CREATINE Frequently Asked Questions
How much CREATINE does muscle store? The
average human has between 3.5 and 4 grams of CREATINE per kilogram of muscle.
Once you use up the CREATINE in your muscle you have to rest your muscles and
wait a while before you can exercise the muscle again. Studies have shown that
the human muscle can store up to 5 grams of CREATINE per kilogram.
What happens to CREATINE that is not used by the body? Excess CREATINE is
eventually converted into the waste product creatinine and excreted from the
body.
How much CREATINE do we have in our body? This varies based on the amount of
muscle mass you have and your weight. On average a 160 pound person would have
about 120 grams of CREATINE stored in their body.
Where is CREATINE stored in our body? It is believed that 95 - 98% of the
CREATINE in our body is stored in our muscles. The remaining 2 - 5% is stored in
various other parts of the body including the brain, heart and testes.
CREATINE is a natural component of skeletal
muscle. CREATINE was identified as an indispensable part of skeletal muscle in
1835 by a French scientist and philosopher , Michel-Eugène Chevreul, who
isolated a component from skeletal muscle which he called CREATINE after the
Greek word for flesh, or Kreas. By 1847 a German scientist ,Justus von Liebig ,
proposed that CREATINE is necessary to support muscular activity when he
observed that wild foxes had more intramuscular CREATINE than foxes kept in
captivity.
Meat and fish are the richest natural sources of CREATINE. Carnivores receive
their CREATINE directly via dietary channels. Herbivores and vegetarians are
solely reliant on their body's natural ability to synthesis CREATINE from basic
components. In this respect we always recommend CREATINE to any Vegetarian
Athletes who is looking to increase or enhance their performance levels -
typically we would recommend
CREATINE Ethyl
Ester.
When dietary CREATINE
intake is restricted (or entirely absent) the body can produce CREATINE from
amino acids made available during the digestion of foods .The production of
new CREATINE mainly takes place in the liver Kidneys and the pancreas . CREATINE
is produced in a chemical reaction involving three amino acids, glycine ,
arginine and methionine. Of these methionine is most critical,
since the body does not readily produce it from starting materials .Most of the
body's entire CREATINE reserve (95%) is found within skeletal muscle. The
remainder is mainly found within the heart, brain and testes, are all tissues
with extremely high energy expenditures. After ingestion CREATINE is transported
to the muscles where it increases muscle energy levels. CREATINE achieves this
by increasing the availability of ATP, the cell's energy molecule . Research has
shown that most people notice an improvement in exercise performance when our
muscle CREATINE levels increase by at least 20% as a result of CREATINE
supplementation .
CREATINE enhances physical performance by increasing the number of times that
ATP can be recycled during physical exertion without increasing the absolute
amount of ATP stored within our muscles. In the short-term this means that
CREATINE supplementation should improve your ability to sustain near maximal
force generation during repetitive bouts of intense exercise without actually
increasing the amount of peak force we can produce.
In one form or another, CREATINE is obtained from the foods we eat , unless of
course you are a vegetarian. 2-3 pounds of raw meat or fish contain the
equivalent
of 5 grams of pure
CREATINE monohydrate
powder . Since heat degrades CREATINE, however, cooking will reduce the
CREATINE content of these foods and increases the amount you'll need to eat to
obtain a given amount of CREATINE.
CREATINE SYNTHESIS: When dietary CREATINE intake doesn't meet the body's needs,
new CREATINE can also be synthesized from the three amino acids; arginine,
glycine and methionine, made available during the digestion of foods.
Importantly, methionine availability sets an upper limit on CREATINE synthesis,
since the body can not produce it on its own. Methionine is thus classified as
an essential amino acid and, in this capacity, provides us with our principal
source of exogenous methyl groups to support growth and development. In essence, methylation maintains life! It is thus imperative that methionine be present in
our diets to assure that these indispensable cellular processes continue
unabated.
Interestingly, methionine is also one of the amino acids used in the synthesis
of CREATINE. CREATINE supplementation under certain circumstances stimulates
anabolic hormone release, reduced blood cholesterol levels, reduced protein
degradation following intense exercise . CREATINE promotes muscle anabolism via
two principal pathways: (1) CREATINE supplementation increases muscle's
immediate energy reserves (ATP and PCr), thereby increasing exercise output; (2)
CREATINE supplementation augments cellular methylation capacity, thereby
creating a more favorable metabolic environment to support muscle anabolism. It
is my opinion that taking full advantage of CREATINE's ability to enhance
cellular methylation will be the next big wave in CREATINE optimization.
Not
all muscle types respond equally to CREATINE supplementation. Muscles can be
loosely described as either fast or slow. As the name implies, fast muscle
fibres mediate abrupt movements. Fast muscle fibers are also those that
predominantly use CREATINE energy production. Hence, explosive movements respond
best to CREATINE supplementation. Slow muscle fibers, on the other hand,
do not rely that heavily on CREATINE energy production. Slow muscle fibers are
also those that play an important role during endurance exercise. It follows
that endurance tasks are influenced less by CREATINE supplementation. In
addition, many endurance sports may be adversely effected by the increase in
weight associated with CREATINE supplementation .
Not everyone responds to CREATINE supplementation. It is estimated that between
20-30% of the population will not respond to CREATINE supplementation. Typically
we have found that non-responders become responders by switching from
Monohydrate to either Ethyl Ester or
Kre-Alkalyn CREATINE - this is just our own experience and as far as we know
there is no science to back this up other than the science behind CEE and
Kre-Alkalyn which shows, in simple terms, that they are far more potent and
efficient ways of taking CREATINE rather than basic Monohydrate Powder.
So what does CREATINE do?
1. Provide additional energy for your muscles - In your body you have a
compound called ATP (adenosine tri-phosphate).
Adenosine Triphosphate (ATP) is the primary energy source found in all living
things. ATP fuels most cell activities, including muscle movement, protein
synthesis, cell division, and nerve signal transmission. In this computer
graphic representation of an ATP molecule, the three phosphate groups are shown
in orange. ATP's chemical energy is stored in its phosphate bonds.
2. Cellular Hydration of your muscles - This is the process of pulling fluid
into the muscle cells and thus increasing the volume of the muscles. CREATINE
has been shown to pull water into your muscle cells, which increases the size of
your muscles.
3. Buffer Lactic Acid build-up -New research has shown that CREATINE can help
buffer lactic acid that builds-up in the muscles during exercise. This leads to
that nasty burning feel you get in your muscles. Scientifically it is a
complicated process - basically the CREATINE bonds with a Hydrogen ion and that
helps delay the build up of lactic acid.
4. Enhances Protein Synthesis - There is some data to indicate that CREATINE
helps put the body in a more anabolic state where protein synthesis can occur.
The more protein synthesis - the greater the muscle gain.
Depending upon your Preferences we would
recommend that for the optimum CREATINE Supplement you either buy
CEE CREATINE Ethyl Ester or
Kre-Alkalyn CREATINE OR if you are a HARDCORE
BODYBUILDER then CryoShock or
Voluplex would be the best solution for you. You will though see Creatine
listed on supplement packs as any of the following:
Creatine Anhydrous
Creatine Citrate
Creatine Malate
DiCreatine Malate 2CM
Creatine Monohydrate
Creatine Phosphate
Creatine Pyruvate
Creatine Tartrate
Creatine Titrate
Magnesium Creatine
Micronised Creatine
Monocreatine-Malate
Effervescent Creatine
Liquid Creatine
Creatine Serum
CEM3 (creatine ethyl ester malate)
CEE (creatine ethyl ester HCL)
C2 (creatine ethyl ester HCL)
CrE2 (creatine ethyl ester HCL)
CR100 (creatine anhydrous)
Creatine Alpha-ketoglutarate (AKG)
Kre- Alkalyn Creatine
When buying Creatine check how much REAL CREATINE you are getting! MuscleTech's
CellTech Fruit Punch for example only contains 200 grams (total) of creatine
monohydrate per 2020 gram container. This means that over 1800 grams of powder
contained within this one container is not creatine monohydrate. So when you
take out 2 of the recommended scoops (101 grams) are you getting the full 10
gram serving of creatine or is it more or less or none at all. Due to the
manufacturing process, mixing, distribution, settling, transport, and handling,
the makers cannot guarantee that the contents will be evenly distributed. This
explains in part why some people have had very poor results with some creatine
products.
Types of Creatine:
Creatine Monohydrate:
One of the original forms of creatine introduced in supplement form, monohydrate
has been the type most widely researched and promoted.
Pro:
one of the lowest priced forms of creatine
available in a wide variety of supplements
Con:
unless it has been micronised, the chances of gastrointestinal problems will be
higher due to the larger particles
Creatine Citrate:
This is one creatine molecule with the addition of one molecule of citric acid.
The addition of citric acid is believed to help in energy metabolism.
Pro:
dissolves easily due to its solubility
Con:
only contains 2 grams of actual creatine per 5 gram serving
sour taste
Creatine Phosphate:
Before creatine can be utilised by the body it must first bond with a phosphate
molecule. The belief was that by adding the phosphate molecule externally that
the creatine phosphate would, when consumed, be utilised more quickly. However,
this theory has never been proven.
Pro:
n/a
Con:
more expensive than monohydrate
very few products are currently available
Creatine Malate:
This is one molecule of creatine bound with one molecule of malic acid. Malic
acid is commonly found in fruits and vegetables but it is also produced
internally by the human body. It plays a part in deriving adenosine triphosphate
(ATP)from food.
Pro:
dissolves easily
less chance of gastrointestinal problems
Con:
supporting research is hard to find
Creatine Pyruvate:
Pyruvate is a by-product produced in the body during the normal metabolism of
carbohydrates and proteins. It is also present in foods such as red apples,
cheese, and wine. When glucose breaks down, it produces two molecules of
pyruvate. If oxygen levels in the body are high, the pyruvate breaks down into
carbon dioxide through a series of reactions as part of the Krebs Cycle (a
series of chemical reactions within all living cells that utilise oxygen as part
of cellular respiration). If oxygen levels in the body are not sufficient, then
the pyruvate is broken down, anerobically, to form lactic acid. As lactic acid
levels in the body increase, performance levels decrease. As mentioned earlier,
creatine has lactic acid buffering properties and so is believed to extend this
process and the user's ability to workout longer. Pyruvate also stimulates
glucose extraction from the bloodstream and into muscle tissues.
Pro:
increased endurance
Con:
high intakes of pyruvate can trigger gastrointestinal problems such as gas,
bloating, and diarrhoea
Creatine Tartrate:
This is one molecule of creatine bound to one molecule of tartaric acid.
Tartaric Acid is found in wines and is used in foods to produce a sour taste or
as an antioxidant. This is one of the newer forms of creatine currently
available but very little is known about its future. Refer to the last point
under 'Con:'.
Pro:
high stability rate
Con:
very few products are currently available
tartaric acid inhibits the production of malic acid and is a muscle toxin which
can cause paralysis or death at a dosage above 12 grams
Magnesium Creatine:
The presence of the magnesium is thought to protect the creatine from the acidic
conditions of the stomach and thus enable more of the creatine to be absorbed
and utilised. Magnesium is also utilised in the conversion of creatine phosphate
into ATP. This bonded form of creatine has also been found to increase fluid
uptake by muscle cells.
Pro:
preliminary research has supported all of the above claims
Con:
very expensive
Creatine Anhydrous:
This is creatine monohydrate with the water molecule removed.
Pro:
provides 4.70 grams of actual creatine per 5 gram serving
Con:
similar side effects as monohydrate
Creatine Ethyl Ester HCL (hydrochloride):
In this case, creatine is bonded with an ester (ethyl alcohol). An ester is a
compound formed from the reaction between an acid and an alcohol. Since creatine
monohydrate is not very soluble in water, it has difficulty penetrating muscle
cell membranes which are made up of lipids (fats). Also, once it comes in
contact with any liquid, it gives up its' hydrogen atom which results in it
being positively charged at one end and negatively charged at the other. As a
result, creatine must rely on transporters to help it bridge this membrane. As
it sits outside the cell membrane, it draws in more water (outside the cell),
producing the bloating people associate with taking creatine monohydrate. It
also begins to degrade and form creatinine. The addition of an ester means that
the creatine does not have to rely on transporters to obtain access to muscle
cells. Once inside the muscle cell, the ester is removed and the creatine begins
to draw water into the cell.
Pro:
enhanced absorption rate
lower dosage rate
side effects associated with monohydrate are reduced
Con:
more expensive form of creatine
Creatine Alpha-Ketoglutarate (AKG):
As mentioned above for creatine ethyl ester, creatine relies on transporters to
help it bridge the cell membranes of muscle tissues. When an insufficient number
of transporters are available, the creatine will sit outside the muscle where it
will not be utilised. AKG acts as a transport molecule and thus enables more
creatine to enter muscle cells and be utilised at a quicker rate. You will also
see AKG used with other supplements to act in a similar manner.
Pro:
enhanced absorption rate
Con:
more expensive form of creatine
Micronised Creatine:
This is a finer powdered version of creatine monohydrate.
Pro:
less chances of gastrointestinal problems
is available in more and more products
Con:
more expensive than monohydrate
Effervescent Creatine:
This will either be a creatine monohydrate or creatine citrate with the addition
of bicarbonate (sodium or potassium) and citric acid. It is the bicarbonate and
citric acid which produces the reaction when water is added. The creatine is
dissolved and suspended as a result of the reaction. Creatine citrate is more
soluble in water than monohydrate and therefore would be the better choice of
the two if using this type of a delivery system. However, the actual creatine
content of citrate based creatines is low (2.0 grams per 5.0 gram serving).
Pro:
dissolves more readily
Con:
sugar content in some products can be high
actual creatine content may be low
manufacturing process and packaging of the finished product must adhere to
strict guidelines
few products are currently available
Creatine Titrate:
This is very similar to effervescent creatine but without the fizzy effect.
Pro:
greater solubility by changing the pH value when added to water
Con:
few products are currently available
Liquid Creatine:
Muscle Marketing USA fined $70,000 for false claim: Wednesday, 14 July 2004,
5:41 pm Press Release: Commerce Commission Muscle Marketing USA fined $70,000
for false claims about sports performance product Muscle Marketing USA Limited
has been fined $70,000 in the Auckland District Court today for breaching the
Fair Trading Act in relation to its sports performance enhancing product ATP
Advantage Creatine Serum. In sentencing, Judge Everitt said that Muscle
Marketing's claims about its product were so far from actual reality that it was
a very bad case of a misleading statement. "The company was highly culpable. On
a scale of 1-10 it was 8." The Commerce Commission investigated claims that
Muscle Marketing USA was making false representations in promotional material
and labelling regarding the quantity of creatine in its ATP Advantage Creatine
Serum product and the benefits that people would get from using it. Creatine is
a nutrient that is synthesised from food by our bodies. It provides the energy
muscles need to move and is often used by athletes to improve their sports
performance. Fair Trading Director Deborah Battell said that in the Commission's
view, Muscle Marketing USA falsely represented that 5ml of its serum yielded the
equivalent of 2500mg of creatine. "Tests conducted on the serum showed that 5mls
of the product contained only around 11.5mg of creatine. This means that on the
basis of Muscle Marketing USA's recommended daily dose of 5mls a day, athletes
would not be able to obtain the benefits as represented. "A 150ml bottle of the
serum retails for $119.95. This is a significant outlay, particularly when
people are paying this price based on misleading representations" Ms Battell
said. "It's another example of a product where consumers are utterly reliant on
claims being made by the company because they have no realistic means of
checking the actual composition or effectiveness of the product," said Ms
Battell. In sentencing, Judge Everitt commented that people will always have
pride in their appearance and are vulnerable to this kind of marketing. The Act
is designed to create fair trading and to protect the public from "snake oil
people and the like", he said.
Pro:
n/a
Con:
despite advances made in trying to suspend creatine in a liquid, it is still
considered an unstable form
So - be careful which Creatine you buy - by only selling the highest grades at
the lowest prices this is why we have become THE LARGEST
