Vitamin C (also known as ascorbic acid) is abundant in vegetables and fruits. A water-soluble vitamin and powerful antioxidant, it helps the body form and maintain connective tissue, including bones, blood vessels, and skin.

Why is vitamin C necessary?
Many do not know all of the facts on vitamin C, which helps to repair and regenerate tissues, protect against heart disease, aid in the absorption of iron, prevent scurvy, and decrease total and LDL ("bad") cholesterol and triglycerides. Research indicates that vitamin C may help protect against a variety of cancers by combating free radicals, and helping neutralize the effects of nitrites (preservatives found in some packaged foods that may cause cancer). Supplemental vitamin C may also lessen the duration and symptoms of a common cold; help delay or prevent cataracts; and support healthy immune function.

What are the signs of a deficiency?
The facts on vitamin C tell us that deficiency symptoms include fatigue, muscle weakness, joint and muscle aches, bleeding gums, and leg rashes. Prolonged deficiency can cause scurvy, a rare but potentially severe illness.

How much, and what kind, does an adult need?
According to the National Institutes of Health (NIH), the recommended daily intake for adults is 90 mg per day for men and 75mg for women (85 mg during pregnancy, 120 mg while breastfeeding). Smokers may benefit from a higher intake. Dr. Talebi recommends taking 250 mg of vitamin C each day, or higher doses - greater than 1,000 mg per day – for additional protection against the oxidative effects of air pollution and smoke.
