what are the functions of vitamin d in the body?
58070
Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth and muscles healthy. A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain caused by a condition called osteomalacia in adults.

Vitamin D. Definition, importance, forms. A group of sterol compounds which have a vital role in bone metabolism. Vitamin D and parathyroid hormone are the main regulators of calcium and phosphorous in the body.

Vitamin D, nicknamed the sunshine vitamin because your body produces it after sun exposure, has long been known to help build strong bones by increasing the body's absorption of calcium and phosphorous.

A human body produces vitamin D as a response to sun exposure. A person can also boost their vitamin D intake through certain foods or supplements. Vitamin D is essential for several reasons, including maintaining healthy bones and teeth.

Vitamin D is a hormone the kidneys produce that controls blood calcium concentration and impacts the immune system. It is also known as calcitriol, ergocalciferol, calcidiol and cholecalciferol. Of those, calcidiol is the form doctors most commonly focus on when measuring vitamin D levels in the blood.

Vitamin D is actually a hormone rather than a vitamin; it is required to absorb calcium from the gut into the bloodstream. Vitamin D is mostly produced in the skin in response to sunlight and is also absorbed from food eaten (about 10% of vitamin D is absorbed this way) as part of a healthy balanced diet.

Often called the 'sunshine vitamin', vitamin D plays an integral role in skin protection and rejuvenation. In its active form as calcitriol, vitamin D contributes to skin cell growth, repair, and metabolism. It enhances the skin's immune system and helps to destroy free radicals that can cause premature ageing.

Vitamin A is involved in what additional functions in the body? Some other functions of Vitamin A include bone development, reproduction, immune function (T-Cells, antibodies, natural killer cells, Antioxidane activity (betia carotene).

Summary: One of vitamin D's main functions is to ensure adequate levels of calcium in your blood. Vitamin K promotes calcium accumulation in your bones, while reducing its accumulation in soft tissues such as blood vessels.

Vitamins. Vitamins are substances that our bodies need to develop and function normally. They include vitamins A, C, D, E, and K, choline, and the B vitamins (thiamin, riboflavin, niacin, pantothenic acid, biotin, vitamin B6, vitamin B12, and folate/folic acid).

These vitamins are essential for a fully functioning metabolism. The main function of the B vitamins is to help your body metabolize carbohydrates, proteins, and fats, and to use the stored energy in food. Thiamine (B-1), for example, helps the body cells convert carbohydrates into energy.

Vitamin D is used to treat and prevent bone disorders (such as rickets, osteomalacia). Vitamin D is made by the body when skin is exposed to sunlight. Sunscreen, protective clothing, limited exposure to sunlight, dark skin, and age may prevent getting enough vitamin D from the sun.

The sun's rays provide ultraviolet B (UVB) energy, and the skin uses it to start making vitamin D. (The skin actually produces a precursor that is converted into the active form of the vitamin by the liver and kidneys.) Vitamin D is best known for its vital role in bone health.

PHYSIOLOGIC FUNCTIONS OF VITAMIN D The vitamin D hormone functions to increase serum calcium concentrations through 3 separate activities. First, it is the only hormone known to induce the proteins involved in active intestinal calcium absorption. Furthermore, it stimulates active intestinal absorption of phosphate.

Vitamins D and K are both fat-soluble vitamins and play a central role in calcium metabolism. Vitamin D promotes the production of vitamin K-dependent proteins, which require vitamin K for carboxylation in order to function properly.
