Omega-3 supplements are commonly used by individuals who do not regularly consume fish or who wish to increase their intake of EPA and DHA. Products available on the market include: fish oil, krill oil, micro algae oil, cod liver oil, concentrated EPA and DHA formulations. The correct choice should not be based solely on statements such as “1,000 mg of fish oil” or on general claims such as “high strength” and “maximum absorption”. The most important information is the actual amount of EPA and DHA provided per daily serving.
Omega-3 fatty acids have been extensively studied for their potential effects on cardiovascular health, brain function, pregnancy, joint health, and vision. However, not all potential benefits are supported by the same level of scientific evidence. Certain effects, such as the reduction of elevated triglyceride levels, are supported by strong evidence. Other claims, such as the prevention of dementia or general protection against heart attacks, remain less certain. Omega-3 fatty acids should be evaluated according to: the type of fatty acid, the total dosage, the duration of supplementation, the individual’s health history, the population being studied.
Omega-3 fatty acids are a category of polyunsaturated fatty acids involved in several important functions within the human body. They are structural components of cell membranes, contribute to the normal function of the nervous system, and are used in the production of bioactive molecules that influence various cellular processes. The main forms of omega-3 fatty acids are: alpha-linolenic acid, known as ALA, eicosapentaenoic acid, known as EPA, docosahexaenoic acid, known as DHA. Although all these forms belong to the same family of fatty acids, they do not have exactly the same origin, metabolic behaviour, or function within the body.
