This umbrella review analyzed nine previous systematic reviews covering 14 randomized controlled trials on whether omega-3 fatty acid supplementation can help protect against cognitive decline in people without dementia or with mild cognitive impairment. Using the Mini Mental State Examination as the main measure of cognition, the pooled results showed a small but statistically significant benefit from supplementation. The findings were consistent across studies, even though they varied in dose, treatment length, and participant characteristics.
Interestingly, the review did not detect a dose–response or duration–response relationship. In other words, higher amounts or longer periods of supplementation did not translate into greater cognitive benefits. This suggests that omega-3s may act through a threshold effect – once a certain level is reached in the body, additional intake provides no further gain.
Overall, the study concludes that while omega-3 supplementation alone is not a cure, it does offer modest cognitive protection and should be considered as part of a broader lifestyle strategy to maintain brain health. Combined with diet, exercise, good sleep, and mental stimulation, omega-3s may contribute to slowing age-related decline.
