Health Benefits of Vitamin A

1. Promotes Good Vision

Vitamin A is essential for maintaining good vision. It plays a vital role in the formation of visual pigments, which are necessary for seeing in low light conditions. A deficiency of Vitamin A can cause night blindness, a condition in which it becomes difficult to see in dim light. Consuming enough Vitamin A can prevent this condition and promote healthy vision.
