Teenagers with the highest omega-3 levels also show improvement in brain function, according to a study from the Open University of the Netherlands. Blood levels of omega-3s were compared to cognitive ability in 266 typical adolescents between the ages of 13- and 15-years-old. Results showed that those teens with the highest omega-3 levels showed higher information processing speed and less impulsivity compared to those with lower omega-3 levels.
