Benefits of Vitamin A
Vitamin A helps to aid a person’s basic vision, a person with an ample amount of Vitamin A is able to see more easily by dim light. A person deficient in Vitamin A will likely lack sufficient rhodopsin. This is found in the retina of the eye, a person lacking in this will struggle to see when light is dim. Due to this, Vitamin A also negates the impact of age-related damage on eyesight.
A deficiency in Vitamin A makes a person more likely to develop skin disorders. This is largely due to Vitamin A aiding in the body’s ability to remove dead skin cells. Without being able to do this, pores become blocked and skin will become itchy and irritated. In more serious cases, a person can develop acne, impacting a person’s self-esteem and even leading to mental health disorders. Due to this, it is not uncommon for medications to treat poor skin health to be rich in Vitamin A.
