Zinc lozenges, saline irrigation, and honey show evidence for cold relief, but formulations matter.
Evidence supports zinc acetate lozenges, saline nasal irrigation, and honey for reducing cold duration and symptoms, though zinc formulation is critical.

19 claims, each mapped to its moment in the video
This claim says that taking lots of vitamin C, echinacea, garlic, or vitamin D doesn't actually help you get better from a cold, according to real studies done on people.
Evidence points in both directions — no clear conclusion yet.
Zinc can stop cold viruses from copying themselves and spreading in lab tests.
Multiple causal studies (randomized trials and reviews) support this claim.
Zinc can stop viruses from copying themselves and spreading in lab tests, even for cold viruses.
Weak evidence — fewer than 20 studies, so treat this as a starting point, not a fact.
Citric acid and some sweeteners stick to zinc particles and stop them from fighting viruses.
Not enough evidence yet — take this with caution.
Different zinc lozenges have different amounts of the active form of zinc, and only the active form fights viruses.
Evidence contradicts this claim.
Different zinc lozenges let your body absorb zinc differently. Some, like zinc acetate, let you use all the zinc, while others don't let you use any at all.
Weak evidence — fewer than 20 studies, so treat this as a starting point, not a fact.
Taking zinc acetate lozenges when you have a cold can help you get better faster, cutting down how long you're sick by about 2 to 3 days.
Multiple causal studies (randomized trials and reviews) support this claim.
Taking zinc acetate lozenges when you have a cold might help you get better faster, cutting down how long you're sick by about 2 to 3 days.
Good evidence supports this claim, with little to contradict it.
Taking special high-strength zinc lozenges when you have a cold can help you get better about three days faster.
Good evidence supports this claim, with little to contradict it.
Taking zinc lozenges when you have a cold might help you get better faster, cutting down how long you're sick by about one-third.
Evidence contradicts this claim.
Cells in your breathing tubes make a natural cleaning chemical that kills viruses when they try to infect you.
Weak evidence — fewer than 20 studies, so treat this as a starting point, not a fact.
Your nose and breathing tubes have special cells that make a natural cleaning chemical to kill viruses when you get sick.
Weak evidence — fewer than 20 studies, so treat this as a starting point, not a fact.
When you get a virus, your breathing cells need a certain chemical (chloride) to make a germ-fighting acid. If there's not enough of this chemical, your body might not fight off the virus as well.
Weak evidence — fewer than 20 studies, so treat this as a starting point, not a fact.
Rinsing your nose with salt water gives your nose cells what they need to make a natural germ-fighting chemical, which helps your body fight off viruses better.
Multiple causal studies (randomized trials and reviews) support this claim.
Rinsing your nose with salt water gives your nose cells a special ingredient that helps them make a natural germ-fighting acid to fight off viruses.
Multiple causal studies (randomized trials and reviews) support this claim.
Using saltwater nose rinses can help you get over a cold faster, cut down on how much medicine you need, and make it less likely to spread the cold to others in your home.
Evidence points in both directions — no clear conclusion yet.
Honey helps people with colds feel better overall, cough less often, and have less severe coughs than usual treatments, according to medical studies.
Strong evidence from clinical studies backs this claim.
Honey helps people with colds or coughs feel better by reducing how often they cough and how bad their cough is, compared to regular treatments.
Good evidence supports this claim, with little to contradict it.
A nose spray with nitric oxide can quickly kill over 99% of flu, COVID, and cold viruses in lab tests.
Not enough evidence yet — take this with caution.
