Metabolic vitamin B12 status on a mostly raw vegan diet with follow-up using tablets, nutritional yeast, or probiotic supplements
[www.ncbi.nlm.nih.gov]

"RESULTS:

49 subjects were tested. Most subjects (10th to 90th percentile) had followed this diet 23-49 months. 6 subjects had serum B12 concentrations <147 pmol/l (200 pg/ml). 37 subjects (76%) had serum B12 concentrations <221 pmol/l (300 pg/ml). 23 subjects (47%) had abnormal urinary MMA concentrations above or equal to 4.0 microg/mg creatinine. Sublingual cyanocobalamin and nutritional yeast, but not probiotic supplements, significantly reduced group mean MMA concentrations (tablet p < 0.01; yeast p < 0.05, probiotic > 0.20)."

"The World Health Organization (WHO) considers B-12 deficiency to be less than 200 pg. The percentages of B-12 deficiency tend to increase over time on a natural hygiene diet. Another study in Finland in 1995 that examined B-12 status of long-term 100% raw vegans found that 66% of the people had a B-12 lower than 200 pg. One study done in 2000 by Donaldson at Hallelujah Acres on primarily live food diet people, but with some B-12 supplementation via nutritional yeast, showed only about 15% of the people were less than 200, and none of them less than 160."

A potential game changer...

Nutritional Supplementation with Chlorella pyrenoidosa Lowers Serum Methylmalonic Acid in Vegans and Vegetarians with a Suspected Vitamin B12 Deficiency
[www.ncbi.nlm.nih.gov] (2015 Study)

"Seventeen vegan or vegetarian adults (26-57 years of age) with a known vitamin B12 deficiency, as evidenced by a baseline serum methylmalonic acid (MMA) level above 270?nmol/L at screening, but who otherwise appeared healthy were enrolled in the study. Each participant added 9?g of C. pyrenoidosa to their daily diet for 60?±?5 days and their serum MMA, vitamin B12, homocysteine (Hcy) levels as well as mean corpuscular volume (MCV), hemoglobin (Hgb), and hematocrit (Hct) were measured at 30 and 60 days from baseline. After 30 and 60 days, the serum MMA level fell significantly (P?<?.05) by an average ?34%. Fifteen of the 17 (88%) subjects showed at least a 10% drop in MMA. At the same time, Hcy trended downward and serum vitamin B12 trended upward, while MCV, Hgb, and Hct appeared unchanged. The results of this work suggest that the vitamin B12 in chlorella is bioavailable and such dietary supplementation is a natural way for vegetarians and vegans to get the vitamin B12 they need."

chlorella looks like a good idea.

isn't nooch pasteurized?

It is but personally I wouldn't be concerned about it. Calorie wise it would be lucky to make up 1% of my diet and it's a dense source of nutrients.

Here are a few links for more info...

[draxe.com]
[bragg.com]

The first link states "It’s even a great source of vitamin B6 and vitamin B12 and their benefits; however, because yeast cannot produce B12, if it is listed on the label, that means it has been fortified with it", but the second link states "Bragg uses natural Vitamin B12 in the form of Cobalamin".

some considerations regarding the chlorella

(jack norris updated his website with the study )

[jacknorrisrd.com]

Some caveats:

• Average serum MMA levels appeared to stabilize on this regimen at above recommended levels. B12 deficiency is generally defined as serum MMA levels above 270 nmol/L, the same standard used in this study by Merchant et al.

• The study was funded by Sun Chlorella Corporation of Japan and the lead author of the study is a paid consultant.

• A daily regimen of 45 Sun Chlorella A tablets (totaling 9 g) were used in this study. That amount of tablets would be quite costly. While it might require fewer than 45 tablets to achieve the same results, we can’t tell from this study.
