At one time, General Nutrition Center (GNC) was a major health products/supplements retailer, particularly here in the eastern end of the county. Based in Pittsburgh -- you couldn't swing a cat without hitting a GNC store in western PA They were everywhere. And GNC expanded nationwide and into foreign markets. But then competition arose -- here in PA, it was Whole Foods initially; now every supermarket and pharmacy sells similar products for a lot less. GNC just couldn't compete. Been in trouble for a long time, so bankruptcy was inevitable.
