High-dose zinc supplements found to speed recovery from colds and flu by 300%

A new study conducted at the University of Helsinki and published in Open Forum Infectious Diseases found that simple, low-cost zinc supplementation greatly speeds recovery from colds and influenza infections.

The study, authored by Harri Hemilä, James T. Fitzgerald, Edward J. Petrus and Ananda Prasad, pursued a meta-analysis tracking of the recovery progress in human patients given either zinc acetate lozenges or placebo. They found a 300% faster recovery time among those who took zinc lozenges containing 80 – 92 mg/day.
