Gut health is the foundation of overall wellness. Your digestive system houses trillions of microorganisms that affect everything from immunity to energy levels to mood. Our Vitadefence Saccharomyces Multi combines Saccharomyces Boulardii—a beneficial probiotic yeast—with vitamin D3, biotin, olive leaf extract, and bamboo silica to create a comprehensive formula supporting immune function, gut health, and overall vitality.
Saccharomyces Boulardii is a probiotic yeast—not bacteria—that has been studied extensively since its discovery in the 1920s. At 5 billion CFU (Colony Forming Units) per capsule, our formula provides a substantial dose of this unique probiotic.
Unlike bacterial probiotics, Saccharomyces Boulardii is naturally resistant to stomach acid and antibiotics, making it particularly valuable during and after antibiotic treatment. This hardy yeast survives passage through the digestive tract and supports beneficial gut flora.
Originally isolated from lychee and mangosteen fruits by French scientist Henri Boulard, Saccharomyces Boulardii has been used for decades in Europe and gained popularity worldwide for digestive and immune support.
Important note: The Saccharomyces boulardii does not originate from the UK.
At 2.5μg (100iu) per capsule (50% NRV), vitamin D provides foundational immune support that complements the probiotic benefits.
At 8μg per capsule (16% NRV), biotin supports the health of mucous membranes throughout the body, including the gut lining.

This focused formula combines the power of beneficial yeast with immune-supporting vitamins and complementary botanicals.
This probiotic yeast stands out from bacterial probiotics in several ways:
Antibiotic Resistant: Unlike bacterial probiotics which are killed by antibiotics, S. Boulardii survives antibiotic treatment, making it ideal for supporting gut health during and after antibiotic courses.
Acid Stable: Naturally resistant to stomach acid, ensuring more organisms reach the intestines alive.
Temporary Colonizer: Doesn't permanently colonize the gut but provides benefits during its passage through the digestive system, typically clearing within days of stopping supplementation.
Well-Researched: Extensively studied for digestive comfort, gut microbiome support, and immune function.
Vitamin D's role in immune function is well-established. The gut contains significant immune tissue, and adequate vitamin D supports optimal immune response. The vegan form (from lichen or algae) provides the same cholecalciferol your body produces from sunlight.
Biotin's contribution to the maintenance of normal mucous membranes is particularly relevant for gut health. The intestinal lining is a mucous membrane, and biotin supports its integrity and function.
Beyond gut health, biotin also supports energy metabolism, helping your body convert food into usable energy.
Olive leaf (Olea Europaea) has been used traditionally in Mediterranean cultures. The standardized extract ensures consistent oleuropein content—the key active compound studied for various properties including potential effects on microbiome balance.
Bamboo provides natural silica, supporting connective tissue health. While the amount is modest, it complements the overall formula's approach to supporting structural health alongside gut wellness.
Dosage: Take 1 capsule, 1 to 3 times per day before meals or as advised.
Maximum: Up to 6 capsules per day.
Timing: Before meals optimizes probiotic survival and colonization potential.
Flexible Dosing:
Do not exceed the recommended daily intake.
Saccharomyces Boulardii's antibiotic resistance makes it uniquely valuable during antibiotic treatment. While antibiotics kill harmful bacteria, they also destroy beneficial gut flora. S. Boulardii survives the antibiotics and helps maintain gut balance.
The probiotic yeast has been studied for supporting digestive comfort and normal bowel function.
Vitamin D contributes to normal immune function, and the gut houses approximately 70% of your immune system. Supporting gut health supports immune health.
S. Boulardii has been popular among travelers for supporting digestive comfort during travel, particularly to areas with different bacterial environments.
Maintaining a balanced gut microbiome supports overall health. S. Boulardii provides different benefits than bacterial probiotics, offering diversity in gut support.
Food supplements should not be used as a substitute for a varied diet and healthy lifestyle.
Consult your doctor before taking any food supplement or changing your diet.

What's the difference between S. Boulardii and regular probiotics? S. Boulardii is a yeast, not bacteria. It's naturally resistant to antibiotics and stomach acid, making it particularly useful during antibiotic treatment and for those with sensitive digestive systems.
Can I take this with antibiotics? Yes! This is one of S. Boulardii's key advantages—it survives antibiotic treatment, unlike bacterial probiotics which are destroyed by antibiotics.
Should I refrigerate this? No. S. Boulardii is shelf-stable and doesn't require refrigeration, unlike many bacterial probiotics.
How long until it works? Some people notice digestive benefits within a few days. For immune support and gut microbiome benefits, consistent use over several weeks is typically recommended.
Can I take this with bacterial probiotics? Yes. S. Boulardii can complement bacterial probiotics, providing diversity in gut support.
Will this permanently colonize my gut? No. S. Boulardii is a transient organism that provides benefits during its passage but doesn't permanently colonize. Benefits typically diminish within days of stopping supplementation.
Is this safe for children? This product is formulated for adults. Consult a pediatrician before giving any probiotics to children.
Can I take this if I'm on a yeast-free diet? S. Boulardii is a beneficial yeast, different from Candida and other problematic yeasts. However, if you're on a yeast-free diet for medical reasons, consult your healthcare provider.
Why is the vitamin D dose relatively low (50% NRV)? This provides foundational support that complements the probiotic. You may take additional vitamin D if needed for your individual requirements.
Does this need to be taken before meals? It's recommended but not absolutely required. Taking before meals may optimize probiotic survival and activity.
How many CFU do I need? 5 billion CFU per capsule is a meaningful therapeutic dose. You can take 1-6 capsules daily depending on your needs, providing 5-30 billion CFU.

Several factors distinguish our Saccharomyces Multi:
Bacterial Probiotics (Lactobacillus, Bifidobacterium):
Probiotic Yeast (S. Boulardii):
Both types are valuable, and many people benefit from using both for comprehensive gut support.
Approximately 70% of your immune system resides in your gut. The gut-associated lymphoid tissue (GALT) contains immune cells that interact with gut microbiota, food particles, and potential pathogens.
A healthy gut microbiome:
By supporting gut health with S. Boulardii and complementary nutrients, you're supporting your immune function from the ground up.
Whether you're taking antibiotics and need gut protection, experiencing occasional digestive discomfort, seeking immune support, preparing for travel, or simply wanting to maintain a healthy gut microbiome, our Saccharomyces Multi offers a unique probiotic approach.
The combination of antibiotic-resistant S. Boulardii, immune-supporting vitamin D, mucous membrane-supporting biotin, and complementary botanicals creates a focused formula for comprehensive gut and immune wellness.
Consistent use, combined with a gut-friendly diet and healthy lifestyle, provides the foundation for optimal digestive and immune health.
