Which vitamin is known to have antioxidant functions and is vital for metabolic processes?

Vitamin E is known for its significant antioxidant functions and its vital role in various metabolic processes. As a fat-soluble vitamin, it helps to protect cells from oxidative damage by neutralizing free radicals, which can lead to cellular injury and contribute to the aging process, as well as various diseases. This antioxidant capacity is particularly important in protecting cell membranes from lipid peroxidation, thereby maintaining overall cell integrity and health.

Additionally, Vitamin E is essential for immune system function and is involved in various biochemical processes, including the regulation of gene expression and the modulation of cell signaling pathways. By facilitating these metabolic pathways, Vitamin E plays a crucial role in maintaining overall health and supporting the body's physiological functions.
