I would personally take Floradix or Spatone since they're gentlest on the body, less adverse effects. I wouldn't worry though if your iron levels were between 85-105 since it is physiological and normal for your iron levels to be "low" in your third trimester.

A large study done on haemoglobin levels concluded that "the magnitude of the fall in haemogloblin concentration is related to birth weight", with highest average birth weight being in women whose haemoglobin concentration was between 85 g/L and 95 g/L.

Results showed that when haemoglobin concentration failed to fall below 105 g/L in pregnancy, there was an increased risk of pre-eclampsia, premature birth and low birth weight. Other studies indicate risks with haemoglobin and hematocrit values which are high, and that maternal anaemia usually is not associated with adverse risks and may be an indicator of increased maternal plasma volume.
