Can flaxseed oil protect the aging brain? new trial targets APOE4 carriers

NCT ID NCT07392723

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a daily dose of flaxseed oil (alpha-linolenic acid) can slow memory loss and protect brain blood vessels in older adults with mild cognitive impairment and the APOE4 gene, which raises Alzheimer's risk. Twenty participants will take either the oil or a placebo for six months. Researchers will measure changes in thinking skills and brain scans.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Alpha-linolenic acid (ALA), also known as flaxseed oil
What this could lead to
If it works, this could point toward a simple, safe dietary supplement to slow memory loss in people at high genetic risk for Alzheimer's.
What could go wrong
This is a very small, early pilot trial with only 20 people. The supplement may not improve cognition or brain health, and results may not apply to everyone.
