Cod Liver Oil Overview
Cod liver oil is derived from the liver of the Atlantic cod fish. It is a rich source of omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), as well as vitamins A and D.
Cod liver oil is used as a dietary supplement to provide the health benefits of omega-3 fatty acids and vitamins A and D. Omega-3 fatty acids are important for maintaining heart health and can help to reduce inflammation, lower blood pressure and triglyceride levels, and may decrease the risk of heart disease.
While Cod liver oil and fish oil are both sources of EPA and DHA, there are some key differences between the two. For example, cod liver oil is derived from the liver of the Atlantic cod fish, while fish oil is typically derived from the body tissue of oily fish such as salmon, sardines, and anchovies.
Additionally, cod liver oil generally has a stronger fishy taste and smell than fish oil due to its liver source.
Naproxen Overview
-
Prescription naproxen is used to relieve pain, tenderness, swelling, and stiffness caused by osteoarthritis (arthritis caused by a breakdown of the lining of the joints), rheumatoid arthritis (arthritis caused by swelling of the lining of the joints), juvenile arthritis (a form of joint disease in children), and ankylosing spondylitis (arthritis that mainly affects the spine). Prescription naproxen tablets, extended-release tablets, and suspension are also used to relieve shoulder pain caused by bursitis (inflammation of a fluid-filled sac in the shoulder joint), tendinitis (inflammation of the tissue that connects muscle to bone), gouty arthritis (attacks of joint pain caused by a build-up of certain substances in the joints), and pain from other causes, including menstrual pain (pain that happens before or during a menstrual period). Nonprescription naproxen is used to reduce fever and to relieve mild pain from headaches, muscle aches, arthritis, menstrual periods, the common cold, toothaches, and backaches. Naproxen is in a class of medications called NSAIDs. It works by stopping the body's production of a substance that causes pain, fever, and inflammation.
