Vitamin A | Benefits and Symptoms of Overdose and Deficiency Symptoms

Vitamin A is a crucial vitamin that your body needs to maintain healthy skin and good eyesight.

Think of it as a moisturizer that works from the inside out. Vitamin A works to keep our skin and other mucous membranes from getting dry.

Not only does Vitamin A help keep our skin smooth and supple, it also protects our eyes from age-related degeneration.

Last but not least, Vitamin A encourages our immune systems to use the cells that we need to fight off infections.

It is a credible antioxidant and has been shown to aid in cancer prevention and acts as an active immune system enhancer.

Vitamin A is found naturally in orange and yellow fruits and vegetable as beta-carotene and in animal fats like egg yolks as retinol.

Beta-carotene has strong antioxidant abilities. It helps protect our skin and cells from the many toxic chemicals that we come into contact with on a daily basis.

Retinol is essential to eye health (get it…Retinol-Retina-the retina is in your eye) and is a popular ingredient in beauty products.
