Question

Which vitamin is excreted out in high quantity through urine in man?

• A. Vitamin C
• B. Vitamin B
• C. Vitamin E
• D. Vitamin K

Answer 1

The correct option is A Vitamin C

The water-soluble properties of vitamin C lead to urinary excretion of the vitamin. Metabolites of vitamin C including dehydroascorbate (DHAA), oxalic acid, 2-O-methyl ascorbate, and 2-ketoascorbitol are also excreted from the body via the urinary system. The kidneys play a major role in vitamin C excretion and retention. DHAA can be reabsorbed by the kidney tubules.
