Fish oil supplements are one of most popular supplements taken today. According to a 2010 survey by ConsumerLab.com, nearly 74 percent of respondents took fish oil supplements daily. The supplement is commonly taken for heart health benefits as well other factors. Though sold without a prescription and easily available, always consult a medical professional before taking any type of supplement. The U.S. Federal Drug Administration does not regulate fish oil and other supplements.
Definition
Fish oil contains two types of omega-3 fatty acids, eicosapentaenoic acid or EPA and docosahexaenoic acid or DHA. The body requires essential fatty acids, but does not produce them on its own. A person must receive omega-3 fatty acids through diet. Fatty acids are essential for brain function and nerve development. Also known as polyunsaturated fatty acids, omega-3 fatty acids come from fatty fish such as tuna, herring and lake trout. These fish gain the omega-3 acids by eating algae.
Benefits
Fish oil is effective for lowering triglycerides, according to MedlinePlus. These fatty substances are found in the blood and contribute to high cholesterol. The website reports fish oil is most likely effective for reducing heart attacks and heart disease. Fish oil is a natural blood thinner and prevents blood clots from forming. Besides being a heart-healthy supplement, fish oil is considered a "brain food," because people with attention deficit hyperactivity disorder, depression and even Alzheimer's disease have claimed improvement due to the supplement, notes MedlinePlus. However, much more research is needed in these areas and not all people agree to fish oils effectiveness.
Side Effects
Burping, belching and bloating are the most common side effects of fish oil. The supplement may give off a fish-like odor to your burps or your breath. Freezing the supplement and taking before meals often decreases the side effect. Fish oil is also a natural blood thinner. Take caution if you are taking blood thinning medications. Because fish oil is a blood thinner you may bruise more often and suffer from nose bleeds. A severe side effect is a hemorrhagic stroke or bleeding in the brain if high doses of fish oil are consumed, notes University of Maryland Medical Center.
Dosage Amounts
Most people should take no more than 3 g of fish oil per day. Occasionally your medical doctor may recommended taking 4 g if you are suffering from high cholesterol. Effects are not immediate and it may take several weeks to see benefits, advises the UMMC. Dosage amounts for children have not been established. Always consult with a medical professional before taking fish oil supplements.
