If you're taking zinc regularly, it's worth taking a small amount of copper as well — typically a 10:1 or 15:1 zinc-to-copper ratio.

Extracted claim

If taking zinc regularly, it is worth also taking a small amount of copper, typically at a 10:1 or 15:1 zinc-to-copper ratio.

Evidence-backed claim

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.

Extracted claim

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.

There's interesting data showing that zinc supplementation can improve sleep quality and reduce the time it takes to fall asleep. The mechanism isn't completely understood but may relate to zinc's role in melatonin metabolism.

Zinc supplementation can improve sleep quality and reduce the time it takes to fall asleep, possibly through zinc's role in melatonin metabolism.
