You can have your doctor write an RX for methylcobalamin
injections to be made up for you. Then you can specify the
mixing solution to avoid whatever is in the cyano form.

Or you can buy the patch that is online. (I don't know in reality if these work...since the company who makes them tends to spam them on the net, but if you are in a truly bad place, then
they are an option).

Most people who cannot absorb B12 from food, do absorb it
passively in the small intestine, if ENOUGH is given. You'd need 5mg a day on an empty stomach (food reduces absorption) to
accomplish that.
