Monavie has a patented process that harvests the acai berry in a way that preserves all of it's nutrition.  It is hugely different from any other product out there.  Many people I know have tried other products and ALWAYS come back to Monavie.  It is now the official drink of the Boston Red Sox.  Ask them if they would ever drink anything else.  Plus there is zero added sugar and it is non filtered juice.  This stuff is Amazing!  That's why the Doctors had it on there show!
