Vitamins

Vitamins are a group of organic compounds that are extremely necessary and essential for normal growth and functioning of the human body. They are required in very small quantities but cannot be synthesized by the body itself, and can only be sourced from outside.

Whereas they are not possible to be synthesized in our bodies they are easily synthesized in plants. So we must rely on these sources for our daily requirements of vitamins. Like for example, we eat oranges and lemons for Vitamin C. So all our vitamins are obtained via our diet or other supplements.

As the name suggests these are soluble in lipids i.e. in fats. They are insoluble in water. Their absorption into the bloodstream happens in the intestines. They are stored in human bodies as adipose tissues in the liver. Fat-soluble types of the vitamin are not easily excreted, Hence it is very much possible to overdose on them if they reach toxic levels in your body, This disease is hypervitaminosis. The fat-soluble vitamins are Vitamin A, D, E and K.
