Cod liver oil comes from the liver of cod, so it carries vitamins A and D. Fish oil comes from the flesh of oily fish and is mainly a source of omega-3 fats. Here are 7 differences that help you choose.<\/p>\n<p>For a general introduction to omega-3 fats, see our <a href=\"https:\/\/nostylelike.net\/en\/jointace-omega-3-guide\/\">omega-3 guide<\/a>. This article focuses only on the comparison.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_Different_sources\"><\/span>1. Different sources<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The first point in cod liver oil vs fish oil is origin. The liver stores fat-soluble vitamins, which is why cod liver oil naturally contains vitamin A and vitamin D. Fish oil is pressed from whole oily fish such as anchovy, sardine and mackerel, then purified and, in better products, concentrated.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Vitamins_A_and_D_the_biggest_difference\"><\/span>2. Vitamins A and D: the biggest difference<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One softgel of <a href=\"https:\/\/nostylelike.net\/en\/product\/now-cod-liver-oil-1000-mg-90-softgels\/\">NOW Cod Liver Oil 1000 mg<\/a> provides 300 mcg RAE of vitamin A, about a third of the daily value, and 400 IU of vitamin D3, half the daily value. That is a useful small top-up for some adults, but it becomes a problem if you double the dose or stack it with other vitamin products.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Cod_liver_oil_vs_fish_oil_EPA_and_DHA_per_capsule\"><\/span>3.

Long-term excess can cause headache, nausea, liver damage and weaker bones. The adult upper limit is 3,000 mcg a day from all sources combined, including multivitamins and liver in the diet.<\/p>\n<ul>\n<li>Do not combine it with another vitamin A supplement without asking a pharmacist.<\/li>\n<li>Avoid it if you take retinoid medicines such as isotretinoin for acne.<\/li>\n<li>People with liver disease should ask their doctor first.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"5_Cod_liver_oil_vs_fish_oil_in_pregnancy\"><\/span>5. Cod liver oil vs fish oil in pregnancy<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Too much preformed vitamin A during pregnancy can harm the developing baby. A pregnant woman, or one planning a pregnancy, should not start cod liver oil on her own, and the NOW label says it is for adults. If extra DHA is needed in pregnancy, doctors usually prefer a purified fish oil or a dedicated prenatal product.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"6_Cod_liver_oil_vs_fish_oil_who_suits_each_one\"><\/span>6.

Both may increase bleeding tendency with anticoagulants such as warfarin or antiplatelets such as aspirin, so tell your doctor and surgeon. A fishy aftertaste or burping is common and is reduced by taking the softgel with a meal.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Cod_liver_oil_vs_fish_oil_vs_eating_fish\"><\/span>Cod liver oil vs fish oil vs eating fish<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>No supplement replaces a healthy diet. Heart organizations recommend eating oily fish such as sardines, mackerel or salmon twice a week, which provides omega-3 along with protein, selenium and vitamin D.

Cod liver oil offers a small omega-3 dose plus vitamins A and D; concentrated fish oil offers more EPA and DHA without added vitamins.
