BioPro Sb 35 DF
Gut Balance & Immune Support
Your gut and your immune system are more connected than most people realize. BioPro Sb 35 DF combines four trusted bacterial strains with Saccharomyces boulardii, a well-researched probiotic yeast specifically studied for supporting gut-based immune function.*

Gastrointestinal-based immune support
Healthy gut bacteria balance support
Bowel regularity support
Resilience during digestive disruption
Broad intestinal ecology support
The link between gut health and immune function isn’t just a talking point — your intestinal lining is one of the largest immune-active surfaces in your body. BioPro Sb 35 DF is built with that connection specifically in mind.
It starts with the same four well-researched bacterial strains found in BioPro 30 DF, then adds Saccharomyces boulardii — a probiotic yeast with one of the strongest research records in the category, studied for its role in supporting healthy immune signaling right where your gut and immune system meet. It’s a different organism entirely from the bacterial strains (a yeast, not a bacterium), which means it works through complementary pathways rather than overlapping with them.*

Key ingredients
Saccharomyces boulardii
Saccharomyces boulardii
Most probiotics are bacteria. S. boulardii is a yeast, which means it works through entirely different mechanisms and isn't affected by antibiotics the way bacterial strains can be. It's been studied in over 30 clinical trials, with documented effects on immune signaling at the gut lining itself.*
HOWARU® Bifidobacterium lactis HN019®
Bifidobacterium animalis subsp. lactis HN019
HN019® is one of the most extensively researched probiotic strains available, with human trials showing measurable improvements in whole-gut transit time and gut function.*
Lactobacillus acidophilus La-14®
Lactobacillus acidophilus La-14
La-14® was selected on its own documented evidence for strong adhesion to intestinal cells — the property that lets a strain establish itself rather than simply pass through.*
Lactobacillus plantarum Lp-115®
Lactiplantibacillus plantarum Lp-115
Lp-115® was selected for its documented ability to survive stomach acid and bile — the two barriers that eliminate most probiotic organisms before they reach the intestine.*
Bifidobacterium longum Bl-05®
Bifidobacterium longum Bl-05
Bl-05® was selected for its documented ability to thrive in the intestinal environment specifically — chosen on individual evidence rather than to pad a strain count.*
