The complex results indicated that the L-Theanine-caffeine combination might be a potential therapeutic option for ADHD-associated impairments in sustained attention, inhibitory control, and overall cognitive performance.8 The researchers suggested the morning administration of this combination of L-...

We examined the acute effects of l-theanine, caffeine and their combination on sustained attention, inhibitory control and overall cognition in boys with attention deficit hyperactivity disorder (ADHD). l-Theanine (2.5 mg/kg), caffeine (2.0 mg/kg), their combination and a placebo were ...
of L-theanine (50 mg) and caffeine (75 mg), alone and in combination; these doses were more reflective of those in 1 or 2 cups of tea. The authors observed significantly fewer errors with L-theanine compared with the combination (P<0.05) when testing for reaction time to congruent and...
l-Theanine and caffeine did not reduce the number of errors in a sustained attention task when comparing the combination therapy with either treatment alone [83]. Caffeine ingested at 150 mg orally improved fatigue perception, rapid visual information processing (RVIP), and reaction time. The ...
Research shows L-theanine can increase attention span and reaction time in people who are prone to anxiety. It may help improve accuracy—one study shows that taking L-theanine reduced the number of errors made in a test of attention. Sometimes, L-theanine is used with caffeine to enhance ...

L-theanine and caffeine are typically found together in tea. L-theanine often enhances the cognitive improvement effects of caffeine while reducing its negative effects (such as increased blood pressure) [24,25]. In 5 trials on 124 healthy people, this combination improved sustained and target-spe...
