It seems like every month a new study comes out advocating drinking.

On an unrelated note...

Does anyone here know if parasites commonly cause B12 deficiency?

I read one testimonial, but don't know if the patient's interpretation is correct. The claim is made it's a common problem.

An another site, the question is asked by a parent if parasites should be dealt with first before B12 supplementation.

I know supplementation works; I just wonder if people will get quicker results without parasites.
