Apple Cider Vinegar Water Calories and Nutrition

DetoxWater Editorial Team•Published November 2, 2026

A 250 ml (about 1 cup) glass of apple cider vinegar water has approximately 1–3 kcal when made with 1–3 teaspoons (5–15 ml) of unsweetened apple cider vinegar and plain water. The amount of vinegar, the product and any added sweeteners or juice can change the total. Use the ai nutrition analyzer to estimate calories for your own ingredients and quantities.

These estimates apply to a simple mixture, not every recipe for apple cider vinegar water. Check the label if you use a flavored or sweetened product.

How many calories are in apple cider vinegar water?

Plain water contributes no calories, so the calories in a simple glass come from the apple cider vinegar. USDA FoodData Central lists cider vinegar at 21 kcal per 100 g. A glass uses only a small fraction of that amount.

Apple cider vinegar in a 250 ml glassEstimated calories
1 teaspoon (5 ml)About 1 kcal
2 teaspoons (10 ml)About 2 kcal
1 tablespoon (15 ml)About 3 kcal

These estimates treat 1 ml of apple cider vinegar as approximately 1 g and assume the rest of the glass is plain water. They are rounded, so they are useful for planning rather than precise measurements. The calorie content of a particular product can differ from the USDA entry.

Sugar, honey, juice and other additions increase the total according to how much you use. Add their calories to those of the apple cider vinegar; diluting the mixture with more water does not remove calories already present. A larger final glass is not necessarily higher in calories if it contains the same ingredients in the same amounts.

If you add fruit pieces for flavor and leave them uneaten, do not count the whole fruit’s calories as calories in the water. Squeezing fruit into the drink or eating the pieces adds more calories than simply steeping them.

Apple cider vinegar is acidic, so dilute it rather than drinking it straight; frequent exposure to acidic drinks can erode tooth enamel. If it worsens reflux symptoms or you have difficulty swallowing, ask a clinician for advice.

What are the nutrition facts per 250 ml?

The table estimates a 250 ml glass made with 1 tablespoon (15 ml) of apple cider vinegar and about 235 ml of plain water, with nothing else added. It uses the USDA FoodData Central entry “Vinegar, cider” and excludes any minerals in the drinking water.

NutrientEstimated amount per 250 ml glass

Sugars0.06 g
Protein0 g
Fat0 g
Fiber0 g
Sodium0.75 mg
Potassium11 mg
Calcium1.1 mg
Magnesium0.75 mg
Vitamin C0 mg

For the calculation, 15 ml of apple cider vinegar is treated as approximately 15 g. Multiplying the USDA value of 21 kcal per 100 g by 15/100 gives 3.15 kcal, rounded to 3 kcal. The nutrient amounts are scaled in the same way.

These are estimates for the diluted drink, not for 250 ml of vinegar. Adding more water makes the drink less concentrated, but the total calories and nutrients remain roughly the same if the amount of apple cider vinegar stays the same.

The small quantities in this mixture do not make it a meaningful source of fiber or vitamin C. Its main contribution is fluid; the nutrient table should not be read as evidence of a special detox effect. The liver and kidneys do most of the body’s detoxification, while the lungs and gut also help eliminate waste.

How does it compare with juice and soda?

Unsweetened apple cider vinegar water generally has fewer calories than the same volume of fruit juice or regular sugar-sweetened soda. The comparison changes if you add juice or a caloric sweetener to the vinegar water.

DrinkMain calorie sourceComparison with plain apple cider vinegar water
Apple cider vinegar waterA small amount from the vinegarLow in calories without additions
Fruit juiceNaturally occurring sugarsGenerally higher in calories
Regular sodaAdded sugarsGenerally higher in calories
Diet sodaDepends on the productMay be similarly low in calories; check the label

Unsweetened fruit juice is not calorie-free: its naturally occurring sugars contribute calories even when no sugar has been added. Regular soda gets calories from added sugar, while products sold as diet or sugar-free can differ by brand.

For a useful comparison, check the serving size and calories on each label, then compare equal volumes. If you mix apple cider vinegar with juice instead of plain water, include the juice’s calories in the total rather than using the plain-water estimate.

Frequently asked questions

Does hot water change the calorie count?

Changing the water temperature does not meaningfully change the calories if the ingredient amounts stay the same.

Does apple cider vinegar water count as calorie-free during a fast?

A mixture containing apple cider vinegar has a small amount of calories, so it is not strictly calorie-free. Fasting rules vary by purpose.

Does apple cider vinegar with the mother have the same calories?

The amount can vary by product. Check the label rather than assuming it matches the USDA estimate for cider vinegar.
