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.

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 !

Helps
I get chronic yeast infections. I've tried going off sugar completely but that didn't help the issue so I must have candida overgrowth. Even with a good diet that's hard to get rid of. BUT I didn't get an infection last month taking this so I'm gonna stick to it.

The most important strain
Here’s a positive review for Klaire Labs SFI Health Saccharomyces Boulardii Probiotics: --- Klaire Labs Saccharomyces Boulardii Probiotics have been a fantastic addition to my daily routine. After taking these probiotics for a few weeks, I've noticed a significant improvement in my digestive health and overall comfort. They’re gentle yet effective, especially helpful during times when my gut feels off balance, like when traveling or after antibiotics. The capsules are easy to swallow, and I love that they don’t need to be refrigerated, which makes them so convenient. Klaire Labs clearly takes quality seriously, and this product has definitely earned my trust. Highly recommend it to anyone looking to support their gut health naturally and effectively!
