Iron supplements are products designed to increase the levels of iron in the body. They are often used to treat or prevent iron deficiency anemia, a condition where the body lacks enough iron to produce adequate hemoglobin, the protein in red blood cells that carries oxygen. These supplements come in various forms, including tablets, capsules, and liquids. Taking iron supplements can help improve energy levels and overall health, especially for individuals at risk, such as pregnant women, vegetarians, and those with certain medical conditions. However, it's important to consult a healthcare provider before starting any supplement to ensure proper dosage and avoid potential side effects.
