I must say that as an Airborne user, I really feel the product has helped me get better and avoid and/or shorten the duration of colds. Others disagree and have sued Airborne and the class-action lawsuit just settled for $23.3 million..
Here is an excerpt from a CNN article on the lawsuit:
"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. "Airborne is basically on overpriced, run-of-the-mill vitamin pill that’s been cleverly, but deceptively, marketed."
According to the company’s Web site, Airborne was created by second-grade teacher, Victoria Knight-McDowell, who "studied the benefits herbal therapies used in Eastern Medicine." The site says Airborne "boosts the immune system with seven herbal extracts and a proprietary blend of vitamins, electrolytes, amino acids and antioxidants."
I feel bad for suggesting this supplement in a past entry but I still feel this product works for me and yes, I know it is overpriced vitamins but I also think my car is overpriced.
