L-Glutamine (100 caps) - NEW!

L-Glutamine provides 500 mg of free-form L-glutamine per vegetarian capsule — the most abundant free amino acid in human muscle tissue and plasma. Unlike most amino acids, which circulate primarily bound within proteins, glutamine is present in enormous quantities as a free molecule, accounting for approximately 60% of the free amino acid pool in muscle tissue. This concentration reflects glutamine's central role in gastrointestinal integrity, immune cell function, nitrogen transport, and neurotransmitter recycling, and its status as a conditionally essential amino acid during periods of illness, surgery, or physiological stress.

• Supports Gastrointestinal Barrier Integrity – Glutamine is the primary energy source for the rapidly dividing epithelial cells lining the gut wall. These cells consume glutamine preferentially to maintain the structural integrity of the intestinal barrier, which is essential for preventing the passage of bacteria and toxins from the gut lumen into the bloodstream.
• Promotes Healthy Immune Cell Function – Lymphocytes and macrophages rely on glutamine as a major fuel substrate — much as they use glucose — to support proliferation and activation during periods of immune challenge. Adequate glutamine availability is necessary for the immune system to mount and sustain an effective response.
• Supports Neurotransmitter Recycling and Brain Function – Glutamine plays a central role in the glutamate–glutamine cycle in the brain. Glial cells convert released glutamate into glutamine, which is then shuttled back to neurons to replenish the brain's primary excitatory neurotransmitter supply, supporting healthy cognitive signaling.
• Conditionally Essential During Stress and Intense Physical Demand – Under normal conditions, the body synthesizes sufficient glutamine in muscle and lung tissue. During illness, surgery, or prolonged physiological stress, elevated cortisol accelerates muscle protein breakdown and depletes intramuscular glutamine stores — making supplemental free-form glutamine clinically relevant for maintaining nitrogen balance and recovery support.
