Fish oil tablets are a popular dietary supplement that contains omega-3 fatty acids, which are essential for maintaining good health. They are typically made from fish oil extracted from oily fish such as salmon, mackerel, and sardines. These tablets are an excellent source of EPA and DHA, two types of omega-3 fatty acids that are known to have numerous health benefits. They are believed to reduce inflammation, lower blood pressure, improve brain function, and promote healthy skin and eyes.
