Rated 1 out of 5 by from Very odd smell and aftertaste. Trying to work with Puritan's Pride to determine if it was simple an off batch.

Rated 5 out of 5 by from glass container lessens bad smell. i bought another brand and when i opened it i did find this bad smell as well... reading up on it, it appears it is par for the course with this medication. However, if i put one whole bottle into a small glass jar - a half pint canning jar is perfect - the smell becomes more organic and natural and less toxic smelling. i think something in this medication interacts with the gelatin and the plastic containers.
