What is Iron?

Iron is a vital mineral that your body needs for growth, development, and overall function. It plays a key role in making hemoglobin, a protein in red blood cells that carries oxygen throughout the body, and myoglobin, which helps muscles store oxygen.

Iron can be found in two main forms in foods: heme and non-heme. Heme iron, the most easily absorbed form, is found in animal products like red meat, poultry, and fish. Non-heme iron is found in plant-based foods like beans, lentils, spinach, and fortified cereals.

Your body uses iron for energy production, oxygen transport, and maintaining healthy cells and tissues. It's also essential for proper immune system function and brain development, especially during growth periods.

Why Iron Matters

⚡

Boosts Energy Levels

Iron helps your red blood cells deliver oxygen to tissues, which supports energy production. Low iron can lead to fatigue and decreased physical performance.

🧠

Supports Cognitive Function

Adequate iron is critical for brain function and development. It helps maintain focus, memory, and learning, especially in children and young adults.

🛡️

Strengthens Immune System

Iron is crucial for a healthy immune system. It aids in the production of white blood cells, which help your body fight infections more effectively.

🤰

Promotes Healthy Pregnancy

Iron needs increase during pregnancy because it supports the growth of the baby and placenta. Adequate iron reduces the risk of low birth weight and preterm delivery.
