Vegan Sources of Vitamin B12 (Cobalamin)
A slight deficiency of vitamin B-12 can lead to anemia, fatigue, mania, and depression, while a long term deficiency can potentially cause permanent damage to the brain and central nervous system. Vitamin B-12, or Cobalamin, is naturally found solely in animal foods and thus vegans have to supplement their diets with fortified foods or supplements.
A wide array of cereals now exist with the percent daily value (DV) of vitamin B12 added in. Vegans can eat the cereal with soy, rice, or almond milk.

How much Vitamin B12 is in Brewers Yeast?
Brewers Yeast is a rich source of nutrients, typically used for making beer, but can also be used to make breads and other consumables. There are conflicting reports on how much vitamin B12 brewers yeast provides. The University of Maryland Medical Center states that it provides no B-12. However, the nutrition facts from Now Foods lists a whopping 3 micrograms (50% DV) of vitamin B12 in two tablespoons of brewers yeast. This is way more B12 than what you can get from Marmite or other yeast extracts. So, as ever with nutrition facts, it is best to buy a product where you can consult the label for specific B12 content. One should also be cautious on counting on the yeast as a sole source for vitamin B12.
