Airborne tablets do not prevent colds or flu, and the company that makes them paid a settlement for claiming they did

Airborne is a dietary supplement made from vitamins, minerals, and herbs—mostly vitamin C, zinc, and echinacea. The tablets were marketed for decades as a cold preventative, especially for travelers. In 2008, the Federal Trade Commission (FTC) found those claims were not supported by evidence and required the company to pay $23.3 million and stop making prevention claims. Today, Airborne is sold as a general wellness product, not a cold treatment or preventative.

The active ingredients in Airborne—vitamin C, zinc, and echinacea—have been studied separately. Vitamin C does not prevent colds in most people, though it may slightly shorten a cold's duration if you take it regularly before you get sick. Zinc may reduce how long a cold lasts if you take it within 24 hours of symptoms starting. Echinacea has mixed research; some studies show a small effect, others show none. None of these ingredients, alone or together in Airborne's formula, has been shown to stop you from catching a cold.

Key Takeaways

  • Airborne contains vitamin C, zinc, and echinacea, but no ingredient in the tablet has been proven to prevent colds or flu.
  • The FTC required Airborne to stop claiming it prevents colds and to pay $23.3 million for making false claims.
  • Vitamin C does not prevent colds in most people, though regular use may shorten a cold by a day or two if you already take it daily.
  • Zinc may reduce cold duration if taken within 24 hours of symptoms, but Airborne is not designed to be taken that way.
  • Washing your hands regularly and avoiding people who are sick are the most effective ways to reduce your risk of catching a cold.

What the FTC settlement means

In 2008, the FTC challenged Airborne's marketing claims that the tablets could prevent colds and flu. The company had advertised that Airborne could stop you from getting sick if you took it before traveling or being around sick people. The FTC found no scientific evidence supporting those claims and required Airborne to pay $23.3 million—one of the largest settlements for false health claims at that time.

As part of the settlement, Airborne agreed to stop making any claim that the product prevents, treats, or reduces the risk of catching a cold or flu. The company also agreed that future advertising would need to be backed by competent scientific evidence. Today, Airborne is labeled and sold as a dietary supplement for general wellness, not as a cold preventative.

What research actually shows about the ingredients

Vitamin C: Multiple large studies have found that taking vitamin C does not prevent colds in the general population. If you take vitamin C every single day before you get sick, it may shorten a cold by about a day, but it will not stop you from catching one. Taking vitamin C after symptoms start does not help. Airborne contains 167 mg of vitamin C per tablet, which is less than the recommended daily amount for adults (75–90 mg for most people, up to 2,000 mg daily is considered safe).

Zinc: Zinc may reduce how long a cold lasts if you take it within 24 hours of your first symptom. Some studies show it can shorten a cold by 2–3 days. However, Airborne is meant to be taken before you are sick, not after symptoms appear, so this benefit would not explore to how most people use the product. Long-term zinc use can cause problems, so it is not meant to be taken daily as a preventative.

Echinacea: Research on echinacea is mixed. Some studies show a small reduction in cold duration or severity, while others show no effect. The evidence is not strong enough to say echinacea reliably prevents or treats colds. Airborne contains echinacea extract, but the amount and type vary by formulation.

How Airborne is actually used versus how it was marketed

Airborne was originally sold as a tablet you would dissolve in water and drink before traveling or when you felt a cold coming on. The marketing suggested that taking it regularly during travel season would keep you from getting sick. This is the claim the FTC found unsupported.

Today, Airborne is still sold the same way—as a dissolvable tablet with vitamins and herbs. But the packaging and advertising no longer claim it prevents colds. Instead, it is marketed as a general wellness supplement. Some people take it anyway hoping it will help, but there is no scientific reason to expect it to prevent illness.

What actually reduces your risk of catching a cold

The most effective ways to avoid catching a cold are straightforward and do not require supplements. Washing your hands frequently with soap and water for at least 20 seconds is the single most effective prevention method. Avoid touching your face, especially your eyes, nose, and mouth. Stay away from people who are actively sick, and if you are sick, stay home to avoid spreading illness to others.

If you are concerned about your health during travel or high-stress periods, talk to your doctor about what actually works for your situation. Getting enough sleep, eating a balanced diet, staying hydrated, and managing stress all support your immune system more reliably than any single supplement.

Why Airborne is still sold if it does not work

Airborne remains on store shelves because it is a dietary supplement, not a drug. The FDA regulates supplements differently than medications. A supplement does not have to prove it works before it is sold; the company only has to make sure it is safe and that any claims are truthful. Since Airborne stopped making prevention claims after the FTC settlement, it can legally be sold as a general wellness product.

The supplement industry is large and profitable. Many people buy Airborne out of habit, because they remember the old marketing, or because they hope it might help even if they know the evidence is weak. The company is allowed to sell it as long as it does not claim the product prevents or treats disease.

Frequently Asked Questions

Does Airborne work if I take it when I feel a cold starting?

No. Airborne is not formulated to be taken after symptoms start, and the ingredients it contains have not been shown to work that way. If you want to try zinc, which has some evidence for shortening a cold, you would need a different product taken within 24 hours of your first symptom—not Airborne.

Is Airborne safe to take every day?

Airborne is generally safe for occasional use, but taking it every day is not recommended. The zinc content could build up in your system over time, and long-term daily zinc use can cause problems. Talk to your doctor before taking any supplement regularly.

Why did the FTC sue Airborne if it is still being sold?

The FTC sued because Airborne was making false claims that it prevented colds. The settlement required the company to stop those claims and pay a penalty. The product itself is not illegal; the false advertising was the problem. Airborne can still be sold as a wellness supplement as long as it does not claim to prevent disease.

What is the difference between Airborne and other cold prevention supplements?

Most cold prevention supplements contain similar ingredients—vitamin C, zinc, and herbs like echinacea or elderberry. None of them have strong evidence for preventing colds. The main difference is marketing and price. Airborne is well-known because of its old advertising, but that does not mean it works better than other options or no supplement at all.

Should I take Airborne before traveling?

There is no scientific reason to take Airborne before traveling. If you want to reduce your risk of getting sick while traveling, focus on washing your hands often, avoiding touching your face, and staying away from visibly sick people. Getting enough sleep and staying hydrated also support your immune system better than any supplement.
