Saccharomyces Boulardii Probiotic – 30 Vegetable Capsules – Swanson

Saccharomyces boulardii is a well-characterised probiotic yeast widely used in nutritional science and food microbiology. Unlike bacterial probiotic strains, this eukaryotic microorganism belongs to the yeast family and demonstrates natural stability across a range of digestive conditions. Each Swanson capsule provides a carefully standardised amount of viable organisms in a vegetable capsule shell suitable for vegetarians. The formulation is designed to support individuals seeking a consistent probiotic yeast supplement as part of a daily wellness routine.

What Is Saccharomyces Boulardii?

Originally isolated in 1923 by French microbiologist Henri Boulard, Saccharomyces boulardii is a specific subtype of Saccharomyces cerevisiae with unique physiological characteristics. It naturally tolerates acidic environments and does not require refrigeration thanks to its yeast structure and resistance to temperature fluctuations. In supplement form, it is standardised as a live microorganism measured in colony forming units (CFU), ensuring consistent viability at the moment of manufacture.

Technical Features – Saccharomyces Boulardii Probiotic (Swanson)

Standardised CFU Content

Each vegetable capsule contains a defined quantity of live Saccharomyces boulardii cells. CFU standardisation ensures that each capsule delivers a consistent count of viable organisms at the time of manufacture, supporting accuracy and reproducibility across batches.

Vegetarian Capsule Format

The probiotic yeast is encapsulated in a vegetable cellulose (HPMC) shell free from animal-derived gelatin. This supports individuals following vegetarian or plant-focused nutritional routines, while also maintaining compatibility with common dietary preferences.

Acid-Resistant Microorganism

Unlike certain probiotic bacteria, Saccharomyces boulardii naturally withstands gastric acidity without the need for enteric coating. Its structural resilience contributes to its stability during storage and its ability to pass through the digestive tract.

Shelf-Stable Formula

The product remains viable at typical room temperatures (15–25°C), eliminating the need for refrigeration under normal storage conditions. This stabilises CFU counts during the labelled shelf life and makes the product convenient for travel and daily use.

Composition per Capsule

Exact CFU numbers and excipient details may vary slightly depending on the batch. Refer to the Swanson packaging for final verified values.

• Main ingredient: Saccharomyces boulardii (live probiotic yeast, CFU-standardised)
• Capsule shell: Hydroxypropyl methylcellulose (vegetable cellulose)
• Other ingredients: May include rice flour, microcrystalline cellulose, or anti-caking agents
• Free from: Artificial colours, preservatives, gluten, lactose

Scientific Context – Yeast-Based Probiotics

Saccharomyces boulardii is distinct from bacterial probiotics due to its eukaryotic cell structure, genetic characteristics, and environmental tolerances. This yeast organism is extensively researched in microbiology, food science, and digestive ecology. Its ability to withstand stomach acidity, tolerate bile, and retain viability without refrigeration has contributed to its wide use in nutritional formulations.

Investigative Research Areas

• Yeast behaviour within the digestive tract
• Interactions between Saccharomyces species and gut microbial communities
• Stability of eukaryotic cells during manufacturing, encapsulation, and storage
• Comparative survivability of yeast versus bacterial probiotics
• CFU standardisation techniques for yeast-based supplements
• Role of yeast in fermentation-derived micronutrients and digestive dynamics

Documented Usage Contexts

Probiotic yeast is used across a variety of nutritional scenarios. Typical usage contexts include:

• Daily supplementation for general gut microbiota support
• Inclusion alongside bacterial probiotics as part of multi-strain routines
• Vegetarian and plant-focused supplement programmes
• Use during travel or routine schedule changes due to its shelf stability
• Integration into digestive wellness regimens
• Temporary routines based on lifestyle or diet changes
