Secretory IgA (sIgA) is a mucosal Immunoglobulin and our first line of defense against invading microbes. It is found in mucus and secretions both from the intestine and lining of the lungs. It is interesting that recent research has shown that support of the friendly bacteria in the gastrointestinal tract, results in better immunity towards the common cold. In a comparative study of the Bifidobacterium, Escherichia coli, Lactobacillus and the Saccharomyces boulardii mainly the Saccharomyces boulardii induced higher levels of sIgA (Martini FS, et al. 2009). The researchers concluded that the Saccharomyces boulardii presented better characteristics in terms of immunomodulation. Saccharomyces boulardii is a so called probiotic yeast with a lot of research behind it. It is an excellent supplement to bring with you when you are traveling, since it has shown to significantly reduce the incidence of diarrhea (Kollaritsch H., et al. 1993, McFarland LV, 2007). This research was a placebo-controlled, double blind study were Saccharomyces boulardii were administered prophylactically to 3000 Austrian travelers and a significantly reduction of diarrhea was observed. Research has also documented the benefits of Saccharomyces in preventing diarrhea after the use of antibiotics. This probiotic supplement also has another benefit. It does not have to be refrigerated like other probiotic formulas, which makes it a lot easier to use. For adults, 500 mg twice daily seems to be the most effective dosage.
