Normal urine color ranges from pale yellow to deep amber — the result of a pigment called urochrome. But urine color isn't always normal.

B vitamins turn urine an eye-popping neon yellow, for instance. Carrot juice can tint it orange. And porphyria, a disease that affects your skin and nervous system, earned its reputation — and its name — by turning urine the color of port wine.

Most changes in urine color are harmless and temporary — the result of certain foods, dyes, supplements or prescription drugs. Occasionally, though, unusual urine color can indicate an infection or serious illness. Talk to your doctor about changes in urine color that persist or don't seem linked to medications or food.

hi, just a question but it seems you all are talking about vatimin B, would high intake of any other vitamins cause this effect too or is it just vit B?

In general it is the B-complex vitamins.

My boyfriend and I take a b vitamin and the same thing happens. my boyfriend looked it up and I guess you could say bright urine is just a side effect nothing to worry about.

It's always been my experience that anyone who brags about how high their IQ is, is not that intelligent to begin with. Why do you have a need to advertise this information on a forum?

Or it is possible you have a high IQ and have the need to belittle others that may not be in the top 2%. Give me a break, grow up!

Must be nice. So does Mensa accept people regardless of whether they are self absorbed and love to belittle others? Maybe they should apply an ethics standard requirement of all Mensa members. Too bad they accept people only based on IQ. There's so much more that goes into making a healthy, well educated and well rounded individual.

On the urine note. Flushing out excess vitamins does not mean that it was not absorbed. Since B-vitamins are water soluble, they must pass through the digestive tract in order to be eliminated. Through these processes, the body uses what it needs, and eliminates the rest. Try putting a black light bulb in your bathroom. It might be more fun than magazines.
