As you probably know, Vitamin D is a fat soluble vitamin and is an essential nutrient for bone growth and maintaining strong teeth and strong bones. It is also involved in a variety of other essential functions for the human body. Deficiencies of this vitamin can have serious health consequences for both children and adults. When not present in sufficient levels, a person can suffer from a variety of deficiencies resulting in impaired functioning, including impaired vision. Infants who do not get enough Vitamin D in their diet can suffer from:

• Restless sleep and rough sleep patterns• Poor vision• Minimum birth weight• abnormally low bone density, especially in the spine and skull• Osteolmalacia• Chronic joint pain and muscle weakness• Depression•oftentimes, lethargy• confusion• poor memory• reduced appetite• slow growth in children• major depressive disorder in adults

unacceptable levels of Vitamin D in the blood have been linked to all kinds of toxicity. Children are especially sensitive to the levels of Vitamin D that are present in blood and other components of the body and are able to suffer the most serious effects when there is a low level of Vitamin D in blood.

Although the FDA has set an acceptable level for Vitamin D that is adequate for most of the public, the acceptable levels for Vitamin D for some people exceed the FDA limit by more thanosa for heart disease and rickets and osteoporosis.

Major causes of Vitamin D deficiencies include the consumption of fortified foods (such as milk), tanning and excessive sun exposure. In children, a deficiency of Vitamin D can cause rickets, which is characterized by skeletal deformities and growth retardation. In adults, Vitamin D deficiency can cause osteomalacia, which is characterized by low bone mineral density.

The most common means of producing Vitamin D in the body is by exposing the skin to the sun, allowing it to patch up against the skin (except for rare instances when some sun exposure can cause problems). People who live in climates that are hot and humid can make Vitamin D by spending time in the sun, but people who live in colder climates produce small amounts of Vitamin D as well as through exposure to sunshine.

Vitamin D Deficiency is a relatively common deficiency disease worldwide. According to the value of symptoms, children and adults with Vitamin D deficiencies often suffer from:

• Excess weight• brittle nails• brittle hair• nocturnal leg cramps• slow growth in children• osteomalacia• hypoglycemia• poor teeth and gums• recurrent infections

In adults, Vitamin D deficiencies can cause osteomalacia, osteoporosis, depression, anxiety, older-than-life- span, multiple sclerosis, chronic pain and plenty more diseases.

How Does Vitamin D Affect Body composition?

Vitamin D affects body composition (%), which is often sub-optimal for many reasons. Most of the vitamin you get from your diet is through sun exposure, so minimizing the impact of time spent in the sun is the most effective strategy for ensuring you remain healthy.

According to growing international evidence, Vitamin D is a reasonably well-researched topic and it is now widely considered that humans permissible exposure to natural light for renewal of vitamin D is nothing short of harmful, keeping in mind the level of potential danger that could be reaped by those undertaking risky sun exposure (on a limited, reasonable basis).

While those under the age of 18 are prohibited from both consuming all natural food form and consuming vitamin D supplements, appropriately monitored adults should have no trouble reaping the benefits of appropriate sun exposure.

Adequate sun exposure provides an adequate quantity of Vitamin D for the body. As described previously under risk factors, people whose risk of Vitamin D deficiency exceed their ability to cope with the deficiency can benefit from vitamin D supplementation.
