Pure Glutamine Support for Recovery and Performance

Bodybuilding.com Signature L-Glutamine delivers a simple, effective formula centered around one key ingredient, pure L-glutamine. Each serving provides 5 grams, helping replenish levels that can become depleted during intense training. This makes it especially useful for athletes and lifters who want to support recovery and maintain performance without adding unnecessary ingredients to their stack. The micronized form also helps improve mixability and absorption, making it easy to use daily.

Muscle Recovery, Preservation, and Immune Support

Glutamine plays a critical role in muscle recovery by helping reduce breakdown and supporting protein balance after workouts. It also contributes to muscle cell hydration, which can support a more optimal environment for growth and repair during demanding training phases. Beyond muscle support, glutamine is used by immune and gut cells as a primary fuel source, helping support overall health and recovery when your body is under stress from frequent workouts.

Easy to Use, Stackable, and Built for Consistency

Signature L-Glutamine is unflavored and mixes easily into water, protein shakes, or intra workout drinks, making it simple to add into any routine. Its straightforward formula allows it to stack seamlessly with pre workouts, EAAs, or protein without overlapping ingredients. Designed for consistent daily use, it provides a reliable way to support recovery, maintain muscle, and keep performance moving forward over time.

Glutamine (5 grams)
Glutamine is a vital amino acid that plays a crucial role in muscle recovery, preserving lean muscle mass, and maintaining overall health, particularly during intense physical stress such as rigorous training or endurance exercises. As a key component in protein synthesis, glutamine helps prevent muscle breakdown and promotes faster recovery. Beyond its role in muscle recovery, glutamine serves as a primary energy source for immune cells, like lymphocytes and macrophages, and intestinal cells (enterocytes), making it essential for maintaining immune function and gut health. This is especially important for athletes who experience high levels of physical stress. By fueling these cells, glutamine helps prevent immune suppression that often occurs after intense or prolonged exercise, earning it the nickname "immunonutrient." It supports overall well-being, ensuring athletes can perform at their best while recovering efficiently.

Mix 1 level scoop with 4-6oz of water or your favorite beverage . For optimal results, take at least 1 serving post work out or prior to bed.
