When older adults with memory problems eat more omega-3 fats from fish or supplements, their bodies show less of a type of cell damage linked to aging and brain decline.

For people with early-stage Alzheimer’s, taking a specific fish oil supplement for 6 months might help them think a little better and function more normally—but only if their blood has low levels of a chemical called homocysteine before they start.
