Vitamin D

Introduction

A fat-soluble vitamins, vitamin D is two main forms that are Vitamin D2 or ergocalciferol or cholecalciferol Vitamin D3 and. Vitamin D2 is synthesized by plants while vitamin D3 is synthesized by the body. Vitamin D is naturally present in a number of food sources and dietary supplements, and is also manufactured using exposure sun. It is produced in the body when ultraviolet B or UVB rays reach the skin. The liver and kidney help convert any vitamin D to active hormone form.

Functions of vitamin D

Vitamin D plays many roles Key in the maintenance of organ systems. For example:

* Vitamin D helps regulate calcium levels in the blood. As it works like a hormone in its active form, calcitriol acts with parathyroid hormone or PTH. If the calcium level is low, this would trigger the secretion of PTH, which stimulates the conversion of vitamin D to calcitriol. Calcitriol would then act to increase calcium absorption in the intestine, resorption of calcium in the kidneys and stimulates the release of calcium from bone.

* Vitamin D helps to keep blood phosphorus levels. Low levels of vitamin D can cause an overactive parathyroid gland. Also with the lack of phosphorus in the body, can not undergo bone mineralization normal.

* It is also said that vitamin D benefits from the immune system T-cells or immune cells have receptors of vitamin D. It works by stimulating phagocytosis, the functions of the body to fight against tumors, neuromuscular and modulate immune function and reduce inflammation.

* Vitamin D is also responsible for maintaining normal cell growth and function. It can be an important element of prevention and treatment of cancer. It was also suggested that vitamin D plays a role in regulating the growth and function of brain cells.

* Studies suggest that vitamin D because of its anti-inflammatory effect, plays a role in protecting against osteoporosis, hypertension, cancer, type 1 diabetes, psoriasis and many autoimmune diseases.

Deficiency conditions

There may be some underlying causes of vitamin D. It can result from:

* Lack of vitamin D taken with insufficient exposure to sunlight

* Some conditions that compromise vitamin D absorption

* Conditions that may affect the conversion of vitamin D metabolites such as kidney disease or liver disease or inherited disorders.

Insufficient intake of vitamin D can have serious effects on bone, which can make them thin, brittle or deformed. Vitamin D deficiency often results in conditions such as:

* Rickets is common in children and is characterized by growth retardation and deformities of long bones.

* Osteomalacia, which occurs in adults and results in the thinning of bones. Signs of proximal weakness and bone fragility are familiar features.

* Osteoporosis is a condition in which bone mineral density bone is reduced and bone fragility is increased.

<p> Lack of vitamin D may also be related to susceptibility increased number of chronic diseases like hypertension, cancer, tuberculosis, periodontal disease, multiple sclerosis, chronic pain, schisophrenia disorders, depression, emotional, peripheral arterial disease and a number of autoimmune diseases such as type 1 diabetes. </ P>

Deficiency symptoms in adults and infants

Signs of vitamin D deficiency include muscle pain, muscle weakness myopathy and bone pain. These symptoms can occur at any age. Pregnant mothers who are deficient in vitamin D deficiency may also cause fetal.

In young children, rickets may produce a condition called craniotabes or softening of the skull. In older infants, rickets may prevent delay or sit and crawl and the closure of the fontanel; moguls of the infant skull and the presence of a costochondral thickening or what is called the "rachitic rosary. Children with rickets enlargements 1-4 years old experience epiphyseal cartilage in the long bones and delayed walking. Older children and adolescents may experience pain in walking and in the worst cases it can lead to "bowlegged" or "knock-knees.

Tetany is caused by hypocalcemia can be combined with a vitamin D deficiency in infants and adults. This condition can lead to symptoms such as loss of sensation in the lips or tongue areas and fingers, facial spasms, and at worst, seizures.

Daily dose Vitamin D

Doses or vitamin D is determined according to age groups. These amounts are essential to maintain normal growth and bone health and normal calcium metabolism in the body. Adequate intake or AI for vitamin D shown are based on the assumption that vitamin D is not synthesized by sun exposure.

From birth to 13 years, IA has recommended for children is of 5 mcg or 200 IU for men and women aged 14-50 years, 5 mcg or 200 IU is necessary for men and women aged 51-70 years, 10 mcg or 400 IU is necessary, the men and women who have attained the age of 71 years and older need 15 mcg or 600 IU of vitamin D. Pregnant women and nursing mothers have need 5 mcg or 200 IU of the vitamin.

Food sources of vitamin D

Only source of food containing vitamin D. some Best sources of vitamin D are fish meat and fish liver oils. There are also small amounts of vitamin D in the form of vitamin D3 found in dairy products like cheese and eggs and beef and liver. Some types of mushrooms also contain varying amounts of vitamin D2.

Sources Common vitamin D are:

* Cod liver oil

* Fish such as salmon, mackerel, tuna, sardines

* Including non-fat milk, low fat, whole or enriched with Vitamin D

* Margarine

* Cereals

* Egg

Beef liver *

* Swiss Cheese

* Orange juice fortified

* Fortified rice or soy milk

The Need for increased quantities

Since obtaining sufficient quantities of vitamin D in the diet can be quite difficult, many people now consume vitamin D enriched foods to maintain a good dose of the vitamin. But there are some groups who need increased amounts of vitamin D:

* Breastfed infants because vitamin D can not be provided by feeding the milk alone

* Seniors due to the fact that the synthesis of vitamin D decreases with age and the kidney's ability to convert vitamin D decreases

* People with low sun exposure in particular those living in northern latitudes, these dresses or wear head covers or those with occupations that prevent them from having Sun Exposure

* People with dark skin pigments such as melanin, the skin reduces the ability of the skin produce vitamin D.

* People with fat malabsorption conditions such as Crohn's disease, cystic fibrosis, liver and celiac disease or patients who underwent surgical removal of part of the stomach or intestine.

* People who are obese. Greater amount of subcutaneous fat can pull more of vitamin D and somehow change his release into the circulation.

Interaction of vitamin D Prescription Drug

Vitamin supplements of vitamin D tend to react with certain types of prescription drugs. These are:

* Steroids or corticosteroids like prednisone, which may cause decreased absorption of calcium and also damage the process of metabolism of vitamin D.
* Drugs such as weight loss orlistat and cholesterol-lowering drugs like cholestyramine also decrease the absorption of vitamin D and other fat-soluble vitamins.
* Phenobarbital and phenytoin increases the metabolism of vitamin D and decreased calcium absorption.
