If you’re trying to increase your intake of omega 3 fatty acids, most people will suggest you try fatty fish or tell you to have cod liver oil. But what if you’re vegetarian and need a vegetarian source of omega 3 fatty acids? As it turns out, in spite of all the hype around fatty fish, there are actually a surprisingly diverse (and delicious) variety of plant-based foods that can get you those precious omega 3 fatty acids! We have a roundup of some of the richest sources you could consider. But first, a lowdown on the different kinds of omega 3 fatty acids and what you need to get in.


Types Of Omega 3 Fatty Acids And Recommended Intake

Depending on the dietary source, your omega 3 fatty acids could come in one or more forms. The most prominent omega 3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). DHA and EPA are mainly found in fatty fish and other kinds of seafood, while ALA is usually available in plant sources.2

ALA itself is an essential fatty acid so you can’t create it in your body, but EPA and DHA can be created using the ALA you consume. Unfortunately, this process of conversion of the ALA into the other two omega 3 fatty acids isn’t very efficient. Which is why it is important to keep yourself plied with a steady stream of omega 3-rich foods if you are vegetarian. It would even make sense to consult a nutritionist who can optimize your diet and ensure you’re getting enough omega 3 fatty acids.3


There isn’t technically a recommended dietary intake level for omega 3 fatty acids set by health or food safety authorities. What you do have to go by, however, is a daily value for fat intake – and that’s set at 65 gm a day for adults.4 So you certainly shouldn’t be having more than this amount across all kinds of fats that you consume, including polyunsaturated and monounsaturated fats and saturated fats. There is, however, a level suggested for ALA intake.

  • Women need to aim at 1.1 gm of ALA daily.
  • Men need 1.6 gm of ALA daily.
  • Pregnant women need 1.4 gm daily while breastfeeding mothers should try and have 1.3 gm of ALA a day.5

Keeping that in mind, here are vegetarian sources of omega 3 you should incorporate into your diet.
