How To Use

Take 1 capsule daily with food, preferably with breakfast, throughout your antibiotic course and for a few days afterwards, or until the pack has been completed – can be used on an ongoing basis for those on long term antibiotics.

Can be taken at the same time as antibiotics - strains in this product have been clinically trialed alongside antibiotics and found to reach the gut alive.

Drink plenty of water with your course of probiotics.

For anyone unable to swallow capsules, open and mix contents of the capsule with a cool meal or beverage.


Live probiotic 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.
