Glutamine

Gaspari Glutamine is a single-ingredient, unflavored powder delivering 5g of pure L-Glutamine per scoop. L-Glutamine is the most abundant amino acid in skeletal muscle, making up roughly 60% of the free amino acid pool. Your body produces it naturally, but during intense training, dieting, or illness, demand can exceed supply. Available in 300g (60 servings) and 1kg (200 servings). Contains no allergens and is non-GMO, keto-friendly, and lab-tested.

Glutamine fuels intestinal cells (enterocytes), powers immune cells (lymphocytes and macrophages), and transports nitrogen between tissues. For direct muscle building in healthy athletes eating adequate protein, the research is limited. The stronger evidence supports gut barrier integrity, immune defense during heavy training, and recovery during physical stress like hard dieting or overreaching. This is best understood as a recovery and wellness supplement, not a traditional muscle-builder.

Absolutely! Gaspari Glutamine is made with ultra-pure L-Glutamine and adheres to strict quality standards. Always consult with a healthcare professional if you have specific concerns.

Most research uses 5g to 10g daily. Gaspari Glutamine delivers 5g per scoop, so one to two scoops covers the effective range. Timing matters less than daily consistency because glutamine supports ongoing processes like gut lining repair and immune cell fueling that happen around the clock. Common approaches include one scoop post-workout and one before bed. On rest days, take your dose at any convenient time.

There’s no need to cycle off Glutamine. It’s a naturally occurring amino acid in your body, safe for long-term use when taken as recommended.

Yes, Gaspari Glutamine mixes well with other supplements like protein powders and pre-workouts, enhancing your fitness routine without compromising results.

They serve different purposes with minimal overlap. BCAAs signal muscle protein synthesis and support intra-workout endurance. EAAs provide all nine essential amino acids for complete muscle tissue construction. Glutamine supports gut health, immune function, and recovery from physical stress. It does not trigger muscle protein synthesis the way Leucine does. If your goal is muscle building, EAAs are more directly relevant. If staying healthy and recovering during hard phases is the priority, glutamine fills that role. They can be taken together.

Under normal training conditions, dietary glutamine from meat, eggs, and dairy is likely sufficient. Glutamine becomes conditionally essential when demand exceeds supply: intense training blocks, caloric restriction, illness, or significant stress. In these scenarios, your body pulls glutamine from muscle to fuel immune cells and gut repair, impairing recovery even with adequate protein intake. Supplementation is most valuable during these high-demand periods rather than as a year-round staple.

Double sessions shrink your recovery window and dramatically increase demand for repair resources. Glutamine is one of the first amino acids depleted during intense exercise because muscle tissue, immune cells, and gut lining all compete for it simultaneously. When stores run low, recovery across all three systems suffers. Adding 5g between sessions and 5g before bed helps maintain the pool all three systems draw from.

Intense training temporarily suppresses immune function by raising cortisol and depleting glutamine stores. Your immune cells use glutamine as their primary fuel. When training volume is high or calories are restricted, production cannot keep up with demand, leaving immune cells under-fueled. This is why upper respiratory infections spike during heavy training phases. Supplementing 5 to 10g of L-Glutamine daily helps maintain the pool your immune system draws from.
