- Also, iron absorption is impaired by drinking tea. Studies show that tea inhibits iron absorption. Drinking a lot of black and green tea can cause anemia (iron deficiency).
- Plus, caffeine drinks reduce iron absorption. For that reason, take iron at least a couple of hours after or before caffeinated foods.
- As well, a study shows that iron absorption falls by drinking alcohol.
Usually, iron supplements are prescribed for a limited time (a few months). That is to avoid further health issues, for example, liver and stomach damages.

How to Check Iron Levels at Home?
Since hemoglobin levels and oxygen levels are tightly related to each other, you can check iron levels at home with a hemoglobin testing kit.
Low oxygen levels can be a sign of low levels of iron. That’s why tiredness or difficulty in breathing are symptoms of iron deficiency anemia.
When your organs can’t get enough oxygen because of a low level of hemoglobin, the respiratory rate will increase to get more oxygen.
But, visit a doctor for tests such as serum iron test and transferrin test to measure proper iron levels.
