Here is a list of vitamins that may help prevent and used as remedies to treat various conditions and disease that are caused by vitamin deficiency. Included are facts about vitamins, vitamin supplements, the benefits of vitamins and natural sources of each vitamin.
Vitamins are organic substances or compounds that are present in almost all foods and are essential for normal metabolism and other body functions. The body needs to get vitamins from foods because it cannot manufacture them.
There are about 13 types of vitamins of which vitamin B and vitamin C are water soluble while vitamins A, D, E and K are fat soluble. Water soluble vitamins are those that dissolve in water before they are transported through the body. Excess of water soluble vitamins are excreted and this is one of the reasons why you have to keep getting them in your diet. Fat soluble vitamins are absorbed by fat and stored in it.
Each vitamin has unique structure and specific functions but some of them work together to perform certain activities.
Vitamin A is necessary for healthy bones, lungs, skin, teeth, urinary tract and vision. Vitamin A is available as retinol and beta carotene or provitamin A in which it is converted into vitamin A in the body. It is also an antioxidant and it supports immune function. Vitamin A and vitamin B2 combined help improve and maintain mucous membranes in the digestive tract.
