Why do I feel sick after probiotics?

It is possible to experience some side effects after taking probiotics. This is known as probiotic-associated side effects (PASE) and can include nausea, cramping, diarrhea, and headaches. Factors that may contribute to PASE include the type of bacteria in the probiotic supplement, the amount of bacteria in the supplement, and how long it has been since the probiotic was taken. It is also possible that your body is still adjusting to the new bacteria in your gut and that the symptoms should subside over time. If you are experiencing severe or prolonged symptoms, it is important to consult with your doctor.
