How long is Creatine stable in solution?
Creatine is not totally stable in solution, so it’s definitely not a good idea to keep it mixed with liquid for days, but there shouldn’t be a problem mixing it six to eight hours before it’s consumed. Any longer than that and you may be pushing it. Creatine monohydrate is unstable in a liquid form. In order for the supplement to be stable it has to pass through many stabilization steps which can only be created by educated scientists in a laboratory environment who are familiar with the detailed patented process required to perform this conversion.
