This
essential mineral is important for the growth and health of the
reproductive organs and in the function of the prostate gland in
males.
Zinc
may help prevent acne and regulate the activity of oil glands. It
is required for protein synthesis and collagen formation, and promotes
a healthy immune system and the healing of wounds. Zinc also allows
activity of taste and smell. It protects the liver form chemical
damage and is vital for bone formation. It
is a constituent of insulin and many vital enzymes,
including the antioxidant enzyme superoxide dismutase (SOD). It
also helps to fight and prevent the formation of free radicals in
other ways. Organic zinc has been found to have antioxidant activity
comparable to that of vitamin C, vitamin E, and beta carotene; and
are effective in relieving symptoms of the common cold and reducing
the duration of colds.
Sufficient
intake and absorption of zinc are needed to maintain the proper
comentration of vitamin E in the blood. In addition, zinc increases
the absorption of vitamin A. For optimum health, a proper balance
between copper and zinc levels should be maintained.
A
deficiency of zinc may result in the loss of senses of taste and
smell. It can also cause fingernails to become thin, peel, and develop
white spots. Other possible signs of zinc deficiency include acne,
delayed sexual maturation, fatigue, growth impairment, hair loss,
high cholesterol levels, impaired night vision, impotence, increased
susceptibility to infection, ingertility, memory impairment, a propensity
to diabetes, prostate trouble, recurrent colds and flu, skin lesions,
and slow wound healing.
Comments
Zinc
levels may be lowered by diarrhea, kidney disease, cirrhosis of
liver, diabetes, or the consumption of fiber, which causes zinc
to be excreted through the intestinal tract. A significant amount
of zinc is lost through perspiration. The consumption of hard water
also can upset zinc levels. Compounds called phytates that are found
in grains and legumes bind with zinc so that it cannot be absorbed.
If you take both zinc and iron supplements, take them at different
times. If these two minerals are taken together, they interfere
with other’s activity.
Caution
Do not take a total of more than 100 milligrams of "elemental"
zinc daily. While daily doses under 100 milligrams enhance the immune
response, doses of more that 100 milligrams can depress the immune
system.
