, slept better, had way more energy and lost unhealthy cravings - so could stick to any other diet intentions more easily.  The science behind cleansing is new, but all I know is that about 9 out of 10 people I meet who try this system stick with it because they feel the difference. 
 
Here's a good source of detailed reports on this system by bodybuilders and fitness pros who love it: click here
 
The supplement watch review of this system needs some updating because the company has since that time published scientific studies that have backed their claims with data.
