Iron is a vital mineral that supports oxygen transport, energy production, and immune function. Tortillas, a staple in many diets, can contribute meaningful amounts of iron depending on the type and portion. This calculator helps you estimate the iron content in your tortilla servings, whether you're tracking daily intake, planning meals, or managing iron deficiency.
Simply choose the tortilla type (flour, corn, whole wheat, or spinach), enter the number of tortillas or the total weight, and optionally adjust for enrichment. The tool provides a clear breakdown of iron per serving and per 100 grams, along with a comparison to the recommended daily allowance. Perfect for dietitians, fitness enthusiasts, and anyone curious about their micronutrient intake.

How to Use This Tool
Select your tortilla type from the dropdown — flour, corn, whole wheat, or spinach. Then choose whether you want to calculate based on the number of tortillas or the total weight in grams. If you know the number, enter it; the calculator will estimate the weight using typical serving sizes. If you prefer weight, enter the grams directly. The enrichment toggle is on by default for flour tortillas, reflecting common fortified products. Click "Calculate Iron" to see your results, including total iron, iron per 100 g, and the percentage of the daily value. Use the quick-fill buttons for common portions like 1, 2, or 3 tortillas, or 100 g.
How It Works
The calculator uses average iron values per 100 grams for each tortilla type, based on USDA FoodData Central data. For flour tortillas, the base value is 4.0 mg per 100 g, which is typical for enriched versions. Corn tortillas average 1.7 mg, whole wheat 3.6 mg, and spinach tortillas 2.9 mg. When you enter a number of tortillas, the calculator multiplies by a typical weight per tortilla (60 g for flour, 50 g for corn, 60 g for whole wheat, 55 g for spinach) to estimate total weight. Then it applies the formula: iron (mg) = (iron per 100 g × weight in grams) / 100. If the enrichment toggle is on and you selected flour, the result is multiplied by 1.5 to account for added iron. The daily value used is 18 mg, based on FDA guidelines for adults.
Worked Examples
Example 1: You eat 2 flour tortillas with enrichment. Each weighs 60 g, so total weight = 120 g. Iron = (4.0 × 120) / 100 = 4.8 mg. With enrichment factor 1.5, total = 7.2 mg. That's 40% of the daily value.
Example 2: You have 100 g of corn tortillas. Iron = (1.7 × 100) / 100 = 1.7 mg. That's about 9.4% of the daily value.
Example 3: A spinach tortilla wrap (55 g) without enrichment. Iron = (2.9 × 55) / 100 = 1.6 mg.
Tips & Best Practices
- Check the nutrition label on your tortilla package — actual iron content can vary by brand and recipe.
- If you're tracking iron for anemia, consider pairing iron-rich foods with vitamin C (like salsa or citrus) to enhance absorption.
- Whole wheat and spinach tortillas offer more fiber and micronutrients than refined flour, but enriched flour tortillas often have higher iron due to fortification.
- Use this calculator as an estimate, not a medical recommendation. For personalized advice, consult a registered dietitian.
Factors Affecting Accuracy
Iron content can vary significantly between brands, especially for flour tortillas. Some are enriched with iron and B vitamins, while others are not. The typical weights used here are averages; actual tortillas may be larger or smaller. Homemade tortillas may have different iron levels depending on the flour used. Always refer to the product's nutrition facts panel for the most precise values.
Frequently Asked Questions
Are corn tortillas a good source of iron?
Corn tortillas provide about 1.7 mg per 100 g, which is moderate. They are not as high as enriched flour tortillas, but they are naturally gluten-free and often paired with beans, which are also iron-rich.
How does iron from tortillas compare to other foods?
For reference, a 100 g serving of cooked spinach has about 3.6 mg of iron, similar to whole wheat tortillas. Red meat is much higher, with about 2.7 mg per 100 g, but the heme iron in meat is absorbed more efficiently.
Can I use this calculator for other flatbreads?
The values are specific to tortillas, but you can approximate for similar products like pita or naan by adjusting the weight and using a comparable iron value. For precise data, check the USDA FoodData Central database.
