What is Vitamin D
Vitamin D: A steroid vitamin which promotes the intestinal absorption and metabolism of calcium and phosphorus.
Why Do I need it
Most natural sources of vitamin D are animal-based, including fish and fish oils, egg yolks, cheese, fortified milk and beef liver. Known as the sunshine vitamin, vitamin D is produced by the body in response to sunlight. You may be at risk for deficency if you are homebound, live in northern latitudes, are a strict vegetarian, wear long robes or head coverings for religious reasons, or have an occupation that prevents sun exposure. If you have dark skin, the pigment melanin reduces the skin's ability to make vitamin D in response to sunlight exposure. Some studies show that older adults with darker skin are at high risk of vitamin D deficiency. Sunscreen, a must for preventing wrinkles and, of course cancer reduces your skin's ability to make vitamin D by 90 to 99 percent, depending on the level of SPF thoroughness of application. As people age their kidneys are less able to convert vitamin D to its active form, thus increasing their risk of vitamin D deficiency. Certain medical problems, including Crohn's disease, cystic fibrosis, and celiac disease, can affect your
intestine's ability to absorb vitamin D from the food you eat. If you are obese vitamin D is extracted from the body by fat cells, altering its release into the
circulation. People with a body mass index of 30 or greater often have low blood levels of vitamin D. Receptors in the brain need vitamin D to keep hunger and
cravings in check, as well as to pump up levels of mood-elevating chemical serotonin. Every cell in your body needs D to funcion properly--including fat cells. Special receptors for D signal whether you should burn fat or simply store it; when D plugs into these receptors, it's like a key that revs your body's fat-melting mechanism.
A 2000 study reported in the Archives of Internal Medicine reports that 77 percent of Americans are vitamin-D deficient. Numerous studies have shown D's crucial role in;
* strengthening bones
* fighting depression
* boosting immunity
* improved cardiovascular function
* hypertension
* asthma
* weight loss
It is best to consult with your health practioner before beginning any supplement therapy
