Fish Oil Side Effects

Fish oil is the oil made out of the tissues of oily fish. It is highly beneficial for health as it contains eicosapentaenoic acid (EPA), omega-3 fatty acids, and docosahexaenoic acid (DHA), precursors to eicosanoids that is functional in reducing inflammation throughout the body. The Omega 3 fatty acids present in the fish oil are known to be beneficial for people suffering from heart disease, high blood pressure, rheumatoid arthritis, asthma, bipolar disorder and cancer. Fish oil also contains DHA that is highly useful for the body. Owing to so many benefits, the oil has now become an important part of people’s life, as a daily supplement. As a coin has two sides, it has been found that fish oil too has some side effects. Fish oil side effects are not hazardous initially, but if you are taking a consistent dose or an overdose, the consequences can be perilous.
