Docosapentaenoic acid (DPA) is an omega-3 fatty acid found in fish oils, marine organisms, and in smaller amounts in some plant oils. While research into DPA has lagged behind the more widely studied omega-3s, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), there is emerging scientific interest in its role in brain health and cognitive function. DPA is structurally similar to both EPA and DHA and serves as a metabolic intermediary between them. Recent preclinical studies suggest DPA may have neuroprotective and anti-inflammatory properties, and laboratory research has shown it can modulate neuronal signaling and reduce oxidative stress in the brain. However, direct human studies specifically examining DPA supplementation for memory and brain function are extremely limited. Most clinical research on cognitive support with omega-3s focuses on DHA and, to a lesser extent, EPA, with DPA often present only as a minor component in supplements. A few observational studies have noted correlations between higher blood levels of DPA and better cognitive outcomes in older adults, but these findings are preliminary and do not establish causation. No large-scale randomized controlled trials (RCTs) have directly tested DPA supplementation for memory or brain health. Therefore, while there is a plausible scientific rationale based on DPA’s biological activities and some associative data, the direct evidence for its use in supporting or treating memory and brain function in humans remains weak. More focused clinical research is needed to clarify DPA’s specific benefits in this area.
