Understanding Coral Calcium
Calcium is an essential mineral and is required for human life.
However talk about the benefits of coral calcium can be
confusing and may make it difficult to put into context how we
can benefit from appropriate levels of calcium in the diet, be
it from food or from supplemental sources.
Calcium is the most abundant mineral in the human body, and has
several important functions. More than 99% of total body calcium
is stored in the bones and teeth providing the necessary support
to their structure. As a normal function of biology, the living
cells of the body absorb new calcium to replace lost calcium or
to build upon existing structure as in the case of childhood
growth or in healing.
Coral calcium is a salt derived from fossilized coral reefs. The
living coral reefs are endangered and most major reefs are
protected by law as they cannot be harvested without severe
damage to the ecosystem. Coral calcium is harvested by grinding
up above-ground limestone deposits that were once part of a
coral reef.
Coral calcium itself is composed primarily of calcium carbonate
with small amounts of magnesium and other trace minerals.
Chemically, calcium carbonate from coral sources is no different
than from other sources of calcium, despite the claims otherwise
by some companies. However, the addition of trace minerals,
which may be deficient ones diet, could explain why some claim
benefits of coral calcium over more refined sources of calcium
supplements.
While the calcium component of coral calcium is identical to any
other limestone deposit, fossilized coral reefs may contain
trace minerals helpful to the human body. Though it's unlikely
that a well-fed individual would be deficient in any of these
minerals, clear dietary data shows that while the average
American diet may be providing abundant levels of calories,
salt, fat and preservatives, it is otherwise low in nutrition.
Therefore, many people may benefit from a basic level of
supplementation of all essential and necessary nutrients,
including calcium.
There have been many unsubstantiated claims made regarding coral
calcium, perhaps the most controversial of which is the
suggestion that coral calcium cures cancer by increasing pH of
the body. Scientific studies have been performed indicating that
cancer cells cannot survive at sufficiently high pH levels.
However, while this may be true when tested in a Petri Dish, the
pH required to kill cancer cells also kills healthy human cells.
Another problem with the "body alkalinization" concept is that
the body pH doesn't change, regardless of how much calcium
carbonate is ingested. The human body can only function properly
within a narrow pH range. It has been shown that if alkalinizing
agents are ingested, the body promptly excretes the alkaline
components in urine. Attempting to increase the pH of bodies
only appears to succeed in raising the pH of the urine. The same
applies if acidic foods are ingested in that the urine becomes
more acidic.
Calcium itself is an essential mineral for human life, and coral
calcium is an effective source of it, though by no means the
only one. When researching any supplement, keep in mind that
supplements are intended to improve nutrition. They are not
designed to treat, cure or mitigate any disease. However, high
quality supplements are an excellent way to supplement, but not
substitute, the benefits of a good diet.
