Ready Fiber is a highly concentrated prebiotic liquid fiber supplement that allows you to easily get 12 grams of fiber (54% of the Recommended Daily Allowance of fiber) - all in one ounce of clear liquid. That's 300% more fiber than the leading brand. The days of gunky powders, handfuls of pills, and full glasses with barely any fiber are over. Plus, every serving includes prebiotics, which support healthy digestion and a strong immune system by nourishing the beneficial bacteria in your gut. These prebiotics also supercharge any probiotic supplement you may take.
