Algal oil, also known as algae oil or seaweed oil, is an oil extracted from marine algae that is rich in certain omega-3 fatty acids, including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) . It is used for making food, with the purified product almost colorless and odorless, and is also under development as a possible alternative fuel and manufacturing agent. Algal oil is a major source of omega-3 fatty acids, which are essential for the body and provide many health benefits. It is also used as a source of fatty acid dietary supplement, as it contains mono- and polyunsaturated fats, in particular EPA and DHA, both of them omega-3 fatty acids. Algal oil is included as a source of DHA in some infant formula and is generally recognized as safe for this use. Algal oil is also used for biofuel, pharmaceutical manufacturing, massage oil, soaps, and lotions.
