How the Cold-EEZE® Cold Shortening formulation works

Cold-EEZE® products can shorten the duration of the common cold, when taken at the first sign of symptoms and used as directed.

Zinc gluconate is the active ingredient in all Cold-EEZE® products that can shorten the duration of the common cold. The zinc gluconate found in the unique Cold-EEZE formula, releases zinc ions in the upper respiratory system. Although the precise mechanism is unknown, scientific studies suggest that the zinc ions inhibit the cold virus from replicating, shortening the duration of the common cold.

Clinically Tested to Shorten Colds by 42%

A clinical study found the Cold-EEZE zinc lozenge formula reduces the duration of the common cold by 42%, when taken at the first sign of symptoms and used as directed.

A double-blind placebo-controlled study was conducted at the Cleveland Clinic and published in a peer review journal.

Although the precise mechanism by which zinc ions interfere with the cold virus has not been scientifically established, the Cleveland Clinic study demonstrated that Cold-EEZE® lozenges significantly reduced the duration of the common cold.
