To help you out, here are a few tips on choosing the best iron supplements for you.

How To Choose The Best Iron Supplements

Supplement Type

Iron supplements are available in different forms, liquid, capsule, or tablets. Some people might have a hard time swallowing non-chewable pills, whereas some worry that liquid supplements can stay in their teeth. You can consult your doctor for the exact type of dosage and recommendation in terms of your iron supplement.


Excessive doses of iron can be too toxic for your liver, and give rise to serious health problems. The ideal way to understand the optimal dosage of an iron supplement is to have proper blood tests done by a doctor. You can determine the iron supplement as per the dosage instructions from your physician. Generally, it is recommended that adult females take 18 MG of iron supplement per day, whereas for adult males it is 8MG. For pregnant women the recommended amount of daily iron supplement is 27MG. However, consult your doctor before committing on a fixed dosage.

Iron Level

Supplements are commonly sold under the names ferrous fumarate, ferrous sulfate, and ferrous gluconate. This can confuse you especially due to the basis of the amount of iron displayed on the label. All the three forms of iron can be absorbed by the body well, but there is a difference in the elemental iron levels. For instance, ferrous fumarate contains the highest level of elemental iron, but it can be too much of a dosage for some.

Explore these iron supplements to improve your iron levels and rebuild energy in your system. But before you do so, please check with your health care provider. They will be able to recommend the right supplement for you.
