Product Information:

Ultra Pure Glutamine Powder provides 4,50 mg of Pure L-Glutamine.

Glutamine is the most abundant amino acid in the body, comprising more than 60% of the free amino acid pool in skeletal muscle and more than 20% of total circulating amino acids. This conditionally essential amino acid is extremely important in overall health, athletics and in building and maintaining muscle. For example, hormones destructive to muscle and brain tissue such as cortisol are released at times of stress and increase the demand for free glutamine. And, during conditions of calorie restriction or dieting glutamine and BCAA’s act to stave off catabolic hormones and prevent muscle wasting. The majority of nitrogen lost from calorie restriction and dieting occurs when levels of glutamine in the body are insufficient. Therefore, glutamine supplementation can be used to reverse this condition by promoting nitrogen retention and preventing muscle loss and immune system down regulation. Supplementation of this amino acid can also markedly improve testosterone to cortisol ratios and thus, potentially increase muscle mass. Additionally, glutamine can also increase anabolism (muscle building) by increasing muscle cell volume.

Just two grams of glutamine has been shown in research studies to increase growth hormone levels by over 400% and also repair and maintain the integrity of the intestines and even have a 92% cure rate of ulcers within four weeks of use.

Research indicates that the metabolic requirement for glutamine is greatly increased during times of stress such as fasting, illness, injury and/or intense athletic training. Further, the immune system depends on glutamine as a primary fuel source and consequently, the demand for this amino acid increases during periods of immunological stress.

It is important for consumers to note that in purchasing a glutamine supplement, quality should be considered over price. Cheaply priced glutamine is generally indicative of low quality raw materials used in the manufacturing process. With Ultra Pure Glutamine by VPX, you can be assured that you are getting the highest quality free form glutamine available.

Recommended Use:
Mix one teaspoon of Ultra Pure Glutamine with 8oz. of water or your favorite beverage. This supplement can also be taken on an empty stomach prior to retiring to significantly increase Growth Hormone output. Another option for Ultra Pure Glutamine is to consume this amino acid along with Micellean Protein after any type of athletic event or resistance training. For best results use two or three servings daily including non-training days. The Ultra Pure Glutamine/Micellean supplement strategy should always be utilized 30 minutes following an intense workout

GL3 L-Glutamine by AST!

Glutamine Is Responsible For Over 35% Of The Nitrogen That Enters The Muscle!

GL3, 2-Aminoglutaramic Acid, is a pure L-Glutamine supplement in crystalline powder form. Glutamine has become more prominent as new studies reveal its unique contribution to protein synthesis (muscle growth), anti-proteolytic (prevents muscle tissue breakdown) functions and growth hormone elevating effects.
Increase Muscle Hardness
Increase Muscle Cell Hydration
Increase Protein Synthesis
Increase Muscle Strength
Enhances Recovery
Glutamine provides a critical link in muscle metabolism not shared by any other single amino acid, and GL3 makes utilizing glutamine a realistic and effective endeavor. GL3 is pure, pharmaceutical grade L-Glutamine in an odorless and tasteless powder.

Glutamine is the most abundant single amino acid in the blood and in the intracellular free amino acid pool (most abundant amino acid in muscle tissue). It comprises 61% of the amino acid pool in skeletal muscle. Glutamine’s unique structure, containing two nitrogen side chains, consists of 19% nitrogen - making it the primary transporter of nitrogen into the muscle cell. In fact, glutamine alone is responsible for 35% of the nitrogen that gets into the muscle cell. Glutamine literally drives muscle building nitrogen into the muscle cell where it is synthesized for growth.

Glutamine concentrations fall markedly after training and remain low until complete recovery. What this means is, the very rigors of weight training “leak” nitrogen carrying glutamine from muscle tissue. This fall in glutamine is catabolic to muscle tissue - “The Training Paradox”. Supplementing with glutamine spares free glutamine in muscle tissue, counteracts the fall in muscle protein synthesis, and improves nitrogen balance. Glutamine overcomes “The Training Paradox”.

You train with weights to build muscle. The more intensely you train, and the heavier the overload you subject your muscles to, the greater the growth response will be.

Glutamine is a key factor in muscle growth, and controlling the skeletal muscle/whole body glutamine gradient is critical in maintaining and building muscle tissue. The higher the muscle glutamine levels you can maintain, the less chance you have of falling into catabolism and the faster muscle will grow. But now there is more . . .

We all know growth hormone is an important anabolic hormone. The most important anabolic hormone! It regulates the metabolic processes (including protein synthesis) in almost all tissues throughout the human lifespan. Growth hormone provokes several anabolic actions on skeletal muscle: the uptake of glucose and amino acids, activation of muscle protein synthesis, suppression of muscle protein catabolism, and the utilization of body fat for energy.

“A New Study In The ‘American Journal Of Clinical Nutrition’ Is Set To Shock The Sports Nutrition World!”

Now for the exciting news -
In a recent release of the prestigious American Journal of Clinical Nutrition, the results of a study on glutamine revealed that a single 2 gram oral dose of glutamine elevated circulating growth hormone levels by over 430%! That’s right - 430%! Significant? You bet your ass it is. With GL3 you’ll be able to effortlessly increase your growth hormone levels by over 430%!

By keeping a consistently high level of circulating growth hormone, you are able to combat the catabolic effects of weight training, harness the anabolic activity of increased glucose and amino acid uptake, improve whole body nitrogen retention, and increase lean tissue protein accrual. Supplementing with GL3 L-Glutamine may just be the most effective way of assisting new muscle growth!

How to use GL3 L-Glutamine:
Take 1 serving 2 times daily. How and when you train will determine when you schedule your GL3 dosage.

Train in the morning.
Schedule your first serving about 30 minutes to 1 hour before your morning workout.
Take 1 serving 30 minutes after you train.
Take 1/2 serving before bed.
Train twice daily.
Take 1/2 serving (5 grams) 30 minutes before your morning workout.
Take 1/2 serving (5 grams) 30 minutes after your morning workout.
Take 1/2 serving (5 grams) 30 minutes before your evening workout.
Take 1/2 serving (5 grams) 30 minutes after your evening workout.
Take 1/2 serving before bed.
Questions And Answers
What’s the best way to take GL3 Micronized L-Glutamine?

The best way to take GL3 is to mix 5 to 10 grams in about 6 ounces of water or juice. Juice might be preferred as it may enhance glutamine uptake into the muscle cell.

You should drink immediately and not let GL3 stay mixed in a liquid for more than a couple of hours.

Now L-Glutamine.

What is Glutamine?

Glutamine is a nonessential amino acid (protein building block) that is made in the body via conversion from a relative amino acid (AA) called Glutamic acid. It is more appropriately considered a “conditionally essential amino acid” and is the most abundant AA in human plasma and muscle.

What are the functional properties of Glutamine?

Glutamine is unique in that like glucose it is one of the preferred energy sources utilized by rapidly proliferating cells. It is a major fuel source for the brain and together with its relatives the stimulant neurotransmitter Glutamic acid and the inhibitory neurotransmitter GABA they form the most abundant amino group in the human brain. Glutamine is also an important fuel source for enterocytes and supports intestinal maintenance and normal function. It has been used clinically to improve nitrogen balance and minimize protein loss in those suffering with catabolic states caused by surgical stress and critical gastrointestinal illness. In combination with N-Acetyl Cysteine Glutamine promotes the production of a powerful cellular antioxidant called Glutathione that plays a critical role in the defense against free radical damage.

Will Glutamine help me with my health maintenance and exercise program?

Glutamine plays a major role in DNA synthesis and serves as a primary transporter of nitrogen into the muscle tissues. It serves to replenish nitrogen loss due to excessive muscle training and speeds up recovery. It is so vital to the building and maintenance of muscle tissue that 60% of the human intracellular amino acid pool is Glutamine. The very fact that muscle is the most important tissue for Glutamine synthesis and storage is evidence of it’s vital role in maintaining positive nitrogen balance and the building of the these important sport support structures.

Glutamine is utilized at a high rate by the cells of the immune system and is required to support optimal white blood cell proliferation (lymphocyte). It is also necessary for the production of hormone like proteins secreted by lymphocytes and macrophages called cytokines that regulate the intensity and duration of an immune response to foreign organisms.

Product Information:

L-Glutamine is the most abundant free amino acid in muscle tissue, and it plays a principal role in protein metabolism, cell volumizing, and anti-catabolism. EAS’s L-Glutamine powder is tasteless and odorless and dissolves quickly and easily in water. It can be added to your favorite protein-containing drink to enhance dietary intake of this conditionally essential nutrient.

L-Glutamine is a nonessential amino acid that can be produced by the body under normal conditions. However, under periods of stress, such as intense workouts, the body may have an increased demand making it a conditionally essential amino acid. Supplementation with L-Glutamine may be an effective way to support sufficient glutamine levels, which may aid in recovery and recuperation.

L-Glutamine may help with:
* recovery and recuperation,
* protecting muscle cells from breaking down, and
* cell volumization.

During periods of high-intensity exercise or increased stress to the body, try 2 to 4 grams (1/2-1 tsp) 2 to 3 times daily. Taking L-Glutamine after workouts or before bedtime, times when muscle tissue typically undergoes repair and recuperation, could be particularly effective.

Product Information:

Glutamine, the forgotten supplement, is comparable to creatine in results, and in some instances, is even better! Known for speeding up muscle recovery, increasing strength and energy enhancement, Glutamine is proven to work!

Pure Glutamine Powder contains the “conditionally essential” amino acid L-Glutamine. Glutamine is the most abundant amino acid in muscle tissue and plays a key role in many bodily functions. During stressful situations (i.e. heavy resistive weight training) the body can lose a large amount of glutamine. A loss of glutamine during exercise may be a signal for protein catabolism (muscle breakdown). Glutamine supplementation has been shown to prevent the loss of body mass through the positive role glutamine plays in protein synthesis and its action as a potent anabolic agent. When muscle glutamine levels are restored and in a positive nitrogen balance muscle synthesis can return to a normal rate. Glutamine also has actions on glucose metabolism and the regulation of gluconeogenesis. Glutamine converts to glucose without changes in either insulin or glucagen, the hormones that regulate blood sugar. During dieting, and times of carbohydrate depletion, glutamine can exert positive effects on the amount of body fat loss as well as the retention of lean body mass.

Glutamine is the single most abundant amino acid found in skeletal muscle and is widely believed to help with muscle cell volumization. Enhance your training and nutrition program with Glutamine Powder. A recent study showed up to a 400% increase in growth-hormone levels when as little as 2 grams of free-form L-glutamine supplement was consumed! Get ripped and huge!
