Nutritional Composition of Fish Oil Supplements
Omega-3 Fatty Acids
Omega-3 fatty acids are a type of polyunsaturated fat that is essential for the body’s overall health. There are three main types of omega-3 fatty acids: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). ALA is mainly found in plant sources like flaxseed and chia seeds, while EPA and DHA are primarily found in fatty fish and fish oil supplements.
EPA and DHA
EPA and DHA are the two most studied and beneficial forms of omega-3 fatty acids. These fatty acids play a crucial role in maintaining heart health by reducing inflammation, lowering triglyceride levels, improving blood vessel function, and preventing the formation of plaque in the arteries. EPA and DHA are also important for brain health, eye health, and overall well-being.
Other Nutrients in Fish Oil Supplements
