It's not necessarily a danger sign. You may be simply offloading
a high concentration of vitamin C (which, when you over-consume,
simply dumps the excess to the urine), or betacarotene, the
precursor to vitamin A, and the coloring agent in lots of orange
fruits and veggies such as carrots or cantaloupe. Also, a lot of
the B-vitamins can have this exact effect. If the urine is clear,
this is a good sign and makes the vitamin density the most likely
It could also mean that you're somewhat dehydrated and you're
expelling very rich urine. In that case - rehydrate! :} Note that
this works better with liquids that have some electrolytes in them
- some salts. These include sports drinks like Gatorade, various
juices (such as orange, pineapple or tomato), or simply drinking
water and having a banana or two (high in potassium - an
Far less common are cases of kidney problems. But if this is a
new phenomenon for you, and has no other symptoms, I wouldn't worry
unless it persists.
I would definitely rather be excreting excess vitamins in my
bright yellow (normal) urine, than having clear urine and
vitamin-starved body cells.

Asparagus is another veggie that will make your urine bright
yellow. Drink lots of water (8 glasses a day) and that will help to
flush out the kidneys.
Bright yellow urine can mean that your body is dehydrated and
also it can mean you are highly acidic. Yellow urine indicates that
a person is able to flush out acids stored in the body or that a
person's body is not able to process the food that he is eating. If
it is the first situation it is good. If it is second situation it
is bad. Liver does not get any water if taken with meals or shortly
afterward. Such water is flushed out of the body faster. One should
drink 1 hour before meals to be able to get the water to the liver.
Except for this period one should not drink water. Drinking one
hours before meals will help water to stay in the body for a longer
period and work on the acids and toxins for a longer time.
Taking certain vitamins will turn your urine intensely
Urine should be almost clear in color, if you're drinking
enough clear fluids. The less you drink, the darker your urine will
become, and some medications will affect urine color. If you're not
taking meds, then up your water intake; drinking cranberry juice
also helps the kidneys to flush any toxins which can lead to
urinary tract infections.
Water, water and more water! Six 8 oz. glasses a day is what is
good for you, but even 4-5 will make a difference.
To add, it is usually the B Vitamins, found either in
multivitamins or as a additional supplement, that can make urine
bright yellow or even orange. Other medications, such as ones for
urinary tract infections, can do the same thing (such as
phenazopydidine, AZO-standard, etc.). Read the information the
pharmacy gives along with any prescription medication you are
taking to see if this is a common side effect of them. Otherwise,
you can certainly see a physician if you are concerned.
Although this is a commonly mentioned "fact" in the news, there
is no scientific evidence behind the "8 glasses of water a day"
Before you spend a bunch of money on supplements (many of which
are useless), try drinking more water. Urine is yellow because the
major waste product of the blood, bilirubin converts to urobilin in
the kidneys. Urobilins are yellow. Drinking more water will dilute
your urine and it will appear clearer.
While it is true that many are re-thinking the "8 glasses a day
theory," it is also true that not being properly hydrated can cause
urine that is bright yellow in color. B Vitamins and other
medications can also cause discolored urine. Pay attention to your
fluid intake (and remember to drink before you feel thirsty), and
you should see a change in color.
