The majority of people do not have enough natural vitamin sources in their diet, they therefore suffer from a deficiency of one or more vitamins. Obviously, it is possible to buy vitamin supplements to help overcome any deficiencies but for the majority of people it should be possible for them to obtain the majority of their (RDA)recommended daily allowance of vitamins from Natural Vitamin Food Sources. The key to gaining the correct amount of vitamins from a Natural Vitamin Food Source is to eat a healthy and balanced diet. Diets, such as vegetarian, only provide a limited number of natural vitamins so therefore a supplement may be necessary. Also, the intake required of these Natural Vitamin Food Sources at certain periods may need to be increased and a supplement may be the best option. It is important to be aware of each of the different types of vitamins and their best Natural Vitamin Food Sources so that a person can incorporate as many of these as possible into their regular diet. Water soluble vitamins cannot be stored in the body and need to be replenished on a daily basis so the Natural Vitamin Food Source for these specific vitamins are the most essential to know.

The Sunlight Vitamin
Sunlight is composed of electromagnetic radiation of varying wavelengths, ranging from the long-wavelength infrared light to the short-wavelength ultraviolet. The ultraviolet light is further subdivided into UVA and the even shorter-wavelength UVB radiation. Although UVB causes sunburns, it is also the component that initiates Vitamin-D production in the skin. As such, scientists now believe that past sunscreen use actually promoted skin damage, while, at the same time, blocking beneficial vitamin-D production. (Sunscreen reduces the skin’s ability to produce vitamin D by at least 95%.)

The process by which vitamin D is produced and exerts its biological effects is complicated, involving several vitamin-D-related molecules. Basically, UVB light triggers a modification of a cholesterol-related molecule located in the membrane of skin cells. The vitamin D that is created is then ejected from the membrane into our circulation system, where it travels to the liver. In this organ, it is transformed into 25-hydroxyvitamin D, the derivative that doctors use to assess overall vitamin-D status.
The kidney, as well as some other tissues, further converts this precursor into 1,25-hydroxyvitamin D, the most physiological active vitamin-D metabolite, which is also called calcitrol. Traditionally, calcitrol is understood as a hormone that, together with parathyroid hormone, regulates blood calcium levels and, in turn, bone density. In this role, calcitrol targets the intestine, where it promotes calcium absorption; and bone, where it catalyzes calcium release to help restore depleted blood calcium levels.
However, recent studies indicate that viewing calcitrol just in this role is quite limited. In fact, the hormone exerts a plethora of biological effects on diverse tissues, implying that this sunlight-generated hormone sustains health throughout the body.
Although much remains to be understood, basically, circulating calcitrol enters cells and complexes with the genes in the cell nucleus. This affects DNA expression and, in turn, overall cell functioning and growth. Because calcitrol maintains normal cell proliferation, it inhibits cancerous growth. In addition, calcitrol influences immune-cell activity, helping to explain vitamin D’s seemingly beneficial role in infectious disease and immune-related disorders, such as multiple sclerosis, rheumatoid arthritis, and diabetes.
Given these considerations, the implications of preventing vitamin-D deficiency, either through sunlight or diet, are now more profound than ever.
