Over at Jack's blog, he has updates on Vitamin D3, Vitamin B12 analogues, and DHA.
And after I posted yesterday (and thanks to everyone who "Liked" the post, here and on Facebook), I came across this from Lana Smithson:
Today at the Michael Franti concert .... I heard from a woman who said she had been a vegetarian but developed a severe B12 deficiency. She said she would prefer to be vegetarian and to raise her three children veg, but the deficiency really scared her, and her doctors (plural) told her she must eat meat (which she now does). I told her about Jack's website and she seemed interested to check it out.
