Lipton Green Tea: Caffeine Content Explained
A brewed 240 ml cup of Lipton Green Tea contains 28 mg of caffeine.
- One 240 ml brewed cup ≈ 28 mg caffeine (USDA FoodData Central baseline).
- Bottled/iced green tea (355 ml) typically ≈ 45 mg.
- Compared with drip coffee (240 ml ≈ 96 mg), Lipton green tea has ~30% of the caffeine.
- After 6 hours roughly 13 mg remains from a 28 mg dose (population half-life ≈5.7 h).
Average caffeine in Lipton green tea
The standard dataset value for green tea — which applies to common brewed bagged green tea like Lipton — is 28 mg per 240 ml cup (about 11.7 mg/100 ml). That number comes from nutrient databases such as USDA FoodData Central and matches what companies and lab analyses report for a typical cup brewed to package instructions.
Caffeine levels in different Lipton varieties
Not every Lipton product has the same caffeine because format and serving size change total milligrams.
Loose/bagged brewed green tea (standard cup)
Brewed from a tea bag into 240 ml, use the dataset value: 28 mg per cup. Strength rises with longer steep time and larger cup volume.
Bottled/iced Lipton Green Tea
Bottled iced tea in the dataset is 45 mg per 355 ml bottle. When buying Lipton bottled green tea or citrus-flavored bottled green tea, expect numbers close to that 45 mg per 355 ml sample unless the label states otherwise.
Comparing Lipton green tea to other drinks
Put the numbers side-by-side to see how Lipton green tea stacks up.
| Drink (serving) | Serving size | Caffeine (mg) |
|---|---|---|
| Lipton brewed green tea | 240 ml | 28 mg |
| Bottled iced tea (typical) | 355 ml | 45 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 |
Use this comparison when swapping beverages: a single brewed cup of Lipton green tea supplies much less caffeine than coffee and substantially less than matcha, but more than herbal tea (0 mg) or decaf coffee (3 mg per 240 ml).
How caffeine decays in your body (what remains over time)
Caffeine follows roughly exponential decay with an average half-life of about 5.7 hours (population average). That means the milligrams in your bloodstream reduce to roughly the percentages listed below; apply those percentages to the 28 mg Lipton dose to see remaining caffeine.
| Time after drinking | % remaining (approx.) | Remaining from 28 mg | Remaining from 45 mg (bottled) |
|---|---|---|---|
| 3 hours | ~69% | ~19 mg | ~31 mg |
| 6 hours | ~48% | ~13 mg | ~22 mg |
| 9 hours | ~33% | ~9 mg | ~15 mg |
| 12 hours | ~23% | ~6 mg | ~10 mg |
Example: drinking a 240 ml cup at 8:00 AM leaves roughly 13 mg of caffeine in your system by 2:00 PM and about 6 mg by 8:00 PM (averages; individual metabolism varies).
Factors that change caffeine in your Lipton cup
Quantity and steep variables change the total milligrams more than small cultivar differences:
- Steep time and water temperature: longer steep and hotter water extract more caffeine; doubling steep time can noticeably increase mg.
- Serving size: a larger mug scales mg linearly — 480 ml would be ~56 mg if brewed to the same strength.
- Bag vs loose leaf and blend: fannings/teabags often extract faster than whole-leaf; flavored blends may use less leaf per bag.
- Bottled vs brewed: bottled iced tea frequently uses concentrated extracts and sweeteners and is measured per bottle (e.g., 45 mg/355 ml in the dataset).
Health context and safety limits
For healthy adults, the FDA cites about 400 mg/day as a generally safe upper limit; one Lipton brewed cup at 28 mg is a small fraction of that. During pregnancy many organizations recommend limiting to roughly 200 mg/day; for adolescents the American Academy of Pediatrics discourages routine caffeine use. If you have heart conditions, anxiety, or are sensitive to stimulants, consult a clinician.
Timing vs sleep and practical tips
Because ~48% of caffeine remains after 6 hours on average, having Lipton green tea late in the afternoon can still contribute low-level stimulation at bedtime for sensitive people. For better sleep, try stopping caffeine 6–8 hours before planned sleep or switch to decaf/herbal alternatives.
How to track your intake
Track servings and exact mg using a log. CoffeeLog can automate tracking for beverages and compute daily totals and decay estimates so you know how close you are to 200 mg (pregnancy) or 400 mg (general adult) limits and how much caffeine remains at bedtime.

Frequently asked questions
How much caffeine is in a cup of Lipton green tea?
A typical brewed 240 ml cup of Lipton green tea contains about 28 mg of caffeine (USDA FoodData Central baseline). Strength rises with longer steep times or larger servings.
Is Lipton bottled green tea higher in caffeine than brewed?
Yes—bottled iced tea in the dataset is roughly 45 mg per 355 ml. Bottled formulations and serving sizes often deliver more total mg than a standard brewed 240 ml cup.
How long does caffeine from Lipton green tea stay in my system?
Using the average half-life of 5.7 hours, about 48% remains after 6 hours. From a 28 mg cup, expect ~13 mg after 6 hours and ~6 mg after 12 hours (population average).
Can I drink Lipton green tea during pregnancy?
Many guidelines suggest limiting caffeine to about 200 mg/day during pregnancy. A 28 mg cup is low, but cumulative intake from other sources matters—check total daily mg with your clinician.
How does Lipton green tea compare to coffee?
A 240 ml brewed cup of Lipton green tea (28 mg) has roughly 30% of the caffeine of 240 ml drip coffee (96 mg). Coffee and espresso contain substantially more mg per serving.
What's the best way to track my caffeine from Lipton drinks?
Log exact drink type and serving size and total daily mg. Apps like CoffeeLog can automate entries, sum totals, and estimate remaining caffeine over time.
