Vitamer Laboratories Cool Lemon Zinc Lozenges
Brand: Vitamer Laboratories · Form: LOZENGE [E0174] On Market
Our assessment
Our assessment: For immune support during cold season, zinc lozenges can be a helpful tool, but the data shows that consistent daily intake for prevention is not well-supported. The evidence shows that when taken within 24 hours of cold symptom onset, zinc lozenges may shorten the duration of a cold by about 33% [NIH ODS]. However, data on long-term, daily use for prevention is not available.
How it works
Think of zinc as a gatekeeper for your immune system. It helps your immune cells develop and function properly, and it can interfere with the replication of cold viruses in your throat [NIH ODS]. When you let a zinc lozenge dissolve slowly in your mouth, you are delivering the mineral directly to the area where the virus is trying to multiply.
Safety profile
FDA received 694 adverse event reports for zinc-containing products. Side effects reported with zinc lozenges include nausea (reported in 14 cases) and a bad taste or mouth irritation (reported in 9 cases) [FDA data]. High doses of zinc, above 40 mg per day for adults, can cause copper deficiency over time [NIH ODS]. Data not available for interactions with medications from this specific product.
Our recommendation
Our recommendation: Use Cool Lemon Zinc Lozenges only at the first sign of a cold and stop after 5–7 days. Do not exceed the dosage on the label. For most adults, 15–25 mg of zinc per day from lozenges is a common short-term dose [NIH ODS]. If you take antibiotics or diuretics, consult your doctor before using zinc supplements [NIH ODS].
