Supplementation with DHA and the psychological functioning of young adults

Br J Nutr. 2013 Jan 14;109(1):155-61. doi: 10.1017/S0007114512000566. Epub 2012 Apr 13.


The grey matter of the brain contains high levels of the essential nutrient DHA. Although the role of DHA in the developing brain and in dementia has attracted attention, its influence on the brain of the healthy adult has been little considered. A total of 285 young adult females took 400 mg of DHA, in a double-blind, placebo-controlled trial, for 50 d. After 50 d, recently acquired information was more likely to be forgotten by those who had consumed DHA. No significant differences in mood, reaction times, vigilance or visual acuity were found.
