The trouble with this is, that some people cannot tolerate yeast, and some people lack the ability to process the yeast to produce B12. This is why the sublingual tablet or spray is superior. Especially in the methylcobalamin form as this doesn't have to *be* processed at all as it is already in the most bioavailable form for the body to use. dee

The best source I know of for vitamin B-12 is nutritional yeast. It is natural and it is accepted by the body. NO SYNTHETICS Thank You
