Vitamin C is one vitamin that actually serves as an anti-aging supplement.  Its role as an antioxidant helps to actually reverse the aging process.  Vitamin C is known as the ascorbate ion. In living organisms, ascorbate is an antioxidant, since it protects the body against oxidative stress, and is a cofactor in several vital enzymatic reactions.  In humans, vitamin C is a highly effective antioxidant, acting to lessen oxidative stress, a substrate for ascorbate peroxidase, as well as an enzyme cofactor for the biosynthesis of many important biochemicals.

People consuming diets rich in ascorbate from natural foods, such as fruits and vegetables, are healthier and have lower mortality from a number of chronic illnesses. All fruits and vegetables contain some small amount of vitamin C.  Foods that tend to be the highest sources of vitamin C include green peppers, citrus fruits and juices, strawberries, tomatoes, broccoli, turnip greens and other leafy greens, sweet and white potatoes, and cantaloupe.
Other excellent sources include papaya, mango, watermelon, brussels sprouts, cauliflower, cabbage, winter squash, red peppers, raspberries, blueberries, cranberries, and pineapples.

The results of having too little vitamin C in your diet can lead to dry and splitting hair, rough or dry skin, weakened teeth enamel, anemia, swollen joints, weight gain in some cases and a decreased ability to fight infection.  So, naturally having more vitamin C in your diet will help reverse the effects of aging and help you lead a positively much healthier life.
