Good day all. I was diagnosed with a B-12 Deficiency on February 23 with a level of 153 P/mol. I was immediately started on monthly injections (I am in Canada) and daily sublingual 1,000 MCG tablets. I take two tablets daily and have had 5 shots since that time. On April 10 my levels were at 515 and on June 16 they showed 983. I have not been tested for any absorption issues. Would this rise in levels based on only 5 shots (no loading) over a course of only 4 months likely rule out an absorption problem?
