Natural sources of vitamin D:

Vitamin D is classified as a fat soluble vitamin. It is naturally available in different types of fruits, vegetables and other plant parts. It can also be synthesized within the body after exposure to the ultra violet of the sun. Of all the natural sources of vitamin D sunshine is considered to be the most significant one because of the fact that the Ultra violet from the sun triggers vitamin synthesis within the skin. Scientific research and studies conducted in this regard suggests that exposure to sunlight provides most of the humans with the vitamin requirement. Other than this nature has provided ample source of this vitamin in varied food sources, the most prominent of which are the fortified foods that primarily includes milk. The cereals also act as a good source of the same as most of the cereal grains fortified with it.

Vitamin D: important nutrient for the body.

Vitamin D is an important vitamin for the body and it catalyses the various biochemical synthesis. It resulted into the formation of various metabolites which is very much essential for the all round development of the body. Since the discovery of vitamin, continuous research on it is going on. this research and experiments has revealed various important facts about vitamin .it is found out that vitamin D can prevent various forms of diseases starting from bone disorder to cancer and still research is going on and there is only need to keep our finger crossed to get some another good news about it.

Introduction

Vitamin D is a sunshine vitamin. It is a fat soluble vitamin and is not soluble in water. This vitamin is used to absorb calcium and phosphorous from the different parts of the body. This vitamin is also needed to keep the bones and teeth healthy as it absorbs calcium. It helps in passing of impulses to the brain. The easiest and most freely available source is the ultraviolet rays or the sun what we usually called. It also maintains the insulin level in the blood stream.

Functions of vitamin D:

One of the most important and major biological functions of vitamin D is to maintain appropriate levels of calcium and phosphorus in human blood. Calcium is vital in the strengthening of the bones and phosphorus is needed in maintaining good teeth and bones and for the proper functioning of the nerves of the muscles. Vitamin D is very essential for the body as it aids in the absorption of calcium, which helps in the formation, and the maintenance of strong bones and without it the bones may become thin, brittle and soft along with other deformations. Vitamin becomes more important with the increase in the age, for not only the strength of the bones but also the teeth. In a study that was recently conducted in the United States it has been found out that men and women over the age group of 50 years who lack in this vitamin has significantly increased chances of having the periodontal diseases that accounts for the common chronic inflammation of the gums and causes the loss of tooth. Vitamin is also effective in controlling the growth of cells.

Briefly about vitamin D

Vitamin D is a fat-soluble vitamin and mostly found in eggs and fishes; it is highly nutritious for the body. Vitamin D acts as a catalyst in our body and activates various metabolic processes. The essential metabolites formed are carbohydrates and fatty acids, which is very helpful for the body. Vitamin D is mostly related with calcium and phosphorous content of the body. Calcium and phosphorous are also very important and helps in all round development of the body. Calcium is mainly responsible for keeping the bones healthy and its deficiency causes various disorders in bones. Taking various dietary supplements rich in vitamin D can enhance vitamin D level in the body. In some cases various medicines, which are rich in vitamin, are also taken to bring the body up to normal level as vitamin D is concerned. Vitamin D can also be obtained from sunlight and therefore daily exposure to sunlight for some time is important to keep the body free of disorder in bones.

MS basically is the abbreviation of the medical term of multiple sclerosis. The cause of multiple sclerosis involves immune attacks against the body's own brain and spinal cord tissues, is unknown. Worldwide, multiple sclerosis takes place with much less frequency in lower latitudes closer to the equator, than in higher latitudes, further away from the equator. It is believed that there may be genetic, infectious, and environmental factors that increase or decrease an individual's risk of developing multiple sclerosis. One of numerous possible protective factors at work in lower latitudes, which are being explored, is the increased sunlight exposure in these areas and the resulting increase in the body's production of vitamin D. Vitamin D is accessible not only through sun exposure but also from nutritional sources and vitamin supplementation.

In order to lead a healthy life it is very important to eat the right kind of food. This is because; through food we can fulfill the nutrient requirement of our body. Calcium and vitamin D is one such vital mineral. They work in symbiosis and help in developing bones and teeth.

Calcium

Any deformities or diseases of the bone can trace the basic deficiency symptoms of vitamin D. This is because of the fact that vitamin D controls the appropriate levels of calcium and phosphorus in the bones which keeps them in well form and structure. If there is a deficiency than the levels of these minerals within the body are altered and this leads to the deformities. Some of the classic examples of such diseases are rickets, osteoporosis and osteomalacia. Rickets is caused by then vitamin D deficiency and often occurs during the childhood period. It can be easily characterized by a stunted growth of the bones and deformities of the long bones. Osteomalacia occurs only in the mature skeleton and it causes the bones to be fragile and also proximal weakening of the muscles. Studies related to the deficiency of the vitamin may also lead to some serious health complication which, may include cancer of different types mainly breast, ovarian, colon, prostate, lung and skin, diabetes, high blood pressure, mental illnesses and heart diseases among the others.

One of the most essential elements to our body nutrition is Vitamin D. Other names of Vitamin D are D3, sunlight vitamin and NR1|1 antibody. The nutrient is produced naturally in our body when exposed to sunlight. It is also substance required in our body in small but regular amounts through a regular diet. The NR1|1 antibody is also used to prevent some types of cancers and to strengthen the immune system and the bones of our body by increasing the calcium absorption in our body. The rich sources of Vitamin D are all the animal products and salt water fishes where as the poor but effective sources are eggs, beef, butter, vegetable oil and fruits. The absence of this nutrient could cause various types of disease in our body.

Importance of Vitamin D: -

One of the most essential elements to our body is Vitamin D. It is also known as sunlight vitamin, D3 and NR1|1 antibody. Exposure of the body to sunlight or ultra-violet rays produces Vitamin D within our body. D3 is a substance required by the body in small but regular amounts through a regular diet. The NR1|1 antibody is used to prevent some types of cancers and to strengthen the immune system and the bones of our body by increasing the calcium absorption.

25 hydroxy Vitamin D is commonly known as Vitamin D. It is a fat soluble vitamin that is found in food. 25 hydroxy Vitamin D can also be made in our body after exposure to ultraviolet (UV) rays from the sun. Vitamin D is exists in different forms. Each form of Vitamin D has a different level of activity. Calciferol is relatively most active form of Vitamin D. Vitamin D needs a chemical conversion in the liver and kidney to make the physiologically active form of vitamin D. Active vitamin D works similar to a hormone because it increases the absorption of calcium and phosphorus in the intestine. The foremost biological function of 25 hydroxy Vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D promotes the calcium absorption to form and maintain strong bones. Vitamin D also works with a number of other vitamins, minerals, and hormones to promote bone mineralization.
