Vitamins are organic substances that can be found in plants and animals and they are vital for the body to function normally. Vitamins are essential to our health and they can be obtained from foods. Each vitamin is important and has different task to perform. There are six known vitamins and they can be divided into two groups: water-soluble, which include vitamin B and vitamin C and fat-soluble, which include A, D, E and K. Vitamin D, like other vitamins, can be found in plant and animal sources although there are not many food that contain it naturally. However, many foods found in stores are fortified with synthetic vitamin D such as milk and dairy products.
Vitamin D can be absorbed by exposure to the sun since our skin can convert ultraviolet rays into this vitamin. But vitamin D also has to be obtained from foods because modern lifestyle involves spending most of the time inside, and because certain climates don’t provide much ultraviolet rays. Vitamin D can also be taken from vitamin supplements.
