Another thread prompted this one. I am wondering if we can absorb B12 from any plants, esp. nutritional yeast. I read somethings online that lead me to believe that we can't... that B12 is not bio-available to humans from plants.
Comments? Links to articles? Please educate me!
Edit: So then, if B12 is not bio-avail from plant sources, where does the B12 supplement come from, or even the B12 in soy milk, hemp milk, etc.?
