Has anyone seen any followup research on the response to psyllium based on gender and pre/post menopause? Has any work been done around perimenopause? And what about psyllium impacts on the liver in post estrogen lives? Is the sample size too small?

(I am posting Science Direct but the original paper is in Pub Med)
