I stopped at this GNC to check out some of their vitamins and supplements and I took a closer look at their Brain and Energy supplements...I have seen many of the TV ads on Neuriva and Prevagen and I was a bit intrigued by them.... Both were around $40 for 30 doses. The guy working here was very helpful and nice answering questions. GNC has their own Brain Health formula brand, which carries 60 capsules for $40...so..... half the unit price....a better deal...but I wonder about the efficacy of it ???!! So I better do more research to find out how these compare..... I've noticed that when I watch Jeopardy now, my brain does not come up with the answers as quickly as before and sometimes it takes me a few seconds to yell out the right answer....so....Maybe my brain functions are slowing down....LOL.... ???!?!!!! This chain of stores is really good at focusing their products toward health and wellness...and it all started back in the 1930s when David Shakarian opened a small corner market selling heath based products. Today, GNC's headquarters resides just two blocks from David's original Pittsburgh store. read more
