Synergy
What is happening. L-glutamine and the probiotic yeast Saccharomyces boulardii are often combined for gut barrier and digestive support, acting through complementary mucosal mechanisms.
Mechanism. L-glutamine fuels enterocytes and supports tight junctions, while S. boulardii enhances brush-border enzyme activity, trophic polyamine production, and short-chain fatty acid availability that nourish the mucosa.
Recommendation. Reasonable to combine for intestinal support. No timing separation needed.
