Peptide Transported Glutamine™
G-TEK™ - Peptide Transported Glutamine™ by ThermoLife International are new
technologically advanced glutamine products that are clinically proven to be more effective at raising glutamine levels
than any free form glutamine product on the market.(3)
G-TEK RENDERS ALL FREE FORM L- GLUTAMINE OBSOLETE!
With the release of G-TEK™ Peptide Transported Glutamine™ ThermoLife International
sets the new standard in glutamine supplementation. Recent clinical studies have proven that the technologically advanced
Peptide Transported Glutamine in G-TEK are more stable and more effective at raising glutamine levels than any free
form glutamine product on the market. (3)
Clinical science and practical experience have proven that free form L-glutamine is inherently unstable, it quickly
degrades in solution and does not reach the blood in concentration levels needed to replenish healthy levels of glutamine.
In addition, a little know fact, is that almost all of the research done on free from glutamine supplementation was done
in hospitals on subjects receiving the glutamine intravenously. Just because you buy and take something called glutamine,
does not mean you are going to benefit from all the metabolic functions that glutamine performs.
On the contrary, the Peptide Transported Glutamine in G-TEK has been clinically proven to be highly stable in
the body, very soluble in solution, readily absorbed by the digestive tract, and efficiently retained in the blood and
body tissues where it enters muscle cells fast and performs the essential metabolic functions of glutamine including;
increasing muscle mass, preventing catabolic muscle loss, raising growth hormone levels, improving immune functions,
stabilizing blood sugar and preventing over training syndrome, just to name a few.
The benefits of Glutamine supplementation cannot be fully experienced from free form L-glutamine. The only practical
way to effectively elevate glutamine levels is with the clinically proven Peptide Transported Glutamine in G-TEK . ThermoLife
International G-TEK products now render all free form glutamine products obsolete Start taking a ThermoLife G-TEK product
today and feel the difference for yourself.
Why Glutamine?
Glutamine is a "conditionally essential" amino acid. Normally, an "essential" amino acid is one that the body must ingest
through nutrition, because it can't manufacture that amino acid. But, under certain conditions - of stress, disease,
malnutrition, or bodily injury - a "non-essential" amino acid, which the body manufactures, can become depleted and "conditionally
essential." Glutamine is the most important of these, for its many vital functions in normal body function and athletic
training.
Glutamine is the most abundant amino acid in the body, constituting more than 50% of the free amino acid pool in body
cells. It is normally available to synthesize proteins, the building blocks of muscle, and provide many more beneficial
functions, as we'll explain.
One of Glutamine's primary metabolic functions is that it helps to regulate glucose metabolism. Glutamine converts to
glucose without changing insulin or glucagon levels. These are the hormones that regulate blood sugar. During carbohydrate
depletion, glutamine can increase body fat loss without loss of lean body mass. Glutamine provides a high-energy source
for maintaining muscle function, by converting to glucose, which turns into glycogen stores in the muscles.
Glutamine is a key contributor to repair of gastrointestinal tract cells and the immune system - where it contributes
to nucleic acid synthesis, which is essential to cell growth throughout the body. And because glutamine helps the intestinal
tract resist the passage of bacteria into the bloodstream, glutamine supplementation helps hard-training athletes fight
off infection, and helps the person with illness or injury to recover faster.
Glutamine has been proven to release growth hormone. In one study just 2 grams of glutamine raised growth hormone levels
more than 400%, increased growth hormone levels have a strong anabolic effect on muscle growth. Glutamine also converts
to glutathione, a powerful anti-oxidant that helps to prevent cellular breakdown.5 And glutamine crosses the blood-brain
barrier, converting inside the brain to glutamic acid, which makes GABA (gamma amino butyric acid), which boosts mental
alertness and relaxes the body. As a neurotransmitter in the brain, glutamine is a precursor to other neurotransmitters,
so glutamine levels can affect the brain and nervous system.
For the muscles, a glutamine shortage can cause the muscles to be broken down, releasing glutamine to the rest of the
body, leading to muscle wasting. Especially for body-builders and other athletes undergoing rigorous training workouts
on a regular basis, it is crucial to ensure that the body's stores of glutamine are maintained at healthy levels, through
supplementation before and after training.
Glutamine is critical to the intestines and the immune system as a fuel, and is used to synthesize DNA, enzymes and
proteins in all active cells in your body - a building block for your muscles.1 Glutamine also helps maintain overall
body health by regulating the acid / alkaline balance of the blood.
So, by helping to regulate glucose metabolism, glutamine helps maintain the level of glycogen stored in your muscles
as fuel for strenuous exercise. Adequate levels of glutamine are also critical to your brain, where glutamine is a neurotransmitter
and precursor to another key neurotransmitter, keeping your brain functioning normally. And healthy blood levels of glutamine
are an important part of anti-oxidant defenses, and maintaining the blood's critical acid/alkali balance.
Under normal conditions, our bodies make adequate amounts of glutamine from other amino acids. But after strenuous physical
exercise, when fighting an illness, or if the body has been damaged by injury, our bodies run low on glutamine, and are
more susceptible to infections.2 At these times of physical stress, when our bodies cannot make enough glutamine, we
need to take additional amounts into our bodies through food or supplementation.
Athletes in training, whether aerobic or anaerobic, create this level of glutamine-depleting stress on the body during
exhaustive training. Strenuous exercise lowers the blood concentration of glutamine. Sometimes, the body's glutamine
levels do not recover before the next training session. Studies have shown that an athlete in the overtraining syndrome
- where the athlete works harder but his or her performance does not improve - has chronically low levels of glutamine.
In this condition, the athlete may lose muscle mass, is more prone to injury and infection, and may suffer digestive
problems and a loss of motivation for exercise.
Glutamine Supplementation
Maintaining healthy blood levels of glutamine is necessary to the athlete who wants to optimize all critical body functions,
and derive the maximum benefit from his or her training regimen. Before, during and after training, glutamine levels
must be maintained, to provide its vital role in regulating energy, repairing any lost muscle tissue, maintaining and
building added muscle, sustaining elevated levels of growth hormone and its powerful anabolic effect, nourishing the
immune system, keeping brain and nerve function at a high level, and maintaining the acid/alkali blood balance.
The athlete must be sure to build up his or her blood glutamine level pre-workout, so the entire body has enough reserve
glutamine to prevent glutamine depletion during or after a strenuous workout. Stored glutamine reserves are crucial to
being able to function at a high level during an athletic workout. In body building and strength training, glutamine
is both anabolic - muscle building and anti-catabolic - muscle protecting.
Pre-loading of glutamine via supplementation, in preparation for a strenuous workout, is the key to ensuring adequate
reserves and preventing depletion. Mid-workout, a healthy blood level of glutamine is critical to maximum performance,
by sustaining high-level muscular, nerve, brain, intestinal, and blood functioning. Post-workout, supplementation is
essential to restoring blood levels of glutamine burned up by exertion. The rebuilding of energy levels and restoration
of the protein building blocks supplied by glutamine are key to preparing for, performing, and afterward sustaining the
full benefit of a strenuous workout. Glutamine supplementation heightens your preparation, performance, and recovery
from strenuous workouts.
Peptides Bonded Glutamine
Physicians have recognized that glutamine supplementation is needed under conditions of stress. These conditions run
a parallel to the hard working athlete. In theses conditions physicians have administered free for L- glutamine to clinical
patients intravenously.3 But, they discovered that free form, unbonded glutamine is highly unstable in the body, breaking
down so that it is not bioavailable, and does not reach the blood concentration levels needed to replenish healthy levels
of glutamine.
Peptide-bonded amino acids, including glutamine, are clinically proven to be highly stable in the body, very soluble
in solution, readily absorbed by the digestive tract, and efficiently retained in the blood and body tissues. Peptide-bonded
amino acids are administered to patients with burns, inflammatory disease, cancer and AIDS, and are used in oral supplements
for high-output athletes.
Peptides are amino acids linked to each other by strong, peptide bonds. Strings of amino acids make up short, medium,
or long-chain peptides, which in turn are the main components of protein. Short-chain peptides are amino acids linked
in groups of two (dipeptides), three (tri-peptides), or more.
Di- and tri-peptides are very stable in solution, are very soluble - they dissolve completely in solution - and are
quickly and easily absorbed by the human digestive tract.4 They are totally bioavailable, since they are retained - not
excreted - by the body and are ready for use in building and repairing muscle, supplying energy, serving as the building
blocks of DNA, protein and muscle, converting to antioxidants, releasing anabolic growth hormones or any of their other
vital functions.6
Peptide-bonded glutamine is selectively absorbed by muscle tissue in need of repair and replenishment.6 Being easily
absorbed and totally bioavailable, peptide-bonded glutamine enters muscle cells fast, breaks down to free glutamine,
and performs its essential metabolic functions. Peptide-bonded glutamine is thus more efficient, more effective, and
clearly superior to free-form glutamine for supplementation of the athlete concerned about maintaining his or her pre-,
mid- and post-workout glutamine levels.
Why is the G-TEK-glutamine delivery system in tablet form?
If you have ever worked with peptide-bonded glutamine you know that powdered peptide-bonded glutamine has a definite
limitation. Taken orally, singly or in combination, with juice, protein drinks, or water, they do not mix well and have
a strongly bitter taste, and for the most part are unpalatable. We have tried previous powder-form supplements of peptide-bonded
glutamine but it doesn't work.
This limitation has recently been overcome by ThermoLife International's peptide bonded glutamine delivery system in
tablet form. ThermoLife International is the first to offer such an essential glutamine supplement in a form that is
practical, convenient and affordable (as always you will see the other companies copy us). Clinical science and practical
experience has proven that that free form L-glutamine is inherently unstable, and quickly breaks down in solution and
is basically worthless to the athlete as a powdered supplement. Research has shown that peptide bonded glutamine is very
stable and soluble, and readily absorbed from the digestive tract. In fact some research indicates that peptide-bonded
glutamine is more than 22 times more bio-available than straight free form L-glutamine. That clearly makes the G-TEK-Peptide
Transported Glutamine products by ThermoLife International the most bio-available and most cost effective glutamine products
on the market today. Don't even waste your time finishing your existing bottle of free form L-glutamine. Start taking
a G-TEK product today and feel the difference.
Clearly the only choice for glutamine supplementation is one of the G-TEK - Peptide Transported Glutamine products,
exclusively manufactured by ThermoLife International.
