Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Green tea (Camellia sinensis) is commonly used as a natural remedy to support alertness and reduce fatigue. Its primary bioactive compounds relevant to this effect include caffeine and L-theanine. Caffeine is a well-established central nervous system stimulant that can temporarily reduce the perception of fatigue and improve alertness. Multiple clinical studies have shown that moderate caffeine intake (such as that found in green tea, which typically contains 20–45 mg per cup) can help counteract feelings of tiredness and improve cognitive and physical performance in the short term. Additionally, L-theanine, an amino acid unique to tea, has been shown to promote relaxation without sedation, and when combined with caffeine, may help to improve attention and focus with fewer unwanted side effects (such as jitters) compared to caffeine alone.

While green tea is less potent than coffee in terms of caffeine content, its combination of stimulatory and calming compounds appears to make it a popular choice for those seeking gentle fatigue relief. Reviews of human studies suggest that green tea consumption is associated with improvements in self-reported fatigue and enhanced mental alertness, particularly in populations experiencing mild fatigue or needing to maintain wakefulness. However, the effects are generally modest, and green tea is not considered a substitute for addressing underlying causes of chronic fatigue. In summary, there is moderate scientific support for the use of green tea to help alleviate temporary fatigue, primarily due to its caffeine and L-theanine content.
