Different zinc lozenges have different amounts of the active form of zinc, and only the active form fights viruses.
Zinc lozenges might help with cold symptoms, but lab tests show zinc doesn't really fight cold viruses directly, so there's probably another reason they work.
Zinc salts tested in lab cells for cold viruses show they might not work well as a medicine because they could be more harmful than helpful.
