Omega-3 Fatty Acids – Overview
Omega-3 fatty acids are essential fats that the body cannot produce on its own, meaning they must be obtained through diet or supplements. They play a vital role in overall health, especially in heart, brain, and joint function.
There are three main types of omega-3 fatty acids:
1. ALA (Alpha-linolenic acid) – Found in plant sources like flaxseeds, chia seeds, and walnuts.
2. EPA (Eicosapentaenoic acid) – Found in fatty fish such as salmon, sardines, and mackerel.
3. DHA (Docosahexaenoic acid) – Also found in fatty fish and is crucial for brain and eye health.
