Omega-3 fatty acids, and particularly DHA and EPA, are among the most studied nutrients in relation to brain structure and function. They play roles in cell membrane fluidity, signalling, and inflammatory balance.
Why the brain needs DHA
DHA is a major structural component of neuronal membranes. Adequate DHA is important for brain development and ongoing function. Research suggests that DHA status may influence aspects of cognition, mood, and visual function.
Evidence on cognitive outcomes
Studies examining omega-3 supplementation and cognitive outcomes show varied results, with the most consistent benefits seen in individuals with low baseline intake or specific clinical conditions. Importantly, the dose, ratio of DHA to EPA, and duration of supplementation all matter.
Integrating omega-3 into cognitive formulas
In Cognitive Clarity Formula, we include DHA and EPA alongside other nutrients that support psychological function, such as B-vitamins and citicoline. This reflects the reality that brain function depends on multiple systems working together, rather than a single nutrient.
