Vitamin , any of several organic substances that are necessary in small quantities for normal health and growth in higher forms of animal life. Vitamins are distinct in several ways from other biologically important compounds such as protein s, carbohydrate s, and lipid s. Although these latter substances also are indispensable for proper bodily functions, almost all of them can be synthesized by animals in adequate quantities. Vitamins, on the other hand, generally cannot be synthesized in amounts sufficient to meet bodily needs and therefore must be obtained from the diet or from some synthetic source.

The tables below list the vitamins , what they do in the body their functions , and their sources in food. Water-soluble vitamins travel freely through the body, and excess amounts usually are excreted by the kidneys. The body needs water-soluble vitamins in frequent, small doses. These vitamins are not as likely as fat-soluble vitamins to reach toxic levels. But niacin, vitamin B6, folate, choline, and vitamin C have upper consumption limits. Vitamin B6 at high levels over a long period of time has been shown to cause irreversible nerve damage. A balanced diet usually provides enough of these vitamins.
Multiple signs are therefore seen, although in general, signs of B vitamin deficiencies appear first. Because there are some stores of fat-soluble vitamins in the body, it often takes longer for these deficiencies to affect the bird, and it may take months for vitamin A deficiency to affect adult birds. Treatment and prevention rely on an adequate dietary supply, usually microencapsulated in gelatin or starch along with an antioxidant. Vitamin destruction in feeds is a factor of time, temperature, and humidity. For most feeds, efficacy of vitamins is little affected over 2-mo storage within mixed feed.

Vitamin D overview
Vitamin D is one of the essential nutrients to sustain the human health. As a member of the steroid hormone family, it has a classic role in regulating metabolism of calcium and a non-classic role in affecting cell proliferation and differentiation. Epidemiological studies have shown that 25OHD deficiency is closely associated with common chronic diseases such as bone metabolic disorders, tumors, cardiovascular diseases, and diabetes. It is therefore necessary to know the adverse health effects of 25OHD deficiency, and to design interventions and early treatments for those who are likely to have low levels of 25OHD. Many studies have demonstrated that Vitamin D has multiple effects on biological processes regulating calcium and phosphorus metabolism as well as effects on cell proliferation, differentiation, apoptosis, immune regulation, genome stability, and neurogenesis. Recent studies have also found that Vitamin D is closely associated with cardiovascular diseases, diabetes, cancers, autoimmune diseases, infectious diseases, and others [ 1 , 2 ].
