Does Green Tea Have Caffeine?
If you’re looking for an alternative to coffee, consider switching to green tea. Green tea is made from the camellia sinensis plant and is one of the least processed forms of tea available.

But does green tea have caffeine? Will it do the trick to start your day off the way coffee does?
Green tea does contain caffeine. Even when a tea is marked as decaffeinated, it still contains small amounts. Green tea is made by steaming, pan frying and drying the leaves, which provides a milder, grassy flavor compared to black or oolong teas which are made by withering and oxidizing the leaves.
The amount of caffeine in any tea is dependent upon several factors including the climate conditions where the plant is grown, harvest times, drying methods and preparation of the actual tea (hot versus cold brewed).
Green tea does have caffeine, but it also has a variety of health benefits. It contains polyphenols which are antioxidants and green tea may enhance cognitive function due to its content of the amino acid L-theanine. It's worth noting that green tea contains this amino acid, which works synergistically with caffeine to improve alertness and concentration more effectively than caffeine alone. L-theanine has also been shown to have various other benefits, including promoting relaxation and reducing stress. Some studies have shown that green tea can positively enhance metabolism when combined with exercise. And there is some evidence that drinking green tea may lower your risk of cancer, though more research is needed in this area.
If you’re looking for green tea with caffeine, keep an eye out for matcha too. You might be wondering, what is matcha? It’s a powdered form of green tea. Matcha is commonly available in stores and at coffee counters and it can be used in a variety of recipes to deliver the green tea caffeine jolt you want.

Or two to three cups of black coffee, ideally spaced out over a few hours. As green tea does have less caffeine than coffee or energy drinks, you can consume more and stay under the recommended limit. So if you like to sip throughout the day, green tea is a great alternative to coffee or energy drinks.
Green tea is not only lower in caffeine than many other popular beverages, but it’s also healthy and tasty.
