The card does not say who needs the supplement or whether it is needed by those who are not planning a pregnancy. It says that folic acid takes part in the processes of cell division and is an important part of the daily balanced diet; the daily dose is 400 mcg. The claims about blood formation and the regulation of protein metabolism have no confirmation.
General information (not a manufacturer's instruction): the supplement is not a substitute for a varied diet, and whether it is needed is decided by a doctor.
