NAC and Yellow Urine

[bloodchoke]

Like all of us, I drink a LOT of water everyday. My urine is pretty much clear, even in the mornings (slightly tinted). For the last three days, my pee has been very definitely yellow. Not neon, multivitamin yellow, but yellow. I know that yellow urine is normal and I'm not concerned about anything; the sudden change is just weird. The only thing different in my activity, diet, etc., is that I started taking 600mg of NAC ed a week ago.

Is this common? Does NAC have a cumulative effect and am I just beginning to flush impurities from my poor abused liver?

EDIT: BTW, I'm not currently cycling.

I started NAC about a week ago myself and yes now that you mention it I think my urine is also more yellow than normal.
