🐾 Why Omega-3s Matter for Pets
Omega-3 fatty acids are essential for your pet’s skin, coat, brain, heart, immune system, and joint health. While dogs and cats cannot produce omega-3s on their own, adding natural sources to their diet is vital. But not all omega-3s are equal. EPA and DHA (from marine sources) are more bioavailable and impactful than ALA (from plant sources), especially for cats.
Did You Know? Deficiency in omega-3 can lead to dull coat, dry skin, allergies, arthritis, and cognitive decline in aging pets.
🧬 Types of Omega-3 Fatty Acids
Omega-3 Type | Source | Best For |
---|---|---|
ALA (Alpha-Linolenic Acid) | Flaxseeds, chia seeds | Mild anti-inflammatory, not well converted by pets |
EPA (Eicosapentaenoic Acid) | Fish oil, krill oil, sardines | Skin, joints, heart |
DHA (Docosahexaenoic Acid) | Salmon, anchovies, algae oil | Brain, eye, cognitive health |
