🍃🐾 Vet Guide 2025: Antioxidants in Senior Pet Foods — By Dr Duncan Houston

As small pets like rabbits and guinea pigs age, oxidative stress can impact their immune health, joints, digestion, and cognition. Including antioxidants in senior foods supports healthy aging. In this 2025 guide, I explain why they matter, where to find them, and how to integrate them safely into your pet’s diet. Let’s nourish their golden years! 😊

1️⃣ What Are Antioxidants & Why They Matter

• Antioxidants neutralize free radicals—unstable molecules that can damage cells, proteins, and DNA—especially during aging :contentReference[oaicite:3]{index=3}.
• In senior pets, oxidative stress increases due to metabolic wear, illness, or inflammation :contentReference[oaicite:4]{index=4}.
• Supporting antioxidant intake helps protect vital organs—heart, lungs, brain, gut, joints, and skin :contentReference[oaicite:5]{index=5}.

• 🌿 **Whole grains** like oats, barley, and yucca add antioxidant benefits plus fiber :contentReference[oaicite:7]{index=7}.
• 💊 **Vitamins E & C**, β-carotene, lutein—vital for immune, skin, eye, and cellular health :contentReference[oaicite:8]{index=8}.

6️⃣ Monitor Health & Adjust Over Time

• Track weight, coat quality, mobility, appetite, droppings, and activity monthly.
• Review bloodwork during vet visits to assess antioxidant-related organ health.
