Perhaps if you don't like taking supplements, these mushrooms could be a new part of your nutrient coverage along with nutritional yeast (Red Star enhanced), chlorella and possibly with regular MMA testing. In spite of the discovery which I plan to use as more of a talking point against the claim that "plants have no b-12" which is now patently false. The B-12 issue for vegans hasn't changed that much. We still need a reliable source of b-12 whether through supplements or a combination of yeast/chlorella & nori/mushrooms & testing. "[jacknorrisrd.com] A 2012 study from the Watanabe group (1) was released today on PubMed. I have added the following to B12 in Tempeh, Seaweeds, Organic Produce, and Other Plant Foods. They found what they thought was active vitamin B12 in the following mushrooms (per 100 g of dry weight): 2.9 – 3.9 µg in black trumpet (Craterellus cornucopioides) 1.3 – 2.1 µg in golden chanterelle (Cantharellus cibarius) 1.3 µg in parasol (Macrolepiota procera) .3 – .4 µg in porcini (Boletus spp.) .2 µg in oyster (Pleurotus ostreatus) .1 µg in black morels (Morchella conica) The authors noted that 100 g of dry weight was the equivalent of about 1 kg of fresh mushrooms. They said that a moderate intake of black trumpet or golden chanterelle “may contribute slightly to the prevention of severe B12 deficiency in vegetarians.” They did not know why the mushrooms contained B12 and also did not test the mushrooms in humans to determine their ability to lower methylmalonic acid (MMA) levels. As always, I will add a word of caution that vegans should not rely on any plant food for vitamin B12 until a number of batches have consistently lowered MMA levels in humans."

Date: February 22, 2013 10:13AM I remember I've heard about natural vitamin D in mushrooms. If you flip them over and put them under the sun, they 'grow' vit D. But it is D2, which is not as good as D3. Re: mushrooms & B-12 Part 2

Date: February 23, 2013 05:36AM Fungi are more closely related to animals than plants:
[www.nytimes.com] Fungi digest plant foods to obtain nourishment like animals but do so externally. And, like animals, they need B12. Re: mushrooms & B-12 Part 2
