Iron is an essential mineral that supports oxygen transport and energy production in the body. It’s a critical component of hemoglobin, the protein in red blood cells responsible for delivering oxygen to tissues, and myoglobin, which helps muscle cells store and use oxygen efficiently. Iron also plays a role in ferritin, the body’s main iron storage protein, found in the liver, spleen, and intestines. Adequate iron levels are especially important for women of childbearing age, as they are linked to reduced fatigue, enhanced cognitive performance, and improved mood. Without sufficient iron, the body struggles to maintain energy, focus, and physical endurance. Supplementing with iron can help restore balance and support overall well-being, especially in individuals with increased needs or low dietary intake.
