The offer from Natra Pure was for a trial sample.  When the sample arrived a note on the back of the packing slip said you will be billed $92. per month.  Trying to call that number ends up with a long delay before the line goes busy.  When I finally got through it gave another number which I am about to research, 10-15-15-8000.  The ingredients are not more than a laxative no more than psillium.
