Omega-3 fatty acids are essential polyunsaturated fats that play a vital role in maintaining overall health. Since the human body cannot produce them naturally, they must be obtained through diet or supplements. The main types of omega-3s are ALA (alpha-linolenic acid), found in plant sources like flaxseeds and walnuts, and EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), mainly found in fatty fish such as salmon, mackerel, and sardines.

These healthy fats are crucial for heart health, as they help lower triglycerides, reduce inflammation, and support healthy blood pressure levels. Omega-3s also promote brain function, improving memory and cognitive performance while reducing symptoms of depression and anxiety. Additionally, they support eye health, joint flexibility, and fetal development during pregnancy.
