“There's interesting data showing that zinc supplementation can improve sleep quality and reduce the time it takes to fall asleep.”
Zinc supplementation can improve sleep quality and reduce the time it takes to fall asleep.

“During an acute illness — especially a respiratory illness — there's reasonable evidence that zinc lozenges, not capsules or tablets, can reduce the duration and severity of the common cold. The key is that the zinc needs to come into direct contact with the mucous membranes of the throat, which is why lozenges work better than swallowed supplements for this specific purpose.”
Zinc lozenges — not capsules or tablets — can reduce the duration and severity of the common cold during an acute respiratory illness, because zinc needs to come into direct contact with the mucous membranes of the throat.
None of the 10 published studies provided directly address the specific claim about zinc lozenges versus capsules/tablets for reducing common cold duration and severity. The available studies cover zi…
