The Effects of L-theanine on Objective Sleep Quality in Boys with ADHD

 

s3Over 100 boys (8-12 years) who had been diagnosed with ADHD were randomly assigned to a total of 400 mg daily L-theanine (Suntheanine® -2 tablets after school and 2 tablets at bedtime) or placebo for 6 weeks. The subjects were evaluated for 5 consecutive nights at the beginning and end of the study using wrist actigraphy. The L-theanine group had significantly higher sleep percentage and efficiency scores and a non-significant trend for less activity during sleep. Sleep latency and other sleep parameters were unchanged. The Pediatric Sleep Questionnaire (PSQ) completed by the parents suggested the parents were not particularly aware of their children’s sleep quality.
