Most people think about sugar and alcohol when sizing up a cocktail, but the mixers matter nutritionally too. A Bloody Mary can deliver a meaningful amount of potassium from tomato juice, while a fresh orange juice screwdriver carries roughly 360 mg in a standard glass. This cocktail potassium calculator estimates the potassium content of a drink from its measured juice, mixer, and cream ingredients, so you can compare recipes, build a lower-potassium drink, or track micronutrients without digging through nutrition databases.
Select a classic recipe or enter your own ingredients, adjust the amounts in milliliters or fluid ounces, and see the total potassium, its percentage of the Daily Value, and a low/moderate/high classification. Results are shown per serving and can be scaled for batch pitchers or party punches.
🍸 Cocktail Potassium Calculator
Estimate the potassium contributed by the juices, mixers, and creamy ingredients in your favorite cocktail.
How the Estimate Is Calculated
Potassium numbers in this calculator come from approximate values in the USDA FoodData Central database for commonly used juices and mixers. The calculation assumes a simple proportional relationship: if a juice contains about 200 mg of potassium per 100 ml, then 50 ml supplies 100 mg, and 180 ml supplies 360 mg. For each of the three mixer rows, the tool converts fl oz to milliliters (1 fl oz = 29.5735 ml), multiplies the volume by the ingredient's potassium density, and adds the contributions together.
The Daily Value for potassium used by the FDA for nutrition labeling is 4,700 mg per day for adults. This tool expresses results as a percentage of that value, but individual needs vary with age, kidney function, medications, and medical conditions. The low, moderate, and high categories are based on approximate per-drink thresholds of under 200 mg, 200 to 400 mg, and above 400 mg.
Reference: Potassium in Common Mixers
| Mixer | Approx. mg per 100 ml |
|---|---|
| Coconut water | 250 |
| Tomato juice | 229 |
| Orange juice | 200 |
| Grapefruit juice | 162 |
| Pineapple juice | 132 |
| Whole milk | 132 |
| Lemon juice | 103 |
| Lime juice | 102 |
| Cranberry juice cocktail | 77 |
| Cola, ginger ale, tonic, simple syrup | ~1 |
| Distilled spirits, soda water | ~0 |
Values are rounded averages. Freshly squeezed juice can vary with fruit variety and ripeness, and commercial products may have added potassium or be diluted with water.
Worked Example: Screwdriver vs. Bloody Mary
Screwdriver. A tall screwdriver made with 180 ml orange juice and 45 ml vodka contains about 360 mg of potassium, or 7.7% of the Daily Value. The vodka contributes almost nothing, and the orange juice dominates the total.
Bloody Mary. A standard Bloody Mary made with 120 ml tomato juice and 15 ml lemon juice supplies about 275 mg from tomato and 15 mg from lemon, for a total near 290 mg. Adding a lime wedge, extra tomato juice, or a larger glass can easily push the drink above 400 mg.
Tips for Lower-Potassium Cocktails
- Choose soda water, ginger ale, diet cola, or club soda as the base; these contribute essentially no potassium.
- Use small amounts of citrus as a garnish or squeeze rather than a full juice mixer.
- Dilute orange, tomato, or grapefruit juice with sparkling water to keep flavor while reducing potassium per serving.
- If you are tracking potassium closely, measure your pours instead of guessing — a heavy pour of juice can double the estimate.
Frequently Asked Questions
Do distilled spirits contain potassium?
No. Vodka, gin, rum, tequila, and whiskey are essentially potassium-free after distillation. The potassium in a mixed drink almost always comes from juice, dairy, coconut products, or other mixers.
Are packaged juices different from fresh juice?
Packaged juices can be similar, but labels matter. Some 'juice cocktails' are mostly water and added sugar and may contain less potassium ounce for ounce, while fortified juices could contain more. If you see potassium listed on the Nutrition Facts panel, use that number instead.
Why does potassium matter for kidney health?
People with chronic kidney disease or those taking certain blood pressure medications may need to limit potassium. This tool is an educational estimate, not medical advice. If you have a medical condition, review your intake with a doctor or renal dietitian.
Limitations and Accuracy Notes
The results are best treated as a planning estimate rather than a lab measurement. Actual potassium depends on the exact brand, batch, fruit maturity, portion size, and whether ice dilutes the drink. Values in this calculator reflect common averages and may differ from a specific product's label.
For more precise data, check the USDA FoodData Central database or the Nutrition Facts panel on packaged juices. For guidance on potassium in kidney-friendly diets, see the National Kidney Foundation. The FDA's daily value reference is described in its Daily Value guidance.
