Review: A total gut health essential! - This S.Boulardii from Klaire Labs has become a must-have in our home! One of the best things about it is that it's resistant to antibiotics, so you can safely take it during antibiotic treatments to help protect your gut and that’s exactly what we’ve been doing. It’s gentle, effective, and I’ve noticed a big difference in how our digestion holds up, especially when dealing with medications. I love how high-quality and reliable Klaire Labs products are this one is no exception.
Review: Highly Recommend! - Excellent product! Mold sensitivity was triggered a few weeks ago. My doctor’s homeopathics addressed the mold but not so much the mycotoxins they release and my skin was giving me fits. S. Boulardii really helped with the skin pain. Highly recommend !

## Features

- Comprehensive Digestive & Immune Support - Saccharomyces boulardii is a unique probiotic yeast that promotes digestive balance, enhances bowel function, and helps stimulate the immune system.*
- Hearty, Acid-Resistant Strains - The S boulardii probiotic is an acid-resistant, temperature-tolerant organism unaffected by antibiotics and distinct from brewer’s yeast or Candida species, making it a reliable option for digestive support during times of microbial disruption.*
- Supports Healthy Bowel Transit – Clinical studies show S. boulardii contributes to healthy intestinal function and promotes optimal bowel regularity by improving transit time and encouraging the production of nourishing short-chain fatty acids.*
- Intestinal & Immune Support - Saccharomyces boulardii probiotics can help enhance intestinal immunity by increasing secretory IgA levels and stimulating crypt cell immunoglobulin receptors, meaning they can help reinforce the body’s natural defenses at the gut level.*
- Klaire Labs is Now SFI Health - Klaire Labs has been part of the SFI Health family for many years leading the way in efficacy, safety, quality, and trusted by healthcare practitioners. While we might be changing the way things look, rest assured that our formulations and probiotics for digestive health remain the same.
