Deutsche Heilbrunnen, in its last newsletter, explains how sulfate-containig mineral water improves stool frequency significantly.

Their article is based on the study Effects of Sulfate-Rich Mineral Water on Functional Constipation: A Double-Blind, Randomized, Placebo-Controlled Study conducted by Johannes Naumann, Catharina Sadaghiani, Roman Huber and Felix Alt, a&r’s Head of Clinical Operations.

A 3-week treatment with 1 l/ day of the sulfate-rich mineral water improved the frequency of bowel movements in subjects with FC compared with tap water; however, the difference was no longer significant after 6 weeks. Further evaluation in rigorously designed clinical studies will be necessary to validate the impact of sulfate-rich natural mineral water on FC.
