Supports These Goals

Why you'll love it

Your gut lining replaces itself every 3-5 days, and it burns through glutamine faster than any other fuel to make that happen. The cells lining your intestines (enterocytes) rely so heavily on glutamine that when levels drop — from stress, intense exercise, or illness — gut permeability can increase, allowing unwanted molecules to slip through the barrier.

This is why glutamine has become a cornerstone of gut health protocols. Research shows it supports the tight junctions between intestinal cells, promotes healthy gut barrier function, and supports repair of damaged intestinal tissue. If you've ever dealt with digestive issues after intense training or during stressful periods, low glutamine availability may be a contributing factor.

Glutamine is also critical for immune function. Your immune cells — particularly lymphocytes and macrophages — consume glutamine at rates comparable to glucose. During intense exercise or physical stress, glutamine demand can exceed supply, potentially leaving your immune system compromised. Supplementation helps maintain the reserve your immune system needs to stay sharp.

How much do I really need?

Take one 750mg capsule daily. For gut health support, take on an empty stomach (first thing in the morning or between meals). For exercise recovery, take immediately after training. Glutamine is stable and well-tolerated at this dose.
