The Study
Efficacy and acceptability of anti-inflammatory eicosapentaenoic acid for cognitive function in Alzheimer's dementia: a network meta-analysis of randomized, placebo-controlled trials with omega-3 fatty acids and FDA-approved pharmacotherapy.
This study didn’t test the medicine itself—it looked at the results of 52 other studies where people were randomly assigned to take different treatments. It found that one kind of fish oil (EPA) might help memory a bit more than others, but it’s not certain because some of those original studies weren’t done perfectly.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — the fish oil + antioxidant combo had a much bigger effect than any drug, and it was just as safe as a placebo, making it a promising alternative.
- 2Fish oil with added antioxidant (2000 mg EPA) improved memory 3x more than placebo; rivastigmine improved it 1.5x; fish oil had no more side effects than sugar pills; FDA drugs caused more people to quit treatment.

Taking omega-3 supplements, even those high in EPA, is just as safe and easy to tolerate as taking a sugar pill for people with Alzheimer’s, and doesn’t cause more people to quit or have bad side effects than the placebo.
Taking a high dose of a specific fish oil supplement combined with another antioxidant pill every day for a long time may greatly help people with Alzheimer’s disease think more clearly, better than other treatments or no treatment at all.
People with Alzheimer’s who take a high dose of omega-3 fish oil without any extra antioxidants don’t see as much improvement in memory or thinking as those who take the same fish oil along with a special antioxidant called alpha-lipoic acid.
