In this article, we will be exploring the link between green tea and caffeine, and comparing green tea with some other caffeinated drinks.

What Is Caffeine?

A compound naturally found in the leaves of many plants, caffeine is consumed around the world to fight fatigue and increase alertness. It works by blocking adenosine – a neurotransmitter that accumulates throughout the day and makes us feel tired.

Caffeine is found to have many health benefits, including improved exercise performance, reducing the risk of depression, and improved metabolism.

Caffeine In Green Tea

Compared to other teas and caffeinated drinks, green tea doesn’t have that much caffeine. However, the amount of caffeine in green tea largely depends on the plant that’s been used to make the tea. For example, older tea leaves usually have more caffeine.

One serving of green tea (8 oz.) has between 30 and 50 milligrams of caffeine. Compare that to instant coffee (27-173 mg), espresso (240–720 mg), or black tea (25–110 mg), and you’ll see why green tea is a safe alternative.

The Bottom Line

Current recommendations for caffeine intake are at 400 milligrams per day, while it’s not recommended to have more than 200 mg at one sitting. To get this amount of caffeine, you would have to drink more than four cups of green tea, so it’s safe to say that the link between green tea and caffeine is nothing to worry about.
