There are many different shakes that can be good for IBS, as long as they are low in FODMAPs. Some people find that a dairy-free shake works well for them, while others may prefer a plant-based shake. There are also many different flavors and brands of shakes available, so it is important to find one that you enjoy drinking. If you have trouble finding a shake that works for you, talk to your doctor or dietitian about other options.
