When it comes to the brain the importance of long-chain fatty acids is not disputed but once again EPA has come up trumps in a study directly comparing EPA with DHA for cognitive function. In a double blind, cross over trial, EPA and DHA were given to young adults for 30 days, with a 30-day washout period between the two interventions. After each 30-day intervention a number of cognitive tests were carried out to determine changes in brain behaviour and activity. Whilst both the EPA and the DHA treatments were able to increase brain activation, only the EPA intervention translated into greater cognitive performance.
