Which among the following pairs of Vitamins is stored in our body relatively for longer duration?
  1. (A)Thiamine and Vitamin A
  2. (B)Ascorbic acid and Vitamin D
  3. (C)Thiamine and Ascorbic acid
  4. (D)Vitamin A and Vitamin D✓ Correct

Answer: (D)

Solution

Vitamins A, D, E and K dissolve in fat, so the body can hold them in the liver and in adipose tissue and draw on that reserve over weeks or months.
The B group and vitamin C dissolve in water, pass into the blood and are excreted in urine as fast as they are supplied, which is why thiamine and ascorbic acid have to be taken regularly.
The pair stored in the body for a relatively long duration is vitamin A and vitamin D.
