confidence 90%New clinical research indicates that omega-3 supplements do not improve memory, cognition, or brain cell loss in older adults at risk for Alzheimer's. While long praised for brain health, some evidence suggests these supplements may even hinder recovery after head injuries. Americans spend over $1 billion annually on these products.
What's confirmed:
- Omega-3 supplements do not improve memory, cognitive function, or brain cell loss.
- Fish oil supplements may not prevent Alzheimer's-related decline.
- Americans spend more than $1 billion annually on fish oil supplements.
- A clinical trial published in eBioMedicine found no improvement in brain health for older adults at risk of Alzheimer's.
Still unconfirmed:
- EPA in fish oil may weaken blood vessel stability and disrupt healing signals in people with repeated mild head injuries.
- Omega-3 supplements are linked to faster cognitive decline in older adults.
- Fish oil may contribute to harmful protein buildup linked to cognitive decline in those with repeated mild head injuries.
