Vitamin C is crucial for the synthesis of collagen in the body. Collagen is a vital protein that provides structure and elasticity to tissues such as skin, cartilage, and bones. Vitamin C serves as a co-factor in the enzymatic reactions necessary to stabilize collagen molecules. Deficiency in this vitamin can lead to impaired collagen synthesis and conditions like scurvy, which manifest through weakened connective tissues. Therefore, ensuring adequate intake of Vitamin C through diet or supplements is essential for healthy collagen production and overall skin and joint health.
