From the vitamins

A

B_{1}

B_{6}

B_{12}

C

D

E

and

K

, the number vitamins that can be stored in our body is ____.

Answer: 5

Solution

Fat-soluble vitamins (A, D, E, K) dissolve in lipids and are stored in the liver and adipose tissue, since they are not readily excreted in urine. Most water-soluble vitamins, including

B_{1}

and

B_{6}

and C, are not stored and must be replenished regularly through diet.

B_{12}

is the one water-soluble exception — it is stored in the liver in appreciable quantities for years.

Vitamins that can be stored in the body: A, D, E, K and

B_{12}

— 5 vitamins.
