I. Introduction
Brief overview of Vitamin C
Vitamin C, also known as ascorbic acid, is a vital nutrient that plays numerous roles in maintaining the body’s overall health. This water-soluble vitamin is essential for the growth, development, and repair of all body tissues. It is a powerful antioxidant that helps protect cells from damage caused by free radicals. Unlike some other vitamins, the human body does not produce Vitamin C, making it crucial to obtain it from dietary sources.
