Prebiotics Matter More

While probiotics add bacteria, prebiotics feed the bacteria already living in your gut. Prebiotics are specific fibers that your own enzymes cannot digest but beneficial bacteria thrive on.

Probiotics are like planting seeds in a garden; prebiotics are like fertilizing the soil. If the soil is poor, the seeds will not survive. That is why many researchers believe a high-fiber diet matters more than probiotic supplements for most people.
