About this supplement
Saccharomyces boulardii DBVPG 6763 is a specific strain of the probiotic yeast Saccharomyces boulardii, originally isolated from lychee fruit in Southeast Asia. It is a non-pathogenic, transient, thermophilic yeast that survives gastric acidity and colonizes the intestinal tract without systemic absorption. This particular strain (DBVPG 6763) is deposited in the DBVPG (Industrial Yeasts Collection) and is characterized by its ability to support gastrointestinal health, modulate the gut microbiota, and produce enzymes and compounds that inhibit pathogenic bacteria. Unlike bacterial probiotics, it is unaffected by antibiotics, making it suitable for use during antibiotic therapy. It functions by competing with pathogens for adhesion sites, stimulating immune responses, and producing polyamines that promote intestinal cell growth and repair.

Technical details â–¼
Physical properties
Off-white to tan powder or lyophilized granules. Typically odorless with a slight yeast-like aroma. Soluble in water, forming a suspension. Viable cells are measured in colony-forming units (CFU). Stable at room temperature when dried, but sensitive to moisture and high heat.
How it’s made
Produced via controlled fermentation in sterile bioreactors using specific culture media (often containing sugars, nitrogen sources, vitamins). The yeast biomass is harvested, washed, concentrated, and dried via lyophilization (freeze-drying) or spray-drying to preserve viability. The strain DBVPG 6763 is maintained in culture collections and undergoes quality control for identity, purity, and potency.
