Vitamin C, provided by Douglas Laboratories,
contains 1000 mg of 100% pure, corn-free vitamin
C (L-ascorbic acid) per tablet.
Vitamin C (ascorbic acid) has numerous biological
functions. Foremost, it is essential for the
synthesis of collagen and glycosaminoglycans
which are the building materials of all connective
tissues, such as skin, blood vessels, tendons, joint
cartilage and bone. Vitamin C is the required
coenzyme for two groups of enzymes that catalyze
the crosslinking of collagen fibers-lysyl
hydroxylases and prolyl hydroxylases. As such,
vitamin C is essential for normal wound healing
and capillary health.
Vitamin C participates in the biosynthesis of
carnitine, serotonin, and certain neurotransmitters,
including norepinephrine.
Vitamin C is among the most powerful antioxidants
in humans and animals. It is a water-soluble,
chain-breaking antioxidant that reacts directly with
superoxide, hydroxyl radicals, and singlet oxygen.
Laboratory studies show that vitamin C completely
protects lipids in plasma and low-density
lipoprotein (LDL) against atherogenic peroxidative
damage. In addition, vitamin C interacts with
glutathione and alpha-lipoic acid, and regenerates
vitamin E.
The antioxidant functions of vitamin C appear to
have clinical significance in providing protection
from free radical damage to the eyes, lungs, blood
and the immune system.
Vitamin C is absorbed in the small intestine by a
sodium-dependent transport process that is intake
dependent. At normal dietary intakes of 60 to 100
mg, up to 80 or 90% of the vitamin C is absorbed.
At higher intakes, absorption becomes less
efficient. Absorption efficiency and vitamin C
utilization may be greatly enhanced during
conditions of physiological stress, such as trauma
or infection. Maximal absorption is attained by the
ingestion of several doses spaced throughout the
day rather than in one, larger dose.
