Approximately 60% of the human brain is fat, and a significant portion is comprised of the omega-3 fatty acid DHA. This dependence on fatty acids raises a crucial question: does omega-3 cross the blood-brain barrier to nourish the brain? The answer is a definitive yes, through a highly specific and efficient transport system.

Over 50% of the brain's weight is fat, with a significant portion composed of omega-3 fatty acids like DHA. For these essential fats to reach and support brain tissue, however, they must overcome the formidable blood-brain barrier. So, can omega-3 pass the blood-brain barrier, and if so, how?

The human brain consumes about 20% of the body's energy, but its access to circulating nutrients is strictly controlled by the blood-brain barrier (BBB). This defense mechanism helps explain which fatty acids Cannot cross the blood-brain barrier directly, influencing how our diet fuels and protects cognitive function.
