Natural C 1,000 mg
Natural C 1,000 mg tablets from Douglas Laboratories contain
1000 mg vitamin C with rose hips and an additional amount of bioflavonoid
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. It also participates in the
biosynthesis of carnitine, serotonin, and certain neurotransmitters, including
Vitamin C is among the most powerful antioxidants in humans and
animals. It is a water-soluble, chainbreaking 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
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. Bioflavonoids (also called flavonoids) are a class
of phytochemicals that are potent antioxidants, which scavenge many potentially
damaging free radicals.
Another aspect of the antioxidant properties of bioflavonoids is
their synergy with vitamin C, as well as their ability to bind to metal ions,
preventing these metals from catalyzing enhanced free radical production.
Many bioflavonoids support the health of the body’s circulatory
system by helping maintain capillary blood flow and proper vascular
permeability, integrity, and resiliency.
Natural C 1,000 mg tablets may be a useful dietary supplement
for those who wish to increase their daily intake of this important antioxidant
vitamin together with a bioflavonoid complex.
