Which vitamin is vital for immunity, iron absorption, and protein metabolism?

Vitamin C is vital for immunity, iron absorption, and protein metabolism due to its essential role in various bodily functions. It is known to stimulate the production and function of white blood cells, which are crucial for the immune response. Additionally, vitamin C enhances the absorption of non-heme iron found in plant-based foods, significantly supporting overall iron levels in the body.

Furthermore, vitamin C is involved in the synthesis of collagen, a protein that is crucial for the structural integrity of tissues, thereby playing a role in protein metabolism. It acts as a cofactor in various enzymatic reactions that are essential for converting certain amino acids into protein. This multifaceted role highlights the importance of vitamin C in maintaining immune function, promoting healthy iron levels, and supporting metabolic processes involving protein synthesis.
