Minerals
are inorganic elements that come from the soil and water and are absorbed
by plants or eaten by animals. A wide range of minerals is essential
for human health.
Your body needs larger amounts of some
minerals, such as calcium, phosphorus, and magnesium. Other minerals
like chromium, copper, iodine, iron, manganese, molybdenum, selenium
and zinc are called trace minerals because you only need very small amounts
of them each day, yet they have been identified
to have important, if not essential, roles in maintaining health.
There is evidence that the need for mineral intake is not being
met, especially in certain subpopulations. It is difficult for most individuals
to ingest enough calcium from foods available in a cereal-based economy
without liberal consumption of dairy products. Thus, supplementation
with minerals is recommended to complement dietary intake and avoid deficiencies.
Not All Mineral Supplements Are Created Equal
Mineral supplements are associated with different absorptive capacities.
The absorption of minerals depends on a number of physiological, biochemical
and hormonal characteristics of the body and the form of the mineral
consumed. Potential mineral sources are not all alike and should be evaluated
for bioavailability.
Factors That Enhance Mineral Absorption:
Factors that enhance mineral absorption include the form of the mineral
ingested, maintenance of chemical stability, presence of a specific
transporter, small particle size, solubility, ascorbic acid, and low
intestinal motility.
Factors The Inhibit Mineral Absorption: Factors that inhibit
absorption include oxalic acid, phytic acid, (5) fiber(6), sodium, tannins(7),
caffeine, protein, fat, antacids, rapid transit time, malabsorption syndromes,
precipitation by alkalinization, other minerals(8), hormones and nutritional
status(9).
Colloidal minerals exhibit properties that enhance absorption. Principles
of biochemistry support the view that colloidal minerals may be more
bioavailable than minerals in solid supplement or food forms. However,
the vast majority of colloidal mineral supplements on the market today
consist of metallic mineral colloids. Some manufactures contend that
the small size makes it possible for the colloidal mineral to pass through
the membrane of a cell wall. While this may be the case, the metal is
still a metal mineral which has not been chelated. Hence, colloidal minerals
are not organic and are not bio-available. In our view non-chelated colloidal
minerals are not as safe as the naturally chelated minerals found in
MorningStar mineral supplements. This is because colloidal minerals are
metals and may remain in the body until a potentially harmful concentration
has been reached.
What Are Health Benefits of Minerals?
Some minerals are so essential that our body suffers without them. For
example, calcium is needed so that you can grow as tall as you were meant
to grow, to keep your bones and teeth strong, and to keep your muscles
and nerves working smoothly. Phosphorus acts with calcium to give bones
and teeth strength and hardness. Iron is needed for the red blood cells
to carry oxygen. Zinc is needed for the normal growth and repair of your
body's cells.
A number of diseases are associated with mineral deficiencies
or impaired metabolism of minerals (click
here for a partial list). Supplementation
with minerals has improved the nutritional status and lowered disease
risk and progression factors among patients with various disorders. However,
it is important to note that there
is a natural synergy to the minerals in your body, each working in concert
with other minerals to maintain a healthful balance in your body. An
excess of one mineral depletes or diminishes the effectiveness of other
minerals. (See the mineral wheel image to the right.) The ideal is
to find the perfect balance, which is easiest to achieve when taking
supplements that are food based, which already contains nature's perfect
balance of minerals. For instance, some excellent sources of calcium
include coral calcium, which is a whole organism that contains all
the minerals in a form similar to our skeletal system, and
Hydrilla,
a seaweed rich in calcium and other minerals.
