Naturally Enhances Your Pets Absorption and Utilization of B-12

For more information on your pet and the ability of B12 with Intrinsic Factor to make a difference in your pets health go to the following link: Epi4Dogs Foundation Inc.

Our PET Factor B-12 ™ formula provides Methylcobalamin B-12 in a base of Folic Acid and Intrinsic Factor for enhanced absorption of orally administered vitamin B-12.

B-12, Folic Acid and Intrinsic Factor work together. Folic Acid prepares B-12 for absorption, intrinsic factor attaches to the B-12 so it can be absorbed.

Intrinsic Factor is an enzyme like substance secreted by your pets stomach. Without the proper amount of Intrinsic Factor vitamin B-12 cannot be utilized and absorbed. This combination of ingredients from WonderLabs helps increase the overall bioavailability for your pet.

Exocrine pancreatic insufficiency (EPI) impairs an animal's ability to digest and absorb the nutrients available in food. Because of insufficient digestive enzymes created by the pancreas, food passes through the body basically undigested. Animal's will begin to lose weight and have loose, foul-smelling diarrhea. Animals with EPI eat voraciously because they are not able to gain nourishment from the food they do ingest.

Effective EPI ( Exocrine Pancreatic Insufficiency ) regimen.

    This product is amazing and with 2 large collies with EPI its a life safer. We would be lost with wonder drugs and their care and concern for the dogs they help save every day. Thank you shelley for your above and beyond customer service. Cassie and Tartan send their love and thanks as well.
