Iron is an essential mineral that helps transport oxygen, support energy production, and maintain a healthy immune system. Pairing iron-rich foods with vitamin C-rich foods can help your body absorb more iron, particularly from plant sources. Use this guide to understand your iron needs, meet them through food, and explore the role of vitamin C in supporting iron absorption.
Daily Iron Requirements
Adult women (19-50 years): 18 mg per day
Adult women (51+ years): 8 mg per day
Pregnant women: 27 mg per day
Breastfeeding women: 9-10 mg per day
Daily Vitamin C Requirements
Adult women: 75 mg per day
Pregnant women: 85 mg per day
Breastfeeding women: 120 mg per day
Smokers: Add an extra 35 mg per day to the above amounts
Low Iron? Try This!
When iron levels drop, you may need 150-200% of the recommended daily intake (often 15-30 mg per day or more, depending on severity). Always consult with your registered dietitian to provide personalized guidance, as they may recommend supplementation alongside dietary changes.
Focus on heme iron sources (animal-based foods) which are absorbed 2-3 times more efficiently than plant-based (non-heme) iron
Pair non-heme iron foods with vitamin C-rich foods to enhance absorption
Avoid coffee, tea, and calcium-rich foods around iron-rich meals, as they can inhibit absorption
Cook in cast iron cookware to increase iron content in your meals
Get your levels tested regularly to monitor progress
Consider supplementation if recommended by your healthcare provider
Iron-rich Foods
Each item shows the serving size (in cups, ounces, or tablespoons) and weight in grams. For example, beef liver (3 oz/85g) - 5.5 mg iron. This means that 3 oz of beef liver (which weighs 85 grams) contains 5.5 mg of iron.
Absorption Tip
Pair non-heme iron foods (plants, legumes, grains, nuts, seeds) with vitamin C sources (citrus, peppers, strawberries) to increase iron absorption up to 3-6×.
