A analysis published in Open Forum Infectious Diseases of three previous studies found that people who took 80 to 92 mg per day of zinc in the form of lozenges got better faster. By the fifth day, 70 percent of those taking zinc had recovered, compared with just 27 percent of those given a placebo.
A analysis published in The American Journal of Tropical Medicine and Hygiene reported similar reductions in duration but found conflicting evidence on whether zinc supplements had an effect on the severity of cold symptoms. Thomas and her colleagues were intrigued by some of the research on zinc and colds and wanted to see whether zinc supplementation had any beneficial effects on people with COVID which, like some colds, is caused by a coronavirus.
The researchers divided the participants into four groups. One group received standard treatment, one got high doses of vitamin C, one got high doses of zinc, and the fourth group got both supplements.
The amount of zinc you need daily is 11 mg for men and 8 mg for women. And the Institute of Medicine has set the tolerable upper intake level the maximum you should consume per day at 40 mg for adults. Zinc supplements and lozenges can also leave a metallic taste in your mouth, Thomas says. Nasal sprays containing zinc were popular cold remedies until the FDA warned that using them could cause you to lose your sense of smell. As a result, most if not all nasal sprays have either been reformulated without zinc or taken off the market.
For example, taking zinc with certain antibiotics such as quinolone or tetracycline can lower both the amount of the medication and the amount of zinc your body absorbs. This is a BETA experience. You may opt-out by clicking here. More From Forbes. Jul 31, , am EDT.

How Zinc Works While studied for many years, the exact mechanism of action by which zinc works to shorten the common cold is unknown. Zinc may also prevent cold viruses from attaching to cells in the lining of the nose and throat Evidence suggests that cold-shortening results may vary depending on the specific zinc formulation used and how it is administered.
