Fantastic news for parents of ADHD children: the amino acid L-theanine will help their children sleep. A recent Canadian study proved that L-theanine significantly improves sleep quality in ADHD children, which benefits the entire family.
ADHD (attention deficit hyperactivity disorder) is a neurobehavioral disorder characterized by either significant difficulties of inattention or hyperactivity and impulsiveness or a combination of the two.
As many as 50% of ADHD children experience sleep problems. ADHD children often resist going to bed, and take a long time to fall asleep. They wake at night, and may also suffer from restless legs syndrome, or sleep apnea. And because they don’t get enough sleep these ADHD children are not alert in the mornings, and are tired during the day.
A Canadian study by researchers (M Lyon, M Kapoor, et al) from the University of British Columbia hoped to prove that a synthesized product of the amino acid L-theanine improved sleep quality in ADHD children.
Theanine is an amino acid primarily found in green tea leaves. It can cross the blood–brain barrier—in fact EEG results show L-theanine inducing changes in brain waves. The amino acid makes our brains produce alpha waves, which are associated with relaxation.
ADHD sleep quality improved by amino acid L-theanine
93 children with ADHD completed the UBC trial. They were given four chewable, fruit-flavored L-theanine tablets, or a placebo, every day during the 10-week clinical trial. Their sleep quality was measured, using a wristwatch-like monitoring device measuring sleep activity levels, sleep duration, nocturnal awakenings and sleep patterns. In addition, the parents completed a pediatric sleep questionnaire.
Results showed the children who had taken L-theanine tablets had a significantly higher sleep percentage and reduced nocturnal motor activity compared to the placebo group. They slept longer, with less moving around. This improves their attention, memory, emotion and behavior during the day.
L-theanine supplements are valuable new therapies for helping children with ADHD get enough sleep.
