Iron in pregnancy

EFSA sets the same 16 milligrams a day for pregnancy as for other premenopausal women. That is one of the most counter-intuitive numbers on this site, and it needs the explanation that goes with it.

EFSA märkus sellel real:EFSA ei sea tõusu üle premenopausaalsete naiste

Need on avaldatud rahvastiku võrdlusväärtused, mitte diagnoos ega retsept. Võrdlustarbimine kirjeldab, mis katab terve rühma; see ei saa öelda teie enda staatust ja ükski leht ei saa. Rasedus, krooniline haigus, ravimid ja malabsorptsioon muudavad pilti — viige need küsimused arsti, ämmaemanda, apteekri või dietoloogi juurde.

Why the published number does not rise

A pregnancy costs iron: the fetus and placenta take it, and maternal red cell mass expands substantially. Against that sit two things. Menstruation stops for the duration, removing the largest routine loss. And iron absorption increases markedly as pregnancy progresses, to a multiple of the non-pregnant rate by the third trimester.

EFSA judged that those adaptations, together with iron mobilised from stores, offset the additional demand across the pregnancy as a whole, and set the same 16 mg a day. It is a statement about a population average with adequate stores at conception, and EFSA said so.

Which is why iron deficiency in pregnancy is still common

The adaptation argument assumes reasonable iron stores at the start. Many women enter pregnancy with low stores precisely because the premenopausal requirement is hard to meet, and the demand is concentrated in the second half of the pregnancy while the stores were built before it.

That is why antenatal care in the Baltic and Nordic countries measures haemoglobin and, where indicated, ferritin, rather than relying on a dietary reference value. Anaemia in pregnancy is associated with poorer outcomes, and it is treatable. The measurement is the point.

What to do with this page

Use it to understand why a table says one thing and your midwife says another: they are answering different questions. A reference intake describes a population; your antenatal team is looking at your blood.

Do not start or stop an iron supplement in pregnancy on the basis of a web page. Iron supplements are commonly prescribed in pregnancy and commonly not, depending on the blood results, and taking them unnecessarily causes constipation and nausea at a time when both are already likely.
