Can Omega-3 Fatty Acids Slow Down Cognitive Aging?

Omega-3 polyunsaturated fatty acids (n-3 PUFA) may help prevent cognitive decline and dementia.

Recent studies suggest that consuming fish or fish oil (n-3 PUFAs) can reduce the risk of mild cognitive impairment and Alzheimer’s disease (Welty FK, 2022).

Specifically, taking docosahexaenoic acid (DHA) supplements benefits those with mild cognitive impairment, but not those with Alzheimer’s.

In healthy individuals with coronary artery disease, 3.36 grams of EPA and DHA daily slowed cognitive aging by 2.5 years.

However, results from various studies differ due to factors like dosage, trial length, and individual characteristics.

Those with early memory issues, a family history of dementia, or coronary artery disease should consider fish intake and n-3 PUFA supplements, especially if they carry the apolipoproteinE4 gene.

For a high-quality source of Omega-3, consider Better Fish Oil.
