Ten Reasons Your Hemoglobin Might Be Low

4. Iron Deficiency

Extreme fatigue, shortness of breath, weakness, brittle nails, and unusual cravings (ice, dirt, starch, etc.) are signs of low hemoglobin levels caused by an iron deficiency. The most common is a diet lacking in iron. The addition of iron-rich foods such as beef, eggs, leafy green vegetables, brown rice, and peanut butter can have a profound effect on hemoglobin levels. Adding foods rich in vitamin C will enhance the absorption of iron.
