Probiotic, Non-Colonizing Yeast Supplement
Saccharomyces boulardii is a non-pathogenic yeast that is recognized to have probiotic effectiveness used alone and/or in combination with other probiotics to support digestion. It usefulness was discovered by a group of French physicians investigating intestinal issues.


Saccharomyces boulardii is considered a non-pathogenic, non-colonizing baker's yeast species, which is very closely related to brewer's yeast also known as S. cervesiae. The S. boulardii, although it is recognized as a yeast, is not related to the Candida species (Candida albicans, tropicalas, etc.), which can cause pathogenic infections in the gastrointestinal and genitourinary tracts.
S. boulardii is a unique probiotic in that it is known to survive gastric acidity, it is not adversely affected or inhibited by antibiotics and does not alter or adversely affect the normal flora in the bowel. For this reason good friendly probiotic organisms (including Lactobacillus and Bifidobacterium) can be taken at the same time as S. boulardii.
For optimal results it is recommended that the capsule be taken between meals, on an empty stomach, with un-chilled water. Each size #3 Vegetable capsule contains 3 billion CFU (colony forming units).
S. boulardii should only be taken under the guidance and direction of a health care practitioner. This supplement is generally well tolerated; however, if any of the following symptoms occur, then stop and contact your physician: hives, rash, or itchy swollen skin, breathing problems or tightness in throat or chest. These symptoms may indicate an allergic reaction which may require medical attention or require that the product be discontinued. Other possible side effects may include gastrointestinal symptoms such as flatulence (gas) and constipation.
Do not take the S. boulardii supplementation at the same time as any prescription antifungals like Nystatin, Diflucan, Sporonox, etc. Antifungals are recognized to kill S. boulardii and thus should be taken at a different time of the day (separated by 2 to 3 hours) as is recommended by the physician.


Keep the bottle in a cool dry area. The product may be refrigerated and Kirkman actually recommends this for maximum stability. Store away from heat or direct sunlight as heat can adversely affect the potency of the supplement.
There is a growing body of documentation in the scientific and medical literature pertaining to the role of S. boulardii in supporting intestinal health issues.

As a dietary supplement: take one (1) capsule daily and/or as directed by a medical practitioner. For intensive use take one (1) capsule three (3) times daily, only as specifically recommended. Once gastrointestinal functioning is corrected and symptom response is improved then the supplement may be discontinues and use of other probiotic formulations may be indicated.
