Actually, taking it with something like orange juice would be a good idea.
Original research/rumours said that:
a) caffeine blocked it
b) you needed an insulin spike to absorb it (i.e. sugar)
c) acid stopped it working
d) that it almost immediately started breaking down when dissolved
Fact is you need to drink lots, and caffeine doesn't block it, insulin makes little difference, acid doesn't block it (your stomach is incredibly acid anyway!), and that it takes about 8+ hours to start to break down.
In fact there's some research that says taking it with sodium is a good idea (i.e. something salty). There's a fair amount of sodium in orange juice so it's a good choice.
You can also take it with a meal.
But it's well absorbed however you take it.
