Like conventional medicines, dietary
supplements may cause side effects, trigger allergic reactions, or interact

make other health conditions worse.
Dietary supplements may not
be standardized in their manufacturing. This means that how well they work or
any side effects they cause may differ among brands or even within different
lots of the same brand. The form you buy in health food or grocery stores may
not be the same as the form used in research.
