Does zinc help with slow recovery?

Yes — but only in one form. Zinc Sulfate is the one that was tested, and the others sold for this do not carry the same evidence.

Worth knowing before you buy. Zinc Picolinate is widely sold for slow recovery, but the trials behind that use tested zinc sulfate instead.
