Probiotic products come in many different doses and variable bacterial strains. People suffering from IBS who would like to try probiotics should check the label of their chosen product. Some products contain other ingredients that can make IBS symptoms worse such as FODMAPs: prebiotics including FOS and inulin, the dairy sugar lactose, fructose, and low calorie sweeteners including sorbitol and xylitol.
Many people want recommendations for specific probiotic products but these are difficult as there is inconsistency in the results that look at the benefit of probiotics. For instance, some probiotics only have one small study to support them whilst others have none.
There is currently not enough evidence to make specific recommendations for products although some do have better evidence profiles than other which your dietitian can discuss with you.
