Vitamin C is an amazing source of antioxidant protection that serves to increase our immunity and aid in cellular renewal. Vitamin C is found in fruits and vegetables and also works to prevent a host of diseases including cardiovascular disease, cancer(s), and diseases of the eye and skin. Adults should strive to eat at least 5 servings of fruits and vegetables per day or take a vitamin C supplement providing the recommended 75-90 milligrams of vitamin C as Ascorbic Acid. The best natural food sources of vitamin C include all citrus fruits, orange juice, red peppers, cantaloupe, broccoli, red cabbage, green peppers, kiwi, and tomatoes.
Recent studies from the University of Michigan have concluded that high levels of vitamin C, as measured by the blood, may be the most telling nutrition marker for overall health and wellness. Vitamin C was also reported to aid in longevity and to offer increased protection from diseases when taken in amounts greater than the daily USDA recommended dosage. Vitamin C is water soluble and excreted from the body through urination, because of this, vitamin C is classified as a non-toxic nutrient and safe in large dosages. High dosages of vitamin C exceeding the recommended USDA upper limits might cause diarrhea and gastric discomfort.
