Probiotics are living bacteria, and like all living things, they require food to survive and thrive. Yacon Root acts as a steady and reliable fuel source for probiotics, like ProbioSlim, helping to ensure that you enjoy its maximum benefits. Prebiotics are indigestible fibers that act as a food source for the beneficial bacteria in your digestive tract. Probiotics, such as those contained in ProbioSlim, will be more effective when paired with the natural prebiotics in ProbioSlim's Yacon Root. By adding Yacon Root to your daily routine, you are ensuring that your probiotic will have the greatest chance of helping you reach your goals.
