PURE RECOVERY NUTRITION
Train hard.
Recover with intention.
Goetz Pharmaceutical Glutamine delivers 5 grams of pure, unflavored L-glutamine per scoop—with no fillers, flavors, sugar, or sweeteners.
L-glutamine is the most abundant amino acid in the body’s free amino-acid pool and participates in normal energy metabolism and nitrogen transport.1
WHY GLUTAMINE MATTERS
More than a gym amino acid.
Your body typically produces enough glutamine under normal conditions. During major physiological stress, demand can exceed production—why glutamine is described as conditionally essential.2
Recovery support
A small randomized crossover study found lower perceived soreness and modestly better torque recovery following eccentric exercise with a high-dose glutamine protocol.3
Fuel for intestinal cells
Glutamine is a fuel source for enterocytes. Small exercise studies reported reduced markers of exercise-related intestinal permeability at doses higher than this product’s 5 g serving.4
Immune-cell metabolism
Glutamine participates in lymphocyte proliferation and cytokine production and contributes to macrophage and neutrophil function. This does not mean supplementation prevents illness.2
RESEARCH SPOTLIGHT
What one recovery study actually found.
Sixteen adults completed a double-blind, randomized, placebo-controlled crossover trial after eccentric leg exercise. The chart uses the published group means.3
Research context: This was a small study (n=16). Participants used 0.3 g/kg/day—more than one 5 g serving for most adults. Results cannot be assumed for every person or dose. Broader evidence does not show that glutamine alone reliably increases muscle growth, strength, or athletic performance.1,3

Supplement Facts
QUESTIONS, ANSWERED
Glutamine,
without the hype.
What is L-glutamine?
An amino acid made by the body and found in protein-containing foods. It participates in normal metabolism and serves as fuel for intestinal and immune cells.
When should I take glutamine?
It can be mixed with water or another beverage whenever it fits your routine. Many customers use it after training or on both training and rest days.
Will glutamine build muscle?
Research does not show that glutamine alone reliably increases strength, lean mass, or athletic performance in healthy, well-nourished adults.
Is it flavored or sweetened?
No. It is unflavored and contains no sweeteners. The only listed ingredient is L-glutamine.
Can I mix it with other supplements?
Its neutral taste makes it easy to mix with protein, electrolytes, or another beverage. Ask a healthcare professional if you use medication or have a health condition.
