What Are Probiotics?

Health Canada and the World Health Organization define probiotics as "live microorganisms which, when administered in adequate amounts, confer a health benefit to the host."8 The human body hosts approximately 100 trillion microorganisms, also known as microbiota or microflora. When the flora in your digestive system becomes imbalanced due to antibiotics, viruses, or unfriendly bacteria, it can lead to abdominal discomfort and diarrhea. Probiotics help balance your gut flora to support a healthy digestive system.

The History of Florastor®


While traveling in Indochina in the early 1920s, Henri Boulard, a French microbiologist, noticed the locals drinking a special tea—made from lychee and mangosteen—to help with digestion. Fascinated by the healing properties of these two tropical fruits, Boulard conducted further research and discovered the active ingredient to be what he later called Saccharomyces boulardii.

S. boulardii was first introduced to the market in 1953 by the French pharmaceutical company, Biocodex. Since then, it has become available in over 100 countries making it the #1 probiotic worldwide.

Florastor is the only probiotic in North America to contain S. boulardii lyo CNCM I- 745. With over 60 years of use and research, Florastor is the trusted probiotic of choice by families around the world.9
