If you are mindful about your caffeine consumption, you might want to think this through.

What is green tea

Green tea is a potentially healthy type of “true tea” that’s made up of the leaves of the tea plant called Camellia sinensis. Typically cultivated in China and Japan, green tea has gained global recognition when it comes to healthy beverages. Green is flooded with health benefits and is recommended by several health experts. There are different types of green tea, like matcha, dragon well green tea, gunpowder, and sencha. Different green teas have different flavors and benefits.

Green tea has had a reputation for being super-healthy which might have led to this common myth that green tea is naturally caffeine-free. However, that’s not true. Green tea does contain natural caffeine.

What is caffeine?

Caffeine is a natural chemical that’s typically found in the leaves, beans, and fruits of over 60 plants. Its serves as a natural stimulant for the nervous system. Typically, people incorporate it into their diets to boost alertness and fight any fatigue. Although if consumed in moderation, caffeine has a number of health benefits, overconsuption can lead to restlessness, headaches, acidity, insomnia, or an uneven heartbeat. A number of food items and beverages have caffeine content, such as coffee, tea, green tea, chocolates, sodas, and even certain gums and candies. Here is a list that clarifies and compares caffeine content in common beverages,

  • Green tea: 30–50 mg caffeine content per serving (8 ounces)
  • Instant coffee: 27–173 mg caffeine content per serving (8 ounces)
  • Plain, brewed coffee: 102–200 mg caffeine content per serving (8 ounces)
  • Espresso: 240–720 mg caffeine content per serving (8 ounces)
  • Black tea: 25–110 mg caffeine content per serving (8 ounces)
  • Yerba mate: 65–130 mg caffeine content per serving (8 ounces)
  • Soft drinks: 23–37 mg caffeine content per serving (8 ounces)
  • Energy drinks: 72–80 mg caffeine content per serving (8 ounces)

Clearly, green tea contains around half the quantity of caffeine as other beverages like coffee and black tea.

How much caffeine does green tea contain?

When it comes to caffeine content, one cup of pure green tea typically contains about 25 milligrams of caffeine per serving. (8-ounce serving) Because, it’s 1/4th of the caffeine content in a typical cup of coffee, it’s usually considered low on caffeine. However, there are different types of green tea and each one has different caffeine content. Here is a list of some popular green tea brands and their caffeine content.

  • Lipton Brisk Green Tea (12 oz.) – 6 milligrams of caffeine (4 mg per 8 oz.)
  • Arizona Green Teas (23.5 oz.) – 22 milligrams of caffeine (under 7.5 mg per 8 oz.)
  • Snapple Green Tea (16 oz.) – 15 milligrams of caffeine (7.5 mg per 8 oz.)
  • SoBe Green Tea (20 oz.) – 35 milligrams of caffeine (14 mg per 8 oz.)
  • Nestea Peach Green Tea (20 oz.) – 42 milligrams of caffeine (16.8 mg per 8 oz.)

  • Starbucks Green Tea Creme Frappuccino (Tall / 12 oz.) – 75 milligrams of caffeine (50 mg per 8 oz.)

Again, the amount of caffeine also varies with the serving size, proportion of water and tea, brewing time and so much more.

  • Cutting back on coffee house green teas: If you like to go for green tea drinks at Starbucks or other coffee shops, you must know although they might be healthier than other drinks, they have a higher caffeine content than regular green tea.

  • Pick whole-leaf green teaAlthough green tea bags are far more convenient, they have more caffeine than loose green tea. Pick whole-leaf green tea to reduce your daily caffeine intake.
  • Go for late harvest teas: Typically, the caffeine content is higher in spring harvest teas (like Shincha) than late-harvest teas (like Bancha).
  • Pick twig teas: Twig teas are green teas made up of twigs and stems of the tea plant. These teas are typically low in caffeine, they include, teas like kukicha and houjicha.
  • Avoid shade-grown teas: Matcha and gyokuro are shade-grown teas that are naturally very high in caffeine. You must go for teas that are not shade-grown.
