Omega-3 Fatty Acids There are three different types of omega-3 fatty acids: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). The vitamin company, Ritual, which considers omega-3 fatty acids to be one of its essential ingredients, states that the nutrient is an important part of the cell membrane, and is "also involved in supporting favorable lipid metabolism, immune function and skin health." However, it is mostly EPA and DHA (which are primarily found in fish-based products and oils) that provide these benefits.
ALA is the only one out of the three types that is derived from plants, and Considine says that it "can be found in walnuts, chia seeds and flax seeds." ALA can be converted into EPA and DHA, but only in a limited amount, so it is essential to take vegetarian-friendly supplements to ensure you are getting enough omega-3 fatty acids in your diet.
