I'm a pretty big "store brand is fine" guy but man, the kroger brand fiber supplement is dire. The only difference in ingredients from regular metamucil is that the kroger brand adds silica, and I guess that's why it just clumps up instead of just dissolving right and somehow manages to taste bad despite metamucil barely having what I would describe a taste to begin with. Sure it's five dollars cheaper but I will straight-up pay that five dollars over and over to never have to drink that stuff again.
