Exclusive Antioxidant-Rich LifeSource Bits™

BLUE's exclusive LifeSource Bits are a precise blend of antioxidants, vitamins and minerals carefully selected by veterinarians and animal nutritionists that help support:

  • Immune system health
  • Life stage requirements
  • Healthy oxidative balance

And LifeSource Bits are cold-formed to help retain the potency of their ingredients. This means that we minimize the amount of heat that LifeSource Bits are exposed to during the manufacturing process. It’s the same concept as when you cook vegetables at high heat — the longer you do, the more heat-sensitive nutrients are lost.
