Not just important for the immune system

Vitamin C and zinc perform many tasks in the human body. They support the body’s immune system and protect cells from free radicals and oxidative stress.5 Vitamin C also contributes to normal energy metabolism, normal nervous system function, and iron absorption.6 In addition, the body needs to receive an adequate supply of this essential vitamin in order to maintain healthy bones.

Not only is zinc is essential for the body’s own defenses, but it also plays a role in cell division. Moreover, it is necessary for healthy skin, hair, and nails. This trace element is also involved in the metabolism of carbohydrates, proteins, and vitamin A synthesis.7,8
