Supplementing with fish oil has become a common way to improve different areas of health. This oil is linked to better skin and a healthier heart, along with improved mood and focus. But as with any supplement, taking fish oil can have certain side effects. For some people, this might include nausea and vomiting. Be sure to talk to your doctor to determine if fish oil is right for you.
Identification
Fish oil supplements often are derived from fattier fish, including herring, salmon, sardines and anchovies, notes Dr. Adriane Fugh-Berman in the book "The 5-Minute Herb and Dietary Supplement Consult." But even less-fatty fish contain some oil and benefits when eaten in whole food form. Fish oil contains the essential omega-3 fatty acids eicosapentaenoic acid, or EPA, and docosahexaenoic acid, or DHA. These are necessary for proper brain development and nerve function. Supplements now can be found in most grocery stores and purchased online.
Benefits
Though the omega-3s in fish oil are linked to a variety of benefits, one of the main ones is protection against heart disease. According to James Balch in his book "Prescription for Drug Alternatives," fish oil can help to lower triglyceride levels, total cholesterol and balance cholesterol ratio levels. Fish oil also can improve brain function and mood because of its high essential fatty acid levels, notes Balch. Some research shows that supplementing with this oil can help children with symptoms of ADHD. Other benefits include improved skin texture, decreased joint pain and less inflammation.
Nausea and Vomiting
One of the possible side effects of fish oil is nausea, notes Balch. In some people, this can lead to vomiting. Large amounts of any oil taken by itself can cause gastrointestinal discomfort, including nausea, vomiting or heartburn. Taking enteric-coated caplets might reduce gastrointestinal issues since the oil is broken down more slowly later in the digestion process. Also, taking lower amounts of fish oil at a time might eliminate nausea or vomiting.
Considerations
Fish oil now is recommended by a variety of practitioners to improve a number of health issues linked to low omega-3 levels. Still, there are certain situations in which you should not take fish oil, including if you have trouble clotting, are on a blood thinner or are allergic to fish. Also, work with your doctor to determine how much fish oil you should take, especially if you are having issues with vomiting. Vomiting consistently can be a sign of a more serious condition.
