The brain has a unique fatty acid composition, and DHA is quantitatively the most important omega-3 fatty acid in the brain. The DHA fatty acid has consistently been shown to have unique and indispensable roles in the brain.
Nutrition plays an important role in brain development and cognitive function. Intake of EPA and DHA is considered particularly important for neuronal development during early infancy where a substantial amount of DHA is accumulated in the brain. This accumulation of DHA continues throughout childhood and beyond.
Numerous studies have also shown the potential protective effect of omega-3 DHA and EPA fatty acids on the incidence of dementia and Alzheimers disease, as well as reduced prevalence of depression.
