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.
