Cod liver oil is a common supplement and ingredient in an array of products, including skin lotions, food supplements, and other cosmetics. Most notably, however, it is also used as a dietary supplement by individuals hoping to improve their cardiovascular health. This oil contains a high concentration of omega-3 fatty acids, which have been shown to be beneficial for the heart and may help lower blood pressure. In fact, many cardiologists recommend that patients over 50 should consume at least 2 g of omega-3 fatty acids daily, which can be found in just 2 tablespoons of cod liver oil.

Buying Guide

Cod liver oil has been used for a long time because it is good for your health. Ancient Norse people, like the Vikings and other Norse people, used to drink cod liver oil all through the winter. It looks like these people knew what they were talking about. A lot of people call vitamin D the “sunshine vitamin,” and cod liver oil has a lot of it. It is also a great source of vitamin A and omega-3 fatty acids, both of which are important for keeping the body healthy.
We highly recommend the Nordic Naturals Arctic Cod Liver Oil because it is very strong, pure, and has a delicious orange flavor. If you want to buy the best one, we recommend it. But if you want to know more about the benefits of taking cod liver oil and the things you should think about when buying it, keep reading.
Cod liver oil benefits
Omega-3 fatty acids, vitamin A, and vitamin D are all important for health, but most people in the modern West don’t get enough of them in their diets. Cod liver oil is a great way to get all three of these important nutrients.
Several studies show that omega-3 fatty acids have many benefits for the body, such as making the brain and eyes healthier and making the skin look younger. It has been shown to lower the risk of heart disease by lowering blood pressure and triglyceride levels and raising HDL cholesterol levels at the same time. Omega-3 fatty acids have also been linked to a lower chance of getting Alzheimer’s disease and aging-related mental decline.
Vitamin A helps keep your eyes and immune system healthy. Also, it is an important nutrient for both men and women to keep their bones and reproductive systems in good shape in order to have healthy bones and organs. It’s important to remember that the vast majority of experts in the field say that we should get the vitamin A we need for the day from natural sources like cod liver oil since it’s not clear if pills made in a lab offer the same benefits.
The body makes vitamin D when it’s exposed to sunlight, but most people in modern society spend most of their time indoors because that’s what they choose to do. This is a shame because vitamin D helps control how much phosphorus and calcium are absorbed. These are two things that help bones and teeth grow in the right way. Calcium and phosphorus are both very important for healthy bones and teeth. Vitamin D also helps keep the immune system working well, which can help make people less likely to get sick. Some diseases are less likely to happen when you don’t get enough vitamin D.
Cod liver oil features
Form
There are both liquid and pill supplements with cod liver oil in them. In general, liquid options have more omega-3s, vitamin A, and vitamin D per serving than solid ones. On the other hand, the fishy taste can be off-putting, which is why many people choose to add it to a drink that has a lot of other strong flavors. Liquid cod oils should also be kept in the fridge once the bottle has been opened. On the other hand, capsules don’t have to be kept in the fridge, so they can be kept in a more convenient way.
Taste
Cod liver oil often still tastes like cod liver oil, even when it is mixed with other flavors in a drink. In response to this problem, a number of companies are now making cod oil supplements that taste good. Adding flavors like mint, lemon, orange, and other citrus fruits and herbs can hide the taste of cod liver oil and make it easier to take. You could also take the supplement in the form of a capsule, which is less likely to leave your mouth tasting fishy.
Sustainability
Most of the time, people are told to buy cod liver oils that are made in ways that are better for the environment if they can afford the price difference. Most businesses that do this will have gotten certification from the Marine Stewardship Council or other groups that do similar things.
Fermented
Several people make and sell fermented cod liver oil. They say that the traditional way of distilling removes a lot of the essential elements, which businesses then have to add back in a synthetic form. Other producers say that fermenting cod liver oil hurts the omega-3 fatty acids it contains, which reduces the health benefits of the oil and speeds up the rate at which it goes bad. At this point, it’s hard to tell which side is right until more research is done and the results are more clear.
