Which of the following vitamins is generally excreted by human in urine?
-
- Vitamin B
- Vitamin C
- Vitamin D
- Vitamin E
- None of these
- Vitamin B
Correct Option: E
More than one option is correct. All of the water-soluble vitamins such as Vitamin C and B vitamins (Thiamin, Riboflavin, Niacin, Pyridoxine, Cyanocobalamin and Pantothenic acid) are generally excreted by the human body through urine if they are in excess. These vitamins are absorbed by the digestive tract into the blood stream, metabolized and then excreted by the kidneys in the urine. Distinctly yellow urine may indicate excessive riboflavin (Vitamin B2) intake.
