Take an Omega-3 Supplement
Omega-3 fatty acid supplements, particularly DHA (docosahexaenoic acid), support cognitive function and overall brain health. Fish oil and krill oil are common sources of docosahexaenoic acid.
DHA facilitates the activity of neurotransmitters, while increasing the number of neurotransmitter receptors. In one research study, fish oil supplements improved the working memory of adults by nearly 25%.
