Which vitamin is largely associated with dairy and is important for vision?

Vitamin A is the vitamin that is largely associated with dairy and is crucial for vision. This vitamin plays a vital role in the formation of rhodopsin, a protein in the eyes that allows for vision in low-light conditions. Additionally, Vitamin A is essential for maintaining healthy skin and mucous membranes, and it contributes to overall health and immune function. Dairy products, such as milk and cheese, are excellent sources of Vitamin A, particularly when they are fortified.

While Vitamin E contributes to overall health and has antioxidant properties, and Vitamin K is important for blood clotting and bone health, neither of these vitamins has the same direct association with vision as Vitamin A does. Vitamin C is important for many body functions, including the immune system and collagen production, but it does not play a key role in vision. Thus, Vitamin A stands out as the key nutrient linked with dairy that is significant for maintaining healthy eyesight.
