Lipton Green Tea: Complete Caffeine Guide
A standard 240 ml cup of brewed Lipton green tea contains 28 mg of caffeine.
- One 240 ml cup = 28 mg caffeine (dataset / USDA baseline).
- Green tea has roughly one-third the caffeine of drip coffee (240 ml drip = 96 mg).
- After one population-average half-life (~5.7 h) about 14 mg remains from a 28 mg dose; after 12 h ~6 mg.
- FDA guidance: healthy adults should limit caffeine to 400 mg/day; pregnancy guidance is ~200 mg/day and the AAP discourages routine caffeine for adolescents.
Caffeine in standard Lipton green tea
When people ask "does Lipton green tea have caffeine?" the short factual answer is yes: brewed green tea listed in the dataset is 240 ml = 28 mg (11.7 mg/100 ml). This value matches the typical brewed green tea entry in FoodData Central and industry nutrient tables used as a reference point. Bottled or sweetened Lipton products can differ; if a product label or Lipton product page gives a specific number, use that for accuracy.
How Lipton green tea compares to other drinks
Put the 28 mg into context: green tea is low on the caffeine spectrum compared with coffee, matcha and many energy drinks. The table below uses dataset values so apples-to-apples comparisons are exact.
| Drink (serving) | Serving size | Caffeine (mg) |
|---|---|---|
| Lipton / standard green tea (brewed) | 240 ml | 28 mg |
| Black tea | 240 ml | 47 mg |
| Matcha (1 tsp) | 240 ml | 70 mg |
| Drip coffee | 240 ml | 96 mg |
| Espresso (single) | 30 ml | 63 mg |
| Red Bull (can) | 250 ml | 80 mg |
Varieties: diet and citrus Lipton green teas
Lipton sells a range of flavor variants (diet, citrus, bottled iced green tea). The dataset only supplies generic "green tea" values, so use the 28 mg brewed number as the baseline. Bottled iced teas and flavored ready-to-drink products often have similar or slightly lower caffeine per 100 ml than brewed tea because they’re diluted or use different extracts—check the nutrition label. If the label is missing, treat bottled green tea as an estimate and track it conservatively in apps like CoffeeLog.
What changes the caffeine number: brewing, bags vs. loose, and additions
Brewing time and temperature
Extraction rises with hotter water and longer steep times: steep 2–3 minutes yields a lower caffeine extraction than 5+ minutes. Green tea is usually steeped cooler and shorter than black tea, which keeps caffeine lower.
Bagged tea vs. loose leaf vs. matcha
Bagged and loose-leaf brewed green tea sit in the same range when steeped similarly. Matcha uses whole powdered leaves and delivers more caffeine—dataset shows 70 mg per 1 tsp prepared drink—because you ingest the leaf matter rather than an infusion.
How long caffeine from Lipton green tea affects you (decay math)
Use the population-average half-life of caffeine, 5.7 hours, as a practical rule: caffeine roughly halves every ~5.7 h. Below is a concrete decay table starting from the 28 mg dose in a 240 ml cup.
| Time after drinking | % remaining (approx) | Mg remaining (from 28 mg) |
|---|---|---|
| 0 h | 100% | 28 mg |
| 3 h | ≈69% | ≈19 mg |
| 5.7 h (one half-life) | ≈50% | ≈14 mg |
| 6 h | ≈48% | ≈13 mg |
| 9 h | ≈33% | ≈9 mg |
| 12 h | ≈23% | ≈6 mg |
Practical note: if you drink one cup with 28 mg late afternoon, measurable caffeine remains overnight for many people; sensitive sleepers should avoid additional caffeine within 6–8 hours of intended bedtime. Individual half-life varies with age, genetics, smoking status, pregnancy and some medications.
Health and safety context
Authoritative limits: the U.S. FDA cites about 400 mg/day as the safe upper limit for healthy adults; many authorities (and obstetric guidance) recommend keeping pregnancy caffeine near 200 mg/day. The American Academy of Pediatrics discourages routine caffeine for adolescents. A single 240 ml cup of Lipton green tea (28 mg) uses a small fraction of these limits, but cumulative intake from multiple drinks, chocolate and medications can add up.
Those with anxiety, arrhythmias, or caffeine sensitivity should treat even low-caffeine drinks cautiously and consult a clinician. For suspected overdose (very high intake, severe palpitations, vomiting, fainting) seek emergency care.
Tracking and practical tips
If you regularly drink Lipton green tea and other caffeine sources, tracking totals matters: 10 cups of green tea = 280 mg, approaching common daily thresholds. Use the Nutrition Facts label when available and log servings precisely; CoffeeLog can automate sums across drinks and show time-based decay so you know how much caffeine is likely still active before bedtime.
To reduce intake: shorten steep time, switch to decaf green tea (dataset decaf coffee is 3 mg per 240 ml as a reference but decaf tea varies), choose herbal caffeine-free blends or reduce frequency.

Frequently asked questions
Does Lipton green tea have caffeine?
Yes. A standard 240 ml cup of brewed green tea contains 28 mg of caffeine according to the dataset (the same baseline used by USDA FoodData Central).
Is Lipton green tea decaf?
Lipton offers decaffeinated varieties, but the dataset’s brewed green tea entry (240 ml) is 28 mg; decaf products should be checked on the label because decaf caffeine content varies by product.
How does Lipton green tea compare to coffee for caffeine?
Much lower: a 240 ml cup of drip coffee is 96 mg in the dataset, roughly 3½ times the 28 mg in green tea.
Will one cup of Lipton green tea affect my sleep?
Possibly—after 6 hours about 13 mg remains from a 28 mg cup and after 12 hours about 6 mg; sensitive sleepers should avoid caffeine within 6–8 hours of bedtime.
How much caffeine is safe per day?
For healthy adults the FDA cites about 400 mg/day as an upper limit; pregnancy guidance suggests keeping intake near 200 mg/day and the AAP discourages routine caffeine for adolescents.
Can I track Lipton green tea caffeine automatically?
Yes—use a tracker like CoffeeLog or log exact serving sizes and check product labels; tracking helps add up multiple low-caffeine drinks that can approach daily limits.
