I used http://www.webmd.com/interaction-checker/default.htm to check for possible interactions between my vitamins and minerals. www.webmd.com also seems to have a rather nice database with info on various supplements and drugs. Your combo seems clear. One thing you might want to be careful about is that all fish oil, curcumin, and your lexapro drug seem to have blood thinning effects (and therefore increase your risk of bleeding).
