See information on Selenium that
shows we may already have sufficient Zinc in our body and
it is blocked. Selenium will unblock Zinc in our body, thus
we may naturally have enough zinc and need to take selenium
to asimulate it.
Most say there is no known diseases related to zinc
deficiency and there is no way to test zinc levels in the
1. Quote from Micronutrient
Malnutrition "Zinc is essential for
survival and deficiency has serious consequences for health.
Randomized controlled trials showed that zinc supplementation
can reduce the severity of morbidity from a number of common
childhood infections, including diarrhea, pneumonia, and
possibly malaria, by one-third (Bhutta et al. 1999, 2000;
Black 1998; Roy et al. 1999; Shankar et al. 2000). In addition,
zinc deficiency causes stunting (Brown and Wuehler 2000;
Roy et al. 1999; Umeta et al. 2000). Because of inadequate
intakes, billions of people are at risk for zinc deficiency,
but no estimates are available for the number of people
who are zinc deficient as a standard method for measuring
zinc deficiency is not yet available. Micronutrient
2. Quote from Zinc
Facts. "Zinc is essential to life. Every cell requires
zinc to multiply. Your body requires zinc to make white
blood cells. Zinc is essential for healthy skin. It is a
natural element found in every cell of your body, in the
earth, in the food you eat and in products everywhere."
- Zinc is at the forefront of health research. Zinc is
vital during pregnancy. It is essential for the developing
fetus where cells are rapidly dividing.
- Zinc oxide has been used for years to soothe diaper
rash and relieve itching.
- Zinc stimulates the transport of Vitamin A from the
liver to the skin.
- A zinc deficiency is implicated in deteriorating vision
that accompanies the aging process. Zinc boosts brain
- The best source of zinc is lean red meats and seafoods,
- Zinc gluconate lozenges taken at the first sign of a
cold reduces duration and symptom severity by 42%. Insufficient
zinc has been linked to anorexia, which responds well
to zinc replacement treatment. Zinc abnormalities also
often exist in mood disorder patients. Zinc is a vital
nutrient. It stimulates growth, fights infection and heals
3. Quote from Office
of Dietary Suppliments
"Zinc, infections, and wound healing
The immune system is adversely affected by even moderate
degrees of zinc deficiency. Severe zinc deficiency depresses
immune function (27). Zinc is required for the development
and activation of T-lymphocytes, a kind of white blood cell
that helps fight infection (2, 28). When zinc supplements
are given to individuals with low zinc levels, the numbers
of T-cell lymphocytes circulating in the blood increase
and the ability of lymphocytes to fight infection improves."
They also state zinc can lower the incidence of the common
cold. "What is the health risk of
too much zinc? Zinc toxicity has been seen in both acute
and chronic forms. Intakes of 150 to 450 mg of zinc per
day have been associated with low copper status, altered
iron function, reduced immune function, and reduced levels
of high-density lipoproteins (the good cholesterol) (34).
One case report cited severe nausea and vomiting within
30 minutes after the person ingested four grams of zinc
gluconate (570 mg elemental zinc) (35)." Office

3. Zinc is registered
with ATSDR Agency for Toxic Substances and they list a number
of enviromental causes for high levels of zinc and some
adverse affects of zinc in the human body. "Exposure
to large amounts of zinc can be harmful. It can cause stomach
cramps, anemia, and changes in cholesterol levels."

Link "How much do we need? The Recommended
Dietary Allowance (RDA) is the average daily dietary intake
level that is sufficient to meet the nutrient requirements
of nearly all (97 - 98%) individuals in a given life-stage
and gender group. The 1989 RDAs for zinc in milligrams (mg),
are: 15 mg for adult men and 12 mg for adult women; 15 mg
during pregnancy; 19 mg for the first six months of breast
feeding and 16 mg during the second six months of nursing
a baby. " Health
5. A 7-day
reduction in duration of common colds was shown
by Eby et al. in 1984 using 23mg zinc gluconate throat lozenges.
The recommended upper limit for zinc intake is 40 mg/day.
Toxicity is rare. Ingesting doses of elemental zinc ranging
from 100 to 150 mg/day for prolonged periods interferes
with copper metabolism and causes low blood copper levels,
RBC microcytosis, neutropenia, and impaired immunity; higher
doses should only be given for short periods of time and
the patient followed closely. Ingesting larger amounts (200
to 800 mg/day), usually by consuming acidic food or drink
from a galvanized (zinc-coated) container, can cause anorexia,
vomiting, and diarrhea. Metal fume fever, also called brass-founders'
ague or zinc shakes, is caused by inhaling industrial zinc
oxide fumes; it results in neurologic damage. Symptoms usually
resolve after 12 to 24 h in a zinc-free environment."
