“Dr. Patrick's practical takeaway is to favor a well-formulated, non-aerosol mineral sunscreen, especially zinc oxide, while avoiding inhalation and recognizing that mineral and chemical filters have different evidence and uncertainties.”

“Of particular relevance in viral disease is the movement of zinc, an essential nutrient that inhibits the action of RNA-dependent RNA polymerase — the enzyme critical for the reproduction of RNA viruses such as SARS-CoV-2, the virus responsible for COVID-19.”

“The authors of the meta-analysis drew on data from seven placebo-controlled zinc lozenge trials involving 575 children and adults. The doses used in the studies ranged from 80 to 207 milligrams per day, using zinc gluconate (four trials) and zinc acetate (three trials).”

“Uptake of zinc requires an ionophore, a molecule that can transport ions across a lipid membrane. Quercetin, a bioactive compound present in a variety of fruits and vegetables, especially apples and onions, is a zinc ionophore.”

“For example, heavy metal concentrations are elevated in breast milk. Cadmium, a toxic metal that impairs the metabolism of nutrients essential to infant development, including selenium, zinc, copper, and magnesium, poses a particular threat because it is also a carcinogen.”

“However, marginal deficiency, which is asymptomatic and dangerous over long periods of time, is likely very common. Children, older adults, and people with altered gastrointestinal function are particularly susceptible to zinc deficiency.”

“However, they concluded that zinc (as lozenges or syrup) reduced the duration and symptoms of a cold in otherwise healthy people when given at the onset of symptoms. When given for at least five months, zinc also reduced the incidence of colds by 37 percent.”

“These studies, along with others that include hydrolyzed collagen in combination with vitamins and minerals, such as vitamins C and E, biotin, and zinc, suggest that the consumption of oral hydrolyzed collagen may be effective at improving skin aging.”

“The formula and the person both matter. Vitamin K can interact with warfarin, and iron, preformed vitamin A, vitamin B6, iodine, selenium, zinc, and other nutrients can become excessive when products are stacked.”
