"This was the best Probiotic to have my dog take with her antibiotics. She has a sensitive stomach and I didn’t want her vomiting or getting diarrhea while on the harsh antibiotics. Giving this, she has not had one issue."

Unlike most probiotics, Saccharomyces boulardii is a yeast-based probiotic. This means that it helps inhibit yeast populations and is not negatively affected by antibiotics, ideal for dogs on gut-harming medications or antibiotics.

Saccharomyces boulardii is a robust probiotic with many benefits including:

  • Helps to maintain proper intestinal permeability
  • Helps to maintain a healthy gut
  • Helps with digestive upset

Our Saccharomyces boulardii is made in small batches and is third-party tested for quality and purity. This allows us to make it without the high glycemic ingredients that are often found in other products. Instead, we use natural inulin from organic Jerusalem artichoke which allows it to maintain its potency.

Every jar of Saccharomyces boulardii comes with a 30-day money-back guarantee so you can be confident in your purchase.

How should I store Saccharomyces Boulardii?

We recommend you keep Saccharomyces Boulardii in the fridge. If not, make sure you keep it in a cool, dark place.

Can Saccharomyces Boulardii cause yeast infections?

No. S. boulardii is indeed a probiotic yeast but don't let that scare you, it doesn't mean that it causes yeast infections. Some studies actually show that it can be used to reduce unhealthy yeast.

Can I give Saccharomyces Boulardii if my dog is on antibiotics?

Not only can you give Saccharomyces boulardii if your dog is on antibiotics, but research shows that that is exactly when you should be giving your dog S. boulardii. Specifically, research shows that giving S. boulardii can help manage or even prevent antibiotic-associated diarrhea.

How quickly does Saccharomyces Boulardii work?

Studies show that S. boulardii can populate within half an hour when given orally and steady state concentrations are achieved within 3 days. S. boulardii also stays in the gut for 3-5 days, which is much longer than most probiotics.

How is Saccharomyces Boulardii different than Protect?

Saccharomyces boulardii is a probiotic yeast while Protect is a soil-based probiotic. Probiotic yeast is less susceptible to antibiotics and other damage caused by medication making it ideal for dogs that are on those medications.

Is Saccharomyces boulardii a natural part of my dog's gut flora?

Yes it is! Saccharomyces boulardii is a normal part of your dogs intestinal flora. This study shows that S. boulardii levels are higher in patients with unbalanced gut flora due to antibiotic use.
