Iron deficiency (ID) and iron deficiency anemia (IDA) seriously affect the prognosis of chronic diseases such as cancer, digestive system diseases, chronic kidney disease, and heart failure.
Iron supplementation is an important treatment for iron deficiency and iron-deficiency anemia. Iron supplements are classified into inorganic iron and organic iron; and according to the route of administration, they are classified into oral iron and intravenous iron. Iron supplementation treatment needs to take into account the patient’s hemoglobin (Hb) level, tolerance to oral iron supplements, and comorbidities that affect iron absorption.
This article will provide the ultimate guide to iron drops, including their efficacy, suitable users, and side effects.
What are Iron Drops?
The importance of iron
Iron is an essential mineral for human growth and development. Our bodies use iron to produce hemoglobin and myoglobin. Iron is also an indispensable raw material for the synthesis of certain hormones.
Iron deficiency means low hemoglobin levels, which can lead to anemia, fatigue, weakness, increased susceptibility to disease, and other symptoms. Iron is also essential for optimizing brain function.
Classification of iron supplements
Iron supplements are mainly divided into two categories: inorganic iron and organic iron.
Inorganic iron (such as ferrous sulfate): It is inexpensive, but has a low absorption rate (about 10%) and can easily cause side effects such as constipation and nausea.
Organic iron (such as ferrous gluconate, ferrous fumarate, polysaccharide iron complex, etc.): has a higher absorption rate (15%-35%), less gastrointestinal irritation, and is suitable for sensitive people.
New types of iron supplements (such as microencapsulated iron and heme iron) have high absorption rates and fewer side effects, but are more expensive.
Iron drops
Iron Drops refers to liquid iron supplements. They are primarily used to prevent and treat iron-deficiency anemia. Their key advantages are flexible dosage, ease of administration, and rapid absorption.
Physiological functions of iron
(1) It constitutes hemoglobin and participates in oxygen transport.
More than 70% of the iron in the human body is found in hemoglobin, where it is the active factor and participates in the transport and exchange of oxygen and carbon dioxide.
(2) It constitutes cytochromes and iron-containing enzymes, and participates in energy metabolism.
Iron is a cofactor of cytochrome enzyme systems in cells and tissues, playing an important role in biological oxidation processes. At the same time, iron is also an activator of iron-containing enzymes in the human body, participating in many important metabolic activities such as collagen synthesis and lipid transport.
(3) Maintaining the body’s normal immune function and anti-infection ability
Iron can promote the synthesis of immune factors such as proteins and interleukins in the liver, spleen, and thymus, and has a direct impact on non-specific immunity such as humoral immunity, cellular immunity, and phagocytosis. It can also promote drug detoxification in the liver.
Common symptoms of iron deficiency
Infants and teenagers: Frequent crying, waking up in the middle of the night, lethargy, loss of appetite, picky eating, delayed growth and development, frequent dizziness, insomnia, colds, fever, cough, diarrhea, poor concentration, poor comprehension and memory, poor academic performance;
Women: pale or sallow complexion, bloodless lips, dull hair, insomnia and excessive dreaming, weakness in the limbs, aversion to cold, scanty menstruation, amenorrhea or heavy menstruation, dysmenorrhea, skin prone to wrinkles and age spots, and prone to oral ulcers.
For women, combating fatigue hinges on iron supplementation: Most people consider fatigue a normal physiological response; however, the perception of fatigue varies from person to person, with women experiencing fatigue three times more often than men. Iron deficiency anemia is highly prevalent among women of childbearing age, and anemia is a significant cause of fatigue syndrome. Mild iron deficiency anemia manifests as easy fatigue, poor concentration, sensitivity to cold, and decreased immunity.
The amazing benefits of Iron Drops
01. Replenish Qi and Blood
Iron can form heme, thus it has the function of replenishing blood.
02. Boost immunity
If the body does not have enough iron to maintain hemoglobin, it will be more susceptible to illness and its resistance will decrease.
03. Refreshing
Iron’s primary function is to supply oxygen to the body’s cells and tissues. Insufficient oxygen supply can lead to problems such as drowsiness and fatigue.
04. Skin Beautification
Adequate iron intake promotes brighter and firmer skin.
05. Nail Art
When a person has sufficient iron intake, their nails are less prone to splitting and will be bright and resilient.
06. Effects on the respiratory system
If the body does not have enough iron to maintain hemoglobin, it will be more susceptible to illness and its resistance will decrease.
07. Infant Intellectual Development
If a woman does not get enough iron, it can affect the normal development of the fetus’s intelligence and even cause insufficient blood supply to the fetal brain.
How to choose Iron Drops?
For infants and young children, liquid iron supplements should be chosen. In addition to price, the main factors to consider are iron content, absorption rate, side effects, and taste.
The most commonly used iron supplements are ferrous salts, including ferrous sulfate, ferrous gluconate, and ferrous fumarate.
Ferrous iron (Fe²⁺) is more soluble than dietary iron (Fe³⁺) and has twice the absorption capacity. The estimated absorption rate of ferrous salts is 10% to 15%, and in a small but randomized controlled trial, there was no difference in the absorption capacity of several ferrous preparations.
While higher iron content makes iron supplementation more effective, it may increase side effects. Common side effects include constipation, diarrhea, heartburn, nausea, and upper abdominal pain. Taking iron with meals can reduce gastrointestinal discomfort, but this can affect absorption.
Possible side effects
Potential side effects of excessive iron intake include:
1. Cancer
Especially rectal cancer.
2. Liver disease
For example: liver scar tissue, liver cirrhosis caused by liver inflammation.
3. Heart disease
Too much iron in the body can cause rust, which in turn corrodes internal organs.
4. Low testosterone levels
5. Low libido
6. Diabetes
7. Chronic fatigue syndrome
8. Infertility
9. Neurodegenerative diseases
10. Inflammatory diseases
Iron deficiency is one of the most common mineral deficiencies, but at the same time, excessive iron intake can also be dangerous.
FAQ
What are iron drops used for?
It can improve anemia, enhance immunity, promote growth and development, and improve blood circulation.
Are iron drops better than pills?
There is no inherent superiority of iron drops over iron tablets; they are suitable for different groups of people and for different situations. Iron drops are suitable for children, people with swallowing difficulties, and those who require low-dose supplementation.
What should not be taken with iron supplements?
Milk, calcium supplements, and antacids can all interfere with iron absorption. If you eat these foods, it’s best to wait at least two hours between taking iron supplements and consuming them.
The polyphenols and tannins in tea and coffee can also affect iron absorption, so it’s best to avoid strong tea and coffee.
Conclusion
Appropriate iron supplementation can help boost immunity and also aid in the metabolism of proteins and fats, as well as the synthesis of nucleic acids. It can also promote the absorption of minerals such as calcium and zinc.
