Title: 
Review of Recent Evidence on the Management of Heartburn in Pregnant
and Breastfeeding Women

Reviewer's report:
I suggest the inclusion of the amount of alginate (and other components) present
in the considered / cited papers. 
It is worthwhile to remember that "Gaviscon" is
presented with different concentrations in different countries. 
As such it is
important to refer what type / concentration of alginate that was used in different
studies.
