The best company I have come across by far is Advocare. Everything they produce is made by actual doctors and pharmacists so they are completely safe. They have a lot of different products, so not all of them are for weight loss. My husband just finished playing college football and he has lost about 25 pounds of his football weight so far. I'm down about 9 so far. We liked it so much that we actually started distributing ourselves

.
I would highly suggest looking at MNS (Metabolic Nutrition System) for overall health and weight management, and possibly trying some Spark. Spark is an energy drink made completely of Vitamins with zero sugar. Both phenomenal products. If you have any questions feel free to ask!
