Introduction
If you've ever made bread, you're familiar with yeast - a common type of fungi that ferments sugar and is responsible for the rise in dough. But did you know that yeast can also be a beneficial probiotic for your digestive health?
What are yeast probiotics?
Yeast probiotics are strains of yeast that are beneficial to our gut microbiome. The most common yeast probiotics are Saccharomyces cerevisiae (S. cerevisiae) and Saccharomyces boulardii (S. boulardii).
How do yeast probiotics benefit our health?
Yeast probiotics provide several health benefits, including:
Improved gut health: Yeast probiotics have been shown to increase the number of beneficial bacteria in the gut, which can help improve digestion, boost immunity and reduce inflammation.
Reduced diarrhea: Studies have found that S. boulardii can help reduce diarrhea caused by antibiotics, traveler's diarrhea and other types of diarrhea.
Reduced inflammation: Yeast probiotics may help reduce the production of pro-inflammatory substances in the gut, which can contribute to chronic inflammation and digestive disorders.
Improved gut barrier function: S. boulardii has been shown to improve the integrity of the gut barrier, which can help prevent harmful substances from entering the bloodstream and causing inflammation.
Reduced risk of infections: S. boulardii may help reduce the risk of infections from harmful bacteria, such as Clostridium difficile (C. diff) and candida.
How to get yeast probiotics
You can get yeast probiotics from supplements or fermented foods, such as:
Probiotic supplements: Look for supplements that contain S. cerevisiae or S. boulardii. Follow the dosage instructions carefully.
Kombucha: A fermented tea drink, kombucha contains S. cerevisiae and other probiotic bacteria and yeast.
Sourdough bread: Sourdough bread is made with a natural starter that contains S. cerevisiae and other beneficial bacteria.
Kefir: A fermented milk drink, kefir contains S. cerevisiae and other probiotic bacteria and yeast.
Beer and wine: Beer and wine are fermented with S. cerevisiae and other yeast strains.
Precautions and side effects
While yeast probiotics are generally safe, some people may experience side effects such as gas, bloating and diarrhea. If you're experiencing these symptoms, stop taking the probiotic and consult with your healthcare provider.

People with weakened immune systems, such as those with HIV/AIDS or who are undergoing chemotherapy, should also avoid taking yeast probiotics.
Conclusion
Yeast probiotics can be a great addition to your diet to help improve gut health and reduce the risk of digestive disorders. Before starting any new supplement, it's important to consult with your healthcare provider to ensure that it's safe for you and won't interact with any medications you're currently taking.
