01
L-GlutamineModerate
82% match
Glutamine is the primary fuel for enterocytes and small trials show it can blunt the rise in intestinal permeability triggered by prolonged or heat-stressed exercise.
SuggestedPure L-glutamine powder
02
ProbioticsModerate
76% match
Multi-strain probiotics taken for several weeks before competition have reduced GI symptom severity and lowered markers of exercise-induced gut barrier disruption in endurance athletes.
SuggestedMulti-strain capsule taken daily during a 4 to 12 week loading period
03
ColostrumModerate
71% match
Bovine colostrum supplies growth factors and immunoglobulins that have reduced exercise-induced increases in intestinal permeability (lactulose/rhamnose) in several controlled studies.
SuggestedBovine colostrum powder, around 20 to 60 g daily
04
Saccharomyces BoulardiiLimited
60% match
This non-colonizing yeast supports gut barrier integrity and can help normalize bowel transit, which may ease exertional urgency and diarrhea.
SuggestedSaccharomyces boulardii capsules
05
Zinc CarnosineLimited
55% match
Zinc carnosine has been shown to support intestinal mucosal integrity and reduce the gut permeability seen after strenuous exertion in small studies.
SuggestedZinc-L-carnosine, around 75 mg daily
06
QuercetinLimited
45% match
Quercetin's anti-inflammatory and barrier-stabilizing actions are proposed to modestly limit splanchnic-ischemia-driven gut disruption during long efforts.
SuggestedQuercetin phytosome or quercetin with vitamin C
