<< The question is, does taking spirulina interfere with B-12 absorption from
animal sources? To be more specific, do the B-12 analogues occupy the same
receptors in the body and hence reduce the amount of useful B-12 that can
be absorbed? (sort of the way trans fatty acids take the place of healthy cis
fatty acids and then don't do the same job). >>
that is the speculation. i haven't found out for sure, yet.
