Hard to tell with a supplement...
because they are usually not something you are taking by themselves.  That said, since I've been taking these (as well as some Keto Salts and a Hydration pill) on a daily basis, I haven't been experiencing the same kind of hunger pangs as I have in the past.  It's possible that this is just a side effect of being on a Keto diet, but they deserve the benefit of the doubt, as the days before I started taking them (when I was just into Ketosis) were miserable.<br /><br />They are cylindrical shaped capsules, that are clear, so you can actually see the clear fluid inside them.  They are fairly fragile, and are packed with cotton, which brings up the only issue I've seen so far -- when my bottle arrive, one had broken open (and was stuck to the cotton), leaving the entire contents just slightly slick.<br /><br />Would I buy them again?  Sure; you take four at a shot, and they seem to help with the cravings that I otherwise experience in the mornings.
