What does Travelbiotic do?

Saccharomyces boulardii is a non-pathogenic yeast that has been used for the past 30 years for the prevention and treatment of digestive illness, especially diarrhoea, bacterial infection, parasitic infection and traveller’s diarrhoea.

Saccharomyces. boulardii was first discovered by French microbiologist, Henri Boulard in 1920. He noticed that Lychee fruit skins were a traditional treatment for diarrhoea. The anti-infectious properties of S. boulardii appear to be in part due to its ability to inhibit the growth of pathogenic bacteria in the gut, while improving the profile of beneficial microflora and subsequently, the health of the gastrointestinal system. This remarkable yeast is one of the great success stories in probiotic therapy.

Experimental studies support S. boulardii’s ability to bind to pathogenic bacteria, inhibit the growth of pathogenic bacteria and reduce inflammatory mediators. In the case of Shigella flexneri, a highly infectious bacteria, S. boulardii demonstrated the maintenance of gastrointestinal epithelial integrity whilst reducing the inflammatory response. Furthermore, S. boulardii demonstrated prevention of rotavirus-induced oxidative stress and the inhibition of the diarrhoeal signalling cascade. Likewise, S. boulardii prevented weight loss, inhibited bacterial translocation, bound pathogenic bacteria, reduced inflammatory signallers and stimulated immune function in a Salmonella model.

A review that discussed the evidence for S. boulardii and the healthy regeneration of the microbiota after diarrhoeal dysbiotic infections reported mechanisms that include the neutralisation of bacterial toxins and the dephosphorylation of lipopolysaccharides that led to a rapid and improved recolonised microbiota profile.

TRAVELLER’S DIARRHOEA - is estimated to affect more than 60% of travellers to developing countries, accounting for 40,000 travellers daily, or >15 million travellers annually. In terms of frequency and economic impact it is the number one health problem for international travel. Symptoms include vomiting, abdominal cramps, fever and diarrhoea, while a spontaneous cure usually occurs after four days, some patients may have symptoms that last weeks and some may develop irritable bowel syndrome.

The efficacy of S. boulardii for preventing traveller’s diarrhoea has been demonstrated in a large cohort of travellers (1016 subjects) who visited Northern Africa, the Middle East and the Far East.

Treatment with
S. boulardii commenced five days prior to travel and during the entire trip which lasted on average three weeks. Patients were assigned to placebo, S. boulardii at 250mg per day, or S. boulardii at 1000mg per day. S. boulardii was shown to significantly reduce the incidence of diarrhoea in a dose dependent manner, see figure 1.11 A second randomised, controlled trial with S. boulardii enrolled 1231 Austrian tourists travelling to hot climates and randomized them to either one of two doses of S. boulardii (250 or 500mg/d) or placebo for 3 weeks. The treatment started 5 days prior to the trip and continued through the duration of the trip. 43% of the placebo group developed traveller’s diarrhoea, but significantly fewer in either 250mg/d of S. boulardii (34%) or 500mg/d (32%). A further meta-analysis analysed 12 studies and subsequently concluded that S. boulardii showed significant efficacy in the prevention of traveller’s diarrhoea.


  • GIARDIA INFECTION - Giardiasis is the infection by the protozoa Giardia lamblia that is characterised by long lasting diarrhoea, weight loss, abdominal pain and weakness. A study investigated the adjunctive treatment of 750mg metronidazole thrice daily along with 250mg (5 billion) S. boulardii compared to metronidazole only for 10 days in a group of individuals that tested giardiasis positive. It was reported that 100% of the adjunctive group tested negative for the infection two weeks later compared to 82.9% of the metronidazole group. At week 4 of follow up, consistent outcomes were reported, thus leading the authors to conclude that adjunctive use of S. boulardii alongside metronidazole was efficacious in treating giardiasis.13


  • IMMUNITY - The ability of probiotics to treat and protect against recurrent gastrointestinal infection may be due to the enhancement of local immune defences and its ability to bind pathogenic bacteria. In children with acute gastroenteritis the administration of S. boulardii (250mg twice daily for seven days) resulted in a significant increase in CD8 lymphocytes and serum immunoglobulin A, furthermore a significant decrease was reported in C-reactive protein levels and stool frequency. The authors concluded that S. boulardii treatment enhances the immune response.

  • DIGESTIVE HEALTH the rhizome of Ginger (Zingiber officinale) has a long history of traditional use for digestive health. It is suggested that ginger confers direct effects on the gastrointestinal tract via its anti-bacterial, spasmolytic, carminative properties. A meta-analysis explored ginger’s anti- analgesic properties to conclude that ginger significantly exerted anti-analgesic effects, consequently such effects that may address to diarrhoeal-induced pain. A systematic review that incorporated 6 research papers to investigate gingers anti-nausea effect concluded that ginger overall was effective for reducing nausea.

S. boulardii may be effective for treating acute diarrhoea from a variety of

causes. A review discussed two studies, the first enrolled 92 outpatients with acute diarrhoea

administering S. boulardii or placebo daily for 8 days. By day 3, the S. boulardii subjects had significantly

lower diarrhoea severity score that the placebo group. The second study enrolled 57 patients with

acute Entamoeba histolytic dysentery and treated them with S. boulardii for 10 days or nothing

(control). Both groups also received metronidazole and iodoquinol for 10 days. By four weeks, 100%

of the S. boulardii group showed no symptoms compared to 19% of the controls.12
