To create a diverse microbiome, we need to feed our good bacteria with a highly diverse array of prebiotics. Research indicates we need 30+ sources of fiber weekly to achieve this. Fiber 35 is formulated with 35 Organic fiber sources. Nothing else comes close to offering this level of diversity. Fiber 35 is part of the exclusive Brenda Watson H.O.P.E. Formula for Optimum and Vibrant Health. The H.O.P.E Formula recommends a 35 grams of fiber per day from 35 sources per week.
