Omega-6 is an essential fatty acid that the body cannot produce on its own, meaning it must be obtained through diet or supplements. It plays an important role in supporting brain function, healthy skin, and normal growth and development. Omega-6 also contributes to the body’s natural inflammatory response and overall cellular health. Common dietary sources include vegetable oils, nuts, and seeds, and it is often included in balanced omega supplements alongside Omega-3 and Omega-9.
