Are there any side effects from taking probiotics?

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.

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.  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.

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 For bowel calm S. boulardii in a day.

For further information, read up on clinical trials on our probiotics.

Note: Probiotics are not recommended for severely immunosuppressed patients, infants with short bowel syndrome (SBS), post cardiac surgery patients, patients with pancreatitis, patients in the Intensive Care Unit or patients with blood in the stool; unless under a doctor's care.
