Does Green Tea Have Caffeine and If So, Should I Be Drinking It?

Green tea has between 10 to 80 milligrams of caffeine per cup.  More importantly, it contains catechins which are antioxidants that are good for your health, and help reduce the affects of aging. So, you probably shouldn’t worry too much about the caffeine, as long as you are careful about your overall daily consumption.

According to the experts at the Mayo Clinic, exceeding 500 milligrams of caffeine per day can cause health problems such as anxiety, nervousness, heart palpitations and insomnia. If most of your daily caffeine consumption is from tea or coffee, you are probably okay.

However, if you are taking any dietary supplements you should be aware most contain caffeine and combining them with tea or coffee consumption could be unhealthy.

In fact, many weight loss products contain large amounts of caffeine, in addition to other stimulants, such tea-extracts which often contain natural amounts of caffeine. Some of the most popular brands contain 500 milligrams per dose, which is right at the threshold of being dangerous.

Green tea supplements also contain caffeine, though the amount varies considerably. The intended purpose of the supplement will probably dictate the amount of caffeine present. Be sure to read the label, prior to buying the product.

Because green tea is good for the immune system, there are high quality immune system boosters on the market that contain 200 milligrams of the extract. On average the amount of caffeine in these extracts usually varies between 2% to 4%.  Something to consider when reviewing what the dosage is.

One of the main reasons the amount of caffeine in green tea varies, is the variation that occurs naturally in the actual plants, themselves. The caffeine content of each plant varies and even the amount of caffeine within leaves of the same plant can vary. The same is true of the nutritional content. So, the number of catechins in each leaf may vary, too.

Even decaffeinated green tea has caffeine in it – the amount has been reduced.  However the decaffeination process is not perfect and fails to remove 100% of the stimulant present in the plant. On top of that, the chemical solvents that are typically used in the decaffeinating process, often leaves behind a residue which is bad for your health. You’re actually better off drinking small amounts of the caffeinated varieties, rather than the decaffeinated varieties of green tea.

What about the caffeine content when the green tea extract is included in an anti-aging supplement? And why is the extract included in those supplements in the first place?

All natural extracts of green tea contain a small amount of caffeine. But, as mentioned above the quantity is rather minimal. As for why it is included in anti aging supplements at all, that’s due to its unique antioxidant activity.

As mentioned above, catechins are antioxidants, which help your body resist aging.  And, as antioxidants go, they are some of the better ones, although glutathione is far more potent. The best anti-aging supplements contain the reduced form of l-glutathione (because it is more easily absorbed by the body), a good amount of catechins and a number of other antioxidants.

In summary, if you want the benefit of green tea without the caffeine, then you’re better off taking a high quality supplement. They may help everyone live a little longer.
