Omega 3: What it is and why it matters
Let’s face it—we hear about Omega 3 all the time. From supplement commercials to nutrition blogs, it’s everywhere. But what exactly is Omega 3, and why should we care?
It is an essential fatty acid. Our bodies require it to function but can’t produce it, so we need to get it from food or supplements. It plays a vital role in every cell of your body and is a cornerstone of optimal health.
The Three Types of Omega 3 Fatty Acids
ALA (Alpha-linolenic acid)
Found mostly in plants, ALA is commonly present in flaxseeds, chia seeds, and walnuts. It’s the most common Omega 3 in Western diets but has to be converted to EPA or DHA to be effective—which doesn’t happen efficiently in our bodies.
EPA (Eicosapentaenoic acid)
This is found mainly in oily fish like salmon, sardines, and mackerel. EPA helps reduce inflammation and supports heart and mental health.
DHA (Docosahexaenoic acid)
Found in fish, DHA is vital for both brain function and eye health, making up approximately 40% of the polyunsaturated fats in your brain!
