B12 for Cats (Methylcobalamin) is the neurologically active form of vitamin B12. Vitamin B12 is important for nerve cells, energy production and red blood cell production. A lack of vitamin B12 can contribute to a variety of problems, including cognitive dysfunction. Vitamin B12 is essential for red blood cell production, so too low a level of vitamin B12 in your cat's body may cause or contribute to anemia, therefore vitamin B12 supplements may help treat anemia.

Cats with IBD, pancreatitis and intestinal lymphoma have low levels of vitamin B12. Kitties with CKD benefit greatly from B12 supplementation in it's natural form (Methylcobalamin) as it reduces inflammation.

Methylcobalamin is more bioavailable than its synthetic counterpart, cyanocobalamin, and therefore more effective because it is absorbed more readily by the body.

    I have been giving this to my guy for a couple of months, along with Oxy-Cat and Vita-Cat. I am not sure if these products are beneficial from a metabolic standpoint. I can verify, however, that his coat is thicker and more luxurious.
    I had asked if there were research studies done for the various products in terms of efficacy and was told there were none. So pretty much going on anecdotal comments, reviews, and good faith.
    That said, I think 2 Crazy Cat Ladies ROCKS! Thank you Jae and Adrienne!!
