Omega-3 supplementation involves taking dietary supplements that contain omega-3 fatty acids, which are essential nutrients that have been shown to have numerous health benefits. Omega-3 fatty acids are commonly found in fish oil, as well as in certain plant sources such as flaxseed and walnuts. Numerous studies have shown that omega-3 supplementation can help reduce inflammation, improve heart health, lower blood pressure, and support cognitive function. In particular, the two main types of omega-3 fatty acids found in fish oil supplements - EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) - have been linked to a variety of health benefits. Overall, omega-3 supplementation is recommended for individuals who do not consume enough fish in their diet or who have specific health concerns that may benefit from the anti-inflammatory and cardioprotective effects of omega-3 fatty acids.
