CREATINE CREATES A SENSATION. . .
by ACE
Even If You Don't Know
Exactly what it is, chances
are you’ve probably heard about
creatine. With help from the media and high-profile athletes,
this popular supplement exploded onto the scene several
years ago as news spread of its potential as a muscle builder
and sports-performance enhancer. Further proof of its popularity:
Sales of creatine have skyrocketed from $30 million in
1995 to a projected $180 million in 1998.
Perhaps the greatest testament to creatine’s effectiveness
and, hence, its popularity is the fact that so many who
use it — professional and amateur athletes alike — actually
see results. Fast results. Unlike predecessors such as
chromium picolinate,
creatine has, from the outset, consistently demonstrated
its usefulness in a variety of applications in numerous
scientific studies. More than 50 studies examining creatine
have been published and another 50 are expected to be published
before year’s end.
But neither its popularity nor reports of its effectiveness
have completely erased the doubt and fears of those who
question the safety of creatine supplementation. A recent
survey of the Association of Professional Team Physicians
indicated 85 percent would not recommend creatine until
more research was completed. And, because no study of creatine
has lasted longer than 51 days, it is impossible to know
its long-term effects.
Who’s it for?
Each
of us has varying levels of creatine stored in our
muscles depending on our diets, activity levels and
genetics. Those who appear to benefit most from creatine
supplementation are those with the lowest amounts to
begin with. After the initial recommended loading phase
of 20 to 25 grams per day for five to seven days, the
muscles become saturated with creatine and additional
supplementation beyond a 3- to 5-gram maintenance dose
becomes a wasted — and expensive — enterprise. In fact,
the daily turnover rate for creatine is only about
2 grams per day, making large doses not only unnecessary,
but potentially harmful since protocols deviating from
the recommended dosages have yet to be studied. The
sports performance benefits of creatine are limited
to activities requiring short, all-out bursts of power,
such as:
•
jumping • swimming • sprinting • high-intensity weightlifting
A
recent statement by the American College of Sports
Medicine notes that “creatine supplementation has not
been shown to improve longer-duration aerobic-type
exercise.”
The “More is Better” Syndrome
The controversy
that continues to hound creatine stems from the fact
that the controlled setting of a lab does not always
reflect real life. In a if-a-little-is-goodmore- is-better
society like ours, it’s no surprise that many people
are taking far more than the recommended dosage of creatine,
which is something the researchers have yet to examine.
And few studies have been able to demonstrate creatine’s
effectiveness beyond the lab setting — on a baseball
field, for example, or at a track meet. “Much remains
unknown about whether creatine is absolutely safe for
long-term use at levels currently
being recommended,” said the Food and Drug Administration
in a June 1998 statement cautioning consumers about the
popular supplement. The FDA urges both current and potential
users to see their doctors to identify any potential
health problems. Creatine supplementation is not for
everyone, particularly those with a history of kidney
problems, or who are younger than age 18 or are still
developing. Nor should one expect the supplement to be
effective without a well-designed training program. Every
person should examine their own motives for taking creatine
and weigh it against the potential unknown risks of long-term
usage. But be sure to take the FDA’s advice and
check with your
physician and don’t exceed the recommended dose.
