Consider the following:
1. Vitamin A
2. Vitamin B (Complex)
3. Vitamin C
4. Vitamin D
5. Vitamin E
6. Vitamin K
Which among the above is / are fat soluble vitamins?

Answer: [B] 1 , 4, 5 & 6

Vitamins are divided into two groups: water-soluble (B-complex vitamins and C vitamins) and fat-soluble vitamins (A, D, E and K). Unlike water-soluble vitamins that need regular replacement in the body, fat-soluble vitamins are stored in the liver and fatty tissues, and are eliminated much more slowly than water soluble vitamins. The fat-soluble vitamins, A, D, E, and K, are stored in the body for long periods of time and generally pose a greater risk for toxicity when consumed in excess than water-soluble vitamins. Eating a normal, well-balanced diet will not lead to toxicity in otherwise healthy individuals.  However, taking vitamin supplements that contain megadoses of vitamins A, D, E and K may lead to toxicity. The body only needs small amounts of any vitamin.
