Taking zinc acetate lozenges when you have a cold can help you get better faster, cutting down how long you're sick by about 2 to 3 days.
Zinc lozenges don't help reduce how long colds last or how bad they feel, whether you catch a cold naturally or in a study where they give you a cold virus.
When adults with cold symptoms take zinc gluconate lozenges, their colds might get better faster, but this only worked in a special test setting and not with real-world colds or different zinc types.
Taking zinc supplements like gluconate or acetate doesn't help reduce how long a cold lasts or how bad the symptoms are, based on a study with 281 adults who had colds.
Taking special high-strength zinc lozenges when you have a cold can help you get better about three days faster.
