No. But I would not take Vitamin C (ascorbic acid, or sodium ascorbate)
with CS. It would likely product silver ascorbate.  I would take it at a
different time.  I also would avoid drinking citric juices at the same
time as taking CS, although I am not aware of any research that
indicates this could be a problem
