Vitamin A is involved in regulating the growth and specialization (differentiation) of virtually all cells in the human body. Vitamin A has important roles in embryonic development, organ formation during fetal development, normal immune functions, and eye development and vision.
The vitamins in your diet also contribute to tissue maintenance. Vitamin A, for example, plays a key role in cell growth by regulating gene activity -- it helps newborn cells activate genes they need to develop into functional tissue. It also plays an important role in building healthy skin tissue and promoting blood cell growth.
