    Vitamins A, C, E Mini Profile (Antioxidant Mini Profile)

    Vitamin A

    Some of the functions of vitamin A are in the body's vision, mucous membranes, cell division, skin maintenance, sperm production, egg development, growth, bone development and cancer prevention. Symptoms indicate a deficiency of vitamin A in the body include poor vision, night blindness, "bumps" on skin, lower disease resistance, stunted growth, pregnancy problems, acne, and xerosis.

    Preformed vitamin A is found mainly in animal meats. Beta carotene is composed of two vitamin A molecules and is found in green or orange vegetables, and fruits. These include carrots, squash, spinach, apricots, etc. The RDA for vitamin A is 3000 I.U. per day. A supplemental dose could range from 5000 to 10,000 I.U. A toxic dose may occur at 25,000 to 50,000 I.U. The body will convert beta carotene to vitamin A if the thyroid is functioning properly and the patient does not have diabetes. These two conditions may lead to a high serum beta carotene and low serum vitamin A.

    Vitamin A is measured in serum which must be protected from light.

    Vitamin C - Plasma

    Vitamin C is also called ascorbic acid. There have been over 7000 articles written about vitamin C. It is a strong water-soluble antioxidant. Vitamin C stimulates the immune system in seven different ways and is important in collagen formation. It is important in the synthesis of connective tissue, and in wound healing. It helps regulate lipids in blood, iron absorption and is important in synthesis of hormones in stress situations. It helps regenerate vitamin E in the body. It is found in many fruits and vegetables such as sweet peppers, broccoli, cauliflower, lemons, strawberries, asparagus, spinach, oranges, cantaloupe, grapefruit and tomatoes. Deficiency of vitamin C results in the classical disease of scurvy. Other conditions are pain in joints, slow wound healing, lower disease resistance, easy bruising, bleeding gums, loose teeth, irritability, premature wrinkling and aging of skin. Like most other vitamins, humans cannot make vitamin C.

    The RDA for vitamin C is 75 mgs for females, 90 mgs for males. A suggested supplemental dose is 100 to 2000 mg.

    Specimen collection, preparation and transport is of vital importance for accurate results. Collect the specimen in a cold heparin or EDTA tube. Place tube in ice water and centrifuge immediately. Place 3.0 mL of plasma in 4.5 mL of cold 3% metaphosphoric acid (MPA, supplied with kit). Mix vigorously and freeze. Ship frozen in the MPA tube.

    Vitamin E

    Specimen required is 0.5 mL of serum protected from light and shipped in an amber plastic tube.

    Vitamin E is a fat-soluble vitamin. There are eight forms of vitamin E, however, the most biologically active form is d-alpha-tocopherol. The best defined role for vitamin E is an antioxidant for unsaturated fatty acids in cell membranes. It is also important in energy metabolism and synthesis of RNA, DNA, and red blood cells. It acts as an antioxidant in the lungs against smog. Vitamin E is absorbed in the presence of bile in the small intestine. Deficiency of vitamin E may result in hemolysis of RBCs, sterility, higher risk for heart disease and stroke.

    The RDA is 22 I.U. A suggested supplemental range is 100 to 1000 I.U. A toxic range has not been established, but 4000 I.U. and higher should be taken with caution.

    Vitamin A and Vitamin E may share the same specimen tube. Plasma vitamin C requires special preparation and handling. A tube of heparin or EDTA blood is collected. The sample is centrifuged immediately and 3.0 mL of plasma is added to 4.5 mL of COLD 3 percent metaphosphoric acid.

    Vitamin E is performed on serum. Protect from light and ship in an amber plastic tube.
