Nutrition & Diet Vitamin B12 - Recommended Dosage ?

[Val]

Speaking about brands,- i'm using MRM brand (it's being manufactured in the US). Has anyone ever been taking it? (It's Methylcobalamin, 2000 mcg).

I would also like to point out that the “standard” B12 test (serum B12 level test, the one I have also taken) can bring inaccurate results and that the other tests, Holo-TC, Homocysteine and MMA, are preferable to get a precise answer.

And yes, if you have never had your B12 level checked after some years as a vegan or vegetarian, I suggest to do it.
