Vitamin D plays an important role in health

It seems like almost every day a new use for an old vitamin surfaces. Vitamin D is in the group known as fat-soluble vitamins. It comes in two major forms. There is vitamin D-2 or (ergocalciferol) and vitamin D-3 (cholecalciferol).

The vitamin D obtained from sun exposure has to undergo change before it can be an active vitamin D. The active form of vitamin D is the vitamin D-3.

Vitamin D plays an important role in many organ systems. It is important for the absorption of calcium and phosphorus from food. It also is important in re-absorption of calcium from the kidneys. Vitamin D is important for the health of the body's skeletal system.

Vitamin D also is important in the body's hormonal system and it is very important in preventing multisystem diseases which include such chronic conditions as high blood pressure, infections, periodontal disease, chronic pain, memory loss, maybe even in diabetes and certain cancers.

Vitamin D can be obtained in certain foods such as cod liver oil, fatty fish, whole eggs, beef, liver and mushrooms. Certain food products are fortified with vitamin D. An example of this is dairy products.

The amount of vitamin D a person needs is being investigated on a regular basis. At one time, it was thought that as little as 2000 units a day was adequate. Now, there is thought that a higher amount might be indicated.

It is a good idea to see your family physician to determine what vitamin D level you currently have. The standard for deficiency has been changing as well. Many authorities believe the optimal level of vitamin D in a person should be between 30 and 100 nanograms per milliliter.
Because vitamin D is fat soluble, it can, in excess, lead to toxicity. A person should not take vitamin D tablets without talking it over with a doctor.

A lot of research is being conducted today about vitamin D's role in a person's health. There is reason to believe that vitamin D deficiency can actually lead to the body's immune system not being able to function properly. Research today is suggesting that vitamin D may play a role in causing cancer cells to die. A study by the National Cancer Institute recently has found that vitamin D was beneficial in preventing colo-rectal cancer.

Also, there is reason to believe that vitamin D may play a role in preventing prostate, pancreatic and breast cancer. There is no question that vitamin D deficiency plays a significant role in osteoporosis. Vitamin D deficiency has been shown to be associated with increase in blood pressure and cardiovascular risk. One study suggests that all caused mortality is higher in people that have low serum vitamin D levels. Other studies have suggested that vitamin D deficiency has some role in dementia.

It is a good idea for a person to eat a good and balanced diet. It is equally important for a person to have a good examination by a doctor.
