Can You Take Marshmallow Root and Vitamin B12 Together?

May affect absorption

The short answer

Marshmallow Root contains high amounts of mucilage that may coat the GI tract and reduce or delay absorption of other supplements taken at the same time.

How to arrange timing

Take Marshmallow Root at least 2 hours apart from other supplements to avoid absorption interference.
