DHA (docosahexaenoic acid) is a crucial omega-3 fatty acid that makes up about 8% of brain weight and supports brain structure and function. Research has shown that DHA can improve cognitive function, reduce inflammation, and may help prevent neurodegenerative diseases like Alzheimer's.
Studies have found that higher DHA levels are associated with better memory, faster information processing, and improved problem-solving skills. For developing brains, DHA is even more critical, as it supports neural development and cognitive abilities in infants and children.
While the body can produce small amounts of DHA from other fatty acids, consuming DHA directly from food sources or supplements is the most effective way to increase levels in the brain. Foods rich in DHA include fatty fish like salmon, mackerel, and sardines, as well as algae-based sources for vegetarians and vegans.
