Zinc lozenges shorten colds

A new study suggests that higher doses of zinc lozenges in certain formulations may cut the length of colds by more than 40%.

There's still no cure for the common cold, but there may be a way to shorten its misery: A new study suggests that higher doses of zinc lozenges in certain formulations may cut the length of colds by more than 40%.

"Much of the variation in the published study findings can be explained by the daily dose of zinc administered in the zinc lozenges," said Hemila, who funded the research himself. "When focusing on those studies which have used large daily doses of zinc, there is strong evidence that zinc lozenges shorten the duration of colds."
