They are mostly obtained from the foods we eat but some vitamins like K and biotin are produced by microorganisms in the intestine commonly known as ‘gut flora’. Vitamins are needed in very small quantities. They are made up of carbon, oxygen and hydrogen. They can also contain nitrogen, sulfur, phosphorus and other elements.


Vitamin deficiencies


Deficiencies of vitamins are classified as either primary or secondary. A primary deficiency occurs when an organism does not get enough of the vitamins in its food such as metabolic causes. A secondary deficiency may be due to an underlying disorder e.g due to lifestyle choices like smoking, excess alcohol consumption or medication that interacts with vitamins. There can be times where one experiences deficiencies and thus it is important to acquire the necessary vitamins through foods, supplements or medication.
