Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Green tea (Camellia sinensis) has gained attention for its potential anxiolytic (anxiety-reducing) effects, supported by both traditional use and emerging scientific evidence. Traditionally, green tea has been consumed for its calming and health-promoting properties, particularly in East Asian cultures. Scientifically, the focus has been on two key components: L-theanine, an amino acid unique to tea, and moderate amounts of caffeine. L-theanine has been shown in several small-scale clinical studies and animal models to promote relaxation, reduce perceived stress, and improve focus without causing drowsiness. The mechanism is thought to involve modulation of neurotransmitters such as GABA, serotonin, and dopamine, as well as influencing alpha brain wave activity associated with a relaxed, alert mental state.

Systematic reviews and randomized controlled trials have found that L-theanine supplementation may reduce stress and anxiety in both healthy individuals and those with mild anxiety, though the effects are generally modest. Green tea as a beverage provides lower concentrations of L-theanine than those used in most studies, so its anxiolytic potential from regular consumption is less clear. Green tea’s low caffeine content compared to coffee may also make it a gentler option for those sensitive to stimulants. However, more robust, large-scale studies are needed to confirm its efficacy for clinical anxiety disorders. In summary, while green tea and its components have some scientific backing for supporting mild anxiety, evidence is preliminary and not sufficient to recommend it as a primary treatment for anxiety disorders.
