L-Glutamine, 500 mg: Intestinal Recovery, Muscle Recovery and Strong Immunity – Essential Amino Acid for Digestive Barrier Integrity and Cellular Energy

L-Glutamine, 500 mg, Life Extension is a premium dietary supplement that provides L-glutamine in free form, an amino acid with a central role in maintaining intestinal health, supporting the immune system and tissue recovery after effort or metabolic stress. Glutamine is the most abundant amino acid in the body and is intensely used by cells with rapid turnover, such as enterocytes (intestinal mucosal cells) and immune system cells. In periods of increased demand—intense physical effort, stress, unbalanced diet or recovery after various aggressions—glutamine needs can increase significantly, and reserves can be consumed faster than they are replenished.

The intestinal mucosa represents a complex barrier between the external environment (food, bacteria, toxins) and the body's internal environment. When this barrier is compromised, digestive discomfort, deficient nutrient absorption and excessive activation of the inflammatory response may occur. Glutamine is considered a major "fuel" for intestinal cells, contributing to their regeneration and integrity, as well as maintaining balanced digestive function. At the same time, glutamine supports muscle recovery and recovery processes, being involved in nitrogen balance, protein synthesis and metabolic stress regulation.

Through L-glutamine supplementation, the body can benefit from targeted support for the gastrointestinal tract, immune system and general recovery capacity, especially in periods when resources are intensely demanded.

Detailed Benefits of L-Glutamine, 500 mg

• Supporting intestinal barrier integrity and digestive mucosal health

The intestine is not just a digestive organ, but also a major center of immunity and nutrient absorption. Intestinal mucosal cells constantly need energy to regenerate and maintain an efficient barrier. Glutamine is one of the main energy sources for enterocytes, contributing to maintaining the structure and function of the mucosa.

When the intestinal mucosa is overstressed, the following may occur:
- Digestive discomfort and food sensitivity
- Weaker nutrient absorption
- Microbiome imbalances and local inflammation

Through L-glutamine supplementation, the following can be supported:
✅ Intestinal cell regeneration – support for mucosal recovery
✅ Maintaining a strong digestive barrier – functional protection
✅ Improved gastrointestinal comfort – supporting digestive balance
✅ Optimal nutrient utilization – supporting efficient absorption

This effect makes glutamine particularly relevant for people pursuing digestive health and intestinal balance.

• Support for microbiome balance and reducing intestinal stress

The intestinal microbiome is a complex ecosystem, influenced by diet, stress, sleep and mucosal integrity. A healthy mucosa contributes to maintaining a balanced relationship between the body and intestinal flora. Glutamine can indirectly support the microbiome by maintaining intestinal integrity and supporting an environment favorable to stable digestive function.

Benefits may include:
✅ Support for a balanced intestinal environment – favorable to normal function
✅ Reduction of discomfort associated with digestive sensitivity – by supporting the mucosa
✅ Maintaining comfortable transit – support for normal physiological functions
✅ Supporting digestive tolerance – in periods of variable diet

Through this action, glutamine becomes an important ally for digestive "resilience."

• Supporting the immune system by fueling defense cells

A significant part of the immune system is located at the intestinal level, and immune cells use glutamine as an energy substrate during activation periods. Under stress conditions, the body prioritizes resources toward defense mechanisms, and glutamine can become a limiting nutrient.

Through L-glutamine intake, the following can be supported:
✅ Energy for immune cells – metabolic support for defense response
✅ Supporting intestinal immune function – direct link to digestive barrier
✅ Maintaining body resilience – in demanding periods
✅ Supporting inflammatory balance – through metabolic and cellular support

This function is especially important in demanding seasons or in periods of accumulated fatigue.

• Muscle recovery and tissue restoration after effort

Glutamine is stored in large quantities in muscles and participates in nitrogen balance, an essential element for maintaining muscle mass and recovery after effort. In intense physical activities, glutamine levels can decrease, and this can influence recovery and resistance.

Recovery support may include:
✅ More efficient muscle recovery – tissue support after effort
✅ Maintaining nitrogen balance – support for muscle integrity
✅ Supporting protein synthesis – key process in recovery
✅ Reducing the impact of physical stress – resilience in training periods

These benefits make the product relevant for athletes, active people and anyone who wants recovery support.

• Cellular energy and metabolic support in periods of stress

In metabolic stress situations (intense demand, insufficient sleep, uneven diet), the body needs nutrients that support cellular function and recovery. Glutamine can contribute to energy balance and support for organs that consume resources intensely, such as the intestine and immune system.

Through this support, the following can be favored:
✅ More efficient cellular function – support for basal metabolism
✅ Better adaptation to stress – through energy supply for key cells
✅ Improved general vitality – through digestive and immune support
✅ Metabolic resilience – in demanding periods

• Free form amino acid for rapid availability

The product contains L-glutamine in free form, which means it is rapidly available for metabolic use, without requiring prior breakdown from complex proteins. This characteristic is valuable when the body needs targeted and efficient intake.

Advantages include:
✅ High bioavailability – rapid use at the cellular level
✅ Direct support for intestine and immunity – tissues with increased need
✅ Simple and concentrated formula – precise support, without redundant ingredients
✅ Suitable for demanding periods – when needs increase
