Vitamins are organic compounds that the body needs to function properly. Although vitamins are not a source of energy, their role in maintaining health cannot be overestimated. They participate in many biological processes, support the immune system, skin and hair health, and help fight fatigue and stress. In this article, we will look at how vitamins affect health and why their deficiency can lead to serious consequences.
1. Vitamins and the immune system
One of the key functions of vitamins is to support the immune system. Vitamins help the body effectively fight infections, viruses and bacteria.
