All Camellia sinensis plants contain caffeine – except one. For example, Camellia sinensis var sinensis is generally considered lower in caffeine than Camelia sinensis var assamica – but that doesn’t always need to be the case. Some will contain more caffeine from the others. However, there are different varieties of Camellia sinensis and many cultivars too. Tea plantĪll real tea is made from the same plant – Camellia sinensis.
However, not all of it will be extracted.Ĭaffeine content in tea will depend on many factors: 1. If you are using 5 grams of leaves, they may contain up to 174 mg of caffeine. One study concluded that tea made from Camellia sinensis tea plant may have around 14.3 to 34.8 milligrams of caffeine per gram of leaf. In fact, some green and white teas may contain more caffeine than black teas. It’s a common misconception that a cup of black tea will always contain the most caffeine, while the cup of white tea will be very gentle and almost caffeine-free. It’s almost impossible to say how much caffeine will your cup of tea contain. What will influence caffeine content in tea? High-caffeine, high-L-theanine tea may be a great option if you want a strong sustained energy boost. Studies showed that together, they may reduce headaches, fatigue and increase alertness and faster reactions than caffeine alone. Ĭombined, caffeine and L-theanine may help improve performance, including speed and focus. Studies showed that high mountain teas may contain more L-theanine than low grown teas. Both green, black, oolong and white teas may contain high and low levels of this amino acid. Some pu’erhs like raw pu’erh will have more L-theanine than ripe pu’erh, which may not have L-theanine at all. L-theanine is present in all types of tea except pu’erh. Tea contains L-theanine, one of amino acids that contribute to the feeling of calmness. In fact, drinking tea may even help you feel more rested the following day. It will give a more sustained energy throughout the day. Unlike coffee, caffeine in tea won’t give you the jitters. Tea may offer other health benefits too, such as antioxidant activity, promoting weight loss, anti inflammatory activity and others. There are thousands of different flavors to enjoy, and you are likely to find the one you enjoy the most. Next, tea doesn’t need to be bitter, especially if you brew it correctly. Tea generally contains less caffeine than coffee, which makes it more difficult to “overdose” on caffeine.
Firstly, tea is unlikely to give you the jitters. There are several reasons you may want to drink tea instead of a cup of coffee.
