B12 absorption is a typical problem for CDers. CD tends to attack the area of the bowel where B12 is absorbed and either limit the amount absorbed or surgery removes it entirely. The body stores some, so that it can take months to years before you need to start having supplements, but because you can not absorb it in the bowel, taking it in pill form is not effective. There is a nasal spray, but from what I have been told, it is not very pleasant and patients tend to be non-compliant. There is also a sub lingual form, but for severe deficiencies I don't think you can absorb enough that way. You will find that a lot of us have to take B12 shots. Some take them monthly, others bi-weekly. I'm a bi-weekly person. Also, some people notice a difference, others don't. I only notice, if I am late getting my shot. B12 has to do with energy, but also lack of B12 can cause nerve damage. It is not something you want to mess with. Once the damage is done, it is not reversible. When I am due for my shot, I get little nerve tingling on my scalp and I know I have waited too long between shots. Like insulin, it is something you can give yourself, or someone can learn to give to you. It makes it a little easier than having to drive to the doctors office every 2 weeks just for a 2 second shot. You do have to get a prescription for the B12 and the syringes, but once you learn what to do it is much easier.
