fish oil peptide FAQ

Omega-3 supplements are often made from fish or krill and sometimes referred to as fish oil or krill oil supplements. Some omega-3 supplements are made from algae and may be called algal oil supplements. Supplements made from algae are considered vegetarian. Omega-3 supplements have one or more omega-3 fatty acids in them. These fatty acids are an important part of many cells in your body, especially in your eyes and brain. Omega-3 fatty acids give you calories for energy and help with many functions in your heart, blood vessels, lungs, and immune system, and with certain hormones. In the United States, most people get enough omega-3 fatty acids from their diet. Omega-3 fatty acids come in many forms. One common form is alpha-linolenic acid (ALA) that is mostly found in plants and plant oils, such as seeds, nuts, flaxseed oil, and canola oil. Two other common omega-3 fatty acids are docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). These two fatty acids are found in krill, fish (especially fatty fish, such as cod, salmon, tuna, and mackerel), and some fortified foods, including eggs, yogurt, juices, milk, soy drinks, and baby formulas. For most adults, the recommended daily intake of ALA should be between 1.1 and 1.6 grams (g). It is rare not to get enough ALA from your diet. For most adults, there is no recommended daily intake for DHA or EPA. However, there are recommended intakes for some adults, such as those with heart disease or those who are pregnant or breastfeeding (see the Sources section for more details). Most people can get enough DHA and EPA by eating two to three servings of low-mercury fish each week. Talk with your health care provider about the best way to get the recommended amounts of omega-3.

One small study found that krill oil, like omega-3s in general, could improve rheumatoid arthritis and osteoarthritis symptoms such as pain, stiffness, and functional impairment. It also lowered levels of C-reactive protein, a marker for inflammation in the body that's been linked with heart disease. In addition, krill oil eased symptoms of premenstrual syndrome in another small study.

Experts do not recommend this, however, since safety or efficacy of krill oil in pregnant women and children has not been proven. As krill oil becomes more popular, some scientists are concerned about the environmental impact of large-scale krill harvesting.
