Inflammation is a natural body response, but chronic inflammation can cause health issues. Omega-3 fatty acids help manage this inflammation. They may reduce the risk of chronic diseases.
Anti-inflammatory Mechanisms of Action
Omega-3 fatty acids’ anti-inflammatory effects come from their ability to control the body’s inflammatory processes. They do this by affecting the production of eicosanoids. These are signaling molecules in the inflammatory response.
“Omega-3 fatty acids have been shown to reduce the production of pro-inflammatory cytokines, exerting an anti-inflammatory effect.”
Natalie L. Simon, MD
By reducing pro-inflammatory eicosanoids and cytokines, omega-3s help control excessive inflammation. This is key for a balanced immune response. It may also reduce the severity of inflammatory conditions.
