Real World Fat Loss Diet & Weight Loss Supplement Review
What I am about to tell you is
not going to make me a very popular person with many supplement manufacturers.
In fact, some of them are going to be down right pissed off at me. On the other
hand, some of them are going to be happy someone spilled the beans and told the
truth. Finally, some of them will be totally unaware of this information and
will be shocked when they read it. Basically, I fully expect this article to
cause a sh*% storm that will reverberate throughout the supplement industry.
The only people who I know are
going to be happy about this article is the consumer, but I am getting ahead of
myself. As we all know, creatine is one of the best bodybuilding supplements
ever discovered. It increases strength, lean body mass, and, to a lesser extent,
endurance. If that were not enough, it's relatively cheap to boot! What more
could we ask for from a supplement? When creatine was first introduced it was
sort of pricey, but no one really cared because it worked so well. As time went
on and more companies began selling creatine, the inevitable price war began and
prices came down.
At that point creatine was only
being produced by a few companies, so creatine was basically creatine and the
price was the only real consideration. As is typical of the market place, once
creatine became big business, several new manufacturers popped up and it became
no longer a price war as much as a quality war. The expression "creatine is
creatine" no longer holds true. More on that shortly.
At this time there are probably
four-five companies large enough to mass produce creatine for the sports
nutrition market. These companies in turn sell their product in huge bulk
amounts to various distributors around the world. As far as the mass producers
are concerned, there is a large German company, two companies out of China, and
two in the United States. Though there are various other companies, for this
article we will basically concern ourselves with these five major producers
which probably comprise 80-90% of the creatine production market.
Why I had to write this
article
The supplement industry in the
United States is by and large a self-regulated industry. Unlike other countries,
we (the USA) don't have government constantly telling us what we can and cannot
do with our supplements. Though they have been trying to discredit supplements
for decades, the FDA and pharmaceutical/ medical industrial complex have largely
failed to do so. As a self-regulated industry, we must do just that. Let me
state here and now, I am all for self-regulation and totally against government
regulation when it comes to supplements. When we find gross problems, we have to
expose them no matter what the cost. Any supplement that is found to be
potentially dangerous, terribly misleading, or otherwise a total scam, must be
exposed as such.
If we don't do it, then we
allow the "powers that be" (who have an interest in discrediting the supplement
industry) to get one step closer to the Orwellian scenario of other countries. I
thought long and hard as to whether or not I should write this article, but in
the end, as a person of good conscience and ethics, I knew I had to. In the end,
it will cost the entire supplement industry far more than any one loss could
ever cost a single company if problems with a certain product are not exposed.
As far as I am concerned, this
is us airing out or own dirty inter-industry laundry and policing our own,
instead of waiting for the "don't confuse us with the facts" popular media or
other groups to come after the supplement industry. I know it must sound like I
am almost apologizing for writing this article, and in a way I am. It could
potentially cost certain people a great deal of money. On the other hand, it
could also make some other person a great deal of money, depending on where they
fall (this will make more sense to the reader as you read along). In the end,
the truth can never been denied, it can only be delayed. With each day of delay,
the cost to everyone goes up. Nuff said.
Are you getting more than
you paid for?
Most of us are always happy
when we get more than we paid for, but in some instances, it's not such a good
idea. If we are buying say vitamin C and the label says "500mg per capsule" and
laboratory analysis reveals it contains 600mg, then that is a great thing.
However, if we test a product and not only does it contain what the label
claims, but several other compounds we did not know were in there and had no
place being in there, then that's a completely different story. For example,
when the amino acid L-Tryptophan was taken off the market for the death of
several people, it was not because of the L-Tryptophan itself, but because of a
chemical contaminant found in a batch of the L-tryptophan that was not supposed
to be there. This was a perfect example of getting more than you paid for in the
worst possible scenario. What I am going to write about in this article
certainly is not as bad as the L-tryptophan fiasco, but it could be a potential
health concern.
So after that long, cryptic,
and bizarre introduction, what am I getting at? Recently, a company tested the
five largest creatine manufacturers products and tested the products of various
distributors from the USA, Germany, Great Britain, and other countries. At this
time, the company who did the testing wishes to remain anonymous, lest they be
accused of throwing stones at the supplement industry. However, this is a very
large and reputable company and they stand behind their test results.
Also, I know this company to be
one of the worlds most reputable companies, so I had no problems with their
testing results or methods. The test results came to me through the back door so
to speak. So what was tested for and what did it reveal? The creatine products
were tested for: Dicyandiamide, Creatinine, Dihydrotriazine, and sodium content.
What did the tests reveal? It revealed that there is a wide range of differences
between creatine products from different manufacturers. The purity level of all
the creatine products were also tested and they generally fell between 88 and
92%. Now before you go off yelling "but my creatine says 99% pure creatine
monohydrate on the bottle," you have to remember there is a small amount of
water in creatine monohydrate.
Before we bother with the
results, we need to take a look at the chemicals that were tested for-and
subsequently found- in these samples. What really bothered me was the fact that
there is little safety research on some of these chemicals, most notably the
dihydrotriazine. I did Med-line searches, looked through various chemical data
related books (i.e. the Merck Index and other publications), made many phone
calls to chemists, spent hours on the internet, and was amazed to find so little
real safety data on some of these materials.
Considering the fact that some
creatine products contain fairly high amounts of these chemicals, the lack of
solid safety data did not make me feel very comfortable. The major point of this
is really the amount of creatine ingested in relation to the amount of
contaminant present. It's not that a compound has a small amount of some
contaminant per se, but the levels of the contaminant is found in relation to
how much of the product is consumed is the real question. In the December issue
of Health and Nutrition Breakthroughs (p12, 1997) Dr. Podell addressed the same
concern regarding creatine as I have when he stated "...there is the potentially
important issue of product purity. Given the high doses of creatine most people
take, even a minute toxic impurity could have a dangerous effect. Unfortunately
we cannot be sure of a manufacturers' quality controls."
As we all know, people don't
just take 500mg (1/2 a gram) of creatine, they take 10,000mg (10g), 20,000mg
(20g), or even 30,000mg (30g) of creatine per day, so even a small amount of a
contaminant (such as the dihydrotriazine) can add up quickly. For example, one
creatine product contained as much as 18,000 parts per million (PPM) of
Dicyandiamide. If a person is taking in ten grams per day of creatine, that's
180 mg of this chemical a day. If you are taking in 30g a day of creatine-as is
often the case during the loading phase-you would be getting a whopping 540mg a
day of dicyandiamide!
The Chemicals
Dicyandiamide (DC): DC
is actually a derivative of one of the starting chemicals (cyanamide) used in
creatine production. DC is formed during the production of creatine products,
and large amounts found in a product are considered the result of an incomplete
or inefficient process. A quality creatine product will contain very small
amounts, less than 20-50ppm. At this time, DC does not appear to be a
particularly toxic chemical. Oral studies with animals (rats and dogs) lasting
up to 90 days have not shown serious toxicity or carcinogenic effects, and acute
poisoning also takes very high amounts. DC appears to have many uses in the
chemical industry. Some of the more interesting is the use of DC in the
production of fertilizers, explosives, fire proofing compounds, cleaning
compounds, soldering compounds, stabilizer in detergents, modifier for starch
products, and a catalyst for epoxy resins.
At the concentrations found in
some of the creatine products (see below), it's a good thing this stuff does not
appear to be particularly toxic. However, as far as I am concerned, I don't want
to be eating the stuff. One interesting point as it relates to DC and toxicity
is, if one looks at the safety sheet on the stuff it states that DC breaks down
into hydrogen cyanide gas when exposed to a strong acid. Hydrogen cyanide gas is
very toxic and has been used as a chemical warfare agent! As Bruce Kneller
points out (see side bar), stomach acid, which has a PH of 2, is a very strong
acid. Is even a tiny amount of hydrogen cyanide gas produced from the intake of
large amounts of DC? The chemist I spoke to did not seem to think so and the
safety data with animals would tend to support this, but who knows. Bruce might
be overreacting a bit on this, but it's better to lean on the cautious side with
such things. Bottom line, it's best not to be eating large amounts of DC in this
writer's opinion.
Dihydrotriazine (DT): DT
appears to be the real mystery chemical as far as potentially toxic contaminants
found in some creatine products. One company had it listed as "...Dihydrotriazine
is often found in various creatine products. This substance is a byproduct of
non-optimized creatine productions and consequently widely spread over creatine
products. Dihydrotriazine is a compound with unknown pharmaceutical and
toxicological properties." It was virtually impossible to find any useful safety
data on this chemical.
However, DT is part of a large
family of chemicals known as the "triazines." It is an organic base with many
derivatives. Some of these derivatives are toxic while others are known to be
non-toxic, so it is very difficult to come to any real solid opinion regarding
the potential toxicity of this chemical. One chemist I spoke to from a major
pharmaceutical supply company said to me on the phone "it's safe to say that
there will be major differences in toxicity between derivatives since 'triazine'
simply means possessing three C=N-H groups. Some derivatives are highly toxic."
Bill Roberts, a medicinal
Chemist and writer for Dan Duchaine's Dirty Dieting news letter commented after
I sent him over this information: "There really is no way to say just how high a
chronic intake of this chemical [these chemicals] is safe in humans from the
information given. If the amounts were very small, say a few milligrams per
week, it's a reasonable guess that there would probably be no problem.
But if a creatine brand has say
1% of this impurity [these impurities] then people are going to be consuming
thousands of milligrams of this compound [these compounds] over time. I think we
have to be concerned about taking so much of something that really isn't well
studied in humans for safety. It would certainly be unwise to assume
thattoxicity is not an issue. If the consumer has a choice between a creatine
brand that contains this impurity [these impurities] in significant amounts, and
one that is more pure, I'd certainly recommend spending the extra money and
obtaining the purer product."
So as you can see, we are left
with a major question mark regarding DT. For me, the less I know about a
chemical the less of it I want to find in any product I am ingesting. Though
this chemical might turn out to be perfectly harmless, I think it should not be
found in any amount and thus should be non-detectable (n.d.) in the ppm range
until we know more about this chemical. As you can see from the tests, some
companies have n.d. amounts while others have far more than that. I find this
unacceptable, and so should you.
Creatinine: Creatinine
is one of the easy compounds to discuss on this list. Creatinine is actually a
natural byproduct of creatine metabolism in the human body and of creatine
production. A small amount can be found in every creatine product. However, in
some products large amounts can be found, as high as 7700 ppm in one case (see
chart). It is probably safe to say that the ingestion of creatinine is a safe
endeavor. There is some research that links the ingestion of creatinine from
meats with increased colon cancer incidence, but in all honesty I would not put
much stock in that or get all worked up about it . The point is, when I buy
creatine I want to eat creatine, not creatinine. Though a natural byproduct of
creatine metabolism, it does not have any ergogenic effects and therefore I
don't want large amounts of it in my creatine, period. A high quality creatine
product should contain less than 100ppm of creatinine in my opinion.
Sodium: Like the
aforementioned creatinine, sodium is an easy one to talk about. Also, like
creatinine, it is a generally safe thing to ingest at normal intakes. At the
levels found in these creatine products, the amount of sodium added to the diet
is very small and should pose no problems, even to the most sodium phobic
person. However, like I said before, when I pay for creatine I want creatine,
not sodium. The lowest sodium content was 20ppm and the highest was 500ppm. I
leave it to the reader to decide what is a tolerable sodium content to them.
Conclusion
Believe it or not, the company
who did the testing told me that although those were the main chemicals they
tested for, some creatine products read like a who's who of different chemical
compounds, though they admitted that they are usually found in trace amounts. As
for the consumer, if it were me, I would demand the HPLC test results from whom
ever I was buying my creatine from regarding the chemicals listed in this
article. If you don't care, that's OK also. As for me, I will make sure my
creatine comes only from companies and distributors who sell creatine made by
the large German company, or other companies, who clearly have their collective
act together when it comes to producing an ultra pure creatine product. Bottom
line? The expression "creatine is creatine" no longer holds true. However, a
high quality creatine product it still the best thing going in
bodybuilding/sports supplements.
