L-Glutamine

L-glutamine – support for building muscle mass

Any athlete who is looking for supplements to support rapid muscle mass building without burdening the digestive system, including the intestinal tract, should be interested in nutritional supplements with pure l-glutamine. It is an amino acid produced naturally by the human body. L-glutamine is involved in many metabolic processes, significantly speeding up regeneration processes or increasing immunity. Proven supplements for athletes and amino acid supplements for bodybuilders also improve concentration and reaction speed. In the Bicepsshop shop’s offer you will find top-class products of such brands as OLIMP or ALLNUTRITION.

What is L-glutamine?

L-glutamine is an endogenous amino acid included in the glutamic acid amide, which is produced independently by the human body. However, when building muscle mass, participating in competitive and amateur sports, as well as during increased physical exertion, it is important to supplement the daily requirement of glutamine through appropriate supplementation. Both powdered amino acid supplements and sports supplements in capsules are ideal. Their regular use – of course in accordance with the manufacturer’s instructions and preferably following prior consultation with a dietician or personal trainer – guarantees many positive effects.

Why use glutamine supplements?

Among other things, glutamine supplements are worth using for:

• Improved body metabolism – glutamine plays a significant role in the process of nitrogen metabolism in the body. In addition, it removes unnecessary ammonia from the body, which is a by-product of protein metabolism. L-glutamine is therefore a nutrient for athletes, which significantly improves metabolism, e.g. during weight reduction, weight loss or building muscle mass with the use of protein supplements.
  Supplementation of energy needs during and after exercise – L-glutamine is just as necessary for exercise as BCAAs. This substance replenishes the energy reserves of working muscles and at the same time prevents the loss of glycogen, which is a valuable fuel for muscle tissues.
• Faster results in the building of muscle mass – L-glutamine, by replenishing energy reserves in muscles, promotes their regeneration and also helps them to work properly during increased exertion. It is an important amino acid that promotes faster results. We are talking about both building muscle mass and increasing strength and muscle performance.
  Increased resistance – L-glutamine is an element that contributes to the formation of skeletal muscles. Thus, it participates in the process of their reconstruction. The amino acid increases the body’s performance and immunity: it provides support for the regeneration of muscle structures and helps wounds to heal rapidly!
• Supports the body’s cognitive processes – after crossing the blood-brain barrier, the amino acid is converted into glutamic acid, a substance that is extremely energetic for the brain. Thus, L-glutamine is seen as an important support for cognitive functions, e.g. memory.
  Protection of the digestive system and restoration of the intestines – it is worth knowing that l-glutamine, an endogenous amino acid, is one of the most important energetic components for the muscle covering the intestines. This means that its supplementation supports their proper function. In addition, the amino acid is used in people with certain digestive disorders and during the healing of wounds in the stomach or duodenum (e.g. in the course of peptic ulcer disease).

L-glutamine – how to use supplements with L-glutamine?

Every amino acid supplement should be used according to the manufacturer’s recommendations on the packaging. It is also a good idea to consult personal trainers and nutritionists who can show you how to most safely supplement your diet with high-quality glutamine. When it comes to products that are worthwhile for professional athletes, amateur athletes, body-builders, people losing weight or looking for gut-safe nutrients, we recommend several products from the extensive Bicepsshop range!

L-glutamine capsules

L-glutamine in capsules is available from Bicepsshop. We encourage you to purchase, among others, 1400 mg of crystalline, pharmaceutical, highly micronised l-glutamine GLUTAMINE 1400 MEGA CAPS – 120 CAP. OLIMP brand. The product relieves symptoms of fatigue, improves the digestive tract, and helps you shape your figure and work on your own fitness!

L-glutamine powder

Athletes and bodybuilders are keen to use glutamine powder. We encourage you to order the products: GLUTAMINE XPLODE POWDER – 500g; GLUTAMINE RECOVERY AMINO – 250g; L-GLUTAMINE POWDER – 250g. Such amino acid supplements are invaluable support for training. Supplements with l-glutamine support the reconstruction of the intestinal barrier, relieve inflammation, support the building of muscle mass, stimulate anabolic processes in the body and inhibit post-workout catabolism!

L-glutamine – recovery, immunity, and muscle protection in a single capsule

L-glutamine is one of the most important endogenous amino acids, and its role in sports and supplementation cannot be overstated. Under normal physiological conditions, the body can produce it on its own. However, during periods of intense physical activity, stress, or illness, the demand for glutamine rises sharply-making external supplementation a smart choice. For those engaged in strength training, endurance sports, or physique-focused workouts, glutamine is a key nutrient that supports recovery, immunity, and protection against muscle breakdown.

What is L-glutamine?

L-glutamine is a naturally occurring amino acid, found in high concentrations in skeletal muscle. It plays several crucial roles in the body:

• Supports the repair of muscle fibres damaged during training
• Participates in nitrogen transport between cells-important for recovery and anabolic processes
• Strengthens the immune system by nourishing intestinal cells and supporting gut barrier function
• Helps maintain acid-base balance and stabilises blood glucose levels

Glutamine makes up around 60% of the free amino acid pool in muscle tissue. A post-workout deficiency can slow down recovery, reduce endurance, and trigger catabolism. That’s why it’s essential to replenish it during times of increased physical stress.

Who should take L-glutamine supplements?

• Strength athletes-especially those training frequently and with high loads
• Endurance athletes such as runners, triathletes, and cyclists
• Individuals on a cutting diet who are at risk of muscle breakdown
• Anyone looking to boost immune health and recovery
• Those with gut health issues or increased susceptibility to illness

When is the best time to take L-glutamine?

Glutamine can be used at different times of day depending on your goal:

• Post-workout – to support muscle recovery
• Before bed – to aid nighttime anabolic and repair processes
• First thing in the morning on an empty stomach – to protect against overnight catabolism
• During a cutting phase – to support immunity and prevent muscle loss

For athletes, the recommended daily dose typically ranges from 5 to 15 grams, divided into 2–3 servings throughout the day.
