Why Do Iron Supplements Cause Constipation?

Iron supplements cause constipation because the absorption of iron is weak from food as well as from supplements. On average 10% of iron from food is absorbed by the body for women and 5% for men. In case of iron deficiency, absorption increases up to 20%. Iron not absorbed by the body feeds bad pathogenic bacteria in the gut. Constipation is therefore a sign of predominant bad bacteria in the colon .

Although iron bisglycinate is known for being stomach friendly among divalent iron salts and causes side effects more seldom , some people are still more gentle to iron than others. Therefore, iron bisglycinate can cause constipation for some people. The bigger the amount of iron consumed, the higher the risk for side effects . For instance, side effects with Iron 30 mg and Iron syrup for children 25 mg are more rare, because the daily amount of iron is only 2530 mg. Superironis 60 mg iron, i.e. twice as much. However, Superiron is needed in case of diagnosed iron deficiency anemia and usually the choice for pregnant women. A lot of people do not have any side effects with iron bisglycinate independent on the amount consumed.

Why Women Should Pump Iron Supplements During Pregnancy

Youve just found out youre pregnant. Now youre focused on doing everything right, like eating a healthy diet, getting exercise, and choosing the proper prenatal vitamins including iron supplements.

Taking iron helps your body produce more blood. Thats a big deal for moms-to-be, because your total blood volume will double over the course of your pregnancy!

The average pregnant woman needs about 30 mg of elemental iron per day to meet the new demands of extra blood volume, the developing placenta, and growing fetus. Most combination prenatal vitamins contain this much iron, which is nearly double the amount a nonpregnant woman requires. However, you might need more than 30mg a day if you:

  • Have low iron at the start of your pregnancy
  • Are carrying twins or triplets
  • Took iron sporadically in early pregnancy
  • Started taking iron late in pregnancy

Approximately half of your iron intake will go toward the developing fetus and placenta. The other half will be used to increase the amount of blood in your circulatory system, which will help protect you during childbirth. In a typical vaginal delivery, youll lose approximately a pint of blood for a cesarean section, its closer to two pints . Having low blood volume can lead to complications during delivery and the postpartum period.

“Taking iron helps your body produce more blood. Thats a big deal for moms-to-be, because your total blood volume will double over the course of your pregnancy!”

For the 20 trials that included placebo as the comparator a significant increase in the incidence of gastrointestinal side-effects was observed with ferrous sulfate OR = 2.32 . Nineteen of these 20 placebo-controlled trials were conducted in healthy non-anaemic individuals and therefore hemoglobin repletion was not a primary outcome. The only placebo-controlled trial in anaemic participants was carried out in patients who became anaemic following joint replacement surgery and reported an average increase in hemoglobin of 1.94 g/dl following 6 weeks of ferrous sulfate therapy compared to an increase of 1.63 g/dl with placebo .
