Iron is an essential mineral that plays a critical role in various physiological functions, including oxygen transportation, DNA synthesis, and energy production. As women age, their nutritional needs change, and iron intake must be adjusted accordingly. While iron deficiency remains a concern for some older adults, excessive iron intake can pose significant health risks. Understanding whether 65 mg of iron a day is too much is essential in maintaining optimal health in women over 70.

Iron is a fundamental mineral required for numerous biological functions, including oxygen transport, energy production, and immune system support. It plays an essential role in the formation of hemoglobin, the protein in red blood cells responsible for carrying oxygen throughout the body. However, iron must be stored efficiently for the body to maintain a steady supply. This is where ferritin, a specialized iron-storage protein, becomes crucial. Ferritin acts as a reservoir for iron, ensuring that the body has an adequate supply when needed. If ferritin levels are too low, iron deficiency can develop, leading to fatigue, cognitive impairments, and weakened immunity.
