Essential-Biotic® Saccharomyces Boulardii 60 capsules Allergy Research Group
$28.89
Overview
Essential-Biotic® Saccharomyces Boulardii 60 capsules is a targeted probiotic yeast supplement designed to support gut flora balance, healthy bowel function, gastrointestinal resilience, and immune health. Each 3-capsule serving provides 9 billion CFU of Saccharomyces boulardii (CNCM I-3799), a non-colonizing, acid-resistant probiotic yeast known for its ability to support digestive balance without permanently altering the resident microbiota.
Unlike bacterial probiotics, Saccharomyces boulardii is a transitory microorganism that passes through the GI tract and is eliminated after supplementation stops. This makes it a practical option for those looking for a research-backed Saccharomyces boulardii supplement for gut and immune support, including during periods when microbial balance and bowel regularity need extra support.
Key Benefits
- Provides 9 billion CFU of Saccharomyces boulardii per serving
- Supports healthy gut flora balance and gastrointestinal function
- Promotes healthy bowel movements and digestive resilience
- Supports gut barrier and immune function
- Features an acid-resistant, non-colonizing probiotic yeast
- Suitable for short-term or longer-term use under practitioner guidance

Other Ingredients: Hydroxypropyl methylcellulose, microcrystalline cellulose, silicon dioxide, stearic acid.
Ingredient Breakdown
| Ingredient | Purpose in the Formula |
|---|---|
| Saccharomyces boulardii (CNCM I-3799) | Probiotic yeast used to support bowel balance, microbial resilience, and immune function in the GI tract |
How It Works
Saccharomyces boulardii is different from standard bacterial probiotics. It is a probiotic yeast that survives stomach acid well and moves through the digestive tract without colonizing it permanently. This gives it a unique role in supporting the intestinal environment while remaining temporary in the gut.
The strain used here, CNCM I-3799, is included at a clinically relevant level and is intended to support healthy bowel motility, microbial balance, and gut barrier function. According to the manufacturer, Saccharomyces boulardii also supports secretory IgA and short-chain fatty acid production, making it relevant not only for digestive comfort but also for broader gut-associated immune support.
Because it is acid-resistant, non-colonizing, and well tolerated, this yeast-based probiotic can be a strong option for individuals looking for a GI support supplement with Saccharomyces boulardii rather than a conventional multi-strain bacterial probiotic.
Suggested Use
As a dietary supplement, take 3 capsules daily between meals, or as directed by a healthcare practitioner.
FAQ
What does Essential-Biotic® Saccharomyces Boulardii support?
It is designed to support healthy gut flora balance, bowel function, gastrointestinal resilience, and immune health.

Each 3-capsule serving provides 450 mg of Saccharomyces boulardii (CNCM I-3799), equal to 9 billion CFU.
How is Saccharomyces boulardii different from bacterial probiotics?
It is a probiotic yeast, not a bacterial strain. It is acid-resistant, does not permanently colonize the gut, and is eliminated after supplementation is discontinued.
Who might consider this product?
It may be useful for individuals looking for targeted GI and immune support, especially when digestive balance and bowel regularity need extra support.
How should it be taken?
Take 3 capsules daily between meals, or as directed by a healthcare practitioner.
