About this product
From The Feed's product listing:
Race travel, training camps, antibiotic courses, high-carb fueling — endurance athletes hit their gut with a lot. And when the gut goes sideways at the wrong moment, everything else does too. Saccharomyces boulardii is the most clinically documented probiotic for protecting gut function during exactly these high-risk windows, and Thorne Sacro-B delivers it at 5 billion CFUs per delayed-release capsule. What makes S. boulardii different from every other probiotic on the shelf: it's a yeast, not a bacterium. That one distinction changes everything about how and when it works. Antibiotic-Proof Gut Protection – Because S. boulardii is a yeast, antibiotics can't kill it. Most bacterial probiotics get wiped out alongside the pathogens antibiotics are targeting. Sacro-B survives the antibiotic course intact, actively protecting the gut lining and supporting the regrowth of beneficial flora w
