Frequently asked questions about cod liver oil capsules

Finding the right supplements to add to your diet can often lead to a lot of questions. Don't worry though because we've answered some of the most frequently asked queries surrounding cod liver oil capsules right here.


Are cod liver oil capsules worth taking?

It may not be essential to take cod liver oil capsules; however, adding them to your diet can help ensure you're fueling your body with all the nutrients it needs to maintain a balanced diet.

Cod liver oil primarily contains vitamins A and D as well as important Omega-3 fatty acids which have been linked to maintaining a healthy heart and arteries.

That said, perhaps the greatest argument for taking cod liver oil tablets is that they're an effective and simple way for those who tend not to eat fish to ensure they're getting all the important nutrients fish give us, without having to subjective themselves to something they dislike.

However, cod liver oil capsules are only designed to complement your diet and should not act as a complete replacement for actual food and main meals.

It's still worth trying to obtain the nutrients through whole foods every now and then to reap the calorie and protein benefits that come with eating fish.

When should you take cod liver oil capsules?

You can take cod liver oil capsules at any time during the day that works best for you.

This is because the NCCIH, a US government agency that explores complementary and alternative medicine, believes the potential benefits of cod liver oil are not immediate, but instead associated with long-term use.

Therefore, it's not so much about when you should take cod liver oil capsules, but more about the regularity with which you consume them.

Studies have shown, including one of note by Farshbaf-Khalili et al., have found taking fish supplements over several weeks, months, or even years can increase levels of omega-3 fatty acids in the blood, thus suggesting regular intake is best to reap the potential long-term benefits.

What's the difference between cod liver oil and fish oil?

Generally speaking, cod liver oil is just one specific type of fish oil.


Whereas general fish oil is often extracted from the flesh of various small, cold-water fish such as mackerel or sardines, cod liver oil comes from, as its name suggests, the liver of cod fish.

As a result, cod liver oil tends to contain both vitamins A and D but lower Omega-3 content as cod is typically less fatty than other fish like tuna and mackerel.

What ingredients should you look for in a cod liver oil capsule?

The two key nutrients to look out for when deciding upon the right cod liver oil capsules for you are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), two Omega-3 fatty acids which have been linked to healthy aging and development.

In fact, some studies suggest both EPA and DHA are key to correct fetal development, including neuronal, retinal, and immune function.

Moreover, EPA and DHA have also been linked to improved cardiovascular functioning, including reducing the risk of inflammation, peripheral artery disease, major coronary events, and anticoagulation.


You may also want to keep an eye out for vitamins A and D, both of which come with several potential benefits.

For instance, vitamin A is commonly associated with improved vision and eye health, while vitamin D is linked to the regulation and absorption of calcium and phosphorus, plus the running of normal immune system function according to the National Insitute of Health.
