Esterified omega-3 fatty acids may improve the attention scores for children, says a new study from France and Israel's Enzymotec that appears to highlight the importance of the omega-3 carrier.
Supplementation with omega-3 fatty acids in the phospholipid form resulted in changes to children's fatty acid profile and an increase in Test of Variables of Attention (TOVA) scores amongst children with impaired attention performance participating in the randomised double-blind clinical trial.
"To the best of our knowledge, the randomised controlled trial presented herein is the first short-term intervention study with omega-3 long chain polyunsaturated fatty acids (LC-PUFAs) to show a correlation between these biochemical and cognitive function outcomes," wrote the authors in the American Journal of Clinical Nutrition.
The researchers, led by Jacques Bodennec from the University of Lyon 1 (UMR CNRS 5123), add that supplementation with omega-3 fatty acids in the triacylglycerol form produced different fatty acid profiles and different results. In terms of TOVA scores, improvements were significantly less than observed in children supplemented with the phospholipid form.
