Like many people, I came across Saccharomyces boulardii (S. boulardii) while I was forced to take a course of antibiotics. As I began to do my research, I realised that this crazy little probiotic yeast is one of the most proven supplements on the market today, with hundreds of peer reviewed studies proving efficacy.

(Warning, poo disclosures on the way).

Once I began with S. boulardii, I noticed an immediate, significant improvement in digestion and stool consistency, even while on antibiotics. Amber, another Gene Food contributor, gets squeamish when blog posts discuss poo, but who are we kidding?

I don’t take S. boulardii every day, instead like most probiotics I use; I cycle it, taking S. boulardii for a week or two when I feel my body needs it.

I am going to do a thorough breakdown of S. boulardii’s benefits in a moment, but one of the most interesting for me is S. boulardii’s ability to beat back Candida. Candida is a pathogenic yeast that’s found in everyone’s intestinal tract, but it can proliferate beyond healthy levels when our gut flora is disturbed, or when we drink a lot, or take a course of antibiotics.

S. boulardiihas been shown to be effective at killing Candida, and suppressing expression of the inflammatory markers it produces. Since Candida overgrowth is relatively common, S. boulardiiis a probiotic many people will be able to benefit from at some point in their lives.

  • Saccharomyces boulardii ( boulardii) is a strain of non-pathogenic yeast first discovered in French Indochina by Henry Boulard in 1920.
  • boulardiihas been shown in multiple clinical trials to benefit human health, including reducing the incidence of antibiotic associated and traveller’s diarrhoea.
  • Because  boulardiiis a yeast microbe, it cannot be killed by antibiotics and is an ideal supplement to pair with antibiotics.
  • boulardiihas been shown to be effective at combating Candida AlbicansH. PyloriClostridium Difficile, and other pathogenic yeast and bacteria strains.

The highest-quality S. boulardii preparations are lyophilized (freeze-dried) and generally contain 5 billion CFU (colony forming units).
