Keeping your pet healthy starts with a strong immune system. It’s their natural defense against germs, allergens, and toxins. Supporting that system begins with what you feed them.
Feeding a nutrient-dense diet rich in vitamins, minerals, and superfoods helps boost immune function. Add in targeted supplements like omega fatty acids and you’re giving your pet the daily support they need to stay resilient and recover quickly.
Your pet’s immune system protects them from bacteria, viruses, and parasites. It produces white blood cells and antibodies that neutralize threats before they cause harm.
However, nutritional gaps or deficiencies can weaken these defenses, increasing the risk of infections, allergies, or slower recovery.
These signs may indicate a weakened immune system:
- Fatigue or low energy
- Frequent skin or ear infections
- Slow healing from cuts
- Digestive issues
- Food sensitivities
Immune health depends on a broad spectrum of micronutrients including antioxidants, beta glucans, and essential vitamins–that stimulate immune cells and promote proper immune system function.
Vitamins A, C, D & E
These fat-soluble and water-soluble vitamins support immune system function by:
- Supporting calcium absorption and immune cell regulation (D)
- Building protective barriers (A)
- Neutralizing free radicals (C & E)
- Reducing inflammation (D)
Bonus: Beta carotene (from carrots or sweet potatoes) helps convert to Vitamin A naturally and supports eye health in dogs.
Zinc & Selenium
Vital for white blood cell production and healing, zinc and selenium are critical trace minerals that help regulate immune response and hormone balance. Deficiencies in these minerals may impair your pet’s ability to fight off infection or recover from illness.
Omega-3 Fatty Acids
Found in fish oil, omega-3s reduce inflammation and strengthen immunity. They also support joints, the heart, and skin, especially for aging pets.
Probiotics (in food)
Gut health plays a big role in immune strength. Probiotics help maintain a healthy gut, which is closely tied to overall immune strength. Our recipes include ingredients to support digestion and nutrient absorption–especially helpful during times of stress or recovery.
Look for these antioxidant-rich, immune-boosting foods in your pet’s daily meals:
- Leafy greens like spinach or kale
- Orange vegetables (carrots, sweet potatoes)
- Blueberries and cranberries
- Shiitake or maitake mushrooms
- Whole grains and fiber
- Lean proteins
- Healthy fats like fish oil or coconut oil
Health Extension recipes include nearly 30 superfoods, plus a slow-cooked preparation method that preserves nutrients and enhances digestibility, without fillers or artificial additives.
Even with a great diet, some pets need extra immune support during stress, travel, or seasonal shifts. Health Extension offers targeted solutions made with naturally sourced ingredients that work in harmony with your pet’s daily nutrition.
