It gets into the urine very quickly, it should be completely out in 12-18 hours.
If your urine is any color but yellow i would suggest consulting your family physician. However, having clear urine is completely normal and is actually the most healthy color urine to have. There is really not a vitamin to turn your urine a specific color.
That is the color yellow, which may simply be due to the yellow dye used in vitamin B tablets.
Urine is usually yellowish. Vitamin B2, (riboflavin) makes it a bit more yellow.
The bright yellow color which appears in urine within a few hours of ingesting Vitamin B is simply the excess of the vitamin being excreted from the body. Most supplements contain much more than the body needs and it is excreted, coloring the urine yellow.
The normal yellowish-amber color of urine is mainly due to a chemical called urochrome or urobilin, which is produced from the breakdown of heme. Vitamin D itself is white and, as far as I can find, doesn't have a particularly notable effect on urine color. Some vitamins can affect urine color... B vitamins, for example, can produce a vibrant, almost fluorescent yellow or green color, and vitamins A and C can turn urine orangish. If you're concerned about drug testing, using foreign substances to impart a "normal" color to diluted urine will only fool a cursory visual inspection (if that... the B-vitamin yellow looks, to the trained eye, "odd" compared to the normal color produced by urobilin).
Both cyanocobalamin (a form of vitamin B12) and vitamin B2 can cause bright yellow urine.
Answer Are you taking vitamins? A common reason is from multivitamins. Vitamin A & Vitamin B tends to make your urine a highlighter yellow. I have just researched that drinking too many energy drinks that contain B Vitamins can do this too.
B vitamin supplements
The bright yellow color of urine after taking a multivitamin is harmless. It is caused by the excretion of excess vitamin B12. The water soluble vitamins are excreted through the urine when more is consumed than the body can use.
Yellow
What color is your urine use crack
You need to drink more water. Aim (no irony intended) for a pale straw colour in your urine. Bright yellow is too undiluted and needs dilution by drinking more, Taking vitamin B supplements will also cause urine to be a bright yellow color - so if that is the case, no worries...
