Alpha-linolenic acid (ALA) is an omega 3 fatty acid that comes from plant sources, such as flaxseed, and can be converted in the body into longer chains. EPA and DHA are omega 3 fatty acids from marine sources (fish and algae) that are directly biologically active. ALA is suitable for those looking for an alternative to fish oil.

Softgels are a suitable form for oils; they protect against oxidation, are easy to take, and extend shelf life.

Unsaturated fatty acids (such as ALA, linoleic acid, and oleic acid) are fatty acids that are usually liquid at room temperature and are mainly found in plant oils. Saturated fatty acids (such as palmitic acid and stearic acid) are often more solid in structure and are found in animal fats and some plant sources.
