Are there any side effects from taking BioGaia probiotics (Protectis/Gastrus/Prodentis)?

Since every gastrointestinal tract is unique some individuals might experience a temporary change in gut motility. BioGaia probiotics very rarely cause side effects in the amounts recommended for the products. Some individuals might experience gas (flatulence), but that generally disappears after a few days. No serious adverse effects have been observed in clinical trials up to the maximum tested dosage of 10 billion CFU per day.
