Product Overview
Give Your Pet the Gift of Vitality with PetTest Methyl B-12!
Want to help your beloved pet thrive from the inside out? Our PetTest Methyl B-12 supplement is a powerful way to support their overall health, especially their nervous system, brain function, and intestinal well-being!
Also known as methylcobalamin, Vitamin B-12 is absolutely essential – but your pet's body can't produce it naturally. That's why providing this vital nutrient through their diet is so important! Methyl B-12 plays a key role in so many internal processes, from healthy cell growth and energy metabolism (like burning fat and carbs) to keeping their brain and nervous system functioning optimally.
Because this incredible vitamin moves through the body fairly quickly, we recommend including it with each meal to ensure your dog is consistently getting the benefits they need. (Did you know some breeds, like Border Collies and Beagles, can be especially predisposed to needing extra B-12 support?!)
Why PetTest Methyl B-12 is a Must-Have:
- Powerful Support: Each serving delivers 5000 mcg of Vitamin B-12 (as Methylcobalamin).
- Boosts Immune Health: Helps strengthen their natural defenses.
- Healthy Blood: Supports the formation and growth of vital red blood cells.
- Happy Tummy: Contributes to a healthy digestion system.
- Pancreatic Wellness: Helps prevent pancreatic disease.
- Sharp Mind & Nerves: Gives their nervous system a healthy boost!
Invest in your pet's health and happiness with PetTest Methyl B-12 – because a healthy pet is a happy pet!
