9 Health Benefits of Cod Liver Oil
By Ryan Raman
Cod liver oil is a type of fish oil supplement.
It also contains vitamins A and D, both of which provide many other health benefits.
Here are nine scientifically supported benefits of cod liver oil.
1. High in Vitamins A and D
Most cod liver oil is extracted from the liver of Atlantic cod.
Cod liver oil has been used for centuries to relieve joint pain and treat rickets, a disease that causes fragile bones in children (3).
Although cod liver oil is a fish oil supplement, it's quite different than regular fish oil.
Regular fish oil is extracted from the tissue of oily fish like tuna, herring, anchovies and mackerel, while cod liver oil is extracted from the livers of cod.
The liver is rich in fat-soluble vitamins like vitamins A and D, which give it an impressive nutrient profile.
One teaspoon (5 ml) of cod liver oil provides the following (4):
- Calories: 40
- Fat: 4.5 grams
- Omega-3 fatty acids: 890 mg
- Monounsaturated fat: 2.1 grams
- Saturated fat: 1 gram
- Polyunsaturated fat: 1 gram
- Vitamin A: 90 percent of the RDI
- Vitamin D: 113 percent of the RDI
Cod liver oil is incredibly nutritious, with a single teaspoon providing 90% of your daily requirements for vitamin A and 113 percent of your daily requirements for vitamin D.
Summary: Cod liver oil is very nutritious and provides nearly all of your daily requirements for vitamins A and D.
Britain's Prince William interviewed famed broadcaster David Attenborough on Tuesday at the World Economic Forum's annual meeting in Switzerland.
During the sit-down, the 92-year-old naturalist advised the world leaders and business elite gathered in Davos this week that we must respect and protect the natural world, adding that the future of its survival—as well as humanity's survival—is in our hands.
What's more, the accounting firm predicts that another 21 million electric cars will be on the road globally over the next decade due to growing market demand for clean transportation, government subsidies, as well as bans on fossil fuel cars.

Plastic pollution in the world's oceans has become a global environmental crisis. Many people have seen images that seem to capture it, such as beaches carpeted with plastic trash or a seahorse gripping a cotton swab with its tail.
Greenland is melting about four times faster than it was in 2003, a new study published Monday in the Proceedings of the National Academy of Sciences found, a discovery with frightening implications for the pace and extent of future sea level rise.
"We're going to see faster and faster sea level rise for the foreseeable future," study lead author and Ohio State University geodynamics professor Dr. Michael Bevis said in a press release. "Once you hit that tipping point, the only question is: How severe does it get?"
Finally, some good news about the otherwise terrible partial government shutdown. A federal judge ruled that the Trump administration cannot issue permits to conduct seismic testing during the government impasse.
The Justice Department sought to delay—or stay—a motion filed by a range of coastal cities, businesses and conservation organizations that are suing the Trump administration over offshore oil drilling, Reuters reported. The department argued that it did not have the resources it needed to work on the case due to the shutdown.
Most people have heard of the Amazon, South America's famed rainforest and hub of biological diversity. Less well known, though no less critical, is the Pantanal, the world's largest tropical wetland.
Like the Amazon, the Pantanal is ecologically important and imperiled. Located primarily in Brazil, it also stretches into neighboring Bolivia and Paraguay. Covering an area larger than England at more than 70,000 square miles, the massive wetland provides irreplaceable ecosystem services that include the regulation of floodwaters, nutrient renewal, river flow for navigability, groundwater recharge and carbon sequestration. The wetland also supports the economies of the four South American states it covers.

Organizers said 35,000 people marched through the streets of the German capital on Saturday to say they're "fed up" with industrial agriculture and call for a transformation to a system that instead supports the welfare of the environment, animals and rural farmers.

If you have ever considered making the switch to an environmentally friendly electric vehicle, don't drag your feet. Though EV prices are falling, and states are unveiling more and more public charging stations and plug-in-ready parking spots, the federal government is doing everything it can to slam the brakes on our progress away from gas-burning internal combustion engines. President Trump, likely pressured by his allies in the fossil fuel industry, has threatened to end the federal tax credits that have already helped put hundreds of thousands of EVs on the road—a move bound to harm not only our environment but our economy, too. After all, the manufacturing and sale of EVs, hybrids, and plug-in hybrids supported 197,000 jobs in 2017, according to the most recent U.S. Energy and Employment Report.
