Are nutrients that should be considered as an organic compound.
Often they are synthesized by the organism itself and are essential to metabolism.
When the organisms do not produce enough vitamins alone - the remaining vitamins must be obtained through diet.
The word “vitamin“ is a very general term that does not encompase all compounds.
Certain foods therefore are much more rich in vitamins then others.
The health associated with vitamins has a long history.
