Organic compounds that the body needs in very small amounts for normal growth and maintenance of good health to take place. They play important metabolic roles. There are two groups of vitamins, the fat soluble and the water soluble. Vitamins A, D, E, and K are fat soluble while vitamin C (ascorbic acid) and the vitamin B complex group are water soluble.

Small organic compounds, necessary for proper metabolism, that are found in feed in minute amounts. Deficiencies result in distinct diseases or syndromes.

A group of natural substances that are necessary in certain amounts for the body's growth and good health.

Essential micronutrients that are required in the diet because they cannot be synthesized in the human body. Vitamins can function as antioxidants and coenzymes, compounds necessary for specific reactions in the body.

Organic substance required by the body to regulate cellular function. Vitamins affect all functions of the body, including promoting good vision, forming normal blood cells, and ensuring proper functioning of the heart and nervous system.

The word "vitamin" was coined in 1911 by the Warsaw-born biochemist Casimir Funk (1884-1967). At the Lister Institute in London, Funk isolated a substance that prevented nerve inflammation (neuritis) in chickens raised on a diet deficient in that substance. He named the substance "vitamine" because he believed it was necessary to life and it was a chemical amine. The "e" at the end was later removed when it was recognized that vitamins need not be amines. See the entire definition of Vitamins

(Latin vita = life) | entry to be edited | Vitamins form 2 major classes the fat soluble (D, E, A, and K) and water soluble (B, and C). These organic compounds are required at very low concentrations and function as cellular metabolic regulators. The specific roles for vitamins, other than B (folic acid), during embryonic development (other than in maternal nutrition) is unknown.

Complex organic molecules essential for biochemical transformations necessary for proper metabolism and disease protection. Some popular vitamins are

Vitamins and minerals are drugs that replace or fix low levels of important natural substances in your body. You get vitamins and minerals from food. Some types of food have more of these good substances than others. If you need extra vitamins and minerals, you may have to take pills that have them.

Domesticated cats fulfil their other vitamin requirements from a well-balanced, varied diet, and from the supplements manufacturers add to cat food.

Vitamins are organic compounds that are nutritionally essential in small amounts to control metabolic processes and cannot be synthesized by the body. Vitamins are usually classified by their solubility, which to some degree determines their stability; occurrence in foodstuffs; distribution in body fluids, and tissue storage capacity. Each of the fat-soluble vitamins A, D, E and K has a distinct and separate physiologic role. Several have antioxidant properties to depress the effects of metabolic byproducts called free radicals, which are thought to cause degenerative changes related to aging. Most of the water-soluble vitamins are components of essential enzyme systems. Many are involved in the reactions supporting energy metabolism. These vitamins are not normally stored in the body in appreciable amounts and are normally excreted in the urine. Thus, a daily supply is desirable to avoid depletion and interruption of normal physiologic functions. Ww
