Cod liver oil: Rich in natural omega-3s
Cod Liver Oil 1000mg from EssentialSeries is a dietary supplement in softgels, made from natural cod liver oil, which is naturally rich in a fat with a high content of natural omega-3 fatty acids (polyunsaturated), making it an excellent source of essential nutrients for the Western diet.
Cod is a fish species, usually small in size, that lives in cold northern seas where the water is clean and has a low content of marine biocomponents. This, combined with the small size of cod, means the fish’s meat and organs have very low natural levels of metals and contaminants, unlike larger oily fish.
This supplement provides a high concentration of omega-3s and vitamins naturally.
Natural source of essential fatty acids

Cod liver oil is naturally high in omega-3s
Cod, despite being an extremely lean white fish, has a liver that stores a large amount of fat in the form of oil rich in polyunsaturated fatty acids, especially from the n-3 or omega-3 series (Eicosapentaenoic Acid or EPA and Docosahexaenoic Acid or DHA).
Cod liver oil was widely used at the end of the last century, given raw to children to improve their development thanks to its great nutritional richness. Unfortunately, cod liver oil has an intense and unpleasant taste.
HSN’s softgels have no taste and deliver all the benefits of the best cod liver oil.
Provides fat-soluble vitamins naturally present in its composition
In cod liver, and its oil, there are vitamins with a fat-soluble profile, meaning they mix with fat; these vitamins are excellent nutrients for overall health, not to mention essential.
The supplement based on cod liver oil could be considered an excellent source not only of essential fatty acids but also of vitamins such as vitamin A (retinol) and vitamin D3 (cholecalciferol).
These vitamins are not industrially added to the supplement, they are natural, present in the natural cod liver oil included in the softgels you take.
Obtained through gentle processing of the raw material
The integrity of the oil used to make the supplement is very important. Oils obtained through intense heating degrade and spoil, which can cause omega-3s to oxidize and generate compounds with negative health effects.
At HSN, we strictly control the production process of cod liver oil.
We obtain the oil by steaming cod livers, which makes them 'sweat,' and after a subsequent pressing, the pure and intact oil is mechanically extracted without degradation.
We guarantee the best raw materials in HSN dietary supplements.
Manufactured following the highest quality and safety standards
The entire manufacturing chain of the supplement is controlled.

In convenient softgels that are easy to swallow. Smooth coating
Capsules, softgels, and tablets can sometimes be hard to take due to their size.
Although Cod Liver Oil softgels are quite large because of their high concentration, you don’t need to take a large daily amount.
While other companies don’t properly control the oil density they use and offer 500 mg softgels that require you to take up to 6 a day, our 1000 mg softgels are optimized, and you only need 2 daily to reach the recommended dose.
Thanks to the extra smooth coating agent treatment, you won’t have trouble swallowing the softgels, making them easy and comfortable to use.
Excellent way to take Vitamins and Omega-3
Cod liver oil is a source of omega-3 fatty acids and fat-soluble vitamins.
Among the long-chain polyunsaturated fatty acids in this family, EPA and DHA stand out.

Docosahexaenoic Acid (DHA)
DHA is docosahexaenoic acid, with 6 double bonds (desaturations) in its carbon chain.
- Docosahexaenoic acid helps maintain normal brain function.1
- Docosahexaenoic acid helps maintain normal vision.1
Eicosapentaenoic Acid (EPA)
EPA is eicosapentaenoic acid, with 5 double bonds (desaturations) in its carbon chain.
- Eicosapentaenoic and docosahexaenoic acids help maintain normal heart function.2
It also contains high amounts of vitamin A and vitamin D.
Vitamin A
Contributes to the maintenance of mucous membranes, skin, normal vision, and normal functioning of the immune system.
Vitamin D
Very important for bones, as it contributes to maintaining normal blood calcium levels and to the normal absorption and use of calcium and phosphorus. This means:
Vitamin D helps maintain bones under normal conditions.
Do I need to take cod liver oil?
Cod liver oil, being animal-derived, is not suitable for vegans, but it’s ideal for people who, either because they don’t like it or don’t have time to cook, consume less than 4 servings of oily fish per week.
It’s also very suitable for athletes who undergo high-intensity training loads.

And if I’m vegan, what options do I have?
If you’re vegan, your need to consume omega-3 increases, since vegetarianism typically provides only sufficient amounts of ALA, which is not adequate compared to the daily required intake of EPA and DHA.
We offer a product of Vegan Omega-3 derived from microalgae oil cultivated under optimal controlled conditions.
Can I combine it with other products?
Cod liver oil complements any other dietary supplement and can be used with many types of products.
One of the most common recommendations is the classic stack with Omega-3, which consists of using this product together with:
B-50 Complex + Creatine Monohydrate + Evowhey 2.0
