Vitamins: Their Functions and Sources

Vitamin deficiency is the condition of a long-term lack of a vitamin. When caused by not enough vitamin intake it is classified as a primary deficiency , whereas when due to an underlying disorder such as malabsorption it is called a secondary deficiency. An underlying disorder may be metabolic — as in a genetic defect for converting tryptophan to niacin — or from lifestyle choices that increase vitamin needs, such as smoking or drinking alcohol. Conversely hypervitaminosis refers to symptoms caused by vitamin intakes in excess of needs, especially for fat-soluble vitamins that can accumulate in body tissues. The history of the discovery of vitamin deficiencies progressed over centuries from observations that certain conditions — for example, scurvy — could be prevented or treated with certain foods having high content of a necessary vitamin , to the identification and description of specific molecules essential for life and health. During the 20th century , several scientists were awarded the Nobel Prize in Physiology or Medicine or the Nobel Prize in Chemistry for their roles in the discovery of vitamins.

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.
