Vitamin C is a water-soluble vitamin
that must be consumed daily as it is not synthesized within
the human body. Vitamin C is known for its superior
antioxidant effects, which comes from its ability to remove
the hydroxyl free radical, which is considered to be the most
reactive and damaging free radical species.
Adequate ascorbic acid intake is necessary for good immune function,
the maintenance of bones, the formation of collagen and a broad
range of more than 300 bodily functions. Bioflavonoids work
together with vitamin C to help build strong capillaries and
serve as antioxidants and as natural anti-inflammatory agents.
Unfortunately, human beings, unlike most other animals, cannot
manufacture vitamin C nor can they store vitamin C to any appreciable
amount. The kidneys,
acting as regulators, readily excrete vitamin C and cause the
need for daily replenishment. In addition, vitamin C is easily
destroyed during food preparation.
Cigarette smoking and excessive alcohol consumption is associated
with a significant decrease in vitamin C levels, and such users
would be well advised to supplement their diet with several
times the RDA of vitamin C.
Vitamin C's primary function is to help maintain collagen, a
protein necessary in the formation of the skin, ligaments, bones
and teeth and to help maintain the strength of blood
vessel walls. Bone density and vitamin C status begins to
decline after the age of 35. High levels of vitamin C are also
essential for the metabolism of white blood cells, which are
critical components of the immune
system. In addition, vitamin C plays an important role in
the absorption
of iron, which is necessary for the formation of red blood
cells and in the utilization of folic acid, one of the B-complex
vitamins.

80 to 90 mg
The amount of vitamins and minerals as set by the RDA only provides
us with the bare minimum required to ward off common vitamin
deficiency diseases such as beriberi, rickets, scurvy and night
blindness. Water soluble vitamins, such as vitamin C, B and
folic acid, must be replenished daily and have been shown to
exhibit numerous positive health effects when taken in amounts
that are greater than the recommended daily allowance.
Vitamin C supplementation is extremely safe, with daily doses
as high as 5,000 mg per day shown to exhibit no harmful side
effects. Some individuals can experience diarrhea with daily
doses of 2,000 mg or more.
- If you are pregnant or nursing do not take any form of vitamin
supplement unless you have discussed its use with your doctor.
