The Future of Probiotics

Saccharomyces boulardii is an exciting probiotic yeast that's not harmed by the drugs and chemicals that can damage bacteria-based probiotics. This makes Saccharomyces boulardii the perfect choice for dogs with guts stressed by gut-harming drugs and chemicals. 

  • Helps maintain a healthy gut lining: Studies show S. boulardii can influence parts of the immune system that maintain proper gut permeability.
  • Low glycemic load: While most probiotics are carried in maltodextrin, which is high glycemic and can spike insulin, S. boulardii is free of dextrins and other harmful fillers.
  • Third party tested: For quality and purity.

Frequently Asked Questions

How is Saccharomyces boulardii different from other probiotics? 

Saccharomyces boulardii is a probiotic yeast while most probiotics are bacteria. As a probiotic yeast, S. boulardii is less susceptible to chemicals that can harm regular probiotics. 

Does Saccharomyces boulardii contain maltodextrin?

None of our products or ingredients contain maltodextrin. Maltodextrin is a partially hydrolyzed sugar that is ultra-processed, provides no nutritional value and carries the highest glycemic index of any other food. We make sure all of our ingredients are free of all dextrins so we can always support a healthy immune system and gut environment.

Should I store Saccharomyces boulardii in the fridge? 

We recommend keeping all Four Leaf Rover products in the fridge to maintain freshness. But if space is limited, you can store Saccharomyces boulardii in a cool, dark place.

Who We Are

In Memory of Simon & Aaron

The story of Four Leaf Rover started as a tragedy. Our founder Dana Scott lost two dogs from toxic sprays they were exposed to in the fields surrounding her home. In a frantic effort to save her dogs and protect her remaining dog family, Dana connected with most of the leading holistic veterinarians around the world about the most effective natural remedies. As Dana researched remedies, she found nearly all contained hidden or harmful ingredients. Four Leaf Rover began as a promise to Dana's lost dogs that all dogs deserve super premium products with natural ingredients that are thoroughly tested to be low in harmful pesticides and heavy metals. With a mission of quality, transparency and sustainability, Four Leaf Rover is making the world a better place for dogs and the people who love them.
