I have been reading lots of old threads and just stumbled upon this statement 'I know caffeine helps IP so I am taking a caffeine supplement', is this true?

I am not a coffee drinker, have gone off tea and ditched the Coke Zero so I am totally caffeine free. Should I be having some caffeine? All I drink is water (not flavoured in any way). Thanks!

That is not true in the sense it has no real efffect one way or another. You do have to limit coffee/caffeine to one cup per day. After that you need to switch to add an equal amount of water to coffee to counter the way caffeine can pull water out of the system.

Zero need to take caffeine as a supplement.

Thank you JLUS!
