As omega-3 fats exert anti-inflammatory and antioxidant actions, they also promote joint comfort and mobility by reducing pain, stiffness, and soft tissue swelling. This helps support longevity and independence as you age (since having mobile joints will allow you to move with ease) and also helps ease joint discomfort associated with arthritis. 

In a 2020 Mediterranean Journal of Rheumatology review, scientists analyzed a number of clinical studies that found that increasing omega-3 intake helped reduce morning stiffness, tenderness, and swelling6 of joints in rheumatoid arthritis patients. Researchers hypothesize that these healthy fats may help modulate the autoimmune response, and can therefore be used to help manage RA symptoms.
