The original formula of Solo Slim and Solo Slim Extra Strength were recalled back in Sept 2010 because they contained an ingredient that was similar to a prescription drug used to suppress appetite. They were voluntary recalled and can be returned to the place of purchase for a refund. Now in the end of Oct, 2010, Ezville, the manufacture of Solo Slim has released their new updated formula under the brand name of Solo Slim Advanced. They claim that this is a better formula than the original was. One difference we did noticed is that there are now 60 capsules in a bottle instead of 30 and you take 2 capsules daily. You can purchase Solo Slim Advanced from this website.
