Fish Oil
Fish oil is a concentrated source of the long-chain omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These essential fats are incorporated into cell membranes throughout the body and support cardiovascular health, brain function, inflammatory balance and healthy skin.
Because the body produces only limited amounts of EPA and DHA from plant-based omega-3s, oily fish and fish oil supplements are useful dietary sources.
EPA, DHA and Cell Function
EPA and DHA perform slightly different but complementary roles.
DHA is especially concentrated in the brain and retina, where it supports normal cell membrane structure, nerve signalling and visual function.
EPA is particularly involved in the production of signalling molecules that help regulate the body's inflammatory response.
Together, they contribute to healthy cell membranes across the cardiovascular, nervous and immune systems.
Heart and Brain Health
Omega-3 fatty acids are widely used to support heart and circulation because of their roles in normal triglyceride metabolism, blood vessel function and inflammatory balance.
DHA is also an important structural fat in the brain, making adequate omega-3 intake relevant throughout life for cognitive and nervous system health.
For people who eat little oily fish, fish oil can provide a convenient way to increase EPA and DHA intake.
Joints, Skin and Recovery
EPA and DHA are also useful in formulas aimed at joint comfort and healthy inflammatory balance.
Their incorporation into cell membranes influences the types of inflammatory signalling compounds the body produces, which can support comfortable movement and recovery from physical activity.
Omega-3s also contribute to the lipid barrier of the skin, helping support skin hydration and overall skin health.
Choosing a Quality Fish Oil
Fish oils are rich in delicate polyunsaturated fats that can oxidise if poorly handled.
Quality products should therefore be manufactured and stored carefully, with attention to freshness, purity and contaminant testing. Antioxidants such as vitamin E are often added to help protect the oil from oxidation.
The amount of EPA and DHA on the label is generally more useful than simply looking at the total quantity of fish oil.
Fish Oil for Pets
Fish oil is widely used in supplements for dogs and cats, providing EPA and DHA to support skin and coat condition, joint mobility, cardiovascular health, brain function and healthy ageing.
DHA is particularly relevant to cognitive and visual health, while EPA contributes to normal inflammatory balance. Fish oil is often paired with ingredients such as Greenshell™ Mussel, CoQ10 or antioxidants in broader pet-health formulas.
