EPA (Eicosapentaenoic Acid), also known as icosapentaenoic acid and EPA, is a omega 3 fatty acid, a carboxylic acid which acts as a precursor for prostaglandin 3, thromboxane 3 and leukotriene 5 groups of eicosanoids. It is mostly found in fish oil, but can also be contained in human breast milk. In recent times, sources from microalgae have been preferred, due to the large quantities of toxins contained in fish swimming in polluted waters. Human body can produce EPA out of alpha linoleic acid, but since that ALA is an essential fatty acid, only excess amounts would be converted. EPA has been subject to studies pertaining to the use in treatment of schizophrenia, but it may also lower suicidal tendencies. Further use as breast cancer progression inhibitor is under investigation.
