Not sure if this helps or if you are interested but I recently heard about a new oral prescription alternative to the injections called Eligen B12. I recently read that it works even if you don't have intrinsic factor (so even if you don't have normal gut absorption). Apparently it came out a month or two ago.

This Eligen product is mentioned on our B12 thread on the PN forum...

It has been in the pipeline for several years.

I see two disappointing things concerning it.

1) it does not have the methylcobalamin in it...which is superior to cyano form. We now know that 10-30 % of adults cannot methylate properly and convert cyano to its active form in the body. So this cyano product will not work for them.
This is called the MTHFR mutation.

2) And it is RX only and therefore expensive. All other forms of B12 are OTC.

As a dosage form improvement, it does look promising. But why pay so much when Methylcobalamin is easily absorbed on an empty stomach (even when intrinsic factor is missing), for pennies a day?
