Answer:
Dear
Heinrich,
It does
indicate that you are probably consuming more vitamin B2 than your
body can utilize at one time.
"Yellow"
is just excess unabsorbed vitamins.
When
your urine changes color its letting you know that the vitamin has
fully dissolved in you body.
Taking
some vitamins will turn your urine intensely yellow.
The 'bright
yellow' color in your urine after taking a multivitamin comes from
the water soluble B vitamins.
Vitamin
B complex greatly influences the urine color.
Ribloflavin,
or vitamin B-2,and B-12 are especially guilty of causing bright yellow
urine.
Dark
yellow urine is caused by dehydration.
