Gut barrier support
Randomised trial data has shown glutamine supplementation can lower markers associated with intestinal permeability and circulating endotoxin exposure, making it relevant when barrier integrity is the focus.
Supplements
Precision Glutamine
A targeted gut companion that helps support the lining itself, not just the microbiome around it.
Your intestinal lining is one of the fastest-turnover tissues in the body, rebuilding constantly to keep the barrier between the gut and bloodstream intact. That job requires fuel, and glutamine is one of the primary fuels those barrier cells rely on.
Who it's for
For people prioritising digestive resilience, gut lining support, or a more complete companion to Precision Gut when they want a deeper gut-focused protocol.

The Story
Why this formula was built this way.
When glutamine availability is adequate, the cells lining the gut can better maintain tight junctions and keep the barrier functioning the way it should. When demand rises during stress, illness, heavy training, or ongoing inflammatory load, support can become more relevant.
Precision Glutamine is designed to pair with Precision Gut and Precision Fibre so the protocol supports the microbiome, the prebiotic environment, and the gut lining itself from complementary angles.
The Evidence
Why this formula made the cut.
Educational summary. Not a substitute for personalised medical advice.
Enterocyte fuel
Glutamine is a major metabolic fuel source for intestinal cells and provides building blocks used during rapid epithelial turnover, which is one reason it is so central to gut-lining support strategies.
Synergy with probiotics and fibre
Glutamine complements the probiotic and prebiotic sides of a gut protocol by addressing the barrier tissue directly, rather than only the microbes living alongside it.
Stress and training demand
Physiological stress and heavy exercise increase glutamine demand. In those settings, supplementation may help support the gut barrier during periods when it is under more strain.
Important Considerations
A few things to know before you start.
Population guidance
2If you have significant liver disease, cirrhosis, or a history of hepatic encephalopathy, review glutamine with your healthcare provider before use.
If you have an active malignancy or are undergoing cancer treatment, consult your oncology team before adding glutamine supplementation.
