Do omega-3 levels correlate with Alzheimer’s disease?

What do your omega-3 levels say about your risk for Alzheimer’s disease (AD)? A recent study found a relationship between blood omega-3 DHA levels and development of AD.

Study Summary

The study, which followed 1,490 participants (aged ≥65 years old) without dementia, found that:

  • Those with the highest levels of blood DHA had a 49% lower likelihood of developing AD, compared to those with the lowest levels.
  • Those with the highest levels had an estimated extra 4.7 years of Alzheimer’s-free living compared to those with the lowest levels.
  • The benefit of high blood DHA was significant for those with increased genetic susceptibility to AD.

The Hearty Take

At Hearty, we believe that higher DHA levels may protect from Alzheimer’s disease and contribute to enhanced brain health, regardless of genetics. DHA is found in fatty fish like salmon, sardines, as well as caviar, and algae. Consuming more dietary DHA increases blood levels of DHA. If you are interested in supplementing or having your levels tested, reach out to your physician!
