If you’re comparing the best blueberries supplements for dogs, look beyond the headline ingredient. Quality signals include clear sourcing, lot testing, transparent dosing instructions, and a formula designed for dogs (not a human capsule repackaged). Avoid products that promise dramatic outcomes; responsible brands talk about support, not guarantees.
Also consider what the supplement is trying to do. A blueberry-only approach can be narrow. A more thoughtful option supports the larger network that influences aging, resilience, and recovery—because oxidative stress is rarely a single-ingredient problem. This is where multi-ingredient, veterinary-aware formulations can make more sense than chasing one “superfruit.”
