Fatty Acid Fish Oil Product.
Fish oil sharpens the brain at all ages, researchers say.
Norman Salem Jr., a researcher at the National Institutes of Health, notes that populations consuming large amounts of fish have low rates of major depression. A lack of fish oil is linked to depression in alcoholics, people with multiple sclerosis and women with postpartum depression. Further, he says, some dieters who reduce overall fat, including fish fat, tend to get depressed. A recent Australian study of 21 depressed patients confirmed that the most severely depressed had imbalances of fatty acids in their blood and cell membranes. Depressed people often have low levels of serotonin.
