Omega-3 Supplement Has No Effect on Alzheimer's Patients
Omega-3 supplements do not slow mental decline in Alzheimer’s patients, according to a new study published in the Journal of the American Medical Association. In this trial conducted by the Alzheimer’s Disease Cooperative Study, Alzheimer’s patients who took an omega-3 supplement showed no benefit in cognition or brain atrophy. Researchers randomly assigned 402 participants to either a docosahexaenoic acid (DHA) supplement (2 grams per day) or a placebo for 18 months. Fish oil and other fish products are often touted for their omega-3 fatty acid—specifically DHA—content.
