Introduction — first two whole paragraphs

Zinc, an essential mineral, is naturally present in some foods, added to others, and available as a dietary supplement. Zinc is also found in some cold lozenges, over-the-counter drugs sold as cold remedies, and some denture adhesive creams.

Zinc is involved in many aspects of cellular metabolism. It is required for the catalytic activity of hundreds of enzymes, and it plays a role in enhancing immune function, protein and DNA synthesis, wound healing, and cell signaling and division [1-4]. Zinc also supports healthy growth and development during pregnancy, infancy, childhood, and adolescence and is involved in the sense of taste [2,3,5].

Food — whole detailed opening paragraph

The richest food sources of zinc include meat and fish, and other seafood [3]. Oysters contain more zinc per serving than any other food, but beef contributes 20% of zinc intakes from food in the United States because it is commonly consumed [7]. Eggs and dairy products also contain zinc [3]. Beans, nuts, and whole grains contain zinc, but the bioavailability of zinc from these foods is lower than that from animal foods because these foods contain phytates.

Dietary supplements — whole detailed opening paragraph

Zinc is available in supplements that only contain zinc, supplements that contain zinc in combination with other ingredients, and in many multivitamin/mineral products [13]. Supplements can contain any of a variety of forms of zinc, including zinc sulfate, zinc acetate, and zinc gluconate [14]. The Supplement Facts panel on a dietary supplement label declares the amount of elemental zinc in the product, not the weight of the entire zinc-containing compound.

The common cold — two whole consecutive paragraphs reporting the 2024 review and its certainty

More recently, the authors of a 2024 Cochrane Review concluded that zinc may reduce symptom duration by about 2 days in people who already have a cold, but zinc appears to make little to no difference in preventing colds [61]. These conclusions were based on the results of 34 trials in a total of 8,526 participants, and most of the trials administered zinc in the form of lozenges. The authors also concluded that it is unclear whether zinc affects the severity of cold symptoms.

They noted that all of these conclusions were based on low to very low certainty of evidence.

Health Risks from Excessive Zinc — whole detailed opening paragraph

High zinc intakes can cause nausea, dizziness, headaches, gastric distress, vomiting, and loss of appetite [2,3]. If used for weeks, doses of 50 mg zinc or more—typically from supplements or excessive use of denture adhesive creams that contain zinc—can interfere with copper absorption (which can cause low copper status), reduce immune function, and lower HDL cholesterol levels [1-3,101].

Interactions with Medications — whole detailed introductory paragraph and whole antibiotics paragraph

Zinc has the potential to interact with certain medications. In addition, several types of medications might adversely affect zinc levels. A few examples are provided below. Individuals who are taking these and other medications on a regular basis should discuss their zinc status with their health care providers.

Both quinolone antibiotics (such as Cipro) and tetracycline antibiotics (such as Achromycin and Sumycin) might interact with zinc in the gastrointestinal tract, which could inhibit the absorption of both zinc and the antibiotic if they are taken at the same time [103,104]. Taking the antibiotic at least 2 hours before or 4 to 6 hours after the zinc supplement minimizes this interaction [103].
