Italy and Germany are the two largest single markets for dietary supplements in Western Europe, followed by countries such as the United Kingdom and France.​ Research for analyzing the effects of omega-3 supplements are being carried out in almost every region across the globe. The systematic reviews of health benefits of omega-3 dietary supplements have resulted in the product being accepted as safe for consumption by the EU-supported group of international.​ Omega-3 containing dietary supplements are proving to be a major attraction for almost every manufacturer, owing to their assistance in maintaining bone health and heart health in both the geriatric as well as younger population segments. Commonly used dietary supplements that contain omega-3s include fish oil (which provides EPA and DHA) and flaxseed oil (which provides ALA). Algae oils are a vegetarian source of DHA.​

According to dietary guidelines, Germans are encouraged to eat 150- 220 g of fish per week, in order to consume enough essential omega-3 fatty acids. However, despite a high level of awareness, only a few Germans consume enough fish. More middle-aged women in Germany are deficient in omega-3 due to which they are at an increased risk of heart disease. Such risk factors, in turn, are leading to women in the country increasingly purchasing omega-3 products to avoid health risks. High awareness and product knowledge have positioned Germany as the major omega-3 product consuming country in this region. Furthermore, the large presence of health stores in Germany is directing consumers to purchase the products from this channel. Moreover, Germany’s big drugstore retail chains, such as DM, Rossmann, and Müller  sell a borad range of omega-3 products, thereby catering to the needs of the consumers in the country.
