The LittleMe 1st Trimester does not contain iron due to the recommendations of the Polish Society of Gynecologists and Obstetricians, which state that before the 16th gestational week (in the 1st trimester), iron supplementation is only recommended for women with diagnosed iron-deficiency anemia.  If your doctor informs you that you suffer from iron deficiency, you can use our LittleMe 2nd and 3rd Trimester supplement, which contains this ingredient.
