Oct. 18, 2002 -- It may sound fishy, but researchers say taking a daily fish-oil supplement may boost the effectiveness -- or even replace -- antidepressants for treating depression in some people.

In a new study, people who added a daily dose of omega-3 fatty acids to their regular antidepressant treatment had significant improvement in symptoms, including anxiety, sleeping problems, sadness, decreased sexual desire, and suicidal tendencies.

Although there are many effective treatments for depression, most only work in a limited number of patients or have significant side effects that prompt users to stop taking them. That's inspired researchers to look for new ways to treat the mental illness or increase the effectiveness of existing treatments.

1 gram works, 2 doesn't, 4 works great? Clearly some randomness in there, so this isn't confirmed, but still interesting.
