Vodka is one of the few alcoholic drinks that is essentially free of iron. Because distillation removes nearly all minerals, a standard shot of 80-proof vodka contains only about 0.004 mg of iron — less than 0.1% of the average adult woman's daily need. However, the mixers you add can change that picture dramatically: tomato juice, orange juice, and cranberry juice all contain measurable iron.
This vodka iron calculator estimates the iron supplied by plain vodka and common vodka-based drinks, then compares it to standard daily iron targets for adult men, women, pregnant women, and teens. You choose the drink type, serving size, and number of servings, and the tool instantly returns iron per serving, total iron, and the percentage of your daily target.
Use it when logging meals, planning a diet around iron needs, or simply checking whether your favorite cocktail belongs in an iron-conscious meal plan. For overall drink nutrition, pair it with our drink nutrition calculator.
🥃 Vodka Iron Calculator
Estimate the iron content of vodka and vodka-based drinks, and see how it fits your daily iron target.
How It Works: From Shot to Milligrams
The calculator uses a straightforward proportion:
Total iron (mg) = drink volume (ml) × number of drinks × iron per 100 ml ÷ 100
For a single 250 ml vodka tonic with an iron value of 0.02 mg per 100 ml, the math is 250 × 0.02 ÷ 100 = 0.05 mg. Multiply by the number of drinks you enter, then divide by your chosen daily iron target to get the percentage of daily value.
The iron-per-100 ml figures are estimates based on typical cocktail proportions and USDA FoodData Central reference values for vodka, tomato juice, orange juice, cranberry juice, tonic water, and soda water. Because distillation removes essentially all minerals, plain vodka sits at the bottom of the table. Nearly all of the iron in a vodka mixture comes from the mixer, not the spirit itself.

Reference Table: Iron in Common Vodka Drinks
Values below are estimates for standard recipes using 80-proof vodka and typical mixers. Your actual drink may differ depending on proportions and brand.
| Drink | Main mixer | Est. iron (mg / 100 ml) | Standard serving |
|---|---|---|---|
| Plain vodka (80 proof) | None | 0.01 | 44 ml shot ≈ 0.004 mg |
| Vodka & soda | Carbonated water | 0.01 | 250 ml highball ≈ 0.03 mg |
| Vodka tonic | Tonic water | 0.02 | 250 ml highball ≈ 0.05 mg |
| Screwdriver | Orange juice | 0.10 | 250 ml highball ≈ 0.25 mg |
| Cosmopolitan | Cranberry juice | 0.15 | 120 ml cocktail ≈ 0.18 mg |
| Bloody Mary | Tomato juice | 0.25 | 250 ml glass ≈ 0.63 mg |
Worked Examples
Example 1: Sunday Bloody Mary
You drink two Bloody Marys, each 250 ml. At 0.25 mg per 100 ml, each drink provides 250 × 0.25 ÷ 100 = 0.625 mg. Two drinks give 1.25 mg. For an adult woman with an 18 mg target, that is 1.25 ÷ 18 × 100 = 6.9% of the day's iron. It will not replace a meal, but it is not completely negligible.
Example 2: Nightcap Vodka Tonic
One 250 ml vodka tonic at 0.02 mg per 100 ml contains 250 × 0.02 ÷ 100 = 0.05 mg. Against an adult male target of 8 mg, that is only 0.6%. Nutritionally, it behaves like the vodka itself: essentially iron-free.
Common Misconceptions
- “Vodka contains iron.” Distilled spirits contain only trace minerals. A standard shot of 80-proof vodka provides roughly 0.004 mg iron, which is below the rounding threshold on nutrition labels.
- “Clear drinks have no nutritional impact.” The mixer is the main character. A screwdriver made with real orange juice contributes measurable iron, vitamin C, and potassium, while vodka and soda contributes almost nothing.
- “Dark or red mixers always mean more iron.” Not necessarily. Cola and many red syrups are very low in iron, while tomato juice is genuinely higher. Use the reference table instead of color clues.
- “Alcohol can be your iron supplement.” It cannot. Regular heavy drinking can actually interfere with nutrient absorption and liver function, so it should never be used as a way to boost iron intake.
Limitations and Precision Notes
These estimates are useful for diet tracking, but they are not lab measurements. Recipes vary: some Bloody Marys contain clam juice or beef broth, which can change iron content. A Cosmopolitan made with a splash of cranberry juice differs from one made with equal parts mixer. Ice dilution changes volume but not the iron concentration of the liquid you pour.
Iron targets also vary. The standard 18 mg figure applies to premenopausal women, while adult men need only 8 mg. Pregnancy raises the target to 27 mg, and people following vegetarian or vegan diets may need up to 1.8 times the standard amount because plant iron is less bioavailable. The National Institutes of Health provides a full breakdown of iron recommendations by age and life stage.
Frequently Asked Questions
Can vodka help with anemia? No. Even several servings of plain vodka would provide far less than 0.1 mg of iron, while a typical iron supplement contains 15–65 mg. Iron-rich foods like lentils, spinach, red meat, and fortified cereals are the practical options.
Why does my calculator show iron for a Bloody Mary? Because tomato juice naturally contains around 0.3–0.5 mg per 100 ml, depending on the brand. After dilution with vodka and seasonings, the drink lands near 0.25 mg per 100 ml in our estimate.
Does flavored vodka change the iron content? Usually not by much. Flavored vodkas are still distilled spirits, and any added flavorings are generally added in tiny amounts. The mixer you choose matters far more.
Can I track calcium in cocktails too? Yes — if you are interested in another mineral, the cocktail calcium calculator works the same way for calcium in mixed drinks.
