They are integral for brain function, contributing to cognitive development and mental health improvements, such as reducing symptoms of depression. Omega-3s can be found in sources like fatty fish, flaxseeds, and walnuts. Additionally, these fatty acids play a role in joint health, potentially alleviating symptoms of arthritis.
