Best Iron Supplement For Iron Deficiency

What is Iron Used for in the Body?

Iron is an essential mineral and it plays a crucial role in your body. Red blood cells carry oxygen from your lungs to cells throughout your body. Hemoglobin is the component that carries this oxygen in your red blood cells. You need iron to make hemoglobin, which means you need iron to help your body get the oxygen it needs. Without enough iron, your body won’t have enough hemoglobin, and you may feel tired. In more severe cases, you may be diagnosed with iron deficiency anemia. To manage this condition, you healthcare practitioner may ask you take the best iron supplement for iron deficiency.

What is Iron Deficiency Anemia and What Causes it?

Iron deficiency anemia (IDA) is anemia caused by a lack of iron. Anemia is a condition where you don’t have sufficient healthy red blood cells to get enough oxygen to your body cells. Some of the causes of IDA are:

  • Not consuming enough iron
  • Menstrual bleeding
  • Pregnancy

Iron deficiency is one of the most common nutritional deficiencies in the world. If you think you may have the symptoms of iron deficiency, it is important to talk to your family doctor.

What are the Symptoms of IDA and How to Reduce Them?

The symptoms of IDA can be mild at first. People with IDA can feel very tired and weak. The other symptoms of IDA include:

  • Feeling cold
  • Brittle nails
  • Headaches
  • Feeling dizzy
  • Shortness of breath
  • Quick heart rates

Including more iron rich foods in your diet can help with IDA. Along with dietary changes, iron supplements can help as well. Talk to your physician to check your iron levels and if they are low, ask about iron supplements.

How Much Iron Should I Consume Per Day?

The amount of iron you should consume a day depends on your age and gender. Older women and pregnant women need the most iron. People who are vegetarian are also recommended to include more iron in their diet than people who eat meat.

The recommended amount of iron you should get from your diet is around 8-18 mg a day for healthy adults. If you are trying to include more iron in your diet, then you need to know that there are two types of iron that you can get from food: heme iron and nonheme iron. Heme iron is easier to absorb than non-heme iron. You usually get heme iron from meat and nonheme iron from vegetables, nuts, and grains. If you can’t get enough iron from your diet, you may need iron supplements.

Iron Supplements for Iron Deficiency Anemia

Iron deficiency can range from mild to severe enough to cause anemia. IDA can be treated by consuming more iron-rich foods or by taking iron supplements. Iron supplements increase the amount of iron in your blood, and there are heme and non-heme ones.

While iron supplements can be purchased without a prescription, you should still consult a doctor as there are many different types of iron supplements on the market. A few of the available iron supplements are:

  • Multivitamin supplements that also have iron
  • Iron supplements with ferrous or ferric iron salts
  • Heme iron polypeptides, or carbonyl iron

Iron supplements can come as a powder, a liquid, a pill, or a chewable pill depending on what you need and what your doctor recommends. To treat IDA, you may need to take iron supplements for three months, as it may take a while to replenish your iron stores. It is always recommended that you speak to your doctor for individualized guidance about iron supplementation.

Best Iron Supplement for Iron Deficiency for Women

There are many brands and types of iron supplements available for women. These supplements come in various doses, prices, and have different forms of iron. Although there are many recommendations about iron supplementation, if you have iron deficiency, you need an iron that absorbs easily and increases your iron stores.   Women are more likely to have iron deficiency than men. Given this, it is recommended to consult your family doctor about your iron levels. If tests reveal that your iron levels are low, talk to your doctor about heme iron supplements.
