Is Vitamin D the same as vitamin D3?

What is vitamin D3?

Vitamin D helps the body to maintain calcium levels, which is essential for healthy bones. It also maintains the phosphorus level in the human body. The fat -soluble vitamin D is also called "sunshine vitamin" because it is formed in the body when it is exposed to sunlight. Vitamin D is indispensable for the preservation of healthy bones, and its deficiency leads to the softening of the bone tissue, which leads to rachitis and adults to osteoporosis in children. The World Health Organization reports that osteoporosis is a big global health problem that is in second place according to cardiovascular problems. In view of the increasing use of sunscreen, minimal sunlight and the lack of sunlight in colder climate zones, it has become necessary to take dietary supplements in order to compensate for the daily requirement of vitamin D. These over -the -counter food supplements include vitamin D3 30000 IE and vitamin D3 50000 IE as well as vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is the natural and the most effective form of vitamin D. The term vitamin D is a kind of miscilization.
