Folio^®iodine-free contains 400 µg of folic acid and 10 µg of vitamin B12 in one tablet and is particularly recommended for those who should not have any additional intake of iodine. Those with a particular requirement for folic acid and its cofactor vitamin B12 primarily include women planning a pregnancy, those who are pregnant and those who are breastfeeding. Furthermore, users of hormonal contraceptives as well as people who actively engage in sport have an increased folic acid requirement. Older people are advised to take folic acid combined with vitamin B12 and vitamin B6 (as contained in FolPlus^®).
