Docosahexaenoic acid (DHA) is a primary structural component of the human brain, cerebral cortex, skin, and retina. While EPA focuses heavily on systemic inflammation, DHA is crucial for neuroplasticity, memory retention, and cellular membrane fluidity. It is vital during fetal neurodevelopment and is widely studied for its role in preventing cognitive decline in aging populations.

Clinical Summary

Strongly supported for cognitive maintenance, maternal/infant health, and ocular support. It does not lower systemic inflammation as aggressively as EPA but is vital for structural cellular health in the brain.

Dosage Guidelines

500mg to 1,000mg daily for cognitive and general structural health.

Safety & Side Effects

Similar to EPA; mild gastrointestinal discomfort or fishy aftertaste.

Known Interactions

May have additive effects with antihypertensive and anticoagulant medications.
