How are memory and omega-3 related?

Memory is one of our most basic cognitive functions. You don't think about it until it starts to fail. Just like a muscle, memory can be trained, but if the brain isn't properly nourished to begin with, the exercises may be less effective.

A healthy brain relies on nutrients – and one of the most important building blocks is DHA (docosahexaenoic acid), an omega-3 fatty acid found naturally in the brain’s structure. In fact, DHA makes up over 90% of the polyunsaturated fatty acids in the brain, especially in the cerebral cortex and synapses – areas central to learning, memory and decision-making [1].

EFSA-approved health claim:

DHA contributes to maintaining normal brain function.

The effect is achieved with a daily intake of at least 250 mg of DHA.

Omega-3 and cognition – what does the research say?

Several studies have investigated the link between omega-3 and brain function. Among other things, research shows that people with a regular intake of fatty fish have better preserved cognitive function compared to people with lower intakes [2].

Another study has shown that DHA supplementation can improve both memory and reaction time in healthy young adults [3]. So it’s not just older adults who can benefit from omega-3s – younger brains can also be positively affected.

Studies have also observed a link between regular intake of fatty fish and increased volume of gray matter in the brain – an area that is particularly active during cognitive work [4].
