It's interesting--if an athlete takes a supplement and
feels better, or performance improves, they assume the
"supplement did all the work". However, proof only comes
when the same result can be duplicated again and again;
but if the athlete thinks this "miraculous" pill caused
positive results it is difficult to convince them
otherwise. The question is: what caused the change--the
supplement itself or the athlete thinking it did?
The manufacturers of most nutritional supplements
will tell you how wonderful their supplement is and how
it will improve athletic performance. If you believe
this, the placebo effect starts and performance may
improve. |

Separate Fact From Fantasy
Good research attempts to separate fact
from fantasy and is done with double-blind
studies where athletes are given either the
actual supplement or a placebo that looks
and tastes like the supplement. Double-blind
means neither the researcher nor the athlete
knows what is being taken until the end of
the study when the special "research code"
is revealed. If those taking the supplement
improve performance and those taking the
placebo don't, the researchers may be onto
something positive. If both groups improve,
it's probably the "placebo" effect or simply
the effects of regular training.
Unfortunately this isn't as easy as it
sounds and researchers can spend years
researching a supplement and still not get
an answer. In the meantime, manufacturers
make claims without fact. But considering
the fact that as little as a one percent
improvement can mean the difference between
winning a Gold Medal and finishing out of
the top 20, it isn't surprising that
athletes will try anything that may improve
performance. |

9 Tips for Evaluating Supplements for
Athletes
- Is there any third-party,
randomized, double-blind, crossover,
peer reviewed, published research on
this supplement? Most supplements
have not been researched with healthy
athletes.
- If there is research, has it been
published in a peer-reviewed, scientific
journal? Most manufacturers rely on
articles written about their product.
However these are not research, they are
simply articles.
- If there is research, is it
relevant to the athlete? Many
supplement manufacturers cite research
that is unrelated to the claims being
made about the product. As an example,
one food bar claims to assist in body
fat loss, yet none of the research
references cited to support its claims
actually demonstrated any weight loss
capabilities.
- If there is a patent on this
supplement, what does it mean? It
means the patent holders usually do most
of the research because they directly
benefit from future sales. You can bet
their research is going to show positive
results. But independent research is
rarely published--guess why? No positive
results.
- Is most of the research from only
one researcher or laboratory? The
true value of a supplement can only be
determined if many researchers from
different laboratories work
independently to evaluate the product
under different conditions.
- Has the research been performed
with athletes in normal training or
competition circumstances? Just
because a product has shown benefits for
people with heart disease or nutritional
deficiency, doesn't mean the same
benefits are true for fit athletes.
- Some research may show positive
benefits from a supplement; is there any
research showing "no effect" or possible
dangerous side effects? If one
research paper shows a positive effect,
but 10 others show no effect, it would
be unprofessional and unethical to
promote the positive results while not
mentioning that most of the
research shows no positive
effect.
- Have other independent
scientists, sports nutritionists, sports
dietitians, sports institutes or sports
medicine groups made positive comments
about this supplement?
- Will you benefit from using this
supplement? Research showing
positive benefit for elite athletes does
not necessarily mean the same results
will occur in the recreational athlete.

We Have Testimonials!
Be aware that many supplement
manufacturers or providers do not like being
asked questions because they won't have
valid answers. They rely on testimonials as
proof. Your decision to use or not use needs
to be an informed one, not one made because
a friend or teammate told you about it.
Frequently the argument for using a
supplement is based on poor logic or none at
all. One example of this would be using
"Royal Jelly" from the Queen Bee because
it's a mixture of pollen and secretions from
the glands of worker bees. This is why she
grows to be twice as large as regular bees
and lives a lot longer. This is great for
the bees but what does this have to do with
humans? Based on this logic we should be
eating antelope since the cheetah is the
fastest land animal and it feeds on
antelope. Or, more plankton for swimmers
because the fastest marine animal is the
killer whale. This logic doesn't make any
sense, but it sells product.
A powerful marketing tool is getting
testimonials from famous athletes. These
athletes oftentimes don't have time to earn
money to pay their expenses because they
spend so many hours training. As a result,
they are willing to try supplements and
endorse them to earn some money. It doesn't
mean their decision to endorse this product
is based on good science. |

Lastly..What's In It?
You can never be sure the supplement
actually contains the ingredients stated.
Even more alarming is that some have
ingredients not declared on the
label. The World Anti-Doping Agency (WADA)
says around 20% of nutritional supplements
have undeclared ingredients that could lead
to a positive doping result. In fact, the
WADA warns: "Most supplement manufacturers
make claims about their products that are
not backed by valid scientific research and
they rarely advise the consumer about
potential adverse side effects. The
supplement industry is a money-making
venture and athletes should get proper help
to distinguish marketing strategies from
reality."
