What is Travelan® ?
Travelan® is an oral polyclonal antibody therapy developed to target the endotoxin lipopolysaccharide (LPS) and other pathogenic bacterial components in the human gastrointestinal tract. It is an over-the-counter product that helps to reduce the risk of Travellers’ Diarrhoea when you are travelling overseas. In Australia Travelan® is listed in the ARTG, AUST L 106709. It is specifically indicated to;
- Reduce the risk of Travellers’ Diarrhoea
- Reduce the symptoms of minor gastrointestinal disorders
Notably, Travelan® is not an antibiotic and will not cause antibiotic resistance.


When you take one or two caplets of Travelan® before a meal, the anti-ETEC antibodies lay in wait in the gastrointestinal tract. If you consume food or drinks that are contaminated with Travellers’ Diarrhoea causing bacteria, Travelan® utilises specific antibodies to bind the bacteria and the toxins they produce effectively neutralising them and inhibiting their attachment to the gastrointestinal tract reducing LPS-related inflammation and colonisation.
In short, Travelan® works to target and neutralise bacteria and the toxins they produce before they can make you sick and ruin your dream holiday! To learn about how Travelan® can support your digestive health when you’re at home on Staycation, click here.

Scientific Evidence
Travelan® has been shown in clinical trials to significantly decrease the risk of Travellers’ Diarrhoea and to decrease the symptoms of minor gastrointestinal disorders associated with Travellers’ Diarrhoea. Travelan® is an antimicrobial which underwent Controlled Human Infection Model (CHIM) studies. These studies were double-blind, placebo-controlled medical trials conducted in Europe and the USA. The trials showed protection of up to 90% against infection with E.coli (ETEC) and the development of TD. The trials have also shown that people who received Travelan® and subsequently were infected by E.coli had significantly less discomfort and diarrhoea, compared to those who did not receive Travelan®.
In addition recent studies performed by the US Defense Force show that the anti-ETEC antibodies in Travelan® are cross-reactive and react against other diarrhoea-causing pathogenic bacteria such as Campylobacter, other strains of Enterotoxigenic E.coli and Shigella – all potential causes of Travellers’ Diarrhoea.
Travelan® Ingredients
*Each caplet of Travelan® contains 200mg of “Hyperimmunised” Dairy (Bovine) Colostrum Powder which has been scientifically formulated to be rich in antibodies against the major bacterial cause of Travellers’ Diarrhoea. The non-medicinal ingredients of Travelan® used in the caplet manufacture include microcrystalline cellulose, croscarmellose, sodium, glucose, colloidal silicon dioxide and magnesium stearate. Travelan® has been tested and shown to be gluten free.

Travelan® Technology
The (Bovine) Colostrum Powder (BCP) in Travelan® is sourced from New Zealand dairy cows that have been specifically “hyper-immunised” with patented Immuron vaccines by experienced and qualified veterinarians. These vaccines illicit a strong immune response which allows the cows to produce very high levels of specific antibodies, against the ETEC bacteria and the toxins they produce that cause Travellers’ Diarrhoea. The antibodies bind to the ETEC bacteria and the toxins they produce, effectively neutralising them and inhibiting their attachment to the gastrointestinal tract reducing LPS-related inflammation and colonisation.
Bovine Colostrum Powder also contains other natural occurring factors that have non-specific antimicrobial properties such as lactoferrin and lactoperoxidase which may aid in the relief of symptoms of minor gastrointestinal disorders.
Animal Health and Welfare Standards
Immuron has partnered with Synlait, an innovative and trusted dairy company based in New Zealand, for the supply of its bovine colostrum powder. Synlait specializes in the processing of infant formula and special milk powders and operates under an internationally accredited ISO/IEC 17065 dairy assurance system. Synlait only partners with certified dairy farmers which exceed New Zealand’s Animal Health and Welfare standards. In addition to this, Immuron’s commercial operations are managed by experienced and qualified veterinarians. A small portion of colostrum is harvested from selected dairy farms for processing, leaving plenty for the calves and standard dairy farm requirements. The health and welfare of a herd impacts directly on milk quality. The best dairy farmers know this and work hard to ensure a happy, healthy herd. It’s the proactive steps they take today that help improve milk production tomorrow. Click here for more information on Synlait’s Lead with Pride programme.
