CSPI participates in class action against the makers of Airborne.

According to the Center for Science in the Public Interest (CSPI), the makers of Airborne, a popular immune support supplement, will refund money to consumers who bought the product, as part of a $23.3 million class action settlement agreement. The company will pay for ads in Better Homes & Gardens, Parade, People, Newsweek, and many other magazines and newspapers instructing consumers how to get refunds.

Concocted by second-grade teacher Victoria Knight McDowell and her screenwriter husband Thomas Rider McDowell, Airborne promised to "boost your immune system to help your body combat germs" and instructed users to "take it at the first sign of a cold symptom or before entering crowded, potentially germ-infested environments." The company seemingly turned into an overnight success, especially after Ms. Knight McDowell made an appearance on the "Oprah Winfrey Show."

But in February 2006, ABC News revealed on "Good Morning America" that Airborne's much-touted lone clinical trial was actually conducted without any doctors or scientists, just a "two-man operation started up just to do the Airborne study." Soon after the plaintiff notified Airborne of his intent to file suit in March 2006, the company stopped mentioning the study and began toning down the overt cold-curing claims in favor of vague "immunity boosting" language. Next, in 2007, FTC and a group of state attorneys general began investigating the various "cold busting" claims that Airborne has made since its launch in 1999. Those investigations are continuing, since the packages' cartoony germs and suggestion for use in "school, playgrounds, airplanes" and other crowded spots still imply that Airborne is aimed at the common cold.

Airborne's basic formula contains vitamins A, C, and E, as well as other nutrients common in multivitamins; the amino acids glutamine and lysine, and an "herbal extract proprietary blend." CSPI cautions that Airborne may provide too much vitamin A, since just two pills provide 10,000 IU--the maximum safe level for a day--and the package directs customers to take three per day. In addition to several flavors of the original formula, other Airborne products include "Power Pixies," an artificially sweetened powder version for children; Airborne Seasonal, which is described as a "non-drowsy formula containing a nutritional blend that promotes normal histamine levels;" Airborne On-the-Go; and Airborne Nighttime.

"There's no credible evidence that what's in Airborne can prevent colds or protect you from a germy environment," said CSPI senior nutritionist David Schardt, who reviewed Airborne's claims. "Airborne is basically an overpriced, run-of-the-mill vitamin pill that's been cleverly, but deceptively, marketed."
