A Harvard Health article. Vitamins and minerals are essential nutrients because they perform hundreds of roles in the body. There is a fine line between getting enough of these nutrients which is healthy and getting too much which can end up harming you. Eating a healthy diet remains the best way to get sufficient amounts of the vitamins and minerals you need. Every day, your body produces skin, muscle, and bone.

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. For this reason, vitamins are called essential nutrients. Vitamins also differ from the other biological compounds in that relatively small quantities are needed to complete their functions.

If a vitamin is absent from the diet or is not properly absorbed by the body, a specific deficiency disease may develop. Vitamins are usually designated by selected letters of the alphabet, as in vitamin D or vitamin C , though they are also designated by chemical names, such as niacin and folic acid.

Biochemists traditionally separate them into two groups, the water-soluble vitamins and the fat-soluble vitamins. The common and chemical names of vitamins of both groups, along with their main biological functions and deficiency symptoms, are listed in the table.

Some of the first evidence for the existence of vitamins emerged in the late 19th century with the work of Dutch physician and pathologist Christiaan Eijkman. In a nerve disease polyneuritis broke out among his laboratory chickens. He noticed that the disease was similar to the polyneuritis associated with the nutritional disorder beriberi.

In he demonstrated that polyneuritis was caused by feeding the chickens a diet of polished white rice but that it disappeared when the animals were fed unpolished rice. In —07 British biochemist Sir Frederick Gowland Hopkins observed that animals cannot synthesize certain amino acids and concluded that macronutrients and salts could not by themselves support growth. Funk believed that some human diseases, particularly beriberi, scurvy , and pellagra , also were caused by deficiencies of factors of the same chemical type.

Later it was realized that the water-soluble growth factor , vitamin B, was not a single entity but at least two—only one of which prevented polyneuritis in pigeons. The factor required by pigeons was called vitamin B 1 , and the other factor, essential for rats, was designated vitamin B 2. As chemical structures of the vitamins became known, they were also given chemical names, e. Vitamin Article Media Additional Info. Article Contents. Print print Print. Table Of Contents.

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.

The list of vitamins and minerals below can give you an understanding of how particular different types of vitamins and minerals work in your body, how much of each nutrient you need every day , and what types of food to eat to ensure that you are getting an adequate supply. The recommendations in this vitamins chart are based largely on guidelines from the Institute of Medicine. Recommended amounts of different types of vitamins may be expressed in milligrams mg , micrograms mcg , or international units IU , depending on the nutrient.
