B12 test

[Awil]

I believe I am b12 deficient from my symptoms and a low normal level of 238. I've been supplementing 5mg of b12 for the last month and seen great improvement. My GP has requested my b12 be tested. Should I stop supplementing before the bloods? I only have 6 days until the test.

Thanks.

If the oral supplements are working then the B12 is getting into your system. Once in there it hangs around for a long time. You would need several months for B12 levels in the blood to drop.

Tell the GP that you've been taking the supplements and that they seem to be working.
