Hi. What can you do for low b12? And does low thyroid have anything to do with that? Thanks

B12. 1) taking B12 is the best treatment for low b12. However, pills may not work for some people who can't absorb it. In this case, you may need to take it by nasal spray, under the tongue, or by injection. 2) both hypothyroidism & inability to absorb B12 can be caused by auto-immunity, which means that a person's own immune system is attacking their own proteins and tissues.
Take B12/autoimmune. Treat low B12 with injection or pills (research shows pills work even for ppl w/ malabsorption). The link between thyroid and low B12 (might) be autoimmunity, as that may cause both thyroid disease and pernicious anemia causing low b12.
