A study published in eBioMedicine by researchers at Keck Medicine of USC found that participants taking daily omega-3 supplements did not exhibit major cognitive advantages.
Lead investigator Hussein Naji Yassine noted that fish oil supplements do not appear to protect brain health or prevent Alzheimer's disease.
Neurologists clarify that whole foods containing omega-3 remain valuable as part of a balanced diet, emphasizing that supplements should not replace healthy lifestyle habits.
