PRINCETON — What is a dietary supplement? Should you take a supplement? Will a supplement interact with your prescription medication? Answers to these questions and more will be presented at the local leader lesson “Supplements or Food” sponsored by University of Illinois Extension – Bureau, LaSalle, Marshall, Putnam Unit.

Laura Barr, University of Illinois nutrition and wellness educator, will present the program via teleconference at 10 a.m. Feb. 21 at the University of Illinois Extension - Bureau County office, 850 Thompson St. in Princeton.
