You know how some "normal" ranges in blood tests still find us hurting?! I'm wondering what the normal range for Vit B12 for a menstruating woman? I've got really low ferritin (12) any my B12 was 472. I'm working on ferritin restoration, but wonder about my Bs. I've heard some with Lyme benefit from Vit B shots, and I'm soooo tired all the time, just wondering if that could be a culprit (along with the fact that I have Lyme, low iron, low Vit D and dealing with detoxing and herxing.)

Anything under 500 for B12 is too low, and what is optimal for a "healthy person" (which is what these normal ranges are based on) may not be enough for someone with Lyme or any other chronic illness.

The normal range in the US is ridiculously low compared to other countries... For example, in Japan, 500 is the low cutoff for B12. In the US, it is something like 250...waaaay too low.

Many of us feel better with B12 supplementation - make sure though that it is methyl-B12 or hydroxy-B12 because those are forms the body can use directly without having to convert.

The Cyano-B12 has to be converted, and the cyano- part then has to be detoxed...which adds more stress to already stressed out detox pathways for those of us with Lyme...

Thanks. Is b12 something that will increase with supplementation over time?
