Collection: Fatty Acids

Omega oils for different routines

Compare omega-3, -6, -7 and -9 products, from fish oils and cod liver oils to plant-based and multi-omega formulas.

Explore omega and fatty-acid supplements in capsules, liquids, oils and chewable formats. The current range includes fish oil, cod liver oil, krill oil, sea-buckthorn oil, hemp seed oil and multi-oil formulas supplying different combinations of omega-3, omega-6, omega-7 and omega-9 fatty acids. Compare the oil source, fatty-acid profile, amount in the recommended daily serving, added vitamins and storage instructions.

Omega-3, omega-6, omega-7 and omega-9 are different groups

The word omega does not describe one ingredient. Omega-3 products may provide EPA and DHA from marine sources or alpha-linolenic acid from plant oils. Omega-6, omega-7 and omega-9 fatty acids occur in different oils and combinations. Some products are highly focused, while berry, seed and multi-oil formulas can contain several omega groups.

Choose according to the specific fatty acids and amounts stated on the label rather than the number of omega groups listed in the product name. For products focused on omega-9, browse the omega-9 collection.

Fish oil, cod liver oil, krill oil and plant oils

Fish oils commonly provide EPA and DHA. Cod liver oil can also contain naturally occurring or added vitamins A and D, so it should not be compared with a plain fish-oil concentrate by total oil volume alone. Krill oil supplies marine fatty acids in a different oil matrix and may include naturally occurring astaxanthin or choline, depending on the product.

Plant-based products in the assortment include sea-buckthorn and hemp oils as well as berry-seed combinations. Their fatty-acid profiles differ from marine oils. A vegan oil should therefore be compared by its declared fatty acids and intended product role rather than treated as a direct equivalent of every fish-oil formula.

Compare EPA and DHA in the recommended daily serving

For marine omega-3 products, check the separately declared amounts of EPA and DHA in the full recommended daily serving. The total fish-oil amount is not the same as the amount of omega-3, and the total omega-3 amount is not always the same as the combined EPA and DHA figure.

Products also differ in serving size and concentration. One formula may use a small number of concentrated capsules, while another uses a liquid teaspoon or several capsules. Compare the actual daily amounts and follow the labelled serving. Any authorised health claim depends on the qualifying fatty acid amount and its conditions of use, not simply the presence of fish oil.

Check added vitamins and combination ingredients

Cod liver oils and several omega products contain vitamins A, D or E. Other formulas combine fatty acids with magnesium, vitamin C, botanical extracts or ingredients intended for a broader specialist formula. These additions can change suitability and create overlap with multivitamins or separate vitamin products.

Review the full ingredient list and daily amounts before combining an omega product with vitamin supplements. A product with additional nutrients is not automatically better; it is a different formula that should fit the rest of the routine.

Capsules, liquids and children's formats

Capsules are easy to portion and carry. Liquids can provide a concentrated serving without several capsules but require accurate measuring and may have refrigeration instructions after opening. Flavoured liquids and enteric-coated capsules address taste and convenience in different ways. Chewable fish-shaped or gel products are available for children when the individual product is labelled for the relevant age.

For child-specific age and serving comparisons, use the children's vitamins collection. Do not reduce an adult serving or assume that every oil is suitable for a child.

Source, quality information and storage

Product pages may identify fish species, fishing area, traceability, oxidation testing or certifications such as MSC or Friend of the Sea. These details are product-specific. Check what the certification covers and avoid assuming that the same sourcing applies to every product from a brand or category.

Storage also varies. Some liquids should be refrigerated after opening, while capsules may be stored at room temperature under the stated conditions. Protect oils from heat and light according to the pack and use them within the indicated period.

Allergens, medicines and suitability

Fish, krill and other marine products are not suitable for everyone with seafood allergies. Capsule shells can contain fish gelatine, bovine gelatine or plant materials. Plant oils can have different allergen and dietary-suitability information.

Some products carry warnings related to blood coagulation or medicines. Follow the individual label and ask a healthcare professional or pharmacist when medication, surgery, pregnancy, breastfeeding or a health condition affects suitability.

Frequently asked questions about fatty-acid supplements

Is fish-oil amount the same as omega-3 amount?

No. The total oil, total omega-3 and the individual EPA and DHA amounts can all be different. Compare the figures in the recommended daily serving.

Is cod liver oil the same as fish oil?

Both are marine oils, but cod liver oil often also supplies vitamins A and D. Check the full composition and do not treat the products as automatically interchangeable.

Can vegans use fatty-acid supplements?

Some plant oils are vegan, but they have different fatty-acid profiles from fish or krill oil. Check the finished product's suitability and declared fatty acids.

Do all omega oils need refrigeration?

No. Storage depends on the product and packaging. Follow the instructions on the individual pack, especially after opening a liquid oil.
