It is also referred to as vitamin M, vitamin B9, vitamin Bc (or folacin), pteroyl-L-glutamic acid, and pteroyl-L-glutamate.Food supplement manufacturers often use the term folate for something different from \"pure\" folic acid: in chemistry, folate refers to the deprotonated ion, and folic acid to the neutral molecule\u2014which both coexist in water."@en .
