DHA is found in the phospholipid fraction of the brain and is a major polyunsaturated fatty acid of the brain .It was not known whether supplemental DHA has any effects on the higher functions of the brain in young adults. So, this study was conducted to assess the efficacy of DHA in preventing aggression in adults.
A placebo-controlled double-blind study.
41 young adults.
1.5-1.8 g of DHA daily (n =22) or control oil (n =19).
3 months
DHA therapy caused significant alterations in the extraggression (aggression against others) in comparison to the placebo group, where it was significantly increased (see Fig. 1) (p=0.0029).
The 95% CI difference between the DHA and control groups were found to be -16.8% to -3.0%, respectively.
DHA supplementation significantly prevents extraggression in young adults
