3. Fish Oil
Fish oil is a supplement that is extracted from the tissue of deep sea fish like trout, sea bass, mackerel, tuna, sardines, herring and even oysters. Fish oil contains high amounts of essential vitamins and minerals, and is purported to provide a wide range of health benefits like treatment of depression, anxiety, diabetes, macular degeneration and high cholesterol. To extract fish oil, raw fish is steam-cooked, then wet-pressed to separate the flesh from the liquid. The oil is then collected and contained in capsules.
Fish oil can help with weight loss, and is suggested during pregnancy to provide beneficial nutrients to both mother and baby. It’s also said to decrease the risk of cardiovascular disease, lower blood pressure, prevent plaque build-up in the arteries, boost the immune system, relieve Celiac disease and other gastrointestinal disorders, treat ADHD (attention deficit hyperactivity disorder) and improve skin conditions like acne, eczema and psoriasis.
A study published by the National Center for Biotechnology Information found that fish oil is an effective treatment for rheumatoid arthritis due to extremely high levels of the omega-3 essential fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), and can even lead to a reduction in nonsteroidal anti-inflammatory drugs. Fish oil can also be used topically, by simply massaging it into the affected areas.
Omega-3 fatty acids can be found in many different food sources like cold-water fish, flaxseeds, soybeans, tofu and walnuts, however it’s much quicker and more beneficial to take fish oil supplements in order to get a higher concentration. Fish oil is generally considered very safe, however, supplements can occasionally cause such side effects like bad breath, burping, nausea, diarrhea, rash, and heartburn. These side effects are more likely to occur at higher doses.
