Reader Question: 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.
