PRL Premier Glutamine 100 Capsules – Key Amino Acid for Gut, Immune & Muscle Recovery Support

PRL (Premier Research Labs) Premier Glutamine provides L-glutamine — the most abundant amino acid in the body and an essential fuel source for intestinal cells and immune cells. Glutamine is conditionally essential during stress, illness, intense training, and gut injury, where demand outstrips the body's production capacity. This formula supports intestinal mucosa integrity, immune function, muscle recovery, and protein synthesis.

• L-glutamine — key amino acid for gut and immune health
• Supports intestinal mucosa integrity and gut lining repair
• Fuels immune cell activity and protein synthesis
• Supports muscle recovery after intense exercise
• 100 capsules — PRL quality

Frequently Asked Questions

What is glutamine used for?

Glutamine is used for gut health (leaky gut, IBS, Crohn's, post-antibiotic gut repair), immune support, muscle recovery after intense exercise, and supporting the body during stress or illness. It is the primary energy source for intestinal epithelial cells and lymphocytes.

Who benefits most from glutamine supplementation?

People with leaky gut or intestinal permeability issues, athletes doing high-intensity training, people recovering from illness or surgery, those with IBS or inflammatory bowel conditions, and anyone under significant physical or emotional stress benefit most from glutamine.

Does glutamine help with leaky gut?

Yes. Glutamine is essential for maintaining tight junction integrity in the intestinal wall. Supplemental glutamine has been shown to reduce intestinal permeability, support mucosa repair, and improve gut barrier function — making it a cornerstone of leaky gut protocols.

When should I take glutamine?

For gut health, take on an empty stomach 20–30 minutes before meals. For muscle recovery, take after training. For immune support, take with food. Some people split the dose morning and evening for consistent blood levels throughout the day.

Is L-glutamine safe to take long-term?

L-glutamine is generally considered safe for long-term use at recommended doses. Very high doses (above 40g daily) may cause gastrointestinal discomfort. People with liver or kidney conditions should consult their doctor before taking amino acid supplements.
