Vitamin D consists of secosteroids that are soluble in fat. Cholecalciferol is Vitamin D3 and ergocalciferol is Vitamin D2. These two are the most relevant, physiologically speaking, in this group of vitamins. Once the sun comes into contact with the skin, Vitamin D is produced. Whilst there is also Vitamin D in foods, there is still a prevalence of vitamin d deficiency, a topic which is highly publicized both online and offline.

Vitamin D is transported to the liver through the blood stream. Once Vitamin D reaches the liver it is converted into cacidiol. Cacidiol promotes the growth of bones and other things and is a pro hormone. When people have too little Vitamin D their bones will become brittle and thin. Young children who are Vitamin D deficient may develop Rickets disease. In adults the disease which results is osteomalacia. Most Americans do not have sufficient levels of vitamin D and it is essential that one obtains all the information needed to combat this deficiency.

Older people who take Vitamin D may be better able to resist osteoporosis. Vitamin D reduces inflammation and causes modulation of the neuromuscular function.

Symptoms of a deficiency may not be evident or they may be mild. Weight loss, tingling or weakness of the muscles, cramps, a stooped posture and bone pain may be some of the symptoms. Those with pale skin are more prone to have insufficient levels of Vitamin D.

There are a number of more serious diseases that can manifest as a result of low levels of Vitamin D. These diseases include depression, cancer, heart disease, multiple sclerosis, arthritis, adult onset diabetes and high blood pressure.

Rather prevent these illnesses than have to get them cured. One way in which you can do this, is to get enough exposure to the sun, particularly the shorter ultraviolet B rays of the sun.

It is not necessary to live in the sun 24/7. One third of an hour per day is sufficient for light-skinned people. The more tanned you are the longer you will need to be in the sun. Late afternoon and early morning sun is best as this is when the sun is not at its hottest. Eating foods that are fortified with Vitamin D will also go a long way in preventing vitamin d deficiency.
