People can get fish oil from supplements or by consuming fish, especially tuna, mackerel, bluefish, and sardines, among others, which are rich in omega-3 fatty acids. Fish oil supplements might be enriched with vitamins and calcium.
Fish oil is considered beneficial to problems with the heart and blood, which is why some people that have hypertension or high cholesterol levels take fish oil to lower their blood pressure and cholesterol levels. Stroke; heart disease; depression; Alzheimer’s disease; glaucoma; macular degenerations; attention deficit hypertension disorder; menstrual syndrome; diabetes; preeclampsia; asthma; osteoporosis; kidney disease; and dyslexia are some of the conditions that fish oil is believed to benefit. Also, it helps prevent weight loss in people undergoing cancer treatments. Moreover, fish oil is used after heart surgeries, especially heart transplant or artery bypass, to help control blood pressure and healthy kidney function, increasing the chances the body accepts the new heart.
The way people prepare fish is important, and baked or boiled fish is far more preferable than having fried fish, which nullifies all benefits of fish oil, and increases the risk of heart disease.Fish oil contains docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which are listed under omega-3 fatty acids. Omega-3 fatty acids cannot be produced by the body in any way. However, all the beneficial effects of fish oil, as described before, are owed to DHA and EPA, which are induced in fish oil supplements.
