Which mineral is primarily responsible for transporting oxygen?

Iron is primarily responsible for transporting oxygen in the body. This essential mineral is a key component of hemoglobin, the protein found in red blood cells that binds to oxygen in the lungs and carries it throughout the body to tissues and organs. The presence of iron allows hemoglobin to effectively pick up oxygen and release it where it's needed for cellular respiration and energy production.

Without adequate iron levels, the body's ability to transport oxygen can be significantly impaired, leading to fatigue and decreased physical performance. This relationship between iron and oxygen transport is crucial, especially for athletes and individuals engaged in regular physical activities, as they have higher demands for oxygen due to increased physical exertion.
