What is DHA (Docosahexaenoic Acid)?
A key marine omega-3 fatty acid important for cell membranes, reported here as a share of the fatty acids in your blood.
DHA is an omega-3 fatty acid concentrated in the brain, eyes, and cell membranes, and it comes mainly from oily fish and fish-oil or algae supplements; this test reports it as a percentage of your total fatty acids. It is usually looked at together with EPA and the omega-3 index. Higher levels typically reflect greater seafood or supplement intake, and DHA is studied in heart and brain-health research, but it is an optional marker rather than a routine screen.
