Vitamin D is a fat soluble compound that assists the human body to improve calcium absorption. Calcium is needed for healthy development of bones and also to prevent bone related dilapidation. The primary source of Vitamin D for the body is through sunlight. Exposure to sunlight triggers the Vitamin D development in the body which in turn is synthesized in the liver and is subsequently used. Sometimes, Lack of adequate sunlight expose or even lack of adequate sunlight might bring about a shortfall of Vitamin D in the body. Foods with vitamin D content can help people overcome this problem.

Vitamin D is not a naturally occurring substance and is not so very prevalently available in the natural world. However, there are certain types of food that have been used traditionally as supplements and the most popular one is cod liver oil. This oil is naturally equipped to provide the human body with the necessary Vitamin D, apart from other vital minerals. Cod liver oil is available in the form of capsules or syrups. The capsule form is the most popular and ingesting it does not cause any side effects. Not all manufacturers of cod liver oil have Vitamin D in them. It is advisable to check the composition of the manufacturer before buying the product.

Amongst the few naturally occurring foods with vitamin D content, Fish has the maximum percentage of this vitamin that can be absorbed by the human body. Mackerels, herrings and other variety of small fishes, provide the vitamin content to the body. A typical herring food preparation can provide the entire vitamin D requirement for one day. However, it is not necessary to ingest daily quantities of this vitamin because the human body has the capacity to store it and break it down for further use whenever required. It is important to ensure that there is adequate amount of Vitamin D stored in the body.

Foods with vitamin D content can only provide the required amount of this vitamin. But, the vitamin has to be broken down further for it to be used by the body. This is possible only via sunlight. Adequate exposure to light, more specifically the UV rays of the sun, is essential for this break down process. Normally, the exposure to sunlight that we naturally get during the course of the day is enough for this process to be triggered and completed.
