PS is a member of a nutrient class called phospholipids. Phospholipids can be made in the body and are necessary components of cell membranes. PS is found in cell membranes throughout the body but the greatest concentration is found in brain cells. Some studies have shown that PS supplements can increase exercise endurance, improve memory, and relieve depression.
This study included 36 children diagnosed with ADHD but never treated with medications. The children were given either 200 mg of PS per day or placebo for two months. The parents of the children answered questions about their children’s behavior to assess levels of inattention, hyperactivity, and impulsivity—the hallmarks of ADHD—at the beginning and end of the study. In addition, the children underwent memory and mental performance tests.
Symptom scores and performance on memory and mental tests were the same in both groups at the beginning of the study, but marked differences were seen by the end:
ADHD symptom scores improved 32% more in the PS group than in the placebo group, and their overall symptom scores were 34% lower at the end of the study. PS takers also performed better on short-term memory tests, in which they were asked to repeat expanding lists of numbers, and mental performance tests, in which they were instructed to grab a ball in response to specific colored light cues.
“The magnitude of change observed in the present study is clinically important and is associated with a substantially improved functioning and quality of life in school and at home,” the study’s authors said. “Children in the PS group showed improved classroom behavior and social skills, such as a reduction of walking around in the classroom or talking during class. In addition, children in the PS group showed improvements in putting things back in their proper places at home.”
