Evidence of omega-3 related to Developmental Coordination Disorder/Dyspraxia & Attention Deficit/Hyperactivity Disorder Omega-3 DHA and EPA for Cognition, Behavior, and Mood: Clinical Findings and Structural- Functional Synergies with Cell Membrane Phospholipids ( Kidd 2007 ) A double-blind RCT was conducted on 117 children ages 5-12, using a mixed omega-3/omega-6 supplement versus an olive oil placebo. ( Freeman, Hibbeln et al. 2006 ) The supplement was 80-percent fish oil and 20-percent evening primrose oil, with a 4:1 omega-3 to omega-6 ratio.
