Femme enceinte prenant un complément alimentaire à base de bisglycinate de fer – supplément doux pour prévenir l’anémie pendant la grossesse.

Iron-rich supplement to support your pregnancy

Choosing an iron-rich food supplement is first and foremost a question of form and tolerability. Iron is well known for its digestive side effects (nausea, stomach pain, constipation), which often lead people to stop the course too soon. That is why we chose iron bisglycinate, a form that is well absorbed by the body and significantly better tolerated than standard ferrous salts.

In this collection, you will find Iron Mama, our capsule formula based on patented Ferrochel™ iron bisglycinate, providing 14 mg of iron per capsule. It is a non-haem iron suitable for a vegan diet, available without a prescription. For variety, our iron-enriched snacks such as Croquantissime, Granochoc and Chococo complement your daily intake. On each product page, you can check the composition, dosage, format, price, reviews and delivery information.

Iron supports every stage of motherhood. When trying for a baby and during pregnancy, it supports oxygenation of both mother and baby. After birth, it helps rebuild reserves depleted by blood loss — a key factor for your energy levels and to help limit fatigue during the post-partum period.

Key takeaway: for a well-tolerated iron supplement, the form matters as much as the dosage. Iron bisglycinate has high bioavailability and causes far fewer digestive side effects than ferrous salts. As iron requirements are particularly high during pregnancy — where anaemia can affect up to 56.9% of women in the third trimester — a well-tolerated supplement helps you sustain the course over time.

The form of iron makes a significant difference to its absorption and digestive tolerance. Classic ferrous salts, such as sulphate, are often associated with nausea, abdominal pain or constipation. Iron bisglycinate is the best-tolerated form: its bioavailability reaches 90.9% and it causes significantly fewer digestive side effects. A study in 150 pregnant women compared 15 mg of bisglycinate with 40 mg of ferrous sulphate: 30.8% of women remained deficient with bisglycinate, compared with 54.5% with sulphate. This is the form, via patented Ferrochel™, that we have chosen for Iron Mama.

An iron supplement such as Iron Mama is available over the counter, without a prescription, unlike some heavily dosed iron medications. That said, caution is still warranted: iron should not be taken blindly, as excess iron is not without risk. If you suspect a deficiency, it is better to check your iron status with a blood test before starting a prolonged course.

Iron is an essential nutrient for the production of haemoglobin and myoglobin, and therefore for the transport of oxygen throughout the body. It also contributes to growth, gene regulation, and the normal functioning of the immune system. It plays a role in brain function, particularly in the synthesis of neurotransmitters such as dopamine and serotonin, which influence mood and cognitive abilities. Finally, iron contributes to the reduction of tiredness and fatigue, a claim recognised by the EFSA.

The amount of iron actually absorbed depends on diet: it is estimated at 14 to 18% for a mixed diet, and 5 to 12% for a vegetarian diet. There are two dietary forms: haem iron of animal origin, which is better absorbed, and non-haem iron of plant origin. People following vegetarian or vegan diets are therefore more at risk of iron deficiency. Good sources include liver (favouring poultry liver during pregnancy due to its vitamin A content), red meat, sesame seeds, and lentils. Vitamin C improves the absorption of iron, particularly from plant sources.

Iron deficiency is one of the most widespread nutritional deficiencies in the world, affecting primarily children and women, largely due to menstrual losses. During pregnancy, when requirements are very high, supplementation is often beneficial. However, iron should not be taken without guidance, as an excess can be problematic. Before supplementing, seek advice from your GP or midwife and, if needed, have a blood test to tailor your intake to your individual situation.

From the moment you start trying for a baby, good iron levels matter. A deficiency can affect egg quality and endometrial receptivity, and adequate intake is associated with a reduced risk of ovulatory disorders. Iron and vitamin B9 also work together: a lack of iron can disrupt the use of B9, which contributes to reducing the risk of neural tube defects in the very early stages of pregnancy. A choline supplement could also be beneficial.

This is one of the benefits of preparing your nutrient intake in advance, as our collection offers fertility.

Iron requirements increase considerably during pregnancy, to the point where demand can almost increase tenfold. A study conducted in France found that 32.8% of pregnant women had anaemia, a proportion that rises to 56.9% in the third trimester. Iron ensures oxygenation of the mother, the placenta, and the baby, and allows the foetus to build its own stores for its first months of life. Supporting iron intake is therefore one of the key areas to monitor during pregnancy.

Iron is crucial for ensuring an optimal oxygen supply to the mother, the placenta, and the foetus. It is necessary for the foetus's own oxygenation and for building its iron stores, which will be used during the first six months of life. Children born with low iron stores are at risk of deficiency as early as 9 months. To improve the iron status of the newborn, some studies suggest that delayed umbilical cord clamping can improve iron concentration and haemoglobin levels at 2 months.

A low haemoglobin concentration in the first trimester is associated with an increased risk of premature birth and low birth weight. Moderate to severe maternal anaemia can also result in a baby that is small for gestational age.

Low iron intake in the mother, particularly during the third trimester, can affect the brain development of the foetus.

Our iron supplement for pregnant women helps to meet your needs. It can be taken alongside our range of pregnancy food supplement.

If you are breastfeeding, the iron content of your breast milk remains relatively stable, as your body draws on its own reserves to meet your baby's needs. Ensuring adequate iron intake therefore helps to reduce the risk of deficiency in the mother, especially as reserves may already have been depleted by childbirth.

After giving birth, iron requirements remain high due to blood loss, which also depletes reserves. The WHO recommends iron supplementation in the postpartum period, alone or combined with vitamin B9, to improve the mother's iron levels and reduce the risk of anaemia. Low reserves can be accompanied by marked fatigue and low mood. Our collection postpartum can very easily be combined with an iron supplement.

Iron deficiency is a known cause of hair loss, as many hair follicle genes are sensitive to iron. After giving birth, you will have lost a significant amount of iron, which can worsen hair loss that is already common during this period. Supporting your iron intake forms part of a broader routine, alongside our collection hair.

Choosing and tolerating your iron supplement well

Which form of iron to choose: the case for bisglycinate

All our formulas are based on iron bisglycinate, a form in which iron is bound to an amino acid. This structure gives it good absorption and better digestive tolerance than conventional ferrous salts, which are often poorly tolerated. Digestive comfort is a real concern: many people stop their iron course because of stomach pain or constipation. With Iron Mama, 14 mg of iron is delivered in a single vegan capsule, for a simple intake — morning or evening — with no prescription required.

Iron and motherhood: why requirements increase

Pregnancy is the period when iron demand is at its highest throughout a woman's life. Iron is used to produce haemoglobin, which carries oxygen to the mother, the placenta, and the baby, and it enables the foetus to build up its own reserves for its first months of life. These requirements increase most during the second and third trimesters, when anaemia becomes most common. The postpartum period and heavy periods are other situations where a targeted intake makes particular sense, especially for women who already have low stores.

Iron-rich foods and good absorption

Before or alongside a supplement course, diet remains a key lever. The table below lists some interesting sources of iron, ideally to be paired with a source of vitamin C for better absorption.

Iron (per 100 g): Sesame seeds (15 mg), Lamb (12.4 mg), Poultry liver (12 mg), Cooked clams (10 mg), Flaxseeds (10 mg), Chia seeds (8 mg), Lentils (7 mg)

Did you know: vitamin C significantly improves iron absorption, especially iron from plant-based sources. A squeeze of lemon over your lentils or a kiwi for dessert helps your body make the most of it.
Mama tip: if a form of iron has previously upset your stomach, don't give up just yet. Bisglycinate is generally much better tolerated digestively, and can be taken in the morning or evening, whichever suits you best.
If you are currently on medication, have a medical history, or an existing condition, pay close attention to possible interactions and the precautions listed on each product page. A food supplement supports a healthy lifestyle and a varied diet — it does not replace them.
