vitamin intake

Different types of vitamins are a mandatory part of a well-balanced diet. They are essential micronutrients that the human body needs in small quantities.

The main role of vitamins is to serve as coenzymes in a variety of metabolic reactions, and an inadequate intake can lead to specific deficiencies.
