How can my skin indicate if I have a vitamin A deficiency?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
The following skin test may indicate if you are getting enough vitamin A. This important vitamin helps your body form and maintain healthy skin, teeth and bones. It also helps your immune system stop and kill germs as soon as they come in contact with your body.
This test will require you to do a full-body examination. Look for dry spots around your body. You should especially check for dry, rough, and cracked skin; brittle hair; and peeling or splitting nails.
If you find any of those, you may have a deficiency in vitamin A.
