Or it will affect my pregnancy, also as the princical has zince and magnesium with it , the other substitiute have been offered was gemcal mom and osteocalcium syrup, but they do not have zince or magnesium in it, also they have added b12 but am alrwady taking livohen which has folic acid and iron, so which would be best princical or gemcal mom or osteocalcium during this period of pregnancy, kindly suggest
