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).
Although you get vitamins and minerals from the foods you eat every day, some foods have more vitamins and minerals than others. Vitamins fall into two categories: fat soluble and water soluble. The fat-soluble vitamins â A, D, E, and K â dissolve in fat and can be stored in your body. The water-soluble vitamins â C and the B-complex vitamins (such as vitamins B6, B12, niacin, riboflavin, and folate) â need to dissolve in water before your body can absorb them. Because of this, your body can't store these vitamins.
