Your optimum life insurance


If you are searching for an easily absorbed, pure fish oil supplement, QuattroCardio makes a fantastic choice. This supplement supplies no less than 622 mg EPA and 420 mg DHA per capsule – a perfect amount if you're trying to raise the omega-3 content (also referred to as the Omega-3 Index) absorbed by your diet above the advised 8%. Just as important is the way in which these omega-3s are made. The production of the omega-3s in QuattroCardio is based on the use of the mildest method currently available, a unique cold and environmentally-friendly technology which also gets rid of any traces of heavy metals from the raw fish oil.


Co-enzyme Q10 is available in two interchangeable forms, ubiquinone and ubiquinol. Ubiquinol is the best choice. The degree to which ubiquinone can be converted into ubiquinol lessens as we age. It is recommended, therefore, to take a ubiquinol supplement from the age of 35. Ubiquinol is a readily available form of CoQ10 and consequently need not be converted. QuattroCardio provides 100 mg of ubiquinol daily. In food, ubiquinol is mainly found in offal (e.g. pig’s heart, 20 mg/100 g) and, to a much lesser extent, in poultry (e.g. chicken leg 2 mg/100 g) or fish (e.g. trout 1 mg/100 g). Not really significant quantities! Until recently, it wasn't possible to process ubiquinol in a stable form in supplements, which is why most supplements have ubiquinone in them. However, a Japanese company managed to produce a stable form of ubiquinol. We only use these easily absorbed Japanese capsules for QuattroCardio.


Natto is the main component of a traditional Japanese breakfast. It is made of fermented soy beans and is not particularly attractive to Westerners because it has a pungent smell and is quite sticky. Fortunately, the superior form of vitamin K from natto is available as a supplement, i.e. as vitamin K2, the type known as menaquinone 7 (MK-7). MK-7 ensures that you maintain a normal bone structure. QuattroCardio provides a daily dose of 90 μg MK-7 from natto.


There are two types of vitamin D: vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol). D3 is mainly found in oily fish and is identical to the vitamin D produced by the body. That is why vitamin  D3 is used by the body at least three times more efficiently than D2. Vitamin D3 helps maintain a normal bone structure and also plays a role in the normal functioning of the immune system and maintenance of normal muscle function. It could even spare us from the cold. In a nutshell, QuattroCardio provides you with high-quality omega-3, ubiquinol, MK-7 and vitamin D3. The unique composition of this supplement will no doubt benefit your health, and all this at a very affordable price.

Q: What is fish oil?

A: Fish oil is made from the fats of small fish such as mackerel, sardines, herring etc. Fish oil comprises the beneficial fatty acids EPA & DHA, which carry many scientifically proven health benefits. It is commonly used to raise one's omega-3 intake and helps to maintain healthy vision, heart and brain function.

Not all fish oil supplements are equal, with factors such as purity, manufacturing process and fish species determining quality. Many fish oils provide just 30% omega-3, with 18% coming from EPA and 12% from DHA. This means that the remaining 70% of the capsule consists of unnecessary or perhaps even unhealthy fats. Impurities such as heavy metals and PCBs are a common problem among cheap fish oil supplements. 

Even concentrated fish oils are made as ethyl esters, containing 60% to 80% omega-3. Although the omega concentration is higher, these fatty acids are not in a very bioavailable form and still contain up to 40% unnecessary or unhealthy fats.

Highly concentrated fish oils, meanwhile, are extremely rare and contain 90% to 95% omega-3. These are not made as ethyl esters but are available in a superior, more bio-available form, r-triglyceride (rTG). These oils supply the greatest amount of EPA and DHA per softgel and are of the highest purity available. UnoCardio 1000 contains a minimum of 95% omega-3.

Fish Oil Comparison

Q: What makes WHC fish oils different?

A: Ever since Jo Wyckmans founded WHC, his passion has been to supply the “best of the best” omegas on the market. Small-species fish (less prone to absorbing toxins) naturally sourced from the cleanest waters on Earth and concentrated and purified via an environmentally-friendly distillation process, WHC omegas contain the highest proportion of essential fatty acids DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid).

The health benefits of essential fatty acids have been scientifically proven in countless studies over a number of years. WHC’s supplements contain 90-95% omega-3 in a single softgel, equivalent to 3-10 standard fish oil softgels. 

While most concentrated fish oils on the market are in the ethyl ester form (a synthetic fat), WHC's formulas are produced in true r-triglyceride (rTG) form. Research has proven the bioavailability of the r-triglyceride form to be vastly superior – up to 70% greater than ethyl esters.

Q: What are EPA and DHA?

A: EPA and the DHA are the fatty acids associated with the most commonly-cited benefits.

The human body synthesises EPA and DHA poorly, which is why they must be obtained from food or omega supplements. Both EPA and DHA play an essential role in the maintenance of overall wellbeing. A healthy daily consumption of EPA and DHA may vary from 250mg up to 3g. DHA is one of the most crucial fatty acids in the brain and retina of the eye, which accounts for why it contributes to the maintenance of brain health and vision when consumed at 250mg per day. 

In some cases, DHA and EPA have combined benefits. For example, both contribute towards the normal function of the heart (at least 250mg per day) as well as the maintenance of normal blood triglyceride levels (2g/day) and normal blood pressure (3g/day). One should not exceed a supplemental daily intake of 5g of EPA and DHA combined.

Only by regularly eating oily fish, or taking omega-3 supplements such as UnoCardio X2 or UnoCardio 1000, can we achieve a balanced Omega-3 Index of over 8%.

Q: Is cod liver oil a good alternative to fish oil?

A: For many, ‘fish oil’ is synonymous with ‘cod liver oil’. However, the fish oil discussed here has little or no connection with cod liver oil. It is actually quite harmful to consume large amounts of cod liver oil if your goal is to elevate your omega-3 intake. This is because many cod liver oils products contain high levels of vitamin A, which can increase one’s risk of osteoporosis. The European Food Safety Authority clearly stipulates that Europeans already consume sufficient vitamin A via their diet, so this particular vitamin is no longer appropriate for food enrichment and supplements.

Q: What about krill oil?

A: Some people consider krill oil to be a valid alternative to omega-3 fish oil, due to the purported ‘enhanced’ bioavailability of its phospholipid form. As the name indicates, it is derived from krill, tiny crustaceans found in the Arctic Ocean. However, the relatively low dose of EPA and DHA means that it is extremely difficult to significantly elevate your blood plasma levels of omega-3 to have a tangible therapeutic effect. Indeed, krill oil only has around 12% omega-3, 15 times less than is found in WHC fish oils.

In one study comparing manufacturer-recommended doses of rTG fish oil, ethyl ester fish oil, TG omega-3 from salmon oil and phospholipid from krill oil, the Omega-3 Index was increased most dramatically by the rTG fish oil (approx. 58% increase), with krill being the least effective (only 11% increase).

 unocardio vs krill oil

Q: Can’t we just eat oily fish instead of taking supplements?

A: Oily fish is a great source of omega-3s, leading many to wonder whether they need to supplement at all. However, while it’s true that you can get all the omega-3 you need from eating oily fish such as herring or anchovies, the pollution of our oceans means we would do well to somewhat limit our fish consumption. Fish accumulate mercury and other heavy metals over time; they have also been found to contain microplastics, and some fish and shellfish can accumulate illness-causing microorganisms like bacteria and viruses too. A fish oil supplement which has been extensively tested for contaminants is a good alternative, although eating modest quantities of oily fish is still recommended.

In any case, most Westerners do not consume enough omega-3 via their diet, meaning supplementation is required to achieve levels recommended by government and health officials.

Q: What should I look for in a fish oil supplement?

A: When making your fish oil purchase, you should look for a product which contains high levels of EPA and DHA per serving; uses small-species, sustainable fish; is made by a reputable manufacturer who follows good manufacturing practices (GMPs) and has achieved an appreciable rating from the IFOS (International Fish Oil Standards Program); and which contains no, or barely detectable traces of, contaminants.
