Fish oil is oil from the tissues of oily fish, such as anchovies, salmon, sardines, and trout. Fish oil supplements are rich in omega-3 fatty acids, namely docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).

Benefits of Fish Oil

-May support heart health

Multiple risk factors for heart disease  appear to be reduced by consuming fish or fish oil. The benefits of fish oil for heart health include helping:

• lower cholesterol
• lower triglycerides
• reduce blood pressure
• prevent the formation of plaques that harden arteries

Omega-3 may help reduce the severity of and mortality from heart disease. More research is needed to determine if omega-3 has any association with preventing stroke or reducing mortality from stroke.

-Helps Reduce Inflammation

Omega-3 fatty acids in fish oil can partly block many aspects of inflammation. Consuming omega-3s like DHA and EPA through fish oil may reduce long-term inflammation.

Long-term inflammation that lasts months to years raises the risk of chronic illnesses like diabetes and heart disease.

-May Help Slow Bone Density and Muscle Loss 

People naturally lose bone density and muscle mass as they age, which increases the risk of falls and fractures. For example, consuming omega-3s may protect bone mineral density in the spine among older adults.

-Has Been Shown to Manage Arthritis Symptoms

Fish oil may alleviate painful symptoms in people with osteoarthritis (OA) and rheumatoid arthritis (RA). OA wears down the cartilage in your joints, causing chronic pain and disability. OA is the most common cause of arthritis. RA is an autoimmune disease in which the body mistakenly attacks its healthy cells. As a result, you may develop painful, stiff, and swollen joints.

-Helps Protect Eye Health

Some evidence suggests that older adults with high DHA and EPA levels in the outer coating of their red blood cells have a strongly reduced risk of age-related macular degeneration (AMD). AMD causes irreversible vision loss among people older than 60 in the United States. In its later stages, AMD may lead to blurry and wavy areas or the loss of your central vision, which you need to see details straight ahead.
