DHA, in particular, is vital for the development and function of the hippocampus, the brain region primarily responsible for memory formation and retrieval. Research suggests that adequate intake of omega-3s can improve both short-term and long-term memory, as well as verbal memory and learning abilities. For instance, a study published in the journal “Alzheimer’s & Dementia” found that higher levels of DHA in the blood were associated with a lower risk of developing Alzheimer’s disease and slower rates of cognitive decline.   



• Focus: Omega-3 fatty acids play a critical role in brain cell communication and neurotransmitter function, both of which are essential for maintaining focus and attention. EPA has been linked to improved attention span and reduced symptoms of ADHD in some studies. By supporting healthy brain cell membranes, omega-3s facilitate efficient signal transmission, allowing for better concentration and reduced mental distraction. Research in the “Journal of Attention Disorders” indicated that omega-3 supplementation could lead to modest but significant improvements in attention and working memory in children with ADHD.   



• Cognition: Beyond memory and focus, omega-3s contribute to overall cognitive health. They possess anti-inflammatory and antioxidant properties, protecting brain cells from damage caused by oxidative stress and inflammation, both of which are implicated in cognitive decline. Studies have shown that regular consumption of fatty fish is associated with a lower risk of age-related cognitive decline and dementia. A meta-analysis published in “PLoS One” concluded that omega-3 supplementation had a beneficial effect on cognitive function in older adults.   

How to Incorporate Fatty Fish into Your Diet:

Aim to include at least two servings of fatty fish per week. You can bake, grill, pan-fry, or steam your favorite types.
