AFFECTS

Vitamain CVitamin C is a nutrient valuable for tissue growth, protection of cell membranes from toxic wastes, wound healing, and, as mentioned, support of the immune system. It supports the growth of collagen and cartilage, protecting in this way against many of the effects of aging.

As an antioxidant, vitamin C helps combat free radicals, and it may help with cancer, high cholesterol, cataracts, diabetes, allergies, asthma, and periodontal disease.
The effectiveness of vitamin C is believed to be increased when taken with vitamin E.

DOSES
The recommended daily intake of Vitamin C is 60 mg per day for adults, although many people, following Dr. Pauling's lead, take much higher doses in hopes of preventing colds and warding off the effects of aging. However, in higher doses there may be some toxicity with one of the side effects being diarrhea. In some cases, higher doses of vitamin C may cause kidney stones or anemia, due to an interference with the absorption of vitamin B12.

A reminder: vitamin C is water soluble, and unused portions will be flushed from the body, so daily intake of foods rich in vitamin C or supplementation with a multivitamin may be of value.

While there do not seem to be major problems associated with an high doses of Vitamin C, it might a good idea to stick within recommended daily allowances since the jury is still out on side effects.

DEFICIENCIES
The most well-known result of a vitamin C deficiency is scurvy, a condition characterized by weakness, anemia, gum disease, and skin lesions. Fortunately, scurvy is very rare in our modern society although still found to a greater degree in areas of poor nutrition.

Frequent infections, severe colds, nose bleeds, tiredness, and painful joints may also indicate a deficiency.
