Your body needs a daily supply of Omega 3 to supply the essential building blocks for the brain and nervous system. The many health benefits of the polyunsaturated fatty acids of the Omega 3 family have been recognised for so long that many countries now add Omega 3 Fish Oils to many daily products like milk, spreads, juices and yogurts.

A number of studies have reported that supplementation with Omega 3 fatty acids resulted in an improvement in children attention deficit syndrome, this has led to calls by some for omega-3 supplementation of school children. Indeed, the UK's Food Standards Agency (FSA) last year reviewed the science in this field but ultimately decided against such measures, stating the evidence was insufficient.
But studies like this new randomised, double-blind, placebo-controlled trial, reported below could lead to a rethink in this stance.

Study details
 60 children aged eight to 13 were recruited and randomly assigned to receive daily supplements of 250 mg per day of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) esterified to phospholipid omega-3 (300 mg/d phosphatidylserine) or as triacylglycerol (fish oil), or placebo for three months.

In terms of attention measures, both omega-3 supplemented groups produced improvements in TOVA scores (a measure of attention deficit syndrome), with an increase of 94 per cent in the PL-omega-3 group and 37 per cent in the fish oil group.

No changes were observed in the placebo group.

"Our findings suggest that providing preparations with a high EPA/DHA ratio could affect visual sustained attention performance, even at subgram amounts, in paediatric populations," wrote the investigators.
