Sometimes a course of antibiotics can do as much harm as good. It can comfortably clear a bacterial infection, but it can also wipe out a broad spectrum of good bacteria from our gut. If bacterial die-off occurs, other opportunistic microbes may proliferate with negative consequences. These microbes include candida or yeast.

As a result, you or your customers may feel the onset of various symptoms, which may include brain fog, neurological issues, digestive stress, skin rashes, joint pain or candida overgrowth. We have a powerful preventative solution that can be taken alongside or after antibiotics: Yeastbiotic. This product contains the beneficial non-bacterial microorganism, Saccharomyces boulardii, which has been shown to hold space to allow the gut microbiome to rebalance.

What is Yeastbiotic?

Smidge Yeastbiotic contains Saccharomyces boulardii which was initially discovered by French microbiologist Henri Boulard in 1920. His research showed that people who regularly consumed a decoction of lychee skins and mangosteen fruits helped strengthen their digestive system. [2] Although most probiotics are bacterial-based, Yeastbiotic can fight off infections and minimise unwanted symptoms.

The S. boulardii strain has many properties that underlie its success as a probiotic, including an optimal growth temperature of 37°C (the same as our bodies), resilience to the gastric environment and viability at low pH (perfect for ensuring maximum effect in our gut). [1]

What are the benefits of Yeastbiotic?

The S. boulardii strain contains many probiotic features. It can improve gut barrier function so that valuable nutrients can be absorbed into the bloodstream. [1] In cases of irritable bowel disease (IBD) and irritable bowel syndrome (IBS) inflammation can cause the gut lining to swell, resulting in severe pain or loose motions. S. boulardii can help restore the gut lining by protecting the tight junctions between the epithelial cells and reducing their intercellular space. [3]

Yeastbiotic can help establish a healthy microbiome through the principle of pathogen competitive exclusion. [1] S. boulardii may flourish under the conditions of antibiotics and may colonise while outcompeting populations of pathogenic bacteria in the gastrointestinal tract. [4]

Yeastbiotic can increase the production of antimicrobial peptides (AMP), which are small peptides that play an essential role in the innate immune system. AMPs have a wide range of inhibitory effects against pathological bacteria, fungi, parasites and viruses. [5]

Macrophages are specialised immune cells that help clean up debris, activate host defense, trigger tissue repair, and maintain homeostasis. They can be targeted for immunomodulation by S. boulardii and increase macrophage maturation and efficiency. [6]

With 3+ billion CFUs per capsule, you can rest assured that you are getting the best on the market.

Yeastbiotic can help people with...

• Candida overgrowth 

• Yeast infections 

• Occasional diarrhea issues 

• Weakened digestive system 

• As a solution for mild, periodic IBS and other inflammatory bowel conditions 

• Anyone wanting to avoid antibiotic side effects like diarrhea, yeast issues, fatigue, and brain fog

How can I get the best value from my Yeastbiotic? 

What you eat directly impacts the delicate microbiome balance of the gut. Yeastbiotic is most effective when taken while abstaining from sugary foods that feed pathogenic yeast. Help the hard-working S. boulardii species by eating a balanced diet of organic vegetables, nuts, seeds, and high-quality fermented foods.

If you experience issues with yeast die-off, such as muscle pain, headaches, anxiety, hyperventilation, or a sore throat, break open a Yeastbiotic capsule and sprinkle half a cap on your food. It's important to know Candida die-off is not a chronic illness or a new infection. It is a temporary syndrome. [7]

Can I use Yeastbiotic with other probiotics?

Yes! Smidge Yeastbiotic can be used at the same time as other probiotics. We recommend pairing it with Sensitive Probiotic to help intensify Yeastbiotic's effectiveness.
