Reorder & review

Over 90% of Medibro subscribers are still on the same product at 3 months — the clearest signal a supplement is working.

Glutamine is conditionally essential under intense exercise — your body's demand exceeds production. It's the primary fuel source for intestinal epithelial cells, supporting gut barrier integrity. Athletes under heavy training loads may benefit from supplementation for both recovery and gut health.

    Pure, no additives

    Just glutamine, nothing else. Mixes well in water or protein shakes. The intestinal lining uses glutamine as primary fuel — this is well-established science. Noticeably less gut distress during hard training blocks.

  • ★★★★★Hannah O.

    Essential for IBS recovery

    Pure powder with no additives. Dissolves easily in water or a protein shake. Unflavoured so very versatile.

    IBS improvement

    IBS-D for years. Gastroenterologist suggested L-glutamine alongside dietary modifications. Symptoms improved by about 60% after 6 weeks. Not a cure but a significant improvement in daily function.

    Post-workout recovery faster

    Glutamine is the most abundant amino acid in muscle tissue and depletes rapidly during intense training. Adding 5g post-workout and muscle soreness is significantly reduced. Good pure powder.
