I've seen methyl. After some internet research I just started my kitty on a methyl b12 due to a possible pancreatic inefficiency. He has an abdominal mass and I haven't wanted to do anything too invasive due to his age. The methyl version gets absorbed better so it seems.
I may have to try pancreatic enzymes. Anybody familiar with this?
I've used them for my dogs in the past.... but they are fed raw so don't really need them. There is a homeopathic pancreas you could try. Elixirs.com sells it... All you need is one pill disolved in some liquid on a spoon and then one or two drops on kitty's gums.
