hi
this is reaqlly strange,because my vet is rxing this for our bullmastif,who had cancereous systs removed,along with some other vitamens to help prevent them from coming back,I have switdhed him to the golden flax seeds,because it is easier than the big jell cap to put in his food.I have been taken the capsil for many years to help with my m.s.Who really knows.No cancer here,just m.s.and diabetes
