Sports Research L-Glutamine delivers 5 grams of pure, unflavored L-glutamine per serving in a 17.64-ounce container. This amino acid is formulated to support muscle recovery after exercise, assist immune system function, and promote intestinal barrier integrity. The product is derived from plant-based fermentation, making it suitable for vegetarian and vegan dietary patterns. Each scoop provides a consistent dosage without added fillers, artificial colors, or preservatives. The fine, white powder dissolves easily in water, juice, or smoothies, allowing for flexible incorporation into daily nutrition routines. L-glutamine is the most abundant free amino acid in the body and plays a key role in protein synthesis and nitrogen transport. By supplying a concentrated source, this supplement aims to replenish glutamine levels that may be depleted during intense physical training or periods of stress. For individuals engaged in regular resistance or endurance exercise, it may help reduce muscle soreness and shorten recovery time.

Additionally, glutamine serves as a primary fuel source for enterocytes, supporting healthy gut lining and digestive function. Immune cells also rely on glutamine for optimal activity, contributing to overall immune defense. The 17.64-ounce size offers a practical supply for sustained use, with each serving being easy to measure using the included scoop. The absence of gluten, soy, and GMOs further enhances its appeal for those with dietary sensitivities or preferences. This formulation is not intended to diagnose, treat, cure, or prevent any disease, but rather to provide foundational nutritional support. Consistent use as part of a balanced diet and training regimen may aid in maintaining muscle mass, enhancing recovery, and supporting gastrointestinal wellness. The unflavored profile ensures compatibility with a wide range of beverages and recipes without altering taste. Storage in a cool, dry place preserves the powder’s quality over time.

This product represents a straightforward approach to meeting increased glutamine demands resulting from physical activity and lifestyle demands. Its measurable 5-gram dose aligns with typical research-backed levels for performance and health benefits. Price-wise, it offers a cost-effective option compared to many single-ingredient glutamine supplements on the market, providing value for those prioritizing recovery and immune support. The brand’s commitment to third-party testing and quality assurance adds a layer of reliability. Users seeking a clean, effective amino acid supplement for everyday use may find this product suitable for integration into their health routine.
