Title and abstract of The nutriceutical bovine colostrum truncates the increase in gut permeability caused by heavy exercise in athletes

Key Takeaway

Bovine colostrum supplementation reduced exercise-induced gut permeability by 80%, potentially protecting against "leaky gut" during intense training.

Summary

This study examined whether bovine colostrum could protect against exercise-induced increases in intestinal permeability (leaky gut).

Results showed that colostrum supplementation prevented the increase in gut permeability typically seen after intense exercise, suggesting a protective effect on gut barrier function.

Methods

  • Randomized placebo-controlled trial
  • Running-based exercise protocol
  • Lactulose/rhamnose permeability test
  • 14 days supplementation

Key Results

  • 80% reduction in exercise-induced gut permeability
  • Maintained gut barrier integrity
  • No GI side effects
  • Benefits seen within 2 weeks

Limitations

  • Small sample size
  • Acute exercise model only
  • Indirect permeability measure
