Stay Alert Without Getting the Jitters!

Does green tea contain caffeine? Well the answer might not be what you would expect.

All real tea comes from the same botanical, Camellia sinensis. Legend has it that the Emperor Shea Nung “discovered” it in 2737 BC in China, by accident when some wild tea leaves ended up in the water he was boiling. Around AD 800 Buddhist monks took the drink to Japan, where the tea drinking ceremony (the cha-no-yo) evolved. By the 16th century it was heading West with explorers who had visited Asia.

This infusion does have a mild stimulating effect. It naturally contains antioxidants, and the level of antioxidants found in it is a result of being unoxidixed. So now we’re on our way to answering the question, does green tea contain caffeine? “Oxidation” is just a way to describe how black, and other varieties are processed. Exposure to air is what causes the changes to occur in the leaf, making it look and taste different, as well as increasing the stimulating effects of those other varieties. The more oxidized, the more stimulant and the less antioxidant contained within.

The greatest benefits are due to a group of flavenoids called polyphenols, due to its lack of processing, it remains unaltered whilst the drying process concentrates these antioxidants. Polyphenols are potent antioxidants and have been shown to protect against heart disease, as they can prevent the oxidation of LDL, so called “bad” cholesterol.

Does green tea contain caffeine? The stimulant level of any given cup you drink varies based on how long you allow you it to brew, how hot the water is and whether it’s the second (or subsequent) brewing of the same batch of leaves. You can dispose of the majority of stimulant in your cup simply by steeping briefly in a cup of hot water, discard that cup, and then steep again in a second fresh cup of water. There are also variations of concentration based on how the product is produced. The active ingredients vary considerably depending upon where it was grown. Young leaves and buds are the usual parts used.

Does green tea contain caffeine? The content varies based on its type and preparation. Sources quote anywhere from 3 to 30 mg in a cup of green tea. This is half of what the black variety contains and about a quarter the content of your average cup of coffee. Regular tea contains between 30 and 60 mg. A can of Coke contains 34 mg. Instant coffee contains between 65 and 100 mg. Drip filtered coffee can contain up to 200 mg. The stimulant affects you differently than that in coffee. Coffee gives you a very fast lift, but an equally sharp decline in your energy is felt later.

Does green tea contain caffeine? It gives you a slower, more delayed lift, which leads to a plateau, and then a secondary lift. It does not give you a sharp decline, rather it very gradually decreases so you don’t feel the negative effects of the decrease in the way it is felt with coffee. However, teabags can release up to twice as much as loose leaves because they are made with low grade leaves that are powdered and crushed up. As soon as a leaf is crushed, the surface area of the leaf is exposed to more air, which causes it to lose nutrient value, go stale and lose flavor rapidly.

Does green tea contain caffeine? It should be remembered to never brew or drink it with boiling water. The high temperature can destroy valuable therapeutic antioxidant compounds. L-theanine is a free (non-protein) amino acid constituting between 1 and 2-percent of the dry weight of tea leaves. This amino acid actually acts antagonistically against the stimulatory effects of caffeine on the nervous system. The length of time you steep it will directly affect the amount of the concentration as well. All in all, the benefits of drinking it far out way the risks.
