Synopsis

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

Green tea (Camellia sinensis) is often promoted for its potential to support cognitive function, including concentration. This use is supported by scientific evidence, primarily due to two active compounds: caffeine and L-theanine. Green tea contains moderate levels of caffeine, a well-known stimulant that can enhance alertness, attention, and concentration. Numerous studies have shown that caffeine improves various aspects of cognitive performance, including reaction time, vigilance, and attention span.

However, green tea is unique in that it also contains L-theanine, an amino acid not commonly found in other plants. L-theanine has calming properties and is believed to modulate the stimulating effects of caffeine, resulting in a state of relaxed alertness or focused calm. Several randomized controlled trials suggest that the combination of caffeine and L-theanine can improve attention and mental focus more effectively than caffeine alone, with reduced jitteriness and anxiety.

Systematic reviews and meta-analyses indicate that green tea extracts or its individual components may have small to moderate benefits for cognitive performance, especially in tasks requiring sustained attention. While most studies are short-term and often use higher doses of extracts than found in a typical cup of green tea, the evidence for improved concentration is stronger than for many other herbal remedies. Therefore, the use of green tea to support concentration is justified by scientific research, though the effect size is moderate and may vary between individuals.
