In the late eighteenth century
English sailors carried limes on long voyages to ward off scurvy,
which led to them being given the nickname ‘limeys’.
But it was not until 1932 that ascorbic acid (vitamin C), a
water-soluble white powder, was isolated and identified as the
substance in certain foods responsible for curing scurvy.
What does it do for your body?
Vitamin C is involved in over 300
biological processes in the body.
Collagen - Vitamin C is
necessary for the manufacture of collagen, the protein which forms
the basis of connective tissue. The most abundant tissue in the
body, connective tissue acts as a cementing substance between cells.
It helps support and protect blood vessels, bones, joints, organs
and muscles and forms a sizeable proportion of skin, tendons, the
cornea of the eye, ligaments, cartilage, teeth and bone. Collagen
forms a protective barrier and promotes healing of wounds, fractures
and bruises.
Antioxidant - Vitamin C is the
body’s most powerful water-soluble antioxidant and plays a vital
role in protecting the body against oxidative damage. It neutralizes
potentially harmful reactions in the watery parts of the body such
as the blood and the fluid inside and surrounding cells. It helps
protect LDL cholesterol against free radical damage. This
antioxidant action helps to protect the health of the heart and an
array of other body tissues.
Hormones - Vitamin C is
important in the synthesis of hormones by the adrenal glands.
Cardiovascular System -
Vitamin C plays a role in cholesterol production in the liver and in
the conversion of cholesterol to bile acids for excretion. It
supports normal total blood cholesterol and LDL cholesterol and
raises beneficial HDL cholesterol. Vitamin C also supports normal
circulation, therefore supporting the health of the heart. Vitamin C
also helps control healthy blood pressure.
Nervous System - Vitamin C
plays a role in the conversion of tryptophan to serotonin, a
neurotransmitter with many vital functions.
Absorption: Body tissue stores
of vitamin C are small and easily saturated, with any excess
excreted in two to three hours.
Deficiency: Vitamin C
deficiency is extremely rare. A lack of vitamin C leads eventually
to scurvy. The symptoms are mainly due to poorly formed collagen and
include the breaking open of small blood vessels, the reddening and
bleeding of gums, loose teeth, joint pains, dry scaly skin and blood
vessel damage. Other symptoms include general weakness, fluid
retention, depression, and anemia.
Vitamin C deficiency can lead to slower wound healing, increased
susceptibility to infections, male infertility and increased genetic
damage to sperm cells which may lead to birth defects. It may also
contribute to rheumatoid arthritis and gastrointestinal disorders.
Therapeutic effects: Vitamin C has a number of health effects
Cardiovascular System - Vitamin C may protect the heart by
preventing the oxidation of artery clogging LDL cholesterol. Studies
have shown that high vitamin C intake is linked to heart health.
Vitamin C may also be of benefit in the support of normal high blood
pressure and circulation.
Lungs - There is some evidence that vitamin C may be of
benefit in maintaining the health of the respiratory system. This
effect may be due to the antioxidant effect of vitamin C on
oxidizing agents. Vitamin C may also improve lung and white blood
cell function and decrease respiratory stress.
Immunity - Vitamin C boosts immunity by increasing the
production of B and T cells and other white blood cells, including
those with a critical role in natural defenses. It also increases
interferon levels and antibody responses and has antiviral and
antibacterial effects. These immune-stimulating effects lead to
improved resistance against infections. Though the research is
contradictory and inconclusive, Vitamin C may reduce the duration of
colds and the severity of cold symptoms such as sneezing, coughing
and sniffling by reducing blood levels of histamine, which can
trigger tissue inflammation and runny noses. It may also protect the
immune cells and surrounding tissue from oxidative reactions that
occur when cells fight bacteria.
Cataracts - Many studies show that vitamin C may protect the
health of the eye, possibly by reducing ultra violet damage. Vitamin
C is highly concentrated in the lenses of normal eyes which may
contain 60 times the amount of vitamin C as the blood, while
stressed lenses have levels that are much lower. Vitamin C may act
to protect the lens from oxidative damage and protect enzymes within
the lens that remove oxidation damaged proteins.
Diabetes - Increasing vitamin C intake in diabetics may
support circulation, especially micro-circulation.
Other Benefits - Vitamin C may also protect the skin from sun
damage and improve response to stress, including an improvement in
athletic performance due to the effects on adrenal hormones.
Interactions: Vitamin C helps
in the body’s absorption of iron by helping convert dietary iron
to a soluble form. It is also involved in the conversion of folic
acid to its active state. Vitamin C deficiency may lead to increased
excretion of vitamin B6, and vitamin B-6 deficiency leads to low
levels of vitamin C, as can a deficiency of vitamin A. Vitamin C
protects against the toxic effects of cadmium, copper, vanadium,
cobalt, mercury and selenium. Large doses of vitamin C may lower
vitamin B-12, copper and selenium blood levels. Calcium and
manganese supplements may decrease vitamin C excretion and vitamin C
supplements may increase manganese absorption.
Exposure to cigarette smoke or air pollutants such as ozone and
carbon monoxide may deplete vitamin C in the lungs.
Large doses of vitamin C may interfere with contraceptive pill
absorption and reduce its effectiveness.
Aspirin, alcohol antibiotics and steroids may increase vitamin C
requirements.
Vitamin C may diminish the response to some antidepressants, and the
anticoagulant drug warfarin.
