The Claim

Oral glutamine supplementation at 30 g/day during radiochemotherapy for advanced esophageal cancer is associated with reduced gut barrier permeability, as measured by lower urinary excretion of phenolsulfonphthalein, compared to no supplementation.

In plain English

In patients with advanced esophageal cancer undergoing radiochemotherapy, taking 30 grams of glutamine daily by mouth is associated with lower levels of phenolsulfonphthalein in urine, indicating reduced gut barrier permeability compared to not taking glutamine.

Oral glutamine supplementation at 30 g/day during radiochemotherapy for advanced esophageal cancer is associated with reduced gut barrier permeability, as measured by lower urinary excretion of phenolsulfonphthalein, compared to no supplementation.

Why this might work

Glutamine from supplements is absorbed and used by gut lining cells as fuel to stay healthy and repair themselves. It also helps make a molecule that neutralizes damage from cancer treatment. This keeps the tight seals between gut cells intact, so harmful substances cannot leak into the bloodstream and appear in urine.

  1. Study: Effects of glutamine supplements and radiochemotherapy on systemic immune and gut barrier function in patients with advanced esophageal cancer.

    Taking 30 grams of glutamine daily during cancer treatment helped keep the gut lining intact, so fewer harmful substances leaked into the urine — meaning the gut stayed healthier than in patients who didn’t take glutamine.
