What is iron?
.
Iron is a mineral essential for the proper functioning of the bodyand. It is a component of haemoglobin, the protein responsible for transporting oxygen in our bodies. Iron affects neurological development, physical growth, synthesis of selected hormones and cell function .
What are the types of iron?
.
The iron we provide to the body with our diet comes in two formsand: haemic and non-haemic. The first type can be found in animal products such as poultry, meat and seafood. Non-heme iron, on the other hand, can be found in plant foods (nuts, seeds and pulses).

Iron - properties
.
Iron is essential for our body to function properly. What does it affect?
Alleviation of fatigue
.
Iron is necessary for the production of haemoglobin (a protein, in red blood cells, that is responsible for transporting oxygenand). Iron deficiency results in a lack of sufficient oxygen to be delivered to all areas of our body. This can result in feeling tired .
This problem often affects women during their childbearing years. Research suggests that iron supplementation is helpful in combating fatigue in menstruating womenand.
Fatigue can also be affected by inadequate concentrations of other ingredients. You can find out about them in the following articles:
Prevention of anaemia
.
One of the most common causes of anaemia is iron deficiency . Anaemia leads to fatigue, weakness or shortness of breath, and if untreated results in heart failure . Studies indicate that daily iron supplementation reduces the incidence of anaemia in menstruating womenand.
Improving sports performance
.
Iron deficiency is common in athletes, especially young female athletes who train in endurance sportsand. Some experts believe, that these individuals have a 70% greater need for iron. Lack of this mineral impairs sports performance .
Sports performance can result in joint problems. Collagen is partly responsible for their health. You can find out more about it in the following articles:

.Cacao Bloom is premium collagen (5000 mg) with Dutch cocoa. A researched formulation, convenient dosage and unforgettable taste.
Aiding the treatment of restless legs syndrome
.
Prestless legs syndrome is a condition that manifests as an uncontrollable need to move the lower limbs - usually in the evening or at night, which disrupts sound sleep. Research suggests that taking iron may support the treatment of restless legs syndrome.
Cognitive enhancement
.
Iron deficiency leads to problems with concentration, and impairs cognitive functionand. Supplementing the lack of this mineral can have an immediate effect. Studies show that taking iron positively affects memory, as well as cognitive and motor skills .
Cognitive function is also affected by:
.
How else does iron work?

-
Influences the normal course of pregnancy (iron is responsible for supplying oxygen to the baby)and.
-
Positively influences the growth and development of childrenand.
The European Food Safety Authority reports that iron supports energy metabolism and also plays a key role in cell division.
The ninth B vitamin, also known as folic acid, is also important for normal pregnancy development.

Iron deficiency
.
Iron deficiency is dangerous and leads to anaemiaand. It is common worldwide and occurs in many people. More often than not, iron deficiency is the cause of anaemia. What leads to it?
Causesand iron deficiency:
-
unbalanced diet,
. -
pregnancy,
.
-
excessive blood loss due to menstruation,
- .
-
impaired iron absorption,
- excessive loss of blood due to menstruation,
- excessive loss of blood due to menstruation,
- excessive loss of blood.

intrinsic bleeding,
- Intrinsic iron absorption disorders,
-
Genetic condition,
- .
-

How to quickly replenish iron in the body?
.
In most cases it is easy to get rid of anaemia caused by iron deficiency. Taking the right diet or supplementation will most often solve the problem. Untreated anaemia, however, can be very dangerous.
.
Effects
.
-
Complicationsand pregnancy.The high need for iron during pregnancy has its reasons. Deficiency of this mineral can lead to premature birth, intrauterine growth retardation, asphyxia (an oxygen-deficient state in the body), low birth weight or neonatal anaemia.
-
Acceleratedand or irregular heartbeat. Low oxygen in the body needs to be compensated for by a faster heartbeat. In the long term, this can lead to heart enlargement or heart failure.
-
Delayedand growth in young children. Untreated iron deficiency can delay growth and development in children and infants. Furthermore, a lack of this mineral in the body, increases susceptibility to infections.
Iron excess
.
Excess iron is just as dangerous as iron deficiency. What causes it?
Causes of excess iron:
.
-
Overdose. This occurs if we take too much iron along with supplements or medications.
-
Hemochromatosis. It is a disease that causes excessive iron absorptionand.
-
African iron overload. It is caused by excessive dietary iron intake .
What causes haemochromatosis?
.
One of the main causes of haemochromatosis is genetic. We then speak of so-called hereditary haemochromatosis. Its secondary variant, on the other hand, can be caused by selected medical treatments.
Hemochromatosis can be causedand:
-
anemia,
. -
long-term kidney dialysis,
.
-
hepatic diseasesand, such as steatosis or hepatitis C,
.
-
taking iron injections or tablets,
.
-
transfusions of blood,
- .
Symptoms
.
Hemochromatosis, the most common cause of excess iron, does not always produce specific symptoms. Some people may live with high iron concentrations and not even know it, while others will experience various manifestations of the excess.
Symptomsand excess iron in the body:
-
weakness,
. -
joint pains,
- pain.
-
fatigue,
- fatigue.
-
irregular heartbeat,
- confusion.
-
gastric pains,
- unresolved weight loss.
Effects
.
Excess iron can lead to numerous health problems. Most notably, it can result in arrhythmias and heart failure.
Negatively it also affects the liverand. It leads to its enlargement, failure in the course of cirrhosis and, in extreme cases, even cancer. Moreover, iron deficiency can also be the initiator of other diseases.
Other effectsand excess iron include:
-
diabetes,
. -
arthritis,
- diabetes,
-
erectile dysfunction,
- erectile dysfunction,
- erectile dysfunction.
-
premature menopause,
- premature menopause.
-
problems with the spleen, adrenal glands or thyroid gland,
.
-
grey skin,
What is the treatment of haemochromatosis?
The treatment of haemochromatosis primarily involves dietary changesand. Your specialist will certainly recommend that you stay away from products rich in this mineral. It's also worth limiting vitamin C, which increases iron absorption.
Another way to get rid of excess iron is therapeutic phlebotomy. This is a procedure that involves bleeding the blood, and therefore the iron it contains, from the patient's body. Iron concentration can also be lowered through the use of appropriate medication (oral or intravenous).
The concentration of iron in the body can be checked by a blood test. In turn, genetic tests, liver biopsy and MRI of selected organs will also be needed to make a diagnosis of haemochromatosis.
It is also possible to check the iron concentration in the body with a blood test.
Iron - supplementation
.
Iron is a mineral that is essential for our body to function properly. We should take it along with a balanced dietand, but sometimes it is necessary to support ourselves with supplements or medication. This is advisable in cases of iron deficiency or anaemia.
Indications for iron supplementation also include blood loss (internal bleeding, menstruation, medical procedures) and increased iron requirements (for example, during pregnancy).
How to increase absorption
.
Researchand suggests that certain compounds, most notably vitamin C, increase iron absorption. If you want to improve the absorption of iron in the body, supplement with products rich in this vitamin.
How long can you supplement?
.
You should not supplement large amounts of iron for more than 6 monthsand. Exceptions to this are other recommendations from your doctor. Remember that excess iron can go undiscovered for a long time, so don't take a 'supplement'.
What time of day to take?
.
Iron is best absorbed if taken on an empty stomachand. It is a good idea to sip them with water or fruit juice (preferably with vitamin C) about one to two hours before a meal.
People with gastrointestinal (especially gastric) conditions, on the other hand, should supplement iron deficiencies with food or immediately after finishing a meal. In this way, they will avoid stomach problems.
Note!
.If you are ill or taking other remedies (medication, supplements), do not use iron on your own. Check with your doctor before starting supplementation. He or she is the only one who can give you the green light for a healthy and safe supplementation.
Side effects

If you are experiencing these or the aforementioned symptoms, stop supplementation immediately and - if necessary - see your doctor.
Iron in pregnancy
.
The amount of blood in a woman's body increases during pregnancyand, so she needs more iron for herself and the yet-to-be-born baby. Deficiency of this mineral can result in an increased risk of anaemia in the mother-to-be, as well as a low birth weight baby .
What's more, a lack of adequate iron concentrations during pregnancy can lead to abnormalities in the development of the fetal central nervous system. Expectant women should take 27 mgand of iron each day.
Breastfeeding women
.
Deficiency of iron during infancy can result in later social withdrawal, concentration problems, and general developmental delay in the child . Despite this, the need for iron decreases after pregnancy, as the woman no longer keeps as much blood in her body then. Breastfeeding women should take 10 mg of iron daily.
Iron and alcohol
.
People suffering from alcohol disease often have higher body iron stores than othersand. Research indicates, that consuming even small doses of alcoholic beverages can significantly increase the risk of excess iron.
It doesn't stop there, higher iron content in the liver also increases the likelihood of cirrhosis of this organ.
Interactions of iron with drugs
.
Iron can interact with certain medications. Find out if you are at risk.
Iron canand react with:
-
tetracycline,
. -
penicillin,
-
cyprofloxacin,
-
medicines for the prevention of epileptic seizures,
-
medicines for the prevention of epileptic seizures.
Note!
.Iron can interact with over 80 drugsand. If you are taking any medications (drugs, supplements, herbs), ask your doctor's opinion before starting supplementation.

FAQ
.How to replenish iron in the body quickly
.Effective ways to replenish iron deficiencies are:
.- including sources of iron in the daily diet (e.g. red meat, seafood, dark green leafy vegetables, dark chocolate, whole grain products) and vitamin C, which improves absorption;
- safe iron supplementation. .
You will need to wait at least a few weeks for the effects.
.The quickest way to raise blood iron levels - especially in cases of severe anaemia - is an intravenous infusion along with vitamin C, but this treatment is decided by your doctor, based on the results of blood tests.
What leaches iron?
.There are several substances that can reduce the absorption of iron or, by binding it together, indirectly leach it from the body. The most important of these are:
- phytates - found in cereals, almonds, legumes and tofu, .
- polyphenols - found in soya, green tea, red grapes or beans, .
- calcium and phosphorus - reduce iron absorption from plants, .
- zinc - large amounts can inhibit iron absorption and assimilation, .
- carbs - bind iron and increase its excretion from the body; plenty of these in coffee, tea and red wine, .
- caffeine, .
- magnesium - do not supplement magnesium and iron at the same time.
Is iron deficiency dangerous?
.Yes. Iron is essential for the production of haemoglobin, which transports oxygen from the lungs to the tissues. Iron deficiency leads to anaemia, which results in oxygen deficiency and weakness throughout the body. It can cause fatigue, weakness, shortness of breath, headache, dizziness, cold extremities and other severe symptoms.
In children and pregnant women, iron deficiency can lead to irreversible developmental disorders. In severe cases, iron deficiency can lead to an increased risk of heart attack and damage to the brain and immune system.
How does iron affect hair?
.Iron deficiency in the body can lead to shrinkage of hair follicles and delay the production of new, healthy hair, as well as leading to weakness and hair loss. In addition, iron is important for the production of melanin, which is the pigment of hair and skin, so iron deficiency negatively affects the appearance and condition of hair.
.Does stress affect iron levels?
.Yes, prolonged stress can affect iron levels in the body. Stress hormones such as cortisol and adrenaline increase the excretion of iron from the body, which can lead to iron deficiency. In addition, stress can alter eating habits, and an unhealthy diet can lead to reduced iron intake and absorption. Stress can also lead to digestive diseases, which will negatively affect iron absorption.
Therefore, it is important to manage stress and maintain a healthy lifestyle, which includes a healthy diet and regular physical activity, to maintain healthy iron levels in the body.

Why an iron-rich diet is important for girls and women?
.Firstly, women are at greater risk of iron deficiency due to blood loss during menstruation. Chronic iron deficiency can lead to anaemia, which manifests as fatigue, shortness of breath and weakness.
Secondly, pregnant women are advised to increase their iron intake to ensure an adequate amount for the baby's development. Iron deficiency in pregnancy can lead to preterm birth, low birth weight of the baby and various complications.
Iron deficiency in pregnancy can lead to preterm birth, low birth weight of the baby and various complications.
Can you take iron with vitamin B12?
.There is no contraindication to taking iron along with vitamin B12. Research suggests that both compounds are helpful in treating anaemia. An iron-rich diet is important for hair and skin health because iron is essential for the production of keratin, a protein found in hair, skin and nails.
