Product Overview

Crucial for a healthy nervous system, brain function and supports intestinal health 

PetTest Methyl B-12 is also called methylcobalamin. It is a vitamin not produced naturally in the body and must be obtained through specific foods and dietary supplements. Methyl B-12 is important for cell growth, the burning of fat and carbs, and the health of the nervous and brain systems, among other internal processes. Some dogs such as Border Collies, Australian Shepherds, Chinese Shar-Peis, and Beagles may be predisposed to absorbing vitamin B-12. Because Methyl B-12 goes through the body so quickly, each meal you feed your dog should contain this vitamin. 



  • Vitamin B-12 (as Methylcobalamin) 5000 mcg
  • Supports a Stronger Immune System 
  • Formation and Growth of Red Blood Cells
  • Helps with Having a Healthy Digestion
  • Helps to Prevent Pancreatic Disease 
  • Boosts the Health of the Nervous System

    Good and convenient

    I have been using this product for about 4 months now. Re-purchased this bottle so we will have it available on hand. It's a good product to help my dog's mobile strength. The one thing I wish could be better is the dropper. It's very hard to use for a consistent measurement all the time.

    I have been using B12 for most of my boy's 2 year journey, but I was so excited when y'all started carrying these drops! The fact that I can provide most of my boy's needs in one place is a great thing! Keeping my boy going at 10 years old like he's a puppy is the greatest thing ever. I highly recommend these drops!

    Methyl B12

    This is a great product! The smell is not too strong but strong enough to get my dogs noses going. This 4 oz bottle will last about 4 months... Bonus! If you have a diabetic dog or cat methyl B12 is so beneficial and AND REALLY HELPS WITH DIABETIC NEUROPATHY!

    Thank you PetTest!!!
