No safety concerns have been reported for green tea consumed as a beverage by adults. However, green tea does contain caffeine. Side effects of green tea extract supplements include nausea, constipation, abdominal discomfort, and increased blood pressure. Although uncommon, liver injury has been reported in some people who used green tea products, primarily green tea extracts in tablet or capsule form. Individuals with a specific variant of a gene that plays an important role in immune function appear to be especially susceptible. Between 5 and 15 percent of Americans have this variant. Green tea at high doses has been shown to reduce blood levels and, therefore, the effectiveness of the drug nadolol, a beta-blocker used for high blood pressure and heart problems. Green tea extract can reduce blood levels of the cholesterol-lowering drug atorvastatin. A study funded by the National Center for Complementary and Integrative Health showed an interaction between green tea and the drug raloxifene, which is used to treat osteoporosis. Green tea may also interact with other medicines. If you take any type of medicine, talk with your health care provider before using green tea supplements or other herbal products; some herbs and medicines interact in harmful ways. During pregnancy, caffeine intake should not exceed moderate levels. Green tea is a source of caffeine. If you are or might be pregnant, consult your health care provider for advice about caffeine intake. Caffeine can pass to your infant through breast milk; if you consume high levels of caffeine, it can lead to symptoms such as fussiness and poor sleep patterns in your infant. However, breastfeeding infants usually do not have adverse effects when mothers consume low-to-moderate levels of caffeine.
