With creatine for bodybuilding, why is it recommended not to be mixed in an acidic Juice before cons

I have creatine powder for bodybuilding, and it says on the package to mix with a non acidic juice. So I cannot mix it with orange juice. I was wondering what the reason for this was, and would mixing creatine powder with orange juice decrease it's efficacy.

Very simply it negates the positive effects due to it's acidity

Best though is after training to consume in water with a couple of teaspoons of sugar.

Or add it to your protein shake.

If you are in the loading cycle, just consume the powder at intervals throughout the day with water and sugar mix.
