It depends on the brand and the packaging, but generally 3-5 years is the accepted "Shelf Life" if kept in a cool dry environment. Older tablets with poor packaging may have a much shorter shelf-life, but generally it is printed on the bottle or package. Remember, The tablets may be good for much longer than that but the company does not want to take liability past that date.
