| Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. Vitamin D obtained from sun exposure, food, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D [25(OH)D], also known as calcidiol. The second occurs primarily in the kidney and forms the physiologically active 1,25-dihydroxyvitamin D [1,25(OH)2D], also known as calcitriol. | |

| Vitamin D is essential in bone growth. Its main role in the body is to increase the flow of calcium into the bloodstream. It does this by promoting absorption of calcium from food. Without vitamin D, calcium would not be absorbed into the body. Therefore, vitamin D is equally important to the maintenance of bone health as is calcium. Vitamin D has other roles in the body. It is used in the maintenance of several organ systems as well as the immune system. Because of its important functions, vitamin D deficiency can lead to many other health problems. Heart disease, arthritis, diabetes, high blood pressure, and even cancer have been associated with a lack of vitamin D. Additionally, new studies suggest that vitamin D may play a role in protecting against Alzheimer's and Parkinson's disease.

| Vitamin D is one of the most important vitamins for our overall health, but many people in the United States, as well as worldwide, are not getting enough of this vitamin. And the only way to know if you're getting enough of this vitamin is by doing an expensive test. And everyday it seems, new studies show new reasons why this vitamin is so important to our health. Although vitamin D can be stored in your body fat until it is needed, the problem is that it's not so easy to get enough vitamin D into your body. The main job of vitamin D is to keep the right amount of calcium and phosphorus in your blood?these are the 2 nutrients that work together to make your bones strong. If you don't have vitamin D in your body, only a small amount of the calcium from your diet can be absorbed by your body, and only a little more than half of phosphorus is absorbed. Without enough calcium and phosphorus being absorbed in your body, your bones would become brittle and break easily. Until recently, experts believed that the main role of vitamin D was to keep our bones healthy and prevent them from breaking up.

| Vitamin D is a steroid vitamin, a group of fat-soluble prohormones, which encourages the absorption and metabolism of calcium and phosphorous. People who are exposed to normal quantities of sunlight do not need vitamin D supplements because sunlight promotes sufficient vitamin D synthesis in the skin. Vitamin D for humans is obtained from sun exposure, food and supplements. It is biologically inert and has to undergo two hydroxylation reactions to become active in the body. The active form of vitamin D in the body is called Calcitriol . What do we need vitamin D for? It is crucial for the absorption and metabolism of calcium and phosphorous, which have various functions, especially the maintenance of healthy bones. It is an immune system regulator. It may be an important way to arm the immune system against disorders like the common cold, say scientists from the University of Colorado Denver School of Medicine, Massachusetts General Hospital and Children's Hospital Boston. | |

| Vitamin D is a fat soluble vitamin that plays a vital role in the human body. It has many functions, and a lack of vitamin D can lead to many health problems. Vitamin D has other roles in the body. It is used in the maintenance of several organ systems as well as the immune system. Because of its important funstions, vitamin D deficiency can lead to many other health problems. Heart disease, arthritis, diabetes, high blood pressure, and even cancer have been associated with a lack of vitamin D. Additionally, new studies suggest that vitamin D may play a role in protecting against Alzheimer's and Parkinson's disease. Pregnant women, at greater risk of malnutrition, should closely monitor their vitamin D intake. It has been shown that those with low levels have given birth to children with low bone density. Vitamin D is naturally produced in the human body when exposed to sunlight. Limited sun exposure has been a leading cause of vitamin D deficiency. Depending on season, geographic latitude and time of day, you can receive an adequate amount of vitamin D simply by goin outside. On average, 10 to 15 minutes of sunlight will provide you with a daily amount of vitamin D.

| Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone and to prevent hypocalcemic tetany. It is also needed for bone growth and bone remodeling by osteoblasts and osteoclasts [1,2]. Without sufficient vitamin D, bones can become thin, brittle, or misshapen. Vitamin D sufficiency prevents rickets in children and osteomalacia in adults [1]. Together with calcium, vitamin D also helps protect older adults from osteoporosis.

| the importance of vitamin D is highly underrated. It's not only good for bone health, but has also been correlated to improving a host of illnesses, including colon cancer, inflammation, multiple sclerosis, seasonal disorders and depression. Although you can take vitamin D as an oral supplement, the best way for it to be absorbed is by getting some sun exposure. "Everybody is afraid of the sun—everyone uses hats and sunscreen to cover up everything, and we don't really get out in the sun," Because of this, people are getting less vitamin D, he says. While doesn't recommend spending a long time bathing in the sun, 15 minutes a day will get you the vitamin D levels that are recommended. Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone and to prevent hypocalcemic tetany. It is also needed for bone growth and bone remodeling by osteoblasts and osteoclasts. Without sufficient vitamin D, bones can become thin, brittle, or misshapen.

| Humans attain vitamin D from exposure to sunlight, diet and supplements. Vitamin D deficiency is common in children and adults. In utero and childhood, vitamin D deficiency may cause growth retardation, skeletal deformities and increase risk of hip fractures later in life. In adults, vitamin D deficiency may precipitate or exacerbate osteopenia, osteoporosis, muscle weakness, fractures, common cancers, autoimmune diseases, infectious diseases and cardiovascular diseases.
