Note: Do not tilt your head back. This may cause blood to run down the back of your throat, and you may swallow it. Use your thumb and forefinger to firmly pinch the soft part of your nose shut. The nose consists of a hard, bony part and a softer part made of cartilage.
Vitamins are classified as either fat soluble (vitamins A, D, E and K) or water soluble (vitamins B and C). This difference between the two groups is very important. It determines how each vitamin acts within the body. The fat soluble vitamins are soluble in lipids (fats).
Of these, A, D, E, and K are the fat soluble vitamins. Vitamins C and B complex are water soluble vitamins. The fat soluble vitamins are commonly stored in special fat storage cells called lipocytes, whereas, the water soluble vitamins are not stored within the body except in small amounts.f these, A, D, E, and K are the fat soluble vitamins.
