What Are LifeSource® Bits?

LifeSource Bits are the small, dark kibbles mixed in with our BLUE dog and cat dry foods. They contain a precise blend of vitamins, minerals, and antioxidants selected by holistic veterinarians and animal nutritionists. To ensure that dogs and cats get the full benefit of these vital nutrients, LifeSource Bits are “cold-formed” to help preserve their potency.

The Health Benefits of LifeSource Bits

LifeSource Bits include ingredients that help benefit dogs and cats in three ways.

Help dogs and cats maintain a healthy oxidative balance

Virtually every day, our dogs and cats are exposed to environmental factors that can negatively impact their oxidative balance. And if their biological systems are not able to rebalance this oxidative stress, it can lead to cellular destruction and other serious health issues.

As antioxidants can play an important role in reducing oxidative stress, an increasing number of veterinarians are recognizing their importance in helping pets maintain a healthy oxidative balance. This is the science that led our nutritionists to formulate BLUE's LifeSource Bits with ingredients that are rich in antioxidants. These include:



  • Kelp
  • Vitamin E
  • Vitamin C
  • Beta Carotene
  • Vitamin A
  • Blueberries
  • Barley Grass

Help support a pet's immune system.

LifeSource Bits contain ingredients that help support a pet’s immune system:

  • Alfalfa
  • Flaxseed
  • Parsley
  • Vitamin C
  • Cranberries

Help support a pet’s specific life stage requirements.

LifeSource Bits also contain ingredients that can help protect a pet’s changing needs from youth through his mature years. These include:

  • Omega 3 and Omega 6 Fatty Acids for healthy skin and coat
  • Yucca Schidigera Extract for joint health
  • Taurine for healthy eyes and heart
  • L-Lysine for growth and development
  • Vitamin D for healthy bones and tissue
  • Vitamin B12 for growth
  • L-Carnitine for endurance and fat metabolism
“Cold-Formed” Process

Recognized as a breakthrough in canine and feline health because of the multiple benefits they provide, LifeSource Bits are also a manufacturing breakthrough because they are “cold-formed” to preserve nutritional potency of the ingredients. BLUE is the ONLY brand of pet food to use this “cold-formed” process.

When you compare dog foods or compare cat foods, you will see that this “cold-formed” process is an important difference between BLUE and other brands that add antioxidants and vitamins. Other manufacturers process their foods with heat as high as 350°. High heat can destroy the potency of many vitamins, minerals, antioxidants and important enzymes. It’s the same concept as when you cook vegetables at high heat—the longer you do, the more heat-sensitive nutrients are lost.

LifeSource Bits are manufactured separately at a lower temperature from the rest of our kibble to preserve greater potency of the vitamins and antioxidants. This way, your pet can gain as many benefits as possible from these valuable nutrients.

Water-soluble vitamins are the most sensitive to heat. Nutritionists estimate that these vitamins can lose a minimum of 30% of their potency when exposed to high temperatures, while some, like vitamin C, can lose up to 75% of their potency.

BLUE LifeSource Bits contain eight water-soluble vitamins which benefit most from the “cold-formed” process:

  • Vitamin B1 (Thiamin)
  • Vitamin B2 (Riboflavin)
  • Vitamin B12
  • Vitamin C
  • Folic Acid B9
  • Niacin B3
  • Biotin B7
  • Pantothenic Acid B5
