May reduce inflammation

Inflammation is your immune system's response to infection and injury. Chronic inflammation, on the other hand, has been linked to diseases such as obesity, diabetes, depression, and heart disease. Reducing inflammation can aid in the treatment of certain illnesses' symptoms. Because fish oil has anti-inflammatory qualities, it may aid in the treatment of chronic inflammatory disorders.

Increased weight or stress, for example, can sometimes contribute to greater levels of inflammation. Fish oil was reported to suppress the generation and gene expression of inflammatory chemicals called cytokines in two earlier investigations, one in adults with obesity and one in those undergoing stress. Furthermore, fish oil supplements can dramatically reduce joint pain, stiffness, and medication requirements in persons with rheumatoid arthritis, a condition that causes joint discomfort. While inflammation is also a cause of inflammatory bowel disease (IBD), there is no convincing evidence that fish oil helps its symptoms.
