I Saw An Ad For "Instaflex" With Collegen Which Is

I saw an ad for "Instaflex" with collegen which is supposed to be 2X more effective for joint pain than glucosamine and chondroitin. Here's their sentence: "Instaflex Advanced includes a patented form of Boswellia serrata called AprèsFlex® that was shown in multiple studies to provide joint relief in just 1 week!" It is apparently also at GNC. I have joint pain in my thumb and little fingers. What can you tell me abou5t this product? thank you, Margy Niemack, Albuqueruqe NM
