Hi,

recently I have had some need to drink lots of water.

Since I also take all the vitamin b-complex through beer yeast, I worry that all the b vitamins will be gone.(by following the water i've "digested").

If we say I take my b-vitamins at 8 o'clock morning and then drink lots of water, later I go to toilet at 9 o clock and 9:45 o clock, do you think the b-vitamins have left my body, or at least about 95% of them have left it?

[the two times I visited the toilet means that the water I drink leaves my body.]
