Probiotic Supplement Market

This study employed two primary approaches to estimate the current size of the probiotic supplements market. Exhaustive secondary research was carried out to collect information on the product form, health application, end user, distribution channel and ingredient segments of the market. The next step involved validating these findings, assumptions, and sizing with industry experts across the value chain through primary research. The top-down and bottom-up approaches were employed to estimate the complete market size. Thereafter, data triangulation was used to estimate the market size of segments and subsegments.
