Introducing our yeast-based probiotics, starring the beneficial yeast strain, Saccharomyces boulardii. For when you want to avoid the icky common side effects of antibiotics, like diarrhea, fatigue and brain fog.* Folks with Clostridium difficile (C. diff) and candida also use saccharomyces probiotics as guided by a practitioner.*

Each capsule contains pure S. boulardii, which is 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.*

  • May ease antibiotic side effects*
  • Supports a healthy microbiome*
  • Non-GMO
  • For occasional diarrhea & yeast issues*
  • Can be taken during and after antibiotics
  • Free of common allergens

What does Yeastbiotic do?

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.

But that's just the beginning. 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*

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


Always start with a smidge! Take 1 capsule daily (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.*

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. This supplement is most effective when taken in two to three-week increments, followed by a break of one to two weeks. 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.

Shipping: We use a combination of shipping services with tracking to best serve our customers. Our goal is to get your package to you in the most efficient manner using the most cost effective method.

Smidge™ probiotics ship Monday and Tuesday using Australia Express or DHL Express services.

Smidge™ probiotics contain active freeze-dried bacteria, versus live cultures. Unlike live cultures, which can be destroyed in transit by heat, freeze-dried bacteria hold up well in warm weather, as they remain intact and stable with all of their beneficial properties. This means your probiotics will arrive in optimal condition. (Then once you receive your package, you can put them in the fridge.)
