Top 10 Best Iron Supplements for Low Ferritin

Written by Andrew Le, MD

UpdatedAugust 27, 2024

Iron is an important mineral that has a major function in the human body. It plays a role in the creation of red blood cells, which transport oxygen to the various body tissues. Lack of iron leads to a medical condition called anemia that occurs when the body has a low number of red blood cells used in the transport of oxygen. The primary reason for anemia is low ferritin which is the protein that is responsible for the storage of iron.

Iron supplements can also be used to help build up the body’s stores of iron and manage anemia. However, given the existence of a large number of brands and forms of iron supplements, the choice will not be easy.

That’s why we have prepared a list of the best iron supplements that can boost your iron levels and become beneficial for your body. In the subsequent part of this article, we will explain the functions and advantages of this supplement, as well as why it is the best option for everyone who wants to raise their iron levels.
