    • Take 1 capsule daily with food, preferably breakfast, starting 3-5 days before departure, continuing during travel abroad and for a few days upon return from travel, or as professionally directed.
    • For anyone unable to swallow capsules, the content of the capsules may be mixed with a cold meal or beverage.

    Live cultures are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, infants with short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care. Keep out of reach of children.

It’s also gluten and sugar-free, and suitable for everyone over the age of 4 years (pregnant women should consult with a doctor before use). The capsules are very easy to swallow, or if desired, they can be opened, and the contents popped into cool, non-acidic drinks. These unique features combine to make it one of the easiest and best live cultures travel supplements to use for the whole family!

We recommend that our Optibac Travel Abroad are taken for at least 3-5 days before departing on your foreign travels.

As travelling can be more fun for you than it is for your stomach, it makes good sense to give your gut some love in the days before your trip. Drink plenty of water and avoid alcohol; eat foods containing plenty of natural fibre, such as beans, pulses, and whole grains, and begin to take your live cultures travel supplement. It is fine to use Travel Abroad in combination with your usual daily live cultures supplement. Take friendly bacteria regularly in between your foreign trips to keep your gut bacteria in balance.
