ASCORBIC ACID (as Sodium Ascorbate)
Description:
Vitamin C, or ascorbic acid (antiscorbutic vitamin), is necessary for the prevention and cure of the deficiency disease scurvy. These points to the relationship of the vitamin in maintenance of tooth structures, matrix of bone and the walls of capillaries. The picture of clinical scurvy in humans is one that can be related to the general breakdown of intercellular collagen substance. Bones become brittle and cease to grow, and normal structures are replaced by connective tissues that contain calcified cartilage. Anemia is common occurrence in scurvy, caused by an impairment of hematopoiesis. Also, vitamin C has been shown to change iron absorption. Keratoconjunctivitis sicca, xerostomia, salivary gland enlargement, xerosis, hyperpigmentation, ichtyosis, neuropathies, and mental depression may occur, even when the full-blown picture of scurvy is absent.
Vitamin C is essential for the healing of bones fractures. Such fractures heal slowly in a patient deficient in vitamin C. Wound-healing is also impaired.
There is evidence to indicate that the vitamin functions in the metabolism of tyrosine.
An intake of 10 to 20mg a day of ascorbic acid is sufficient to protect an adult from classical scurvy, and 45mg a day will maintain an adequate body pool of 1500mg. Smokers likely require an additional 35mg daily. Animal studies testing precursors of known carcinogens showed a reduced number of tumors when the animals where given vitamin C. Biochemical studies suggest that vitamin C blocks the formation of active carcinogens from precursors. Although vitamin C in large amounts may have some pharmacological effects, these are not related to the normal functioning of the vitamin at nutritional levels. Ascorbic acid facilitates the absorption of dietary iron by keeping the iron in the reduced form.
