Caffeine and green tea


It turns out that caffeine can have a lot of positive health benefits and, despite what you may have heard, relatively few drawbacks. Even though tea contains caffeine, not only does the caffeine stimulate the brain and central nervous system, but it appears to protect it as well. Caffeine doesn’t make you any smarter but it can make you more alert and boost your ability to concentrate. Of course moderation is key and always listen to your body – if you’re getting tremors or other signs of excess caffeine you need to cut back.

Anecdotally – and applying good old common-sense – 1-2 cups a day seems like a good balance.
Also keep in mind that green tea on avg contains 3-25mgs of caffeine whereas coffee contains 50-180mgs.

All teas contain some caffeine (green, white and black tea all come from the same bush – Camellia Sinensis). As you can see from the following table, green and white teas are the best option if you are looking for a low caffeine option. Caffeine levels can vary according to the seasonal conditions and processing methods.

Approximate caffeine levels

Beverage Caffeine per oz
Caffeine per cup
Espresso Coffee 51mg 180mg
Black Tea 6mg 47mg
Green Tea 3mg 25mg
White Tea 2mg 15mg


Some people are also saying that genetics also plays a part in your tolerance to caffeine, but this isn’t widely reported.

How to lessen the caffeine in your tea

If you steep the tea for about 20-30 seconds then tip the water out, you’ll get getting rid of about 20% of the caffeine in the tea. The longer you steep it for the more caffeine will be extracted.
