Cold-EEZE Cold Remedy lozenges have been clinically proven to shorten the duration of the common cold by nearly half. The efficacy of our best selling lozenges is backed by double blind placebo controlled studies conducted at both the prestigious Cleveland Clinic and Dartmouth College.
Cold-EEZE is a homeopathic cold remedy made with a unique zinc gluconate formula. Perhaps you’ve heard about zinc gluconate in the health section of your newspaper or seen it on lists of common cold tips on the internet. Zinc is a micronutrient that’s essential to human health. In a well-formulated cold remedy, zinc gluconate facilitates the effective release of zinc ions which shorten the common cold.
Scientific theory suggests that once a person has been exposed to a cold virus, the virus attaches to receptors in the upper respiratory system and replicates. It’s further believed that zinc ions released into the throat compete for these same receptors and thereby prevent the cold virus from reproducing. The virus dies off faster and the cold ends sooner.
Zinc gluconate is the active ingredient in Cold-EEZE, the #1 pharmacist recommended zinc cold remedy and the best-selling zinc lozenge. Unlike some other zinc remedies, the Cold-EEZE unique zinc gluconate formula does not contain additives that might interfere with the release of zinc ions. Cold-EEZE zinc gluconate cold remedy is free of artificial colors or preservatives.
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.
