Consuming too much caffeine may cause side effects like:. Talk to a healthcare provider if you are pregnant or breastfeeding. They may advise drinking less than milligrams of caffeine. Too much green tea may raise the risk of birth defects, and caffeine may pass through breast milk.
High doses of green tea may interact with certain medications, including those that treat heart problems and high blood pressure. Although rare, research has linked liver problems to tea products, especially green tea extract.
Whether you sip your green tea iced or hot, here are a few tips to keep in mind:. The caffeine in green tea is a stimulant, increasing alertness and keeping you awake.
You may drink a cup of green tea in the morning as a substitute for coffee for an energy boost. In contrast, caffeine generally stays in your body for up to six hours, so avoid green tea too close to bedtime.
Consider pairing a cup of green tea with food. Caffeine increases the amount of acid in your stomach, which may cause an upset stomach and heartburn. There are several types of green tea, including:. One of the most common types of green tea is Sencha, typically made in Japan.
Sencha includes Bancha and Matcha. Bencha has less caffeine and L-theanine, while Matcha has the highest amounts.
Green tea is a staple in many cultures and may offer essential benefits, like protecting your bone, brain, and heart health. Even so, green tea may be risky for people with caffeine sensitivity or who take certain medications.
Ask a healthcare provider or dietitian for guidance about how green tea may impact your health goals if you do not currently drink it and are unsure if it's right for you.
You may be able to reap the possible benefits of green tea by consuming it daily. Other factors like eating a balanced diet, getting enough sleep , managing stress, and regularly exercising are essential to good health. Ensure that you are practicing healthy lifestyle changes in addition to drinking green tea daily.
It's safe to drink eight cups of green tea daily. Each eight-ounce cup of green tea has about 30—50 milligrams of caffeine. The Food and Drug Administration advises not drinking more than milligrams of caffeine daily.
Green tea products may add caffeine during manufacturing and only list the amount added. There's not enough evidence about the optimal amount of green tea to reap the most benefits.
Manufacturing typically destroys antioxidants. As a result, bottled green tea drinks, decaf green tea, and green tea powders may lack antioxidants. Instead, try limiting the amount of added sugars, like honey and stevia, and steeping your green tea at home to get the most benefits.

Green tea is primarily made and consumed in China, Japan, and countries in North Africa and the Middle East. Unlike black and oolong tea leaves, green tea leaves do not undergo a fermenting process. As a result, green tea has higher levels of antioxidant compounds. In a recent study, researchers randomly assigned 12 healthy people to receive a milk drink containing The effects of green tea on working memory and the connectivity between the frontal lobe, which plays an important part in retaining memories, and the parietal lobe, which plays an important role in processing the senses such as touch and taste, were evaluated. The researchers found that green tea extract increased working memory and the connectivity between the frontal and parietal lobes of the brain. This increase in connectivity was related to an improvement in the performance of tasks. The authors concluded that the benefits of green tea extract on mental function and memory may play an important role in potential treatment options for people with mental disorders or memory loss. Further research is warranted. |
