WHAT
IS CALCIUM AND WHY MIGHT I NEED MORE?
Calcium
is an essential mineral that your body needs every day.
Calcium plays a number of important roles in the body and
if deficient, can cause numerous health issues. First, calcium
is the major constituent of bones and teeth. Over 98% of
body calcium resides in those structures. In the rest of
the body calcium supports heart function, circulation, nerve
function and muscle tone.
If
insufficient calcium results from a poor dietary intake
of this nutrient, the body can "rob" calcium from
the bones to make up the shortage. When this happens, low
peak bone mass can result which is a low amount of bone
mass present at maturity. Low peak bone mass can be a contributing
factor to the development of a potentially crippling disease
of weak, thin and fragile bones called osteoporosis. In
excess of 25 million people in the United States have this
disease which is a multifactorial disease, also affected
by race, sex, heredity, body stature, diet, exercise level,
and life style. Excess alcohol consumption and smoking are
also considered risk factors in osteoporosis.
Building
and maintaining good bone health through adequate calcium
intake throughout life is linked to a reduced risk of osteoporosis
by optimizing bone mass.
Calcium intake exceeding 200% of the recommended daily intake
(2000 mg.) has no further known benefit.
AT WHAT AGE IS CALCIUM INTAKE IMPORTANT?
Very
simply, at all ages. Calcium is important to infant development,
childhood development when bones are growing, during childbearing
and during adulthood to keep bones healthy and strong.
CAN'T I GET ENOUGH CALCIUM FROM MY DIET?
Infant
formulas and some baby foods are rich in calcium as is mother's
milk, so babies and infants probably get enough. Once off
of those sources, getting enough calcium becomes more difficult.
It is generally recognized by the National Academy of Sciences
Institute of Medicine, that from ages four through adulthood,
calcium Dietary Reference Intakes optimum for good health
range from 800 mg. daily to 1200 mg. daily. To get that
from the diet requires an individual to get two to three
servings of dairy products per day plus several servings
of protein, vegetables, grains and fruits. This is difficult
for many people.
Many
individuals are sensitive to dairy products, casein, lactose,
or other dairy proteins. These individuals find it very
challanging to obtain enough dietary calcium.
WHAT AFFECTS CALCIUM ABSORPTION FROM MY DIET?
Fiber-rich
foods and plant foods containing phytic acid can negatively
affect the absorption of calcium as can caffeine. Excess
fat, salt and soft drinks also have a negative effect.
It
is better to spread calcium intakes out over the day as
opposed to taking it all at once. Studies show that when
too much calcium is in the body at once, absorption is diminished.
Vitamin
D increases the absorption of calcium so it is important
to make sure your diet contains sufficient amounts of that
nutrient. Vitamin D is stored in the body so it is not necessary
to consume the vitamin D at the same time as the calcium,
however many calcium supplements contain small amounts of
vitamin D as a precautionary measure. Since milk and cereals
are usually fortified with vitamin D and sunlight also contributes,
older adults without sunlight exposure and with poor diets
are most at risk to be deficient in vitamin D.
WHAT
KIND OF CALCIUM SUPPLEMENT SHOULD I TAKE?
There
are many excellent calcium supplements available on the
market. Calcium Carbonate and Calcium Citrate are the most
popular sources with calcium carbonate being by far the
most abundant. Both calcium carbonate and calcium citrate
are excellent sources and are well absorbed. The New England
Journal of Medicine (1987) reported that these forms of
calcium had similar absorption profiles to the calcium found
in milk and these results have been confirmed in subsequent
studies.
Calcium
carbonate is best absorbed when taken with food. Individuals
with the condition achlorhydria (missing stomach acid) seem
to absorb calcium citrate better, though the difference
is minimized when calcium carbonate is taken with food.
There
is one form of calcium which has shown some advantages in
absorption properties. The form is known as Calcium bis-glycinate
chelate produced by Albion Laboratories Inc. of Clearfield,
Utah. See a discussion of this form of calcium under Kirkman's
Bio-Max calcium product later in this article.
WHAT
OTHER QUALITY ISSUES DO I NEED TO BE CONCERNED ABOUT WHEN
CHOOSING CALCIUM SUPPLEMENTS?
Poor
quality calcium supplements may contain a higher lead content
than is desirable. The United States Pharmacopoeia (USP)
and the Food Chemicals Codex are considered standards for
quality materials used in supplements and the lead tolerance
in these publications is three parts per million (ppm),
an acceptable level to the Food and Drug Administration.
Most reputable companies have adopted these standards. It
can also be pointed out that several high quality pharmaceutical
grades of calcium are also available which have lead levels
far below the 3 ppm accepted standard.
Another
issue in quality calcium supplements is disintegration and
dissolution standards of the dosage form. A product must
dissolve in the body to do any good. Check with your manufacturer
to insure that its calcium products meet USP standards.
Finally,
look carefully at the label of the calcium supplement you
are contemplating buying. The requirements for calcium intake
are referring to elemental calcium. Your supplement should
be supplying the total amount of the mineral calcium, not
an amount of the calcium salt. For example, a supplement
should be supplying 600 mg. of elemental calcium, not 600
mg. of calcium carbonate. If a supplement supplied 600 mg.
of calcium carbonate, it would only be providing 216 mg.
of elemental calcium. If in doubt, call the manufacturer.
Calcium is too important to come up short.
CAN
I TAKE TOO MUCH CALCIUM?
The
National Institute of Health and the Journal of the American
Medical Association seem to agree that calcium can be safely
consumed up to 2000 mg. per day by most people.
