Anyway, it's ubiquitous nowadays to see short paragraphs such as this:
>>> "....If you're over age 50, consume vitamin B-12 in its crystalline form, which is found in fortified foods or supplements...." <<<<
Remember... this is ALL Americans, no matter what their health conditions or genetics, no matter what their Vitamin B12 status is.
I never buy the cyanocobalamin; I only purchase the methyl versions of B-12, usually just the methylcobalamin.
I'm frankly quite unsure what year the guidelines changed and that they had press releases and consequently many articles in the press about it. Perhaps it's archived away somewhere in Nexus Lexus but I'm not a subscriber.
BTW, mtDNA haplogroups 'V' and 'U' are dominant amoungst the Sa'ami people. My mother is 'V' and my dad's mother is 'U5a'...so.
I have yDNA R1b1b2 which indicates that I'm a Dane who wound up in Ireland...long ago, maybe as a Viking? (One of my dad's sisters had red hair)
