Depression and the Benefits of Omega-3 Fatty Acids

Article revised on 17 July 2017

A number of studies have shown that omega-3 supplements derived from fish oil appear to be of benefit in cases of mild or moderate depression. In fact, it seems that depression sufferers have lower plasma levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both of which are omega-3 fatty acids.

The researchers are therefore continuing their research in order to better understand the role that these nutrients play in mood regulation.

In spite of these promising results, there is nothing to suggest that the use of omega-3 supplements can replace the measures currently used to treat depression. Depression sufferers should follow the treatment plan prepared by their physician and ask for their advice before taking a supplement.

You can get an adequate supply of omega-3 fatty acids, and their many health benefits, from the foods you eat, without having to rely on supplements. Have at least two servings (75 g or 2 ½ oz) of cold water fish per week to make sure you’re getting enough.

Here are a few examples:

  • Sardines
  • Salmon
  • Herring
  • Trout
  • Mackerel
  • Halibut
  • Tuna
  • Oysters
