Findings to review with care

Side effects reported for the ingredient alone are separated from findings involving another supplement or medication.

Side effects reported when this ingredient was used alone

Symptoms or adverse events reported in studies of this ingredient without another active ingredient.

Non-serious adverse events (nausea, mouth/nasal irritation)1 papers
Non-serious adverse events such as nausea and mouth/nasal irritation were higher with zinc compared to placebo (RR 1.41, NNH=7, moderate-certainty).Human studies · Meta-analysis

Positive combinations studied

Positive combination findings are separated by how the study compared the groups. This is not a recommendation to combine them.

Positive findings when used together

The combination had a positive result, but the contribution of each ingredient could not be separated.
