The Omega 3 Paradox: What Does It Really Mean for Preventing Dementia? The latest research on fish oil supplements and dementia prevention has revealed a sobering truth about well intentioned health advice gone awry.
A recent study published by researchers at the USC School of Medicine found that high dose DHA supplements, long touted as a preventive measure against Alzheimer's disease, failed to provide measurable clinical benefits.
The study involved 365 men and women between the ages of 55 and 80 who rarely ate fish. Participants were randomly assigned to receive either a daily supplement containing 2,000 mg of DHA or a placebo for 24 months.
