Why Saccharomyces Boulardii Works

Saccharomyces Boulardii (Sacro B) is currently the only yeast shown to have extensive research enough to support its use as a probiotic supplement. Unlike its close cousin Saccharomyces Cerevisiae known as Baker’s yeast, Saccharomyces Boulardii appears to be very heat and pH stable as well as support unique health outcomes in the human host. There are three primary areas that Sacro B has been shown to support.

  • Normal balance in the intestinal microbe colonies especially after eradication of microbial balance with medications.
  • Healthy intestinal barrier function
  • Normal stimulation of a healthy immune cell response in the intestinal tract.

Like a forest, the microbiota in the intestinal tract need to have a healthy balance of different organisms. If competitive or dominating organisms take hold, they may crowd out the beneficial organisms. On the opposite end of the spectrum, beneficial organisms like Sacro B have been shown to crowd out potentially problematic organisms. In fact, Sacro B has been shown to support a healthy response to potentially harmful organisms and a healthy bacterial balance in the GI tract. At the same time, due to what it eats and secretes, the presence of Sacro B appears to encourage the growth of beneficial bifidobacteria.

These organisms have been shown to support normal immune cell function and butyrate production that nourishes intestinal cells. Just like we make proteins, many probiotic organisms make proteins that they secrete into their environment. Sacro B has a tendency to produce proteins that may support healthy digestion of foods, bind to toxins that are produced by pathogenic microbes, and also support a healthy normal production of mucus from the local intestinal cells. Due to these factors and more, Sacro B supports a healthy immune system at the intestinal barrier as well as healthy barrier function.

Saccharomyces boulardii has been studied in clinical trials and has been found to help support gut health and may support health when presented with occasional diarrhea. Saccharomyces boulardii is a microorganism that plays a role in supporting normal intestinal absorption of D-glucose and sodium. This helps to maintain the normal uptake of water and electrolytes during occasional diarrhea. Saccharomyces Boulardii may also support healthy stool concentrations of short-chain fatty acids that help nourish colon mucosal cells.

Product Information & FAQ's

Who Needs Saccharomyces Boulardii

Finding the right probiotic supplement can be a challenge. Saccharomyces Boulardii may be right for you if you’re seeking support for:

  • A healthy intestinal lining
  • Normal digestion
  • Regular bowel movements
  • Normal intestinal microbiota balance
  • A probiotic supplement that doesn’t require refrigeration (great for travel!)
  • Gastrointestinal microbiome health during travel
  • Microbiome health during times of extra stress

Saccharomyces boulardii is an acid-resistant, temperature-tolerant probiotic yeast. Its high resistance to temperature changes makes it an ideal probiotic for traveling. In addition, its resistance to pH changes allows its contents to be easily mixed with food or beverages. This makes Saccharomyces Boulardii a great probiotic option for those who have trouble swallowing supplements.

Seeking Health’s Saccharomyces Boulardii contains 5 billion CFUs (Colony Forming Units) in each one capsule serving.

Saccharomyces is designed to help support and maintain balance in the intestines. This organism has been shown to compete with nutrition and binding sites with more harmful organisms. It also has been shown to produce proteins that may assist in the processing of toxins produced by potentially pathogenic microbes. The presence of Sacro B in the intestinal tract has been shown to encourage the growth of beneficial organisms as well. The 5 billion CFUs in this probiotic help maintain normal colonic populations of healthful organisms including bifidobacteria. If you are desiring a probiotic that helps support a normal and healthy intestinal tract, Saccharomyces Boulardii is a logical choice.

There are many different strains of probiotics and it can often be difficult to discern which one is right for you. Many of these probiotic options require refrigeration to maintain the CFU populations. Saccharomyces boulardii has been researched and tested to ensure that it is shelf-stable. This type of probiotic may work well for a busy lifestyle or a person who travels a lot.

This on-the-go lifestyle may also require more gut support as it often includes on-the-go meals or off-schedule meals. It is important to provide healthy support with probiotic strains targeted to support your gut health. Saccharomyces Boulardii supports a healthy gut barrier, intestinal microbiota, and immune system health.

If you’re looking for a new probiotic to support balance in your gut with various healthy microorganisms, Saccharomyces Boulardii may be exactly what your body and your busy lifestyle are seeking.

Choosing the right probiotic and supporting a healthy balance of your microbes is important. Check with your healthcare practitioner if you are unsure. Seeking Health offers multiple options:

  • Saccharomyces Boulardii provides support for a healthy intestinal tract and digestive function that is shelf-stable and can be used by travelers.
  • If you are looking to support histamine metabolism, ProBiota HistaminX is your go to.

Finding multiple probiotic strains which support your health adds to your microbial balance. Supporting this balance starts in the gut and may, for you, start with Saccharomyces Boulardii.
