How much caffeine is in Sunkist Orange?

A 355 ml can of Sunkist Orange contains 41 mg of caffeine. This figure comes from the TrackCaffeine dataset (TrackCaffeine dataset, 2026-08-02) and the same dataset records the beverage at 11.5 mg per 100 ml.

Caffeine is a central nervous system stimulant that raises alertness over the hours after ingestion; that definition is given here to set expectations for what 41 mg does physiologically. The 41 mg amount is about 0.4 times a standard 240 ml cup of drip coffee, where drip coffee contains 96 mg per 240 ml according to our reference points (TrackCaffeine dataset, 2026-08-02).

For most adults, 41 mg produces a mild stimulatory effect that often appears within 15–60 minutes and can alter subjective alertness for several hours after drinking, with the magnitude and timing depending on body size, habitual use, and sensitivity (TrackCaffeine dataset, 2026-08-02).

How long Sunkist Orange stays in your system

Half-life is the time it takes for the measurable amount of a substance in the body to fall to half its current value; that definition is provided here so the decay arithmetic below is clear. TrackCaffeine models caffeine elimination as first-order kinetics with a population-average half-life of 5.7 hours (TrackCaffeine model, 2026-08-02), so remaining = dose × 0.5^(hours / 5.7).

Applying the formula to this 41 mg dose gives the following arithmetic and rounded results using the 5.7-hour half-life (TrackCaffeine model, 2026-08-02): 3 hours: 41 × 0.5^(3/5.7) = 41 × 0.6946 ≈ 28.5 mg (reported as ≈28 mg); 6 hours: 41 × 0.5^(6/5.7) = 41 × 0.4820 ≈ 19.8 mg (≈20 mg); 9 hours: 41 × 0.5^(9/5.7) = 41 × 0.3349 ≈ 13.7 mg (≈14 mg); 12 hours: 41 × 0.5^(12/5.7) = 41 × 0.2326 ≈ 9.5 mg (≈10 mg). Each numeric remaining value above is computed from the TrackCaffeine model (TrackCaffeine model, 2026-08-02).

As an example, if the can is consumed at 15:00, the model predicts roughly 28 mg remaining at 18:00, about 20 mg at 21:00, about 14 mg at 00:00, and about 10 mg at 03:00 (TrackCaffeine model, 2026-08-02). Those residual amounts are measurable on the first-order model but translate variably into subjective effects depending on individual sensitivity and accumulated caffeine from other sources (TrackCaffeine dataset, 2026-08-02).

The U.S. Food and Drug Administration recommends 400 mg per day as a guidance for healthy adults; that 400 mg/day figure is cited by the FDA (U.S. Food and Drug Administration, 2018) and provides a benchmark for how many Sunkist cans fit into the day: 41 mg is 10% of 400 mg, so roughly 9.75 cans would equal the 400 mg guidance by simple division (41 mg per can; math and guidance from the FDA, U.S. Food and Drug Administration, 2018).

For bedtime planning, caffeine consumed earlier in the evening can remain at measurable levels overnight: the TrackCaffeine model with a 5.7-hour half-life predicts about 20 mg remaining six hours after a 41 mg dose (TrackCaffeine model, 2026-08-02), and controlled sleep research shows that 400 mg taken six hours before bedtime decreases total sleep time by over an hour (Drake et al., Journal of Clinical Sleep Medicine, 2013). Use our calculator to model different timings (latest cup before bedtime) and to find limits scaled to weight (safe daily limit by body weight), both of which reference the dataset and model (TrackCaffeine dataset, 2026-08-02; TrackCaffeine model, 2026-08-02).

Certain groups should be more cautious: EFSA recommends a 200 mg per day guidance in pregnancy (EFSA Scientific Opinion, 2015), and adolescents and documented caffeine-sensitive individuals commonly experience strong effects from substantially lower doses than adults (EFSA Scientific Opinion, 2015; TrackCaffeine dataset, 2026-08-02). These specific guidance values are named here so readers can match personal circumstances to authoritative recommendations (EFSA Scientific Opinion, 2015).

Within the soda category this Sunkist Orange can (41 mg per 355 ml, TrackCaffeine dataset, 2026-08-02) sits above Coca-Cola (355 ml) at 34 mg and below Mountain Dew (355 ml) at 54 mg, with Pepsi (355 ml) at 38 mg and Dr Pepper (355 ml) at 42 mg in the same dataset (TrackCaffeine dataset, 2026-08-02). That places Sunkist near the middle of common caffeinated sodas by milligram content in our collection of measurements (TrackCaffeine dataset, 2026-08-02).

Compared to coffee, the difference is substantial on a per-serving basis: a standard 240 ml drip coffee contains 96 mg of caffeine in our reference points, so one Sunkist can is about 0.4 times that amount (TrackCaffeine dataset, 2026-08-02). If someone replaces a single 240 ml cup of drip coffee with a 355 ml Sunkist can, they reduce their caffeine intake by roughly 55 mg per exchange based on these reference values (TrackCaffeine dataset, 2026-08-02).

What changes the number for Sunkist Orange

Package size and product variant are the main levers that change the caffeine number for a soda; the TrackCaffeine dataset lists this Sunkist Orange can at 41 mg per 355 ml (TrackCaffeine dataset, 2026-08-02), while other sodas in our dataset range from 22 mg to 66 mg per similar serving sizes (TrackCaffeine dataset, 2026-08-02).

Formulation differences can push numbers up or down: for instance, Club-Mate (330 ml) is 66 mg per serving and Barq's Root Beer (355 ml) is 22 mg per serving in our dataset, illustrating the spread among carbonated drinks (TrackCaffeine dataset, 2026-08-02). Diet or zero-sugar variants sometimes differ because manufacturers use different caffeine-containing extracts or formulation processes; for example, the dataset lists Coca-Cola Diet Coke (355 ml) at 46 mg versus Coca-Cola Coke Zero (355 ml) at 34 mg (TrackCaffeine dataset, 2026-08-02).

Concrete factors that drive variation and why a single published figure is an estimate:

• Serving size: a 500 ml bottle multiplies the dose proportionally (dose scales with volume; TrackCaffeine dataset, 2026-08-02).
• Product variant and recipe: diet, zero, or energy formulations may add different caffeine sources (TrackCaffeine dataset, 2026-08-02).
• Batch and manufacturing variation: caffeine is added or derived from flavors and can vary by ± a few milligrams across lots (industry variability reported in public food composition sources, TrackCaffeine dataset, 2026-08-02).
• Decaffeinated options: when available, 'decaf' sodas are formulated with lower or negligible added caffeine and should be checked on the label (TrackCaffeine dataset, 2026-08-02).

Where this figure comes from

The 41 mg value on this page is the measurement reported for Sunkist Orange 355 ml in the TrackCaffeine dataset, which we reference directly (TrackCaffeine dataset, 2026-08-02). The dataset aggregates published product labels, manufacturer disclosures, and standard food composition sources to produce a single canonical figure for display (TrackCaffeine dataset, 2026-08-02).

Published values disagree for reasons described above: manufacturers may change formulations, labels can round numbers, and public food composition tables sometimes use averaged or laboratory-derived data; we will update this page when manufacturers publish new label information or when a laboratory analysis contradicts the listed figure (TrackCaffeine dataset, 2026-08-02).

Bottom line

Bottom line: a 355 ml can of Sunkist Orange contains 41 mg of caffeine (11.5 mg per 100 ml) as recorded in the TrackCaffeine dataset (TrackCaffeine dataset, 2026-08-02); that is about 0.4× a 240 ml cup of drip coffee at 96 mg per cup (TrackCaffeine dataset, 2026-08-02) and equals roughly 10% of the FDA 400 mg/day guidance (U.S. Food and Drug Administration, 2018).

On our first-order elimination model with a 5.7-hour half-life, the 41 mg dose is approximately 28 mg at 3 hours, 20 mg at 6 hours, 14 mg at 9 hours, and 10 mg at 12 hours after drinking (TrackCaffeine model, 2026-08-02).
