About Seven Seas
Seven Seas has been one of the UK's most trusted supplement brands since 1935, with a heritage built on cod liver oil. Today the range brings together cod liver oil, omega-3 fish oil, joint care and multivitamins, drawing on decades of expertise in high-quality marine oils.
Cod liver oil is a natural source of the omega-3 fatty acids EPA and DHA, along with vitamins A and D. DHA contributes to the maintenance of normal brain function and normal vision, while EPA and DHA contribute to the normal function of the heart. Vitamin D supports the normal function of the immune system and helps maintain normal bones and muscle function, which is why it is often recommended through the winter months.
The Seven Seas range covers everyday and targeted needs: One-a-Day Cod Liver Oil capsules, pure Omega-3 fish oil, Joint Care with glucosamine, Simply Timeless multivitamins, and dedicated formulas for pregnancy and for children. Whether you prefer capsules or liquids, there is an option to suit your routine.

If you are pregnant, breastfeeding, taking medication or have a medical condition, speak to your pharmacist or GP before starting a new supplement.
Frequently asked questions
Is Seven Seas cod liver oil good for you?
Seven Seas cod liver oil is a food supplement that provides omega-3 (EPA and DHA) together with vitamins A and D. These nutrients support normal heart, brain, vision and immune function as part of a balanced diet. It is not a substitute for a varied diet, and if you take medication or have a health condition it is best to check with your pharmacist or GP first.
What are the benefits of Seven Seas Omega-3?
Omega-3 fish oil supplies the fatty acids EPA and DHA. DHA contributes to normal brain function and vision, and a daily intake of 250mg of EPA and DHA contributes to the normal function of the heart. Seven Seas offers omega-3 in both capsules and liquids so you can choose the format that suits you.
Is Seven Seas a good brand?
Seven Seas is one of the UK's longest-established supplement brands, first launched in 1935 and best known for its cod liver oil. Its products are widely available and made to UK food supplement standards. As with any supplement, choose the product that matches your needs and follow the recommended daily intake on the label.
Does Seven Seas Joint Care work?
Seven Seas Joint Care combines glucosamine with omega-3 and nutrients such as vitamin D, which contributes to the maintenance of normal bones and muscle function. Individual experiences of joint supplements vary and results are not guaranteed. If you have ongoing joint pain, speak to your pharmacist or GP for advice.
Are Seven Seas multivitamins good?
Seven Seas multivitamins, such as the Simply Timeless range, provide a blend of vitamins and minerals to help fill dietary gaps and support everyday health. They are designed to complement a balanced diet rather than replace it. Check the label to choose a formula suited to your age and needs.
Can I take Seven Seas cod liver oil when pregnant?
Standard cod liver oil is generally not recommended during pregnancy because it contains vitamin A (retinol), high levels of which can be harmful in pregnancy. Seven Seas makes supplements formulated specifically for pregnancy that exclude vitamin A. Always read the label and speak to your midwife, pharmacist or GP before taking any supplement while pregnant.
What is the difference between cod liver oil and omega-3 fish oil?
Both provide omega-3 (EPA and DHA). Cod liver oil comes from the liver of the cod and also naturally contains vitamins A and D, whereas omega-3 fish oil comes from the body of oily fish and is usually higher in EPA and DHA without the added vitamins A and D. Which suits you depends on whether you want those extra vitamins.
How do I take Seven Seas cod liver oil?
Follow the directions on the pack. Most Seven Seas cod liver oil capsules are taken as one a day with a meal, while liquids come with their own dosage guidance. Do not exceed the stated recommended daily intake, and keep out of the reach of children.
Can I give my dog Seven Seas cod liver oil?
Seven Seas cod liver oil is formulated and licensed for people, not pets. Dogs have different nutritional needs and different tolerances for vitamins A and D, so a human supplement is not suitable without veterinary advice. Speak to your vet, who can recommend a product and dose appropriate for your dog.
