Holland & Barrett's Omega 3 Fish Oil Concentrate 1000mg capsules are a dietary supplement that contains pure fish oil to provide a concentrated source of omega-3 fatty acids. These capsules are formulated to deliver adequate quantities of essential fatty acids, which are nutrients that are not naturally produced by the human body and need to be obtained from food sources. Omega-3 fatty acids, such as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), are known for their numerous health benefits. They play a crucial role in supporting cardiovascular health, brain function, and overall well-being.
