  • Additional notes

    "Only one randomized, double-blind, placebo-controlled trial to evaluate the effect of 200 mg of L-theanine twice a day for six weeks on sleep quality of 98 children (aged 8–12 years), with a diagnosis of attention-deficit/hyperactivity disorder (ADHD), has been published [36]. In the group taking L-theanine, actigraphic sleep and sleep efficiency scores improved with respect to the placebo group. No adverse events were reported, suggesting that a daily dosage of 400 mg of L-theanine can safely and effectively improve sleep quality in children with ADHD. Lyon, M.R.; Kapoor, M.P.; Juneja, L.R.

    "ONLY give in the MORNING Bruni et al. [31] in 2004 were among the first to carry out an open pharmacological trial to verify the efficacy of L-5-hydroxyTRP (L-5-HTP) in 45 children (aged 3.2–10.6 years) with sleep terrors divided in two groups, one taking 2 mg/kg per day of L-5-HTP at bedtime for 20 consecutive days and the control group in the watchful waiting without any treatment. Patients taking L-5-HTP decreased the number of episodes in 93.5% (29 out of 31) vs. 28.6% of the control group; the improvement was maintained after 6 months follow-up. Similarly, in a retrospective analysis of medical records, children aged 3 to 18 years with primary parasomnia that received L-TRP (daily dose range: 500–4500 mg, mean dose 2400 mg) experienced improvements in their parasomnia symptoms in 84% of cases, compared to only 47% of the non-treated group [35]. van Zyl, L.T.; Chung, S.A.; Shahid, A.; Shapiro, C.M.
