My vitamin levels remain the same on each, but the SourceCF is much more palatable. The other has a bad smell, and I burp it for 2 hours, even if I take it before a heavy meal. I don't have that problem with SourceCF. Even though I get the SourceCF free through the Creon program, they sent me the AquAdek instead. Maybe they thought they were doing me a favor by sending the name brand, but I was disappointed.
