According to your guidance, the word "folate" will be banned from "supplement fact" labels -- only the term "folic acid" will be allowed. To ban folate from the label is an underhanded way of banning folate from the bottle.
The FDA must not implement this change. There is no rational basis for limiting supplement makers to the synthetic form only.
The agency claims this is because folate can only be found in "conventional" (whole or minimally processed) foods, while fortified foods and dietary supplements can only contain "folic acid." This is nonsense. Folinic acid (5-FTHF), calcium methylfolate, and various other tetrahydrofolates -- all of them dietary folates, not synthetic folic acids -- are commonly found in dietary supplements, and for a good reason.
