Fish Oil for Children – From WHC, The Best of the Best

Fish oils are widely recognised as being important to our health – whatever age we are.

Like adults, most kids are deficient in EPA and DHA, the essential fatty acids found in fish oil. These nutrients are vital building blocks of a child's development, particularly as it pertains to brain health and vision. 

QuattrO3 + PS is an advanced complex specially formulated for youngsters. It integrates readily-absorbable EPA and DHA with vitamin D3, which is needed for the normal growth and development of bone in children, among other things.

Made by WHC, a company world-famous for the purity of their fish oils, QuattrO3 + PS is a safe, natural and effective way of promoting your child’s mental and physical wellbeing.

Do Children Really Need Fish Oils?

Some parents might wonder if their children really need fish oils. Can’t they get all the nutrition they require from milk, fruit, vegetables and protein?

Since our bodies can’t make omega-3 fatty acids, the answer is no: we must get them from oily fish, fish oil supplements or omega-3 foods like walnuts, flaxseeds and egg yolks. Given that most kids turn their noses up at oily fish, it’s no wonder children's fish oils have become so popular!

Omega-3s have many benefits, but their effect on children is especially noteworthy: maternal intake of DHA not only contributes to the normal brain and vision development of the foetus and breastfed infant, but to the normal visual development of infants up to 12 months of age. 

In one 2012 study by the University of Oxford, daily supplements of DHA improved the reading and behaviour of underperforming kids in mainstream primary schools.

‘Our results showed that taking daily supplements of omega-3 DHA improved reading performance for the poorest readers (those in the lowest fifth of the normal range) and helped these children catch up with their peer group,’ said Dr Alex Richardson, senior research fellow at Oxford’s Centre for Evidence-Based Intervention. 

A separate 2016 trial underscored the benefits of fish oils for children, particularly where reading ability was concerned. Previous studies have also underlined the benefits of omega-3 supplements for kids with conditions like dyslexia and ADHD.

Vital Vitamin D

As well as fish oils, QuattrO3 + PS utilises vitamin D3 to help kids realise their full potential. Vitamin D3 – which Public Health England say we should all consider supplementing with during the sun-starved autumn and winter months – is of particular benefit to youngsters insofar as it promotes growth, contributing to bone development, muscle function and healthy teeth.

Important though the Sunshine Vitamin undoubtedly is, many children are still deficient. According to a study published in Pediatrics in 2017, there was an increase in the rate of vitamin D deficiency among kids between 2000 and 2014. Another study published in the Journal of Steroid Biochemistry & Molecular Biology found that almost half of newborns are deficient in vitamin D, with the number rising to 62% during winter.

Vitamin D deficiency among young people is doubly troubling, since new analysis published in the British Medical Journal suggests vitamin D supplements "could spare more than three million people from colds or flu in the UK each year".

QuattrO3 + PS contains 400 i.u. (10 mcg) of vitamin D3, the official daily recommendation by the Department of Health.

Pure and Eco-Friendly Manufacturing

The purified fish oil in QuattrO3 + PS is obtained using a unique cold and eco-friendly production process. Because WHC respects the environment, only oil from non-endangered species – anchovies, mackerel, herring and sardines – is used.

QuattrO3 + PS contains: 

• Exceptionally high concentration of omega-3 fish oil (over 90%) certified from sustainable fisheries and exclusively from non-endangered species

• 400 i.u. of vitamin D3 (or 10 mcg)

• Evening primrose oil

• Phosphatidylserine (soy-free, no allergy risk)

• No beef gelatine (suitable for pesco-vegetarians)

The product is also gluten and lactose-free and has no fish smell!

Easy to Take Flavoured Softgels 

QuattrO3+PS is supplied in packs of 60 tutti-frutti flavoured softgel capsules and is recommended for children aged 3 to 14 years. 

The recommended serving is 1 or 2 capsules per day, preferably taken at meal times. 

For children who cannot swallow capsules, cut open the softgel and squeeze the content onto cold foods such as yoghurts, pastas, rice or vegetables. A balanced mixture of rosemary and tocopherol extracts guarantees the freshness of each WHC supplement.

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 – the South Pacific coast – 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.
