The Power of Omega-3: Fuel for a Stronger Immune System

By MAIREAD O’KEEFFE New Leaf Health Store

Our immune system is like a quiet guardian—always on duty, scanning for threats, and stepping in when bacteria, viruses, or other invaders try to take hold. To keep it sharp, what we put on our plates matters. One nutrient that stands out for immune resilience is omega-3 fatty acids. Omega-3s are essential fats the body cannot make on its own, which means we must source them from food or supplements. There are three main types: EPA and DHA (found in oily fish like salmon, sardines, and mackerel) and ALA (from plants such as flax,

chia, and walnuts). Together, they provide wide-ranging benefits— from calming chronic inflammation to supporting brain and heart health—but their role in immunity is especially compelling. Research shows that omega-3s help regulate immune responses by dampening unnecessary inflammation, improving the activity of phagocytes (the body’s frontline defenders), and supporting the balance of T-cells and B-cells, which fine-tune our defenses. They also nurture a healthier gut microbiome—a cornerstone of long-term immunity.

So how do you get enough? Aim for two to three servings of oily fish a week, or reach for high-

quality omega-3 supplements. Not all oils are created equal, so look for brands that emphasize purity and sustainability. One standout is Wild Atlantic, an Irish brand renowned for its premium marinesourced omega oils. Their focus on quality and freshness ensures the beneficial compounds remain potent, giving your immune system the best support nature can offer. Whether sprinkled through your diet or taken daily in supplement form, omega-3s are a small habit with a big payoff. By making them part of your routine, you’re not just feeding your body— you’re strengthening your natural defenses for the seasons ahead.
