Not to say that a vitamin won't help, but when I was running a ton sometimes I got them from dehydration. The piss color test is real easy to do; if you wake up in the morning and your first piss looks the same color as apple juice you need to drink more water before bed. If it's clear or slightly yellow you're doing just fine. The darked your piss is the further behind you are on water. Some vitamins also turn piss a neon color, but that's something different.
