How to Choose the Right Fish Oil for Pets
Learn what EPA/DHA levels, sourcing, and purity standards matter when selecting omega-3 supplements for dogs and cats.
Fish oil is one of the most popular supplements for dogs and cats. But not all fish oils are created equal. When sourcing or selecting a product, there are three key factors to consider: EPA/DHA concentration, sourcing, and purity.
EPA and DHA Levels
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the active omega-3 fatty acids responsible for most health benefits. Look for products with clearly stated EPA and DHA levels rather than just total fish oil content.
Sourcing Matters
Wild-caught small fish such as anchovies, sardines, and mackerel are preferred because they are lower on the food chain and accumulate fewer heavy metals. Reputable suppliers should provide traceability from catch to bottle.
Purity Testing
Third-party testing for heavy metals, PCBs, and oxidation levels is essential. Always request a Certificate of Analysis (COA) before placing bulk orders.
Conclusion
Choosing the right fish oil means balancing potency, purity, and sustainability. At PawLifeWellness, all our fish oil products are wild-caught, heavy-metal tested, and backed by full COAs.
