This has been a life saver for my cat!
From UndisclosedComments about Rx B12My cat has stomach issues and lost a bunch of weight. My vet suggested probiotics and Vitamin B12. At one point I was giving him an injection once a week which was really hard on us both. With this liquid, I squirt it on his wet food once a day and he has improved dramatically! The stopper is pre-measured to the correct dose and it smells like bacon. He gobbles it up! Would definitely recommend. Very convenient to order and I would recommend! -

Can you tell me what is the absorption rate of cyanocobalamin from this product for dogs? I already purchased as my dog has chronic renal failure and the vet feels that he needs B12 but she wanted him to get shots. I found your product and she feels that it won't be as absorb as much vs giving him shots. I'm on a budget and was just wondering if it has the same absorption rate as prescription injections. Thanks! By the way, my dog likes the flavor!?

Cyanocobalamin is better absorbed as an injection and may not have dependable absorption when given orally. Please defer to your veterinarian’s recommendation to ensure the best therapy for your dog.
