Vegan algae oil is a plant based supplement for those wishing to add more omega-3 into their diet. Algae is a great source of omega-3 essential fatty acids and can contain even higher amounts of EPA and DHA than its fish oil counterparts. In fact, algae is often the omega-3 source for the fish that eat it. These two Omega-3 fatty acids (EPA and DHA) can be hard to come by for vegetarians and vegans unless they supplement with a natural food source such as algae oil. You can consume algae oil either as a capsule, mixed into foods, or take it directly using a dropper.
