Prebiotics serve as fuel for probiotics - they help the good bacteria thrive in your gut so your probiotics can get to work! Our Prebiotic, Organic Jerusalem Artichoke, is a sunflower root that's high in fiber and a natural prebiotic - stimulating and feeding the Bifidobacteria in the gut.

It also doesn't need to be refrigerated because i's freeze-dried!
