Kapp-X is designed to be an anti-inflammatory product, targeting a number of different mechanisms, but primarily NFkB (Nuclear Factor Kappa Beta).  NFkB is said to be the "gas pedal" for inflammation in that, when it is activated, tells the nucleus of a cell to express a number of pro-inflammatory molecules. 
Unlike something like aspirin, or even COX inhibitors, this product attempts to go deeper at stopping inflammation before it happens.
