Your iron requirements can increase during pregnancy because your body produces more blood for you and needs to supply the baby. However, this doesn't mean that all pregnant individuals should automatically start iron supplementation at the same time. The safest and most practical approach is to follow the plan you receive from your doctor or midwife, and to monitor your blood tests (typically hemoglobin and often ferritin/iron stores).
The goal of this guide is to help you choose the right time and the right way to take iron in your daily life without unnecessary discomfort.
Iron supplement during pregnancy – when to start?
Many are advised to take iron supplements later in pregnancy, but the timing can vary. It depends, among other things, on your iron stores, whether you have previously had iron deficiency, and how you feel.
Practical rule of thumb
- Do not start "just to be safe" without an agreement with your midwife or doctor, especially if you have previously experienced stomach issues from iron.
- If you receive a specific recommendation, follow it, and rather have the dose adjusted than stop completely if you experience side effects.
Best time to take iron tablets during pregnancy
The "best" time is often when you achieve both the best absorption and can maintain it long-term. Iron is typically better absorbed when not taken with certain foods and drinks.
How to fit iron into your day
- Take iron separately from milk, calcium supplements, and calcium-containing products, as they can inhibit absorption.
- Coffee and tea can also affect absorption, so take iron at a time when you are not drinking them close together.
- Some tolerate iron best at night or with a small snack. If your stomach reacts, talk to your midwife about a solution rather than pushing yourself.
Iron deficiency during pregnancy: symptoms and when to get checked
Fatigue during pregnancy is common and can have many causes, so symptoms alone cannot determine the issue. However, if you experience pronounced fatigue, dizziness, heart palpitations, shortness of breath with light activity, or unusual paleness, it may be relevant to have your iron status assessed.
What can healthcare professionals measure?
- Hemoglobin (Hb), which indicates your blood count.
- Ferritin, which indicates your iron stores (not always, but often if deficiency is suspected).
Iron during pregnancy and side effects like constipation
It's completely normal if iron causes constipation, nausea, or an upset stomach. You haven't done anything wrong, and there are often adjustments that can help.
Gentle approaches you can try
- Drink plenty of fluids and prioritize fiber in your diet, if you can.
- Physical activity in daily life can help get the bowels moving.
- Talk to your doctor or midwife about changing the dose, timing, or type of supplement if the discomfort is significant.
Iron after childbirth and in the post-pregnancy period
After childbirth, some may need extra focus on iron, especially if there has been significant blood loss or if they started pregnancy with low stores. In this case, it makes good sense to have a plan for monitoring and duration, so you don't experience symptoms for an unnecessarily long time.
If you want to prepare practically for the period around childbirth and the time afterward, you can check out the Postpartum collection.
Relevant product (practical support during the postpartum period)
For some, it's convenient to have a ready-made package of postpartum essentials, allowing for rest and any supplement routines. See the New Mum Care Pack.
