Yeast extract is a possible source of vitamin B12 for vegetarians and vegans, but should not be used as the only treatment for B12 deficiency. While it may offer some B12, it is not a substitute for supplements or injections. Absorption may be a concern for some people. It is essential to read labels for fortified B12 and sodium levels.
