The Sun causes the synthesis of Vitamin D in the skin.
Your skin is responsible for synthesis of Vitamin D.
vitamin D
synthesis of a Vit. D
Low vitamin D levels can be caused by several factors, including insufficient sun exposure, which is essential for the body's natural synthesis of the vitamin. Other contributing factors include a diet low in vitamin D-rich foods, certain medical conditions that affect absorption (like celiac disease or Crohn's disease), and obesity, which can sequester vitamin D in fat tissue. Additionally, older adults and individuals with darker skin may have reduced synthesis of vitamin D due to lower UVB absorption.
The building block of steroid hormones and vitamin D is cholesterol. Cholesterol serves as the precursor molecule for the synthesis of these important biological compounds in the body.
Several factors: 1. Weight bearing exercise 2. adequate calcium intake 3. Sun exposure (for vitamin D synthesis. Calcium cannot be absorbed without vitamin D) 4. Balanced diet, including an adequate intake of all essential nutrients. 5. Don't do drugs, some on them can inhibit proper growth and development in general. The majority of bone health and mass is accrued during adolescent years, so the best time to strengthen bones is during adolescence.
Vitamin D improves the absorption of zinc, magnesium, calcium and phosphate in the body. This vitamin prevents rickets and improves the health of bones.
The amount of vitamin D that can be made by the body is limited by factors such as sun exposure, skin pigmentation, age, geographic location, clothing coverage, and the use of sunscreen. Additionally, certain medical conditions or medications can affect the body's ability to produce vitamin D.
Julie Elizabeth Seymour has written: 'A novel approach to the synthesis of vitamin D'
Vitamin D is very important. The primary source of vitamin D is the sun. The foods that most if is eats is not enough for our body. Vitamin D aids in the absorption of calcium, which in turn helps maintain bone density. When your bone density becomes too low then you are much more susceptible to osteoporosis.
Vitamin D deficiency not only causes metabolic bone disease among children and adults but also may increase the risk of many common chronic diseases. Without Vitamin D, the bloodstream cannot absorb calcium from the digestive tract. Without calcium, bone tissue will slowly wear away.
