"In a recent study, a greater response in LDL cholesterol was observed
in men," says Anderson. "And in previous studies, older adults showed
greater reductions. Clearly, additional research is needed to clarify the
effects of psyllium in population subgroups."
Anderson tells WebMD that psyllium is a natural source of fiber that has
been used as a laxative for over 60 years. Though its mechanism of action is
unclear, data suggest that it lowers serum cholesterol by increasing bile acid,
