I take VSL#3 which is absolutely considered a "pharmaceutical grade" probiotic because it is classified as a medical food. So no, that is incorrect. It also has plenty of clinical research on regulating immune-related cytokine expression, which is vital for people like me who suffer from IBD. Not all probiotics are created equally.
