    No more upset tummy!

    My cat Tuxedo hasn’t thrown up since I started him on the vitamin B12! He seems to be a much happier kitty. Thank you so much!

    Great health!

    My senior cat’s coat stopped having dandruff after taking B12 supplement.Also, her insatiable appetite seemed to become more regular.

    Got this for my 20 year old to help with everything but especially for her eating. She likes the taste, I add it to her food. Time will tell!

    Save Alice's life

    Alice has pancreatitis, which means when she has a flair up her food goes in one end and creates diarrhea for her. With having this issue she does not get her vitamins. So her last vet visit showed she was anemic and needed B12. Since the vet only had it in pill form and never heard of it in liquid form, I was concerned, because Alice has a little mouth and as we all know pills are hard to get into some cats mouth. I came home and went on Facebook and what should appear in one of Jackson Galaxy post was a liquid B12. I asked the vet about it and she checked it out and said she was not familiar but to go ahead and try it. Before the B12 Alice was lethargic and slept a lot, since then she is back to being more lively. So, Jackson Galaxy thank you for making this in liquid form, it probably helped save my Baby Cats(Alice) life.

    This has been working wonders for my cat who is 15 years old and with a thyroid issue. Since we have received the supplement which has been a couple of months now we have seen remarkable improvement in his health, more active and just been overall happy. My other 15 year old cat is also receiving the supplement as well (healthy). Very pleased with his progress, and will continue with this supplement for the rest of his life.
