What is the difference between cod liver oil and omega-3 supplements?
And the differences between fish oil and cod liver oil supplements?
The main difference between the two is that cod liver oil contains vitamin A.
Fish meat does not contain vitamin A, hence why fish oil generally tends to have very little. On the other hand, cod liver oil contains large amounts of vitamin A, especially when taken in liquid form.
You should always consume both fish oil and cod liver oil supplements in moderation. High doses can increase the risk of bleeding and obstruct proper control of blood sugar levels in diabetic individuals.
What is the recommended dosage of cod liver oil?
|Group||Recommended dosage (ml)|
|Children under 12||2 ml per day|
|Children aged 12 to 18||5 ml per day|
|Women over 18||5-10 ml per day|
|Men over 18||10-15 ml per day|
Capsules are particularly helpful with dosage, with approximately 500 mg of cod liver oil in each. The recommended capsule intake is therefore as follows:
|Children||One capsule twice a day|
|Adults||Two capsules twice a day|
What are the symptoms of a cod liver oil overdose?
There are a number of important factors you need to consider when buying your cod liver oil supplement. They will help you decide more easily which product is best suited for you, and you will be all the more satisfied with your purchase.
Here are the aspects you should take into account:
Not all products sold as cod liver oil are actually 100% made up of this substance. Check the label and look closely at the product formulation.
Some oils available on the market have pleasant and highly digestible aromas. Your choice can also lean towards tasteless or flavoured capsules, which are often covered with gelatine.
Needless to say, go for high-quality products. Many supplements available contain less than 60 percent cod liver oil. The rest is filled with inferior additives, such as low-quality fish or vegetable oils, preservatives, flavour additives, or artificial vitamins.
