Which vitamin is also known as retinol?

The vitamin referred to as retinol is Vitamin A. Retinol is a form of Vitamin A that is primarily found in animal liver, fish oils, and dairy products. This vitamin plays a crucial role in several important bodily functions, including maintaining healthy vision, supporting immune function, promoting skin health, and aiding in the growth and development of cells.

Vitamin A is essential for the production of rhodopsin, a pigment in the retina that helps the eyes adapt to changes in light. Additionally, Vitamin A is involved in the regulation of gene expression and is important for reproductive health as well as proper functioning of the heart and lungs.

In contrast, the other vitamins listed serve different biological roles and do not share the same characteristics or functions as Vitamin A. For example, Vitamin B1, also known as thiamine, is crucial for carbohydrate metabolism and energy production; Vitamin C is an antioxidant important for collagen synthesis and immune function; and Vitamin E functions primarily as an antioxidant that helps protect cell membranes from oxidative damage. Each of these vitamins has distinct roles that are essential for maintaining overall health.
