Manganese is taken up by the liver and other tissues, but the mechanism of this process is not well understood [1,2]. The human body contains about 10 to 20 mg manganese, ... Other forms include manganese gluconate, manganese picolinate, manganese sulfate, manganese citrate, and manganese chloride. ...
