Zinc acetate Lozenges Could Hasten Cold ReliefZinc acetate lozenges may actually cause people to recover faster from a common cold by three-fold.

According to a review of three randomized controlled trials, zinc acetate lozenges may actually increase the rate of healing from the common cold by around three fold. On the fifth day, 70% of the zinc lozenge patients had recovered in comparison with 27% of the placebo patients.

The effect of zinc acetate lozenges was regardless of factors such as age, sex, race, hypersensitive reactions, smoking, or cold illness severity. For this reason the three-fold increase in recovery from colds may be widely applicable. Whilst some zinc lozenges have a disagreeable taste, the zinc acetate lozenges used in these three randomized trials don't have them.

Common Cold And Zinc Acetate Lozenges

The dose of zinc in the three trials was between 80 to 92 mg/day. Such doses are significantly greater than the advocated daily zinc intake in the US, which is 11 mg/day for men and 8n g/day for women. Nevertheless, in different studies which were unrelated to colds, zinc has been administered in doses of 100 mg to 150 mg/day to sufferers for months with few adverse results. Furthermore, 150 mg/day zinc is a regular therapy for Wilson’s disorder that requires remedy for the patient's lifetime. As a consequence, it seems extremely unlikely that 80-92 mg/day of zinc for one to two weeks, starting very quickly after the onset of the initial symptoms of a cold, could lead to long-term adverse events results. Not one of the three analyzed zinc lozenge reviews determined adverse effects of zinc.

Despite the fact that there may be powerful evidence that thoroughly formulated zinc acetate lozenges can increase recovery from colds by three- fold, many zinc lozenges in the marketplace show up to have either too low doses of zinc or they have other ingredients that bind zinc ions, similar to citric acid. Hence, the findings of this meta-analysis should no longer be directly extrapolated to the variety of zinc lozenges on the present market.

Even though the lead author, Dr. Harri Hemilä from the University of Helsinki, Finland, says that the premiere formula of zinc lozenges and the good frequency of their administration should be additionally investigated, he also instructs patients with the common cold to know personally whether zinc lozenges are good for them. He says, given the strong evidence of efficacy and the low risk of adverse effects, common cold patients may already be encouraged to try zinc acetate lozenges not exceeding 100 mg of elemental zinc per day for treating their colds.
