Why Seven Seas Matters for Daily Health

Omega-3 intake is often low in Western diets, yet DHA and EPA play vital roles in heart rhythm, inflammatory balance and brain function. Seven Seas supplements offer a convenient way to support these areas, especially for people who eat little oily fish. Cod liver oil, in particular, provides vitamins A and D alongside omega-3, supporting immunity, bone maintenance and skin integrity — useful during winter or low-sun periods.

Many Seven Seas products complement categories such as omega-3, vitamins, vitamin D and immunity supplements.

Expert Insight & Scientific Context

Nutrition specialists consider omega-3 one of the most impactful supplements for long-term health. Research shows DHA contributes to brain development and cognitive maintenance, while EPA plays a role in inflammation pathways. Meanwhile, vitamin D deficiency remains common in the UK, especially during winter, making cod liver oil a practical dual-benefit source of vitamin D and omega-3.

Joint formulas combining glucosamine, chondroitin and omega-3 have supportive evidence for comfort and mobility, especially in older adults or individuals with high activity levels.
