Product Description

Introducing our gentle yeast-based probiotics, starring the beneficial yeast strain, Saccharomyces boulardii. To help avoid common antibiotic side effects like diarrhea, fatigue and brain fog.* 

Folks with Clostridium difficile (C. diff), candida, yeast infections and mild skin rashes also use saccharomyces probiotics, as guided by a practitioner.* 

Smidge® Yeastbiotic is pure and simple. 

Dairy and gluten-free.
And free of common allergens.

Dosage Directions

Always start with a smidge! Take 1 capsule twice daily with food until the bottle is finished (See “low and slow” note below), or as directed by a certified healthcare practitioner. May be taken before, during or immediately following a course of antibiotics under the advice of your doctor.* This is not intended to be a maintenance probiotic.

Warning: Not recommended for severely immunocompromised individuals or those with central venous catheters.

Start low and slow: Smidge® supplements are premium, pure and potent. Therefore, it's critically important to start slowly, with a lower dosage than recommended. For example, a minimal dose every other day, or even once a week, until you can determine how the supplement affects your body and what feels right for you.

How to take: You can take your saccharomyces probiotic along with your antibiotics, as guided by your healthcare practitioner. We recommend taking it a couple of hours apart from your antibiotic dose. If you've finished a round of antibiotics and seek support, you can follow-up with Yeastbiotic.

Additionally, and equally as important, abstaining from sugary foods that feed pathogenic yeast increases its efficacy (customers often consume ancestral diets such as SCD or paleo), which include essential fatty acids.

Storage

Store in a cool, dry area. Refrigerate for long-term storage.

Sourcing and crafting Yeastbiotic

We meticulously source the Saccharomyces boulardii in Yeastbiotic to ensure purity, quality and effectiveness. This probiotic yeast — known for its ability to target pathogens in the gut and resilience through digestion — is derived from carefully selected strains initially found in nature, such as mangosteen peel and lychee fruit. While its origins grow from the earth, the strain is from a trusted bank to ensure a clean, controlled foundation.

We cultivate our isolated strain of S. boulardii with precision and care in a nutrient-rich environment that maximizes its growth. Then, it’s gently freeze-dried for potency. Each small batch undergoes thorough testing for viability.

For antibiotics, candida issues, and more*

Each capsule contains pure S. boulardii, well-known for balancing candida issues. (Some supplement manufacturers substitute brewer's or baker's yeast for S. boulardii. Not Smidge®!) 

You can take this saccharomyces boulardii probiotic supplement with your antibiotics (as guided by your healthcare provider), as it may not compromise the potency or effectiveness of the antibiotics.* So both can do their crucial jobs while you're on the mend.* 

And even if you're not on antibiotics, Smidge® Yeastbiotic can nourish your digestive system. Our customers tell us they often take it while following natural interventions, such as special diets for candida or other mild fungal overgrowths.* 

How does S. bouldardii work in the body?

Antibiotics will only attack bacteria, not yeast. People often have issues when on antibiotics, as they wipe out "good bacteria." And candida that has been lying dormant will take over along with an array of other unpleasant side effects. 

S. boulardii, the friendly yeast strain found in Smidge® Yeastbiotic, may prevent and treat diarrhea caused by antibiotics.* It does this by gently crowding out troublesome microbes in the gut and augmenting the intestinal absorption of D-glucose and sodium, which may enhance the uptake of water and electrolytes during occasional diarrhea.* 

S. boulardii may help with the fatigue and brain fog often caused by antibiotics, too. 

More S. boulardii health benefits

S. boulardii can do an enormous amount of work to keep you feeling good.* 

Studies show S. boulardii: 

  • Supports intestinal health and the microbiome* 
  • Preserves intestinal barrier function* 
  • Supports the immune system* 
  • May inhibit pathogenic yeast related to candida issues* 
  • May have broad antimicrobial activities against Clostridium difficile (C. diff), E. coli and other gastrointestinal pathogens* 
  • Avoids nausea related to low stomach acid, and may ease mild acid reflux* 

That's why many doctors and practitioners turn to this helpful yeast when antibiotics have thrown everything out of whack.* 

S. boulardii, candida and women’s health

Because S. boulardii has been shown to inhibit pathogenic yeast related to candida issues, women may take it to balance pH levels related to yeast infections and bacterial vaginosis.* And, it may help with mild skin issues related to candida, like rashes and acne caused by yeast sensitivity.* 

 

Yeastbiotic while traveling

Yeastbiotic is also fantastic for travel, because it may keep some pathogens out of the gut, helping to stave off travelers’ diarrhea.* It may also help avoid an upset stomach and maintain regularity while on the go and experiencing different food and water.*

Frequently Asked Questions

Why take Smidge® Yeastbiotic?

There are many reasons. Here are just a few to run by a certified healthcare practitioner: 

  • You may be taking antibiotics and want to avoid any bothersome side effects like diarrhea, yeast issues, fatigue and brain fog.* 
  • You may be searching for a solution to mild, periodic IBS and other inflammatory bowel conditions* 
  • You received a recommendation from a trusted practitioner for issues like candida or C. diff.* 
  • You want to support your digestive health.* 

Is Yeastbiotic free of all common allergens?

It's free of the following common allergens: does not include milk/casein, eggs, fish, shellfish, tree nuts, corn, peanuts, wheat/gluten or soybeans. 

Is Yeastbiotic SCD compliant?

Yeastbiotic is SCD compliant and can be used to treat diarrhea or other antibiotic-related problems stemming from systemic yeast overgrowth, under the guidance of a qualified healthcare practitioner.*

Why are there flecks of brown in my yeast probiotic capsule?

You will see that your Yeastbiotic capsules have small flecks of brown in them. The friendly yeast strain is the brown color, while the cellulose (the benign filler necessary for encapsulation) is white. Please know the color variation is entirely normal and a characteristic of the formula. 

Can I take Yeastbiotic along with other Smidge® probiotics?

Sure thing. Yeastbiotic works great with our probiotics. Together, they can help balance the bacteria in your digestive system affected by antibiotics. 

At the same time, therapeutic probiotics like our Sensitive Probiotic may intensify Yeastbiotic’s effectiveness. So, if you’re experiencing discomfort due to excessive yeast die-off, lower your Yeastbiotic dose. You can further lower by pulling apart the capsule and taking a portion of the powder (the powder will appear white with brown specs).  

Can I take Smidge® Yeastbiotic as my everyday probiotic?

We recommend our customers take this one as needed (and until the bottle is finished), as it works better in bursts rather than long-term. This is because pathogenic yeast is very resilient and can become resistant to particular strains or even antifungal treatments.* 

Equally as important, this supplement is most effective when taken while abstaining from sugary foods that feed pathogenic yeast (i.e. cookies + yeast = no bueno). Many of our customers consume ancestral diets (such as SCD or paleo) that include essential fatty acids, and take a quality digestive enzyme

 

Where are the ingredients in Smidge® Yeastbiotic sourced and where is the supplement made?

The strains in our Yeastbiotic capsules are sourced in the U.S., as is the production of the final product :) 

Will Yeastbiotic affect the potency of my antibiotics?

Yeastbiotic lets your antibiotics do their thing. You can take it while taking antibiotics (under your doctor’s advice), because antibiotics should not interfere with S. boulardii's potency or effectiveness and vice versa.* 

Won't my probiotics be enough to keep the good bacteria in my intestines going while on antibiotics?

Probiotics have become the go-to ally for getting your digestive system back on track and maintaining good health. But when you're taking antibiotics, these helpful bacteria can be helpless. Antibiotics wipe out the good and bad bacteria indiscriminately. Yet antibiotics will only attack bacteria, not yeast. So you can take Smidge® Yeastbiotic while you're taking antibiotics (under the advice of your doctor), because antibiotics don't interfere with S. boulardii's potency or effectiveness and vice versa.* 

Is this a probiotic or yeast?

Great question! Smidge® Yeastbiotic is a yeast that happens to function like a probiotic in the body (so it's both!). 

How was S. boulardii discovered?

History lesson! The French scientist Henry Boulard first discovered S. boulardii in 1920 after observing that certain locals in Indonesia were not succumbing to an outbreak of cholera. The healthier locals drank tea made from the skins of lychee and mangosteen, from which Boulard was able to isolate S. boulardii as the protective yeast. The strain has been named after him ever since its discovery. 

What kind of diet works best on Smidge® Yeastbiotic?

We recommend working with your diet and abstaining from sugar or other processed foods that feed yeast and other pathogens. Customers often consume ancestral diets (such as SCD or paleo) that include essential fatty acids.
