Two chemicals, pyrithione and hinokitiol, can fight certain viruses by needing zinc helpers to work, and they do this by raising zinc levels inside cells—a new way to stop these viruses.

These two chemicals help zinc quickly get inside cells and go to specific spots like mitochondria. This temporary zinc boost is what makes them fight certain viruses.

Two chemicals stop a virus from cutting an important protein in cells, which might help prevent the virus from making copies of itself.

Two special chemicals can stop certain viruses from growing in lab tests by messing up how the viruses build their parts, which might help fight these types of viruses.

Taking very high doses of vitamin C right when you start feeling a cold won't make the cold shorter or less severe for healthy adults compared to taking normal amounts.

A chemical called PDTC messes with how two viruses build their parts, but in different ways: for one virus, it stops a key cutting step inside the virus, and for the other, it blocks a different...

A chemical called PDTC helps move zinc into cells, and this zinc helps fight off certain viruses.

A chemical called PDTC stops two types of viruses from copying themselves by messing up their genetic material, which was shown in lab experiments.

Different types of zinc supplements work about the same in male rats eating a diet high in phytic acid, because they grew similarly and had similar zinc levels in their bodies.

When male rats eat food low in zinc and also get phytic acid added, it makes their zinc levels drop even more compared to rats that don't get the extra phytic acid.

When male rats eat a diet high in phytic acid (which makes it hard for their bodies to absorb zinc), giving them a special type of zinc called EDTA disodium zinc helps their bodies use the zinc...

Blood zinc levels are the best way to check if you have enough zinc, but they can change throughout the day or if you're sick.

Foods high in phytate, like beans, can block zinc absorption, but eating protein helps your body take in more zinc.

When added to foods like tortillas, zinc oxide and zinc sulfate are absorbed about the same.

Some studies show zinc gluconate supplements are absorbed better than another common form, but other studies find no real difference in zinc levels in people's blood. The results are mixed.

Taking zinc glycinate pills for 6 weeks raises zinc levels in the blood more than other zinc types or fake pills in women.

A honey-based herbal syrup called Honey Zufa was given to people with COVID-19, and it didn't cause any major problems or changes in their health tests over two weeks, showing it's safe to use.

When people took Honey Zufa syrup along with regular cough medicine, they used about the same amount of extra cough medicine as those who took a fake syrup. This means the Honey Zufa might not help...

This claim says that a honey-based herbal syrup called Honey Zufa can help reduce coughing in people with mild to moderate COVID-19 better than a fake treatment, and this was measured using three...

When certain metals are mixed with citrate, they don't do much to stop viruses, so scientists think lactoferrin (a protein with metals) fights viruses in a different way than just bringing metals...

Certain forms of a protein from cow's milk are better at stopping herpes viruses from infecting cells, especially during the first steps of infection.

A protein from cow's milk, when loaded with certain minerals, can stop herpes viruses from infecting cells in a lab. It works better with more of the protein, and the amounts needed are safe for the...

Zinc lozenges and nasal gel are safe to use for treating colds in adults. They might cause minor issues like stomach upset or nose irritation, but no major problems have been found in studies.

For zinc nose sprays or drops to work well, they need to release a certain type of zinc that your body can use. If other ingredients in the product block this zinc, it won't work as well, and studies...
