Fish Oil May Fight Alzheimer's Disease

Dietary Supplements Helped Protect Brains of Elderly Mice

How Much Does It Take?

There is no official recommended daily allowance of DHA (or any omega-3 fatty acid). If you choose to eat fish, you may want to keep an eye on your intake due to concerns about contaminants such as mercury.

DHA and another omega-3 fatty acid, EPA, are found in fish, eggs fortified with omega-3 fatty acids, and fish oil supplements. Another omega-3 fatty acid, ALA, is found in walnuts, soybean oil, and flax seeds.

What About People?

Swedish researchers are studying the safety and tolerability of omega-3 fatty acids on people with mild to moderate Alzheimer's disease. Two studies are also comparing omega-3 fatty acids with placebos, note Lim and colleagues.

Lim is a postgraduate researcher at the University of California Los Angeles (UCLA). Other researchers included Greg Cole, PhD. He's a UCLA professor of medicine and neurology. Cole is also the associate director for research with the Geriatric Research, Education, and Clinical Center at the Greater Los Angeles Veteran's Administration Healthcare System.

The study appears in The Journal of Neuroscience's online edition for March 23.
