The function of iron is to transport oxygen in the blood through red blood cells.

One of the first signs characterized by an abnormally low number of red blood cells is indeed a clearly visible pallor inside the eyelids. Easy to verify. Especially if you feel excessive and permanent fatigue. The most common cause of anemia is iron deficiency

Its definition is biological: we speak of anemia when the hemoglobin level in the blood is less than 13 g / dl in men, 12 g / dl in women.

With or without anemia, the symptoms of iron deficiency are varied: 1. Fatigue and dizziness 2. Paleness 3. Decreased physical strength, shortness of breath on exertion 4. Impaired cognitive functions (growth retardation, developmental delay, poor concentration skills, learning difficulties) 5. Hair loss 6. Sensitivity to cold 7. Palpitations, tachycardia 8. Restless legs syndrome

A person who is deficient in iron may experience one or more of these symptoms.

Iron takes oxygen from our lungs, loads it into red blood cells, and carries it to all cells in our body, including the uterus. Our cells use this oxygen to make energy, including the energy needed for a baby to develop in utero.

Certain groups are particularly at risk of developing iron deficiency: • Pregnant and lactating women • Vegans and vegetarians • Women who have heavy periods • People whose diet is not sufficiently rich in nutrients • Children with behavioral disorders or Attention Deficit Hyperactivity Disorder (ADHD) • People suffering from fatigue, depression or mental confusion • People taking antacid medicines to treat heartburn • People with digestive disorders, such as celiac disease, colitis, Crohn's disease and bacterial overgrowth in the small intestine

Getting enough iron from our diet alone is not necessarily straightforward, especially when taking into account the increased iron requirements during pregnancy and breastfeeding. Nausea, constipation, and aversion to certain foods can be additional barriers to eating an iron-rich diet. Health Canada recommends daily supplementation of 16 to 20 mg of iron per day during pregnancy

Avoid consuming foods that inhibit iron absorption within two hours of taking an iron supplement or eating foods rich in iron These foods include black tea, coffee, cocoa , foods rich in calcium such as dairy products, almonds and broccoli.

Oral iron supplementation may be considered with a doctor. Taking the supplements is recommended on an empty stomach to promote absorption, but this may cause side effects (nausea, abdominal pain). During the meal the absorption of supplements decreases by two thirds. However, in the event of adverse effects, a reduction in the dose may be considered as well as taking it with a meal.

It is strongly recommended to consult a doctor before taking any medication.
