Vitamin B-2 (riboflavin) is the one.  It can in heavy doses turn the 
urine almost an orange.  When taken in excess you excrete what your 
body does not use.  It is also a clear sign that your money is going 
down the toilet <grin>.  RDA is 1.7 mg.  Check out your Multi-vitamin 
and see how much B-2 is going down the toilet <grin>.  17 mg is 1,000% 
of RDA and I have seen some as high as 100 mg in some preparations.  
It seems to be harmless .....but expensive.

I decided to answer this question publicly rather than e-mail because it 
is my opinion that this question and answer would be better served is 
the groups below rather than here.
