Feeling tired or low on energy? You might not be getting enough iron in your diet. Iron is a vital mineral that supports the development of healthy blood and is crucial for overall well-being. Iron deficiency anemia is the most common nutritional deficiency globally, leading to severe exhaustion and dizziness. It affects people of all ages, but children, pregnant women, menstruating women, and dialysis patients are at higher risk.
What is the Importance of Iron?
Iron is a key component of hemoglobin, a protein in red blood cells that transports oxygen throughout the body. Without enough iron, you lack red blood cells to carry oxygen, causing fatigue. Iron also supports myoglobin, which stores oxygen in muscle tissues, and is essential for brain development in children, growth, and hormone function.

What Are Iron Supplements?

Ferrous sulphate
Ferrous gluconate
Ferric citrate
Ferric sulphate
Note: Consult a doctor before starting any supplement.
Iron-Rich Foods:
Iron is found in two forms: heme (from animal sources) and non-heme (from plant sources). Heme iron, found in meat, poultry, and seafood, is more easily absorbed than non-heme iron, which is in plant foods.
Animal-Based Sources:
Meat organ meats (liver, spleen)
Poultry
Fish or shellfish (salmon, sardines, tuna)
Eggs
Plant-Based Sources:
Nuts and seeds (gingelly seeds, cashew nuts, almonds)
Dried fruit (dates, figs)
Whole grains and millets
Iron-fortified cereals
Legumes (kidney beans, lentils, chickpeas)
Dark leafy greens (spinach, kale, mint)
How Can We Take Iron-Rich Supplements?
To maximise absorption, take iron supplements on an empty stomach, ideally one hour before a meal, with a vitamin C-rich beverage like orange juice.
Importance of Iron-Rich Supplements:
To avoid inhibiting iron absorption, avoid food, tea, and milk one hour before and after taking supplements. Some medications, such as antacids and antibiotics, can also affect absorption. Vitamin C enhances iron absorption, so pair your supplement with a vitamin C-rich drink.
When to Take Iron Supplements:
When to take iron tablets: Follow your doctor's advice. Generally, iron is best taken on an empty stomach to enhance absorption.
