Vitamin A takes its active form as retinol, which we typically get from foods from animals, such as eggs, liver, dairy products, and fish oil (Benardot, 2006). Beta carotene has been established as a precursor for vitamin A, so consuming foods rich in this carotenoid is another way to obtain vitamin A in the diet (Benardot, 2006). This discussion post concerns itself with the positive and negative effects on the body, particularly how they relate to athletes.
