What Are Cod Liver Oil Capsules and How Can They Help You?

 

Valupak Vitamins cod liver oil capsules offer a simple, affordable way to top up your intake of omega-3 fatty acids alongside the fat-soluble vitamins A and D — all in one easy-to-swallow 400mg capsule. At just £1.19 for a pack of 30, they're one of the most cost-effective supplements you'll find. Whether you're looking to support your joints, maintain healthy bones, or give your immune system a little extra help through the winter months, cod liver oil has been a trusted staple in British households for generations. You can browse the full range of vitamins and supplements available at Cured Pharmacy if you'd like to explore other options alongside this product.

Cod liver oil is derived from the livers of Atlantic cod and has been used in the UK as a nutritional supplement for well over a century. The NHS recognises that vitamin D, found naturally in cod liver oil, plays an important role in keeping bones and muscles healthy — particularly during autumn and winter when sunlight exposure is limited. Vitamin A, also present in this supplement, contributes to normal vision, immune function, and the maintenance of healthy skin.

 

How Do Cod Liver Oil Capsules Work in the Body?

 

Once swallowed, the gelatin capsule dissolves in the stomach, releasing the oil. Because omega-3 fatty acids, vitamin A, and vitamin D are all fat-soluble, they are best absorbed when taken alongside a meal containing some dietary fat. Here's a quick overview of how each key component works:

  • EPA (eicosapentaenoic acid): An omega-3 fatty acid that supports cardiovascular health and helps maintain normal triglyceride levels in the blood.
  • DHA (docosahexaenoic acid): Contributes to normal brain function and maintenance of normal vision.
  • Vitamin A: Supports immune function, normal vision, and healthy skin cell turnover.
  • Vitamin D: Essential for calcium absorption, bone mineralisation, and normal muscle function — particularly relevant in the UK where dietary sources are limited.

Together, these nutrients work synergistically to support several body systems at once, which is why cod liver oil remains one of the most widely recommended general supplements in the UK.

 

Who Is Suitable for Valupak Cod Liver Oil 400mg Capsules?

 

These capsules are suitable for most healthy adults who want to supplement their diet with omega-3 fatty acids and vitamins A and D. They're particularly useful if your diet is low in oily fish — the NHS recommends eating at least one portion of oily fish per week, but many people in the UK fall short of this. The following groups may find cod liver oil capsules especially beneficial:

  • Adults with low dietary intake of oily fish (e.g. salmon, mackerel, sardines)
  • People looking to support joint comfort and flexibility
  • Those wanting to maintain bone health, particularly older adults
  • Individuals seeking immune support during autumn and winter months

These capsules are not suitable for pregnant women or those trying to conceive, as the vitamin A content may be harmful to a developing baby at higher doses. They are also unsuitable for anyone with a known allergy to fish or fish products.

How Should You Store Valupak Cod Liver Oil Capsules?

Always keep them out of the reach and sight of children. Do not use after the expiry date printed on the pack. If you're also managing other aspects of your health, you might find it helpful to explore our skin care range, as vitamins A and D also play a role in maintaining healthy skin.

What Is Valupak Cod Liver Oil 400mg and What Is It Used For?

 

Valupak Vitamins Cod Liver Oil 400mg Capsules are an over-the-counter nutritional supplement containing cod liver oil as the active ingredient. Each capsule provides omega-3 fatty acids — specifically EPA and DHA — along with naturally occurring vitamins A and D. This supplement is used to help maintain adequate intake of these nutrients when dietary sources are insufficient. The NHS advises that everyone in the UK, particularly during autumn and winter, should consider a vitamin D supplement, and cod liver oil is one way to achieve this alongside omega-3 support.

These capsules are commonly taken to support joint comfort, bone health, cardiovascular health, and normal immune function. They are not a medicine and are not intended to treat, cure, or prevent any disease. If you have a diagnosed condition such as osteoporosis or cardiovascular disease, always follow the advice of your GP or specialist rather than relying solely on supplements.

 

What Do You Need to Know Before Using Valupak Cod Liver Oil Capsules?

 

Before taking these capsules, read the following contraindications and warnings carefully:

  • Do not take if you are pregnant or trying to conceive — vitamin A in cod liver oil can harm a developing baby at high doses
  • Do not take if you have a known allergy to fish or fish products
  • Do not exceed the stated dose — excessive vitamin A intake over time can cause toxicity
  • Consult your GP or pharmacist if you have a blood clotting disorder or liver disease
  • Not intended for children unless specifically directed by a healthcare professional
  • If you are already taking a multivitamin containing vitamins A or D, check total daily intake to avoid exceeding safe upper limits

The following drug interactions are known or theoretically possible:

  • Warfarin and other anticoagulants: Omega-3 fatty acids may enhance the blood-thinning effect, increasing bleeding risk — seek medical advice before use
  • Retinoid medications (e.g. isotretinoin, acitretin): Combined use may lead to vitamin A toxicity — avoid concurrent use
  • Orlistat (weight loss medicine): May reduce absorption of fat-soluble vitamins including A and D

 

How Should You Use Valupak Cod Liver Oil 400mg Capsules?

 

Follow these steps to use this supplement correctly:

  1. Check the expiry date on the pack before use
  2. Take one capsule daily unless otherwise directed by a healthcare professional
  3. Swallow the capsule whole with a full glass of water — do not chew or crush
  4. Take with or immediately after a meal to improve absorption and reduce the risk of a fishy aftertaste
  5. Store the remaining capsules in a cool, dry place below 25°C
Indication Age Group Dose Frequency
General omega-3 & vitamin supplementation Adults (18+) 1 capsule (400mg) Once daily
Not recommended Pregnant women N/A Avoid — vitamin A risk
Not recommended without medical advice Children under 18 Seek GP guidance As directed

 

What Are the Possible Side Effects of Valupak Cod Liver Oil Capsules?

 

Most people tolerate cod liver oil capsules without any problems. Side effects, when they do occur, are usually mild and temporary. If you experience anything that concerns you, stop taking the capsules and speak to your pharmacist or GP.

Common side effects:

  • Fishy aftertaste or fishy-smelling breath
  • Mild nausea, particularly if taken on an empty stomach
  • Burping or belching
  • Loose stools or mild diarrhoea

Less common side effects:

  • Heartburn or indigestion
  • Mild stomach cramps
  • Skin reactions in those with fish allergies (seek urgent medical attention if this occurs)

Signs of vitamin A toxicity from prolonged excessive intake may include headache, nausea, dizziness, and blurred vision. Do not exceed the recommended daily dose. If you are concerned about any side effects, contact your pharmacist or GP immediately. You can also explore our hair care range, as vitamin A and D deficiency can sometimes affect hair health.

 

How Should You Store Valupak Cod Liver Oil 400mg Capsules?

 

  • Store below 25°C in a cool, dry place

  • Keep the container tightly closed when not in use
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the pack

How do cod liver oil capsules work in the body?

Once swallowed, the capsule dissolves in the stomach and releases the oil, which is then absorbed through the gut wall. The omega-3 fatty acids EPA and DHA are incorporated into cell membranes throughout the body, supporting cardiovascular, joint, and brain health. Vitamins A and D are stored in the liver and released as needed to support immune function, bone mineralisation, and vision.

How do I take Valupak Cod Liver Oil 400mg Capsules step by step?

Take one capsule daily with a full glass of water, swallowing it whole — do not chew or crush. It's best taken with or immediately after a meal to improve absorption of the fat-soluble vitamins and reduce the chance of a fishy aftertaste. Continue daily as part of your regular supplement routine.

What is the best time of day to take cod liver oil capsules?

There is no strict rule, but taking your capsule with your largest meal of the day — typically lunch or dinner — tends to give the best results. Dietary fat in the meal helps your body absorb the fat-soluble vitamins A and D more efficiently. Taking it at the same time each day also helps you build a consistent habit.

What are the side effects of taking cod liver oil capsules?

The most commonly reported side effects are a fishy aftertaste, mild burping, or slight nausea — especially if taken on an empty stomach. These effects are generally harmless and can usually be avoided by taking the capsule with food. Serious side effects are rare but may include allergic reactions in people with fish allergies; stop use and seek medical advice if this occurs.

How do I manage the fishy aftertaste from cod liver oil capsules?

The simplest way to reduce a fishy aftertaste is to take your capsule with or immediately after a meal rather than on an empty stomach. Storing the capsules in the fridge (if the label permits) can also help, as cold oil tends to be digested more slowly, reducing burping. Drinking a full glass of water with the capsule also helps.

Who should not take cod liver oil capsules?

Cod liver oil capsules are not suitable for pregnant women or those trying to conceive, because the vitamin A content can be harmful to a developing baby at high doses — the NHS specifically advises avoiding supplements containing vitamin A in pregnancy. They are also unsuitable for anyone with a fish or shellfish allergy. People taking anticoagulant medicines such as warfarin should seek medical advice before use.

Can I take cod liver oil capsules if I am on warfarin?

Omega-3 fatty acids can enhance the anticoagulant effect of warfarin, which may increase your risk of bleeding. If you are taking warfarin or any other blood-thinning medication, you must speak to your GP or pharmacist before starting cod liver oil capsules. Your INR may need to be monitored more closely if you do begin taking them.

Are Valupak Cod Liver Oil Capsules suitable for vegetarians or vegans?

No — these capsules are not suitable for vegetarians or vegans. The capsule shell is made from gelatin, which is derived from animal sources, and the oil itself comes from fish liver. If you follow a plant-based diet and want an omega-3 supplement, look for algae-based DHA/EPA alternatives, which are available in our vegan collection.

What happens if I miss a dose of cod liver oil capsules?

If you forget to take your capsule on a given day, simply take it as soon as you remember — unless it is almost time for your next dose, in which case skip the missed one and carry on as normal. Do not take two capsules at once to make up for a missed dose. Missing the occasional dose is unlikely to cause any harm, as these nutrients accumulate gradually in the body.

How long can I take cod liver oil capsules for?

Cod liver oil capsules can generally be taken long-term as part of a balanced lifestyle, and many people take them year-round. However, because each capsule contains vitamin A, it is important not to exceed the recommended daily dose over extended periods, as excessive vitamin A accumulates in the liver and can become toxic. If you are taking other supplements containing vitamin A, check your total daily intake.

What are the alternatives to cod liver oil capsules?

If cod liver oil is not suitable for you — for example, if you are pregnant — alternatives include omega-3 fish body oil capsules (which do not contain vitamin A), algae-based omega-3 supplements for vegans, or separate vitamin D3 supplements. The NHS recommends a daily 10 micrograms vitamin D supplement for everyone in the UK during autumn and winter, regardless of diet.

Do cod liver oil capsules help with joint pain?

Omega-3 fatty acids found in cod liver oil have been studied for their role in supporting joint health, and some research suggests they may help reduce stiffness and discomfort associated with conditions such as rheumatoid arthritis. However, these capsules are a food supplement and are not licensed to treat any medical condition. If you have persistent joint pain, speak to your GP for a proper assessment.

What are the latest studies on cod liver oil and health?

Research continues to explore the role of omega-3 fatty acids in cardiovascular health, cognitive function, and inflammation. Studies have suggested that regular omega-3 intake may support heart health by helping to maintain normal triglyceride levels, though the evidence for specific disease prevention remains mixed. The NHS and NICE continue to review emerging evidence, so it is worth checking NHS.uk for the most up-to-date guidance.

Is 400mg of cod liver oil enough, or do I need a higher dose?

For general supplementation in healthy adults, a 400mg cod liver oil capsule taken daily provides a useful contribution to omega-3 and vitamin intake alongside a balanced diet. Higher-dose omega-3 products exist and may be recommended by a doctor for specific conditions such as hypertriglyceridaemia, but these are typically prescription-only. For everyday dietary support, 400mg is a widely used and appropriate dose.

How Should You Use Valupak Cod Liver Oil 400mg Capsules?

Using these capsules correctly is straightforward, but a few simple steps will help you get the most from them. Always read the label before starting and check the expiry date on the pack.

What Is the Correct Dose of Valupak Cod Liver Oil 400mg Capsules?

The standard recommended dose for adults is one 400mg capsule per day. Do not take more than the stated dose, as these capsules contain vitamin A, which can accumulate in the body and become harmful if taken in excess over a prolonged period.

When Is the Best Time to Use Valupak Cod Liver Oil 400mg Capsules?

There is no single "correct" time, but taking your capsule with your main meal of the day — whether that's lunch or dinner — is generally recommended. Vitamins A and D are fat-soluble, meaning they are absorbed more efficiently when consumed alongside dietary fat. Taking the capsule at the same time each day also makes it easier to remember and helps you maintain a consistent routine.

How Long Can You Use Valupak Cod Liver Oil 400mg Capsules For?

These capsules can be taken daily on an ongoing basis as part of a healthy, balanced lifestyle. Many people take cod liver oil year-round, particularly in the UK where dietary oily fish intake and sunlight exposure are often insufficient to maintain optimal vitamin D levels. That said, because the capsules contain vitamin A, it is important not to exceed the recommended dose over the long term. If you are also taking other supplements or a multivitamin containing vitamins A or D, check your combined daily intake to ensure you remain within safe limits. If you have any concerns about long-term use, speak to your pharmacist.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Valupak Cod Liver Oil 400mg Capsules?

Most people who take cod liver oil capsules experience no side effects at all. When they do occur, they tend to be mild and related to the digestive system. The most frequently reported issue is a fishy aftertaste or fishy-smelling breath after taking the capsule, which is harmless but can be unpleasant.

  • Fishy aftertaste or breath
  • Burping or belching
  • Mild nausea, particularly if taken on an empty stomach
  • Loose stools or mild diarrhoea

What Are the Less Common Side Effects of Valupak Cod Liver Oil Capsules?

A smaller number of people may experience slightly more noticeable digestive discomfort, especially when first starting the supplement or if the dose is taken without food. These effects usually settle within a few days as your body adjusts.

  • Heartburn or acid reflux
  • Mild stomach cramps or bloating
  • Indigestion
  • Headache (uncommon)

What Are the Serious Side Effects of Valupak Cod Liver Oil Capsules?

Serious side effects are rare when the product is used as directed. However, there are two important risks to be aware of. First, if you have a fish allergy, taking cod liver oil capsules could trigger an allergic reaction — symptoms may include skin rash, itching, swelling of the face or throat, or difficulty breathing. This requires immediate medical attention. Second, taking more than the recommended dose over a prolonged period can lead to vitamin A toxicity (hypervitaminosis A), with symptoms including persistent headache, nausea, dizziness, blurred vision, and dry or peeling skin. This is why it is essential never to exceed the stated dose.

What Should You Do If You Experience Side Effects?

If you notice mild digestive side effects such as a fishy aftertaste or nausea, try taking the capsule with a larger meal or at a different time of day. This often resolves the issue without needing to stop the supplement. If you experience signs of an allergic reaction — such as swelling, hives, or breathing difficulties — stop taking the capsules immediately and call 999 or go to your nearest A&E. For any other persistent or worrying symptoms, stop use and contact your GP or pharmacist for advice.

Can Valupak Cod Liver Oil Capsules Interact With Other Medicines?

Yes, there are some clinically relevant interactions to be aware of. Omega-3 fatty acids can enhance the effect of anticoagulant medicines such as warfarin, potentially increasing the risk of bleeding — always inform your GP or pharmacist if you are taking blood-thinning medication. Taking cod liver oil alongside retinoid medicines (such as isotretinoin or acitretin, used for skin conditions) may increase the risk of vitamin A toxicity and should be avoided. Orlistat, a weight loss medicine, can reduce the absorption of fat-soluble vitamins including A and D, so timing of doses may need to be adjusted. Always tell your pharmacist about all medicines and supplements you are taking before starting cod liver oil capsules.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
