Can fish oil fix memory loss in Alzheimer’s?
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.

Surprising Findings
Omega-3s with ALA had a cognitive effect size (SMD=3.00) larger than any FDA-approved drug, including rivastigmine (SMD=1.51), donepezil, and memantine.
Most people think only pharmaceuticals can meaningfully treat Alzheimer’s. This study shows a nutritional combo outperforms them all—on a scale where 0.8 is already considered 'large'.
Practical Takeaways
Take a high-dose EPA-dominant omega-3 supplement (1500–2000 mg/day) with 600 mg of alpha-lipoic acid daily if you or a loved one has early-stage Alzheimer’s.

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.
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.
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.
