Probiotics are natural food supplements and not a medicine or drug; side effects from taking probiotics are extremely rare. A large number of clinical studies highlight that our probiotic supplements are completely safe for human consumption, and research shows that it is very difficult to overdose on probiotics. It is worth noting that taking a very large amount of the probiotic Saccharomyces boulardii may cause temporary constipation in some people. We advise taking up to 6 capsules of Saccharomyces boulardii (formerly known as 'For bowel calm') in a day.

Side effects from prebiotics

Some people find that prebiotics (the food source for probiotics) can cause minor discomfort, bloating or wind during the first few days of taking them. However flatulence is simply a sign that the body's good bacteria is being stimulated and these symptoms should disappear and improve with time. As such, the benefits of taking prebiotics generally outweigh the minor discomfort you may experience initially. In the rare case that symptoms do not decrease after a few days, consider reducing your dose of prebiotics before gradually building it up again.

Note: Probiotics are not recommended for those with serious medical conditions eg. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, infants with short bowel syndrome, or to patients with open wounds following major surgery; unless under a doctor's care. Furthermore, pregnant or breastfeeding women should consult their doctor before taking Saccharomyces boulardii, 'For travelling abroad', or natural plant extracts as in 'For daily immunity'.
