Which vitamin is also known as Retinol?

Retinol is indeed another name for Vitamin A. This vitamin is essential for various bodily functions, including maintaining healthy vision, supporting the immune system, and promoting cell growth and differentiation. Retinol, in its active form, is involved in the process of vision, particularly in the formation of rhodopsin, a pigment in the retina that is crucial for low-light vision.

Vitamin A exists in two primary forms: preformed vitamin A (retinol and its esters), which is found in animal products like liver and dairy, and provitamin A carotenoids, like beta-carotene, which can be converted to retinol in the body and are found in plant foods like carrots and spinach. The body regulates the conversion of carotenoids to retinol based on its needs, demonstrating the importance of this vitamin in maintaining overall health.

The other vitamins listed — Vitamin C, Vitamin D, and Vitamin E — serve different roles in the body. Vitamin C is primarily an antioxidant and important for collagen synthesis, while Vitamin D is crucial for calcium metabolism and bone health. Vitamin E functions mainly as an antioxidant that helps protect cell membranes from damage. Each vitamin has distinct biological functions, but none are synonymous with retinol.
