Saccharomyces BoulardiiUpdated 2 days ago
What is Saccharomyces boulardii—and why is it in Biotic⁺?
S. boulardii is a unique, non-pathogenic yeast probiotic with a long history of safe use. It was first isolated in Southeast Asia from lychee and mangosteen fruit—after locals noticed it helped relieve cholera symptoms when added to fruit tea.
🤔 What benefits does S. boulardii offer?
This powerful yeast strain is backed by research showing it can:
Support gut balance, especially during digestive disturbances (Riaz et al., 2012)
Help to balance the gut microbiota, supporting healthy intestinal barrier function (Gaisawat et al., 2019)
Support recovery from gut discomfort, such as traveller’s diarrhoea (McFarland et al., 2010)
🤔 Why use this specific probiotic yeast?
Distinct from bacterial probiotics—it won’t compete with your gut’s natural bacteria
Proven safe in both adults and children, even during antibiotics or tummy upsets
Historically used in tropical regions, before modern medicine confirmed its benefits
🤔 How does it work in your body?
Arrives alive in your gut without interfering with gut bacteria
Binds to gut surfaces, helping prevent the growth of harmful microbes
Supports your immune system’s presence in the digestive tract
Helps restore digestive balance during times of challenge
🤔 Why include it in Biotic⁺?
We included S. boulardii to broaden Biotic⁺'s benefits—to support digestive resilience, gut-immune strength, and recovery from occasional stressors—without overlapping with our bacterial strains.
