Vi har samlet de vanligste spørsmålene om Nordic Seal Omega 3 for å hjelpe deg med å ta et informert valg med trygghet. Informasjonen nedenfor er basert på etablert vitenskapelig veiledning fra offentlige helsemyndigheter, dvs. U.S. Food and Drug Administration (FDA) og European Food Safety Authority (EFSA), men er skrevet på en måte som overholder prinsippet om rimelig bruk og unngår opphavsrettslige bekymringer.

Omega-3 fatty acids are essential fats found in both plant and marine sources. There are four key types known for their health benefits:

  • ALA (alpha-linolenic acid) – found in plant-based foods like flaxseed, chia seeds, walnuts, and vegetable oils.
  • EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) – found mainly in fish oil and seal oil. These support heart, brain, and eye health.
  • DPA (docosapentaenoic acid) – a lesser-known but powerful omega-3 found in seal oil, shown to enhance the body’s ability to store and use EPA and DHA more efficiently

While the body can convert ALA into EPA and DHA, the conversion is very limited. That’s why marine omega-3s—especially those from seal oil, rich in DPA—are considered more effective for supporting cardiovascular, cognitive, and overall wellness.

  • Nordic Seal Omega 3 is made from seal oil derived from a responsibly managed harp seal population inhabiting the northern waters between Greenland and Jan Mayen.
  • For generations, seal harvesting has played a significant role in Norway’s maritime tradition and has contributed to the sustainable use of marine resources.
  • Modern seal harvesting is conducted under strict regulatory frameworks to ensure ecological balance. Catch limits are set in accordance with scientific guidance from the International Council for the Exploration of the Sea (ICES).
  • In practice, the actual number of seals harvested in recent years has remained well below the approved quotas.

  • Yes. The raw materials are of the highest quality and are processed in accordance with pharmaceutical-grade standards, including Good Manufacturing Practice (GMP) guidelines
  • It is guaranteed that each product is formulated to be pure, safe, and suitable for human health.
  • All ingredient and health-related claims are supported by scientific evidence and are aligned with assessments approved by the European Food Safety Authority (EFSA), making them verifiable and compliant with EU regulations.

While both seal oil and fish oil are excellent sources of long-chain omega-3 fatty acids like EPA and DHA, seal oil stands out due to its unique composition and biological origin.

  • Contains DPA – a rare omega-3: Seal oil naturally includes docosapentaenoic acid (DPA), an important but often overlooked omega-3 that plays a complementary role to EPA and DHA. Fish oil typically contains only trace amounts of DPA, while seal oil offers it in significantly higher concentrations.
  • Better absorption – mammal to mammal: Because seals are mammals, their fat structure is more similar to humans. This allows omega-3s in seal oil to be more easily processed and absorbed during digestion compared to fish oil.
  • Unique triglyceride structure: The molecular binding of omega-3s in seal oil differs from that in fish oil. This structural variation is believed to support more efficient uptake of fatty acids into the bloodstream.
  • Naturally adapted for cold: Seals thrive in Arctic conditions. Their oil remains fluid in low temperatures, thanks to a higher ratio of unsaturated fatty acids, which may offer added benefits for cellular function and cardiovascular health.
  • A more complete omega-3 profile: With EPA, DHA, and DPA all naturally present, seal oil provides a broader spectrum of omega-3s that may support a wider range of health functions—especially for the heart, immune system, and inflammatory balance.

Today, seals are primarily harvested using rifles. Anyone participating in seal hunting must complete a training course and pass the required examinations set by the Norwegian Directorate of Fisheries.

  • Hunters are required to act with the highest level of consideration and use methods that prevent unnecessary suffering for the animals.
  • Only shooters who have passed a special shooting test are allowed to shoot seals during the hunt. This test must be retaken before each hunting season. The test must be taken using the same weapon and ammunition type that will be used during the actual hunt.
  • It is prohibited to hunt: Seal species other than harp seal (greenland seal) and hooded seal. Adult female hooded seals and adult harp seals in birthing areas. Seals that are in the water. The full regulations can be found in the Norwegian legislation: “Regulation on the Practice of Seal Hunting”A veterinarian is present on all hunting expeditions to monitor and report on the harvesting process.

     

  • Seal oil comes from marine mammals, which naturally sit high on the food chain. Because of this, their fat may accumulate certain fat-soluble substances like PCBs or dioxins.
  • To ensure safety and quality, the oil undergoes a multi-stage purification process. This advanced refining removes unwanted contaminants as well as odor and taste, resulting in a clean, neutral oil that is safe for human consumption.

  • Yes. After purification, the oil is tested and confirmed to comply with all safety limits set by Norwegian food authorities (Mattilsynet).
  • The refining process is conducted at a certified food-grade facility in Norway that specializes in marine oils.

  • To some extent, yes. While purification is essential for removing toxins, it may also reduce some of the oil’s natural antioxidants, pigments, and vitamins.

Omega-3 fatty acids—especially EPA, DHA, and DPA—are vital nutrients that support multiple systems in the body. Researchers have been studying their effects for decades, and while not all questions are fully answered, there is strong evidence supporting several key health areas:

  • Heart Health: Eating oily fish rich in omega-3s has been consistently associated with a lower risk of heart disease. EPA and DHA, in particular, help reduce triglyceride levels, support healthy blood vessels, and may reduce inflammation linked to cardiovascular issues. The American Heart Association (AHA) recommends consuming fish or seafood 1–2 times per week as part of a heart-healthy diet. For individuals with existing heart conditions, about 1 gram of EPA+DHA per day is advised, though supplements may be considered under medical supervision
  • Vision and Eye Health: Omega-3s play a role in eye development and maintenance. People who consume more omega-3s from food may have a lower risk of age-related macular degeneration (AMD)—a leading cause of vision loss. However, omega-3 supplements have not been shown to slow the progression of AMD once it develops. Regarding dry eye disease, results are mixed. Some trials report symptom improvement with EPA and DHA supplementation, while others—including large-scale studies—show no significant effect compared to placebo.
  • Pregnancy and Infant Development: During pregnancy and breastfeeding, getting enough omega-3s—especially DHA—is important for the baby’s brain and eye development. Breast milk naturally contains DHA, and most infant formulas are now fortified with it.
  • Cognitive Function and Aging: Some studies have linked higher intake of omega-3s with a reduced risk of Alzheimer's disease, dementia, and cognitive decline. While results are not yet conclusive, maintaining a diet rich in marine omega-3s may be beneficial for long-term brain health..
  • Rheumatoid Arthritis: For individuals with rheumatoid arthritis (RA), omega-3 supplements may offer mild relief. They can reduce reliance on anti-inflammatory medication when taken alongside standard RA treatments. However, omega-3s should not replace prescribed therapies..
  • Other Conditions Under Study: Researchers are also investigating the potential role of omega-3s in ADHD and childhood behavioral health, allergic conditions, cystic fibrosis. Although early results are promising in some areas, more high-quality studies are needed to draw firm conclusions.

In summary, Omega-3 fatty acids are linked to numerous health benefits, particularly for the heart, brain, eyes, and immune function. While foods rich in EPA, DHA, and DPA (such as seal oil or fatty fish) remain the best sources, food supplements may be useful in specific cases under professional guidance.

Always consult your healthcare provider before beginning any supplement routine.

  • A deficiency in omega-3 fatty acids may lead to various symptoms, including rough, dry, or scaly skin, as well as redness, swelling, or itchy rashes.
  • In the long term, low levels of omega-3s have also been linked to increased risk of cardiovascular issues, poor cognitive function, and mood disturbances such as anxiety or depression.
  • Ensuring an adequate intake of EPA, DHA, and DPA is essential for maintaining optimal heart, brain, and skin health.

For most people, omega-3 supplements are well tolerated and considered safe when used as directed. Health authorities in the U.S. suggest limiting daily intake of EPA and DHA from supplements to no more than 5 grams, unless otherwise advised by a healthcare provider.

  • Yes, especially at high doses. Omega-3 supplements may affect how certain medications work—particularly blood thinners such as warfarin or other anticoagulants. If you are taking prescription medication or managing a chronic condition, it is important to speak with your doctor or pharmacist before adding omega-3 supplements to your routine

  • Yes. A comprehensive meta-analysis of 40 clinical trials with over 135,000 participants found that omega-3 supplementation (EPA and DHA) was associated with:
    • 13% reduction in the risk of heart attacks
    • 10% reduction in coronary heart disease
    • 35% reduction in fatal heart attacks
    • 9% reduction in deaths from heart disease

  • Some “neutral” findings occur when participants already have high baseline levels of omega-3, often due to diets rich in seafood or prior use of omega-3 supplements. In such cases, adding more may not lead to significant improvements.
  • For example, in the OMEMI study (elderly participants in Norway), most already had optimal omega-3 levels, so the effect of further supplementation was limited.

  • Not necessarily. While the REDUCE-IT study (using high-dose ethyl-EPA) showed impressive results, larger meta-analyses have not found a statistically significant difference between EPA monotherapy and combined EPA+DHA therapies.
  • This suggests that both EPA and DHA may contribute to cardiovascular protection, depending on dose and individual factors.

  • If possible, yes. Testing the Omega-3 Index (percentage of EPA+DHA in red blood cells) helps tailor supplementation for best results. Many researchers agree that ignoring baseline omega-3 levels may lead to misleading study outcomes.
  • An Omega-3 Index above 8% is typically considered optimal for cardiovascular protection.

  • Studies indicate a dose-response relationship – meaning higher doses generally provide stronger effects, as long as they stay within safe limits.
  • However, individuals with already high omega-3 levels may only need low maintenance doses, while those with low baseline levels might require higher intakes.

  • If you’ve been maintaining healthy omega-3 levels through supplementation, suddenly stopping may lower your Omega-3 Index, potentially reducing cardiovascular benefits.
  • That’s why consistent, long-term use is important, especially for people who don’t eat much fatty fish or are at higher cardiovascular risk.

  • Choose products made from high-quality marine sources, ideally those that are purified and third-party tested for safety and potency.
  • While both EPA-only and EPA+DHA formulations have shown cardiovascular benefits, some marine oils—such as seal oil—naturally contain a third omega-3 fatty acid called DPA (docosapentaenoic acid). DPA has been suggested to play a complementary role in supporting heart and vascular health, though research on DPA is still emerging.
  • What’s most important is to choose a product that:
    • Clearly states dosage and origin
    • Follows national health and safety regulations
    • Aligns with your personal health needs and dietary habits
