Iron is an essential mineral that supports oxygen transport, energy metabolism, and immune function. Couscous, a staple grain in North African cuisine, provides a modest but meaningful amount of iron — especially when paired with vitamin C-rich foods. This calculator helps you estimate the iron content in your couscous serving based on portion size and type.
Whether you're tracking micronutrients for a balanced diet, managing iron intake for athletic performance, or simply curious about the nutritional profile of your meals, this tool gives you a quick, reliable estimate. Use it alongside other nutrition calculators to build a complete picture of your daily intake.

How to Use This Tool
Using the Couscous Iron Calculator is straightforward. Start by entering your serving size — you can specify the amount in grams, ounces, or cups. Then select the type of couscous: regular cooked, whole wheat cooked, or dry uncooked. The calculator uses standard iron density values per 100 grams for each type. Click "Calculate Iron" to see the total iron content, along with a breakdown showing the serving weight in grams and the iron density used. Use the preset buttons for quick common servings like 100g regular or 1 cup regular.
How It Works
The calculation is based on the iron content per 100 grams of couscous. For regular cooked couscous, the iron content is approximately 0.6 mg per 100g. Whole wheat couscous contains slightly more — about 0.8 mg per 100g — because the bran and germ retain more minerals. Dry uncooked couscous has a higher density of iron (around 1.1 mg per 100g) because water has not been added. The formula is simple: Total Iron (mg) = (Serving Weight in grams / 100) × Iron per 100g. The tool converts your chosen unit (oz or cup) to grams using standard conversion factors: 1 oz = 28.3495 g, and 1 cup of cooked couscous ≈ 157 g.
Example Calculations
Example 1: You eat 1 cup (240 ml) of regular cooked couscous. Using the conversion 1 cup ≈ 157 g, the iron content is (157 / 100) × 0.6 = 0.94 mg. That's about 5% of the daily recommended intake for adult women (18 mg) and 12% for adult men (8 mg).
Example 2: You prepare 150 g of dry couscous (uncooked). The iron content is (150 / 100) × 1.1 = 1.65 mg. Note that dry couscous expands when cooked, so 150 g dry yields roughly 350–400 g cooked.
Tips for Maximizing Iron Absorption
Iron from plant sources (non-heme iron) is less easily absorbed than iron from meat. To boost absorption, pair your couscous with vitamin C-rich foods such as bell peppers, tomatoes, lemon juice, or broccoli. Avoid drinking tea or coffee with your meal, as tannins can inhibit iron absorption. Cooking in a cast-iron skillet can also add a small amount of dietary iron.
Factors Affecting Accuracy
The iron values used are averages from standard nutrition databases (USDA FoodData Central). Actual iron content can vary based on the brand, cooking method, and water quality. Whole wheat couscous generally has higher mineral content, but the difference is modest. If you need precise values for medical or clinical purposes, consult a registered dietitian or use laboratory analysis.
Frequently Asked Questions
Is couscous a good source of iron? Couscous provides a moderate amount of iron — about 0.6–1.1 mg per 100g. It can contribute to your daily intake, especially when combined with other iron-rich foods like lentils, spinach, or red meat. For reference, the recommended daily allowance is 8 mg for adult men and 18 mg for women of childbearing age.
Does cooking method affect iron content? Boiling couscous in water does not significantly change its iron content, but the water dilutes the concentration. Dry couscous has a higher iron density per gram because it hasn't absorbed water. Once cooked, the weight increases but the total iron remains the same, so the mg per 100g decreases.
Can I use this calculator for other grains? This tool is specifically calibrated for couscous. For other grains like quinoa, rice, or bulgur, you would need different iron density values. Check our quinoa nutrition calculator for similar tools.
